Hydroxypinacolone Retinoate (HPR)

A direct retinoid ester that doesn't require enzymatic conversion — more bioavailable and less irritating than traditional retinol, making it ideal for retinoid newcomers and sensitive skin types.

Hydration-First Formula

Sodium Hyaluronate (HA), Oat Beta-Glucan, and Glycerin work together to attract and lock in moisture, preventing the dryness and peeling associated with most retinoid products.

Phytoceramide Barrier Support

Hydrolyzed Soybean Palmitate delivers plant-derived ceramides that reinforce the skin's lipid barrier, reducing sensitivity and helping actives penetrate more effectively.

Clean Beauty Standard

EWG Verified and Leaping Bunny certified. Free from parabens, SLS, phthalates, synthetic dyes, petrochemicals, silicones, and PEGs. Vegan and cruelty-free with eco-conscious packaging.

Multi-Benefit Anti-Aging

Targets fine lines, wrinkles, uneven skin tone, hyperpigmentation, age spots, and rough texture simultaneously — a comprehensive anti-aging treatment in a single dropper.

Enhanced Delivery System

Dimethyl Isosorbide (DMI) acts as a penetration enhancer, helping active ingredients including HPR and Hyaluronic Acid reach deeper skin layers for more pronounced, long-lasting results.

Safety & compatibility

SAFE
Pregnancy & Breastfeeding: Not Recommended

This serum contains Hydroxypinacolone Retinoate, a retinoid (Vitamin A derivative). All topical retinoids are advised against during pregnancy and breastfeeding. Mad Hippie themselves state: "Our Super A Serum does contain vitamin A, an ingredient typically advised against during that time." Always consult your healthcare provider and consider pregnancy-safe alternatives like Vitamin C or Niacinamide serums.

Fungal Acne (Malassezia): Use With Caution

The formula contains Cocos Nucifera (Coconut) Oil, which has a higher comedogenic potential and may feed Malassezia yeast. It also contains Stearyl Alcohol (a fatty alcohol that can be problematic for some FA-prone individuals). Safflower Seed Oil (Carthamus Tinctorius) is generally FA-safe due to its high linoleic acid content. Patch test recommended if you have active fungal acne.

Comedogenic Rating: 2/5 — Generally Non-Comedogenic

Safflower seed oil rates 0-2 (low), Coconut oil rates 4 (higher risk), but it appears lower in the formula. Overall comedogenic risk is low for most skin types. HPR itself is noted to help reduce clogged pores and prevent breakouts.

Parabens, SLS, Phthalates: Free

Mad Hippie formulates without parabens, sodium lauryl sulfate, phthalates, petrochemicals, silicones, PEGs, synthetic dyes, or synthetic fragrance. EWG Verified status confirms this clean ingredient profile.

Sun Sensitivity: SPF Required

Retinoids increase photosensitivity. Mad Hippie explicitly states this product "might cause increased sensitivity to the sun." Always wear broad-spectrum SPF 30+ in the morning after nighttime use. Never apply this serum in the morning without sun protection.

Sensitive Skin: Beginner-Friendly Retinoid

HPR is considered a gentler retinoid versus traditional retinol or tretinoin as it doesn't require conversion steps in the skin. Multiple users with eczema and sensitive skin report tolerating this serum well. Start every other night and increase frequency as skin adjusts.

Vegan & Cruelty-Free

Leaping Bunny certified cruelty-free. 100% vegan formula — no animal-derived ingredients. Mad Hippie also donates a portion of web sales to environmental conservation organizations.

Compatible With: Niacinamide, Peptides, HA

Works well with hydrating and barrier-supporting ingredients. Avoid layering with other strong exfoliants (AHAs, BHAs) on the same night. Can alternate nightly with Mad Hippie's own AHA Exfoliating Peel for a gentle resurfacing routine.

Ingredient breakdown

INGREDIENTS

Hydroxypinacolone Retinoate (HPR) ~0.05–0.15%Proven

Also known as Granactive Retinoid, HPR is a direct ester of retinoic acid — meaning it binds to retinoid receptors without requiring enzymatic conversion. Unlike retinol which must go through multiple conversion steps to become active, HPR is bioavailable as formulated, making it highly effective yet significantly gentler.

  • Mechanism: Directly binds retinoic acid receptors (RARs) in the skin, stimulating collagen production and accelerating cell turnover
  • Efficacy vs Retinol: Manufacturer studies on human skin models show HPR outperforms retinol, retinaldehyde, and retinyl palmitate in efficacy markers
  • Irritation Profile: Significantly lower irritation potential vs traditional retinol due to its ester form — no conversion steps means less free retinoic acid release
  • Benefits: Reduces appearance of fine lines, wrinkles, hyperpigmentation, age spots, uneven texture, and enlarged pores
Not safe during pregnancy or breastfeeding. Start slowly — every other night — if new to retinoids. Always follow with SPF the next morning.

Sodium Hyaluronate (Hyaluronic Acid) ~0.90–1.35%Proven

The sodium salt form of hyaluronic acid, Sodium Hyaluronate has a smaller molecular weight than standard HA, allowing it to penetrate deeper into the skin to provide hydration at multiple levels. A powerful humectant capable of holding up to 1,000x its weight in water.

  • Function: Draws moisture from the environment and deeper skin layers to the surface, maintaining optimal skin hydration
  • Anti-aging: Plumps fine lines and wrinkles by restoring moisture volume in the skin
  • Compatibility: Works synergistically with retinoids — helps counteract potential dryness from HPR
Safe for all skin types including sensitive, pregnancy-safe, and fungal acne safe.

Beta-Glucan (Oat Beta-Glucan) ~0.5–1%Proven

A polysaccharide derived from oat grain, Beta-Glucan is one of the most powerful soothing and barrier-repairing ingredients in skincare. It also acts as a humectant and has been shown to stimulate collagen synthesis, making it a true multi-tasker in anti-aging formulas.

  • Soothing: Clinically shown to reduce redness, irritation, and inflammation — ideal for counteracting retinoid sensitivity
  • Barrier Support: Helps reinforce the skin's natural moisture barrier, reducing transepidermal water loss (TEWL)
  • Collagen: Research shows beta-glucan stimulates fibroblast activity, supporting collagen production alongside retinoids
Safe for all skin types. Especially beneficial for sensitive or reactive skin alongside retinoid ingredients.

Hydrolyzed Soybean Palmitate (Phytoceramide) ~0.2–0.5%Proven

A plant-derived ceramide precursor extracted from soybeans. Ceramides are the "mortar" of the skin's barrier — they fill the gaps between skin cells to prevent moisture loss and protect against environmental stressors. Hydrolyzed Soybean Palmitate replenishes ceramide levels depleted by age, harsh weather, or active ingredients.

  • Barrier Repair: Restores and strengthens the skin's lipid barrier, reducing sensitivity caused by retinoid use
  • Moisture Retention: Ceramides are essential for preventing transepidermal water loss — critical when using active ingredients
  • Anti-aging: Ceramide levels naturally decline with age; topical replenishment improves skin firmness and elasticity
Generally safe for all skin types. Vegan plant-derived source from soybeans.

Cocos Nucifera (Coconut) Oil ~1–2%Promising

Cold-pressed coconut oil is a rich emollient loaded with lauric acid (medium-chain fatty acid) with known antimicrobial and moisturizing properties. In this serum it helps create a smooth, slightly occlusive texture and supports skin softness.

  • Emollient: Softens and smooths skin surface, improving the sensory experience of the serum
  • Antimicrobial: Lauric acid has demonstrated antimicrobial activity, potentially beneficial for acne-prone skin
  • Comedogenicity: Rated 4/5 on comedogenic scale — may clog pores for some, particularly if used in high concentrations
Higher comedogenic rating (4/5). May trigger breakouts or feed Malassezia for fungal acne-prone individuals. It appears lower in the ingredient list suggesting a lower concentration.

Carthamus Tinctorius (Safflower) Seed Oil ~1–2%Proven

A lightweight, high-linoleic acid plant oil extracted from safflower seeds. With approximately 70% linoleic acid content, safflower oil is one of the most skin-compatible oils — particularly beneficial for acne-prone skin, which is often deficient in linoleic acid.

  • Linoleic Acid (70%): Restores skin barrier integrity; low-linoleic skin is more prone to clogged pores and breakouts
  • Antioxidant: Contains Vitamin E (alpha-tocopherol, 44mg/100g) providing antioxidant protection against free radical damage
  • Comedogenicity: Rates 0-2 — very low risk of clogging pores, making it excellent for acne-prone skin
Low comedogenic rating (0-2). Generally considered fungal acne safe due to its fatty acid composition.

Acetyl Glucosamine ~1.10–1.70%Proven

A skin-identical amino sugar and precursor to hyaluronic acid synthesis. Unlike regular glucosamine, the acetylated form is more stable and penetrates the skin more effectively. It has been shown in studies to reduce hyperpigmentation and improve skin texture.

  • Brightening: Inhibits tyrosinase enzyme activity, reducing melanin production and the appearance of dark spots
  • Hydration: Acts as a precursor to Hyaluronic Acid synthesis, boosting the skin's natural HA production
  • Texture: Promotes healthy skin cell turnover, improving overall skin smoothness and clarity
Well tolerated by most skin types. Works synergistically with retinoids for enhanced hyperpigmentation reduction.

Dimethyl Isosorbide (DMI) ~1–3%Proven

A highly purified solvent and penetration enhancer that helps active ingredients — particularly HPR and Hyaluronic Acid — penetrate deeper into the skin. DMI is valued in advanced formulations for its ability to improve the bioavailability of actives without causing irritation.

  • Penetration: Enhances skin absorption of co-formulated actives, making the HPR retinoid more effective
  • Solubilizer: Helps dissolve and stabilize the HPR molecule in the water-based formula
  • Compatibility: Non-irritating carrier with an excellent safety profile, widely used in pharmaceutical and cosmetic applications

Citrus Aurantium Dulcis Peel Oil (Sweet Orange Peel Oil) tracePromising

Steam-distilled essential oil from sweet orange peel. This is the source of the serum's light, pleasant citrus scent. While technically a fragrant component, the trace amount used and steam-distillation method result in minimal irritation risk for most users.

  • Antioxidant: Contains limonene and flavonoids with free radical-scavenging activity
  • Sensory: Provides the serum's characteristic light citrus/floral scent — makes the product pleasant to use nightly
  • Concentration: Present at trace levels (near end of ingredient list) — irritation risk is very low
Technically a fragrant ingredient — those with extreme fragrance sensitivity or citrus allergies should patch test. Overall risk is low given trace concentration.

How to use

HOW TO USE
1

Cleanse Thoroughly

Start with clean, dry skin. Use a gentle, pH-balanced cleanser to remove makeup, sunscreen, and daily impurities. Pat skin dry — do not apply to wet skin as this can increase irritation potential.

2

Apply Toner or Essence (Optional)

If your routine includes a hydrating toner or essence, apply it first to prep and pre-hydrate the skin. This can also help buffer the retinoid for sensitive skin types.

3

Dispense 2–4 Drops

Shake gently and dispense 2–4 drops of the serum onto clean fingertips. A little goes a long way — start with 2 drops for your first applications. One bottle typically lasts 2–3 months with consistent use.

4

Massage Into Face & Neck

Gently massage the serum into face and neck in upward, circular motions. Avoid the immediate eye area. Allow the formula to absorb for approximately 30 seconds before the next step.

5

Follow With Moisturizer (Essential)

Always seal with your favorite moisturizer immediately after. This step is non-negotiable — it locks in the actives, reduces potential dryness, and prevents TEWL. Mad Hippie recommends their own moisturizing cream as a follow-up.

6

Frequency: Start Every Other Night

If you are new to retinoids, begin with every other night for 2–4 weeks. Gradually increase to nightly use as your skin acclimates. Even experienced retinoid users may want to start cautiously with a new formula. Always wear SPF the following morning.

06

Skin type compatibility

SKIN TYPES
Normal Skin
Excellent

Ideal match. The balanced formula delivers HPR retinoid benefits without disrupting normal skin's equilibrium. Hydrating actives maintain moisture while HPR works on texture and tone.

Dry Skin
Good

HA, Beta-Glucan, and phytoceramides provide meaningful hydration. Dry skin types should always follow with a rich moisturizer and may consider the "sandwich method" (moisturizer before and after) during the adjustment phase.

Oily Skin
Good

HPR helps regulate sebum and reduce enlarged pores. The milky texture absorbs well without leaving excess residue. Note that Coconut Oil is present — monitor for any increased congestion in very oily skin types.

Combination Skin
Excellent

One of the best skin types for this formula. HPR addresses oily zones while HA and ceramides hydrate drier areas. The lightweight milky texture balances well across different facial zones.

Sensitive Skin
Good

HPR is the gentlest form of retinoid available OTC. Beta-Glucan and phytoceramides actively soothe and protect. Users with eczema report tolerating this serum well. Start every third night and patch test first.

Acne-Prone Skin
Good

HPR actively reduces clogged pores and breakouts. Safflower oil (high linoleic acid) is skin-beneficial for acne-prone skin. Main caution is the Coconut Oil which rates higher on the comedogenic scale — monitor your skin's response.

Budget-friendly alternatives (dupes)

DUPES
82% Match
Granactive Retinoid 2% Emulsion
$9.90
Budget Pick

Uses the same HPR (Granactive Retinoid) active ingredient at 2% emulsion concentration. Simpler base formula without the soothing phytoceramides and Beta-Glucan found in Mad Hippie's version. Less hydrating and luxurious, but delivers the same core retinoid active at a fraction of the price.

72% Match
1% Retinol Booster
$52.00

Uses traditional retinol (1%) rather than HPR — may cause more initial irritation but delivers well-researched, proven anti-aging results. More thoroughly clinical formula with added antioxidants. Higher price point but beloved by dermatologists for its efficacy. Good option if you want to step up retinoid potency.

68% Match
Retinol Correxion Line Smoothing Night Serum Capsules
$22.00
Similar Price

Drugstore retinol option with decades of clinical data supporting its efficacy. Uses classic retinol rather than HPR — may be slightly more irritating to start. Not clean beauty formulated (contains mineral oil and fragrance). Good for those who want a more widely available alternative at a similar price point.

Frequently asked questions

FAQ

No — Mad Hippie Vitamin A Serum is not recommended during pregnancy or breastfeeding. It contains Hydroxypinacolone Retinoate (HPR), a form of Vitamin A (retinoid). All topical retinoids are typically advised against during pregnancy due to the potential risks associated with high Vitamin A intake. Mad Hippie explicitly acknowledges this on their own website, stating the serum "contains vitamin A, an ingredient typically advised against during that time." They recommend pregnancy-safe alternatives such as their Vitamin C Serum or Corrective Peptide Serum. Always consult your healthcare provider or OB-GYN before using any retinoid product while pregnant or nursing.

Use with caution if you have active fungal acne. The formula contains Cocos Nucifera (Coconut) Oil, which has a high comedogenic rating and may feed Malassezia yeast, potentially worsening fungal acne. It also contains Stearyl Alcohol (a fatty alcohol) which some fungal acne-prone individuals react to. On the positive side, Safflower Seed Oil (Carthamus Tinctorius) is generally considered fungal acne safe due to its high linoleic acid content. If you have active malassezia folliculitis, it may be safer to choose an alternative serum with a clearly FA-safe ingredient list until your condition is under control. Patch testing is strongly recommended.

The Mad Hippie Vitamin A Serum already contains a retinoid (HPR), so do not layer additional retinol products on the same night — this can cause over-exfoliation and irritation. Regarding Vitamin C: use Vitamin C in the morning and the Vitamin A Serum at night (PM only) — they work synergistically as a morning/night pair. For AHAs and BHAs: avoid using them on the same night as this retinoid serum, especially while your skin is still adjusting. Once acclimated, you can alternate nightly (retinoid one night, AHA/BHA the next). Mad Hippie themselves suggest alternating with their AHA Exfoliating Peel. Niacinamide and peptide serums are compatible and can be layered in the same routine if applied before the serum.

Mad Hippie Vitamin A Serum is best suited to normal, combination, and sensitive skin types, and is a particularly excellent choice for anyone who is new to retinoids or has previously had irritation with traditional retinol. The gentle HPR retinoid delivers real anti-aging results without the harshness. People with oily and acne-prone skin can also benefit, as HPR helps regulate oil and reduce breakouts — though the presence of Coconut Oil is worth monitoring. Dry skin types benefit from the hydrating ingredients but may need a richer moisturizer on top. Those with active fungal acne should exercise caution. All skin types looking for a clean, vegan, anti-aging retinoid treatment will find this formula appealing.

Initial improvements in skin hydration and softness are typically noticeable within the first 1–2 weeks of use. Visible texture improvement (smoother, more refined skin) generally appears around weeks 3–4. The deeper anti-aging effects — reduction of fine lines, fading of hyperpigmentation and age spots, improved skin firmness — typically require consistent nightly use for 6–12 weeks. This timeline applies to all retinoid products, including gentler forms like HPR, because the changes happen in the deeper layers of the skin. Mad Hippie recommends consistent use for best results. For hyperpigmentation specifically, allow at least 2–3 months of consistent use for meaningful results.

Mad Hippie Vitamin A Serum is a PM-only product (never use retinoids in the morning without heavy SPF protection). Apply it as step 4 in your evening routine: after cleansing, toning, and any essence, but before your moisturizer. The correct order is: Cleanser → Toner/Essence → Vitamin A Serum → Moisturizer. The following morning, always apply a broad-spectrum SPF 30+ sunscreen as retinoids increase photosensitivity. Do not use this on the same night as AHA or BHA exfoliants until your skin has adjusted to the retinoid. A helpful schedule: Retinoid every other night, alternating with a hydrating serum or AHA on alternate nights.

Mad Hippie Vitamin A Serum has an overall comedogenic rating of approximately 2/5, which is considered low to moderate. The majority of the ingredients are non-comedogenic: Safflower Seed Oil rates 0-2 (excellent for acne-prone skin), Sodium Hyaluronate rates 0, Glycerin rates 0, and Beta-Glucan is non-comedogenic. The main ingredient to be aware of is Cocos Nucifera (Coconut) Oil, which rates 4/5 on the comedogenic scale. However, Coconut Oil appears lower in the ingredient list, suggesting it's present in smaller concentrations. The HPR retinoid itself is actually known to help reduce clogged pores and breakouts. Most users, including those with oily and acne-prone skin, tolerate this serum well without increased congestion.

Mad Hippie Vitamin A Serum has a recommended Period After Opening (PAO) of 12 months. The 30ml bottle typically lasts 2–3 months with regular use (2–4 drops every other night). To preserve potency, store the bottle away from direct sunlight, heat, and humidity — avoid bathroom storage if possible. Retinoids are sensitive to light and air degradation, so always close the dropper tightly after each use. The glass dropper bottle helps protect the HPR from light exposure. If the serum changes color significantly (from its light cream/yellow color to deep orange or brown), it may have oxidized and should be discarded.

— Skincarisma verdict
4.4 / 5 ★★★★☆

Verdict: Mad Hippie Vitamin A Serum stands out as one of the best entry points into retinoid skincare for clean beauty enthusiasts. Its use of Hydroxypinacolone Retinoate (HPR) — a bioavailable, direct retinoid ester — delivers meaningful anti-aging results with significantly less irritation than traditional retinol, making it genuinely accessible for sensitive and retinoid-naive skin types. The inclusion of Sodium Hyaluronate, Oat Beta-Glucan, and phytoceramides from Hydrolyzed Soybean Palmitate creates a hydration-forward base that actively fights the dryness and peeling that discourages so many people from sticking with retinoid routines. The EWG Verified, Leaping Bunny certified, vegan formula is among the cleanest available at its price point. While not a prescription-strength treatment and not suitable during pregnancy, for the everyday consumer seeking visible improvements in texture, fine lines, and skin tone through a clean, gentle, sustainable product, Mad Hippie Vitamin A Serum consistently delivers.

lightbulb What is the Ingredient Safety Breakdown?

Ingredient Safety Breakdown refers to the percentage % of ingredients in different risk categories as classified by EWG (Environment Working Group) if they are available. There are almost endless cosmetic ingredients and they are one of the few organisations globally that have assigned ratings to a lot of the more commonly used ingredients which is why we reference them.

muscle Pro Tip Alert!

EWG is seen by many to be more on the alarmist side in their assignment of health ratings resulting in rating ingredients as riskier than they actually are. We recommend using this a reference point rather than a strict guide of ingredient safety and to always do further research if into ingredients that you may find suspect.
