Product Description

From Face Reality Skincare, the 11% L-Mandelic Serum is a clinical-grade exfoliating treatment powered by 11% L-Mandelic and 8% L-Lactic acid. This lightweight, water-based formula gently sweeps away dead skin cells to clear acne and folliculitis, fade post-acne marks, and reveal brighter, smoother-looking skin β€” with less irritation than harsher AHAs.

Dual-Acid Exfoliation

11% L-Mandelic and 8% L-Lactic acid work together to sweep away dead cells, smooth texture and refine the look of pores.

🦠

Antibacterial & Antifungal

Mandelic acid is one of the few AHAs that targets both acne bacteria and fungal folliculitis (malassezia).

✨

Brightens & Evens Tone

Accelerates surface cell turnover to fade post-acne marks, dark spots and dullness for a clearer complexion.

πŸͺΆ

Gentle by Design

Mandelic's larger molecule penetrates slowly, delivering even exfoliation with less irritation than glycolic acid.

πŸ›‘οΈ Safety & Compatibility

⚠️
Pregnancy & Breastfeeding

Mandelic acid is considered one of the gentler, lower-risk AHAs, but this is a strong 11% leave-on formula β€” check with your doctor first.

βœ…
Fungal Acne (Malassezia)

Rated malassezia-safe; mandelic acid is actively antifungal and recommended for fungal folliculitis.

β˜€οΈ
Sun Sensitivity

AHAs increase photosensitivity. Use only at night and apply broad-spectrum SPF every morning.

βœ…
Non-Comedogenic

Lightweight, water-based formula that won't clog pores β€” suitable for acne-prone skin.

⚠️
Can Be Drying

Contains denatured alcohol. Introduce slowly (2-3x per week) and buffer with moisturizer as needed.

πŸ”„
Layering Actives

Avoid pairing with retinoids, benzoyl peroxide or other strong acids on the same night to prevent over-exfoliation.

πŸ”¬ Ingredient Breakdown

πŸ‘ L-Mandelic Acid 11% Proven

An alpha-hydroxy acid derived from bitter almonds. It exfoliates the surface, unclogs pores and visibly brightens tone β€” and is uniquely antibacterial and antifungal.

  • Molecular size: Larger than glycolic acid, so it penetrates slowly for even exfoliation with less irritation.
  • Chirally correct (L): Uses the skin-recognised form for more predictable, effective results.
  • Clinical use: Targets inflamed and non-inflamed acne, folliculitis and post-acne pigmentation.
βœ…
One of the few exfoliating acids recommended for both acne and fungal folliculitis.

πŸ₯› L-Lactic Acid 8% Proven

A second AHA that exfoliates while also acting as a humectant, helping the formula hydrate as it resurfaces.

  • Dual action: Loosens dead-cell bonds and draws water into the skin at the same time.
  • NMF component: Lactic acid is part of skin's natural moisturising factor.
⚠️
Increases sun sensitivity β€” daily SPF is essential while using this serum.

🧬 Niacinamide Proven

Vitamin B3 β€” a multitasker that calms inflammation, regulates oil, strengthens the barrier and brightens uneven tone.

  • Barrier support: Boosts ceramide production for a stronger, more resilient skin barrier.
  • Tone & oil: Helps fade discolouration and balance sebum, easing the dryness acids can cause.

πŸ’§ Hydration Complex HA Β· PCA Β· Urea Proven

Sodium Hyaluronate, Sodium PCA and Urea form a humectant trio that replenishes moisture and offsets the drying potential of the acids.

  • Sodium Hyaluronate (L): Low-molecular-weight HA that attracts and holds water in the skin.
  • Sodium PCA & Urea: Skin-identical humectants that keep skin supple during exfoliation.

🌿 Witch Hazel Water Promising

Hamamelis Virginiana water forms an astringent, antioxidant base that helps tighten the look of pores.

  • Active compounds: Contains tannins and catechins with antioxidant and soothing properties.
⚠️
Astringent by nature β€” combined with the alcohol base, it can feel drying on already-dry skin.

SPF (AM)

Use at night on clean, dry skin. Apply the mandelic serum before heavier hydrators so the acids can work directly on the skin, then seal with moisturizer. Never skip morning SPF.

πŸ“ How to Use

1

Patch Test & Start Slow

Begin with 2-3 nights per week and build up frequency as your skin adjusts to the acids.

2

Apply to Clean, Dry Skin

Press 1-2 pumps over the face or affected areas in the evening, avoiding the immediate eye area.

3

Let It Absorb, Then Moisturize

Wait about a minute, then follow with a hydrating serum and moisturizer to buffer any dryness.

4

Protect with SPF Daily

AHAs increase sun sensitivity, so apply broad-spectrum SPF 30+ every morning without fail.

πŸ‘€ Who Is It For?

❓ Frequently Asked Questions

Mandelic acid is considered one of the gentler, lower-risk AHAs and is often suggested as a salicylic-acid alternative during pregnancy. However, this is a strong 11% leave-on formula, so most experts advise checking with your OB-GYN or dermatologist before using it while pregnant or breastfeeding.

Yes. It's rated malassezia-safe, and mandelic acid is actively antifungal β€” the brand even recommends this serum for fungal folliculitis, making it a strong choice for fungal-acne-prone skin.

Use it on its own at night rather than layering it with retinoids, benzoyl peroxide or other strong acids on the same evening, to avoid over-exfoliation. Many people alternate nights, and vitamin C is best kept to the morning routine.

It performs best on oily, combination and acne-prone skin dealing with congestion, folliculitis or uneven tone. Dry or sensitive types can use it cautiously by starting at a lower frequency and buffering with moisturizer.

Many users notice smoother, brighter skin within 1-2 weeks, with clearer skin and visibly fading marks over 4-12 weeks of consistent use.

At night, after cleansing, on clean dry skin β€” before your hydrating serum and moisturizer. Always follow with broad-spectrum SPF the next morning, since AHAs increase sun sensitivity.

No. It's a lightweight, water-based, non-comedogenic formula (comedogenic rating around 1/5) specifically designed for acne-prone and congested skin.

Roughly 12 months after opening. Store it in a cool, dry place away from direct light to help preserve the potency of the acids.

Verdict: Face Reality's 11% L-Mandelic Serum is a clinical-grade, hard-working exfoliant that does what few acids can β€” clear acne and fungal folliculitis while fading marks and refining texture, all with the gentler feel of mandelic acid. The trade-offs are a drying alcohol base and a small, professional-tier price, so it's best for oily, combination and acne-prone skin that can commit to slow introduction and daily SPF. For the right skin, it's one of the most effective multitasking exfoliants available.

question
lightbulb What are Notable Effects & Ingredients?

Ever used a product that promised a certain effect but provided no results? It might not have contained any notable ingredients that could have been responsible for that promised effect. It doesn't matter what the marketing or packaging Β«promisesΒ» it can do, if it doesn't contain anything that can help - then the likelihood of it helping is low.

We help you identify key notable ingredients that have been shown to help with effects such as acne-fighting, brightening, UV-protection, wound healing & anti-aging to help you achieve your skincare goals smarter. Please note that different notable ingredients have varying levels of research behind them, some are extremely well proven yet some have mixed research in their efficacy.

muscle Pro Tip Alert!

Just because a product doesn't contain any notable ingredients doesn't mean it's bad. And a product with notable ingredients (or even many) doesn't necessarily guarantee the efficacy of the product performing these effects either. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine this.

Be smart and use this as just a starting point for you to make more informed and smarter choices and compare it with reviews to see if the product is right for you

lightbulb What are Ingredients Related to Skin Type?

Why are some products great for some people and horrible for others? Well everyone has different skin types and different reactions to the same ingredients.

We've identified a range of ingredients that are commonly regarded as potentially good or bad for those with Dry, Oily/Acne-Prone or Sensitive skin.

A product that contains good or bad ingredients for your skin type doesn't always flat out make the entire product good or bad for your skin. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine your skins reaction.

One of the best ways to use this section is to troubleshoot products you've had bad experiences with in the past. Check if it contains any of the marked ingredients to point out suspect ingredients to avoid in the future!

question
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.
