Ingredient breakdown
INGREDIENTSRetinol 0.3%Proven
The gold-standard anti-aging ingredient. This nano-sized, encapsulated form of Vitamin A penetrates deeper layers of skin for optimum results while remaining stable and less irritating than traditional retinol.
- Anti-Aging: Stimulates collagen production and accelerates cell turnover to reduce fine lines and wrinkles.
- Acne-Fighting: Normalizes keratinization and reduces sebum production, helping to keep pores clear.
- Brightening: Fades dark spots and evens out skin tone over time by promoting faster skin renewal.
- Concentration: 0.3% is a moderate-low dose ideal for beginners and sensitive skin, while still delivering visible results.
Niacinamide ~3-5%Proven
A multi-functional form of Vitamin B3 that brightens skin, regulates oil production, and strengthens the skin barrier. Works synergistically with retinol to enhance anti-aging and brightening results.
- Barrier Support: Increases ceramide production, reinforcing the skin barrier that retinol can weaken.
- Oil Control: Regulates sebum secretion, helping to reduce shine and minimize pores.
- Brightening: Inhibits melanosome transfer to reduce dark spots and improve overall skin tone.
Alpha-Arbutin ~1-2%Proven
A potent skin-brightening agent derived from bearberry plant. Works by inhibiting the tyrosinase enzyme responsible for melanin production, making it effective for fading hyperpigmentation and dark spots.
- Melanin Inhibition: Blocks tyrosinase more effectively than beta-arbutin, reducing dark spot formation.
- Synergy: Works synergistically with retinol, niacinamide, and vitamin C for enhanced brightening results.
- Gentle: Considered safer and gentler than hydroquinone for long-term brightening use.
Avena Sativa (Oat) Meal Extract Mid-RangeProven
A well-studied soothing ingredient that calms irritation, protects the skin barrier, and provides anti-inflammatory benefits. An ideal partner for retinol to reduce the risk of redness and sensitivity.
- Anti-Inflammatory: Contains avenanthramides, which are potent anti-inflammatory compounds that reduce redness and itching.
- Barrier Protection: Forms a protective film that locks in moisture and shields the skin from environmental stressors.
Aloe Barbadensis Leaf Extract HighProven
Listed as the second ingredient, indicating a high concentration. Aloe vera provides antioxidants, enzymes, and vitamins A and C with potent anti-inflammatory and hydrating properties.
- Hydration: Rich in polysaccharides that attract and retain moisture in the skin.
- Soothing: Calms irritated skin and supports wound healing, making it ideal for buffering retinol side effects.
Phaseolus Radiatus (Mung Bean) Seed Extract Low-MidPromising
Extracted from mung beans, this ingredient is rich in vitamins, minerals, proteins, and antioxidants. It supports skin elasticity and provides nourishment to complement the anti-aging action of retinol.
- Antioxidant: Contains flavonoids that protect skin cells from free radical damage and environmental stress.
- Nourishing: Rich in amino acids and vitamins that support healthy skin cell function.
Allantoin LowProven
A gentle, well-established soothing ingredient that promotes cell regeneration, moisturizes, and helps heal minor skin irritation. Found naturally in comfrey root.
- Cell Renewal: Promotes keratinocyte proliferation for smoother, healthier-looking skin.
- Soothing: Calms redness and irritation, providing a buffer against retinol-related dryness.

Where it fits in your routine
ROUTINEUse in your PM routine only. Apply after toner and before moisturizer on clean, dry skin. Follow with SPF 30+ the next morning. Do not mix with AHA/BHA or benzoyl peroxide in the same routine.
How to use
HOW TO USECleanse & Dry
Wash your face with a gentle cleanser and pat dry completely. Retinol is best applied to dry skin to minimize irritation.
Apply 3-4 Drops
Dispense 3-4 drops onto your fingertips. Gently press and spread the serum across your face, avoiding the eye area and lips.
Wait 1-2 Minutes
Allow the serum to absorb fully before applying the next step. The lightweight, watery texture absorbs quickly.
Moisturize
Follow with your favorite moisturizer to lock in hydration and create a protective barrier over the retinol layer.
Start Slow & Build Up
Begin with 1-2 nights per week for the first 2 weeks. Gradually increase to every other night, then nightly as your skin builds tolerance.
Who is it for?
WHOPerfect for you if:
- You are a first-time retinol user looking for a gentle introduction
- You have sensitive skin that reacts to stronger retinoids
- You want to address early signs of aging (fine lines, dullness)
- You struggle with dark spots, uneven tone, or hyperpigmentation
- You want a clean, minimal formula free from common irritants
- You have oily or acne-prone skin and need a lightweight, oil-free serum
- You have fungal acne and need a Malassezia-safe retinol option
Consider alternatives if:
- You are pregnant or breastfeeding (try bakuchiol instead)
- You are an experienced retinol user who needs higher concentrations (0.5-1%)
- You need deep wrinkle correction (prescription tretinoin may be better)
- You want a retinol with added hyaluronic acid for extra hydration
- You have extremely dry skin and need a richer, cream-based retinol formula
Skin type compatibility
SKIN TYPESWatery, oil-free formula absorbs instantly without adding shine. Niacinamide helps regulate sebum for a matte, balanced look.
Glycerin and aloe provide hydration, but dry skin types will need a rich moisturizer on top. Does not contain hyaluronic acid or oils.
Lightweight texture balances well across oily and dry zones. Won't overwhelm the T-zone or leave cheeks feeling stripped.
Encapsulated retinol, oat extract, allantoin, and aloe soothe and protect. Fragrance-free and allergen-free. Patch test first and start slowly.
Non-comedogenic (1/5), oil-free, silicone-free, and fungal acne safe. Retinol unclogs pores and niacinamide controls oil production.

Frequently asked questions
FAQNo. This serum contains retinol (Vitamin A), which is not recommended during pregnancy or breastfeeding. Retinoids are classified as a pregnancy risk and may cause birth defects. If you are pregnant, trying to conceive, or breastfeeding, consult your doctor and consider switching to bakuchiol-based alternatives, which offer similar benefits without the retinoid risk.
Yes! This serum is fungal acne safe. It does not contain any of the ingredients known to feed Malassezia yeast, including ferments, fatty acids, fatty acid esters, polysorbates, or oils. This is verified by both SkinSort and INCIDecoder databases. It is also reef safe.
This product already contains 0.3% retinol, so do not layer additional retinol on top of it. You can use vitamin C in the morning and this retinol at night, but avoid combining them in the same application. For AHA/BHA exfoliants, alternate nights rather than using them together. Combining retinol with AHAs, BHAs, or benzoyl peroxide in the same routine can cause excessive dryness and irritation.
This serum is excellent for oily, combination, and acne-prone skin thanks to its watery, oil-free texture and non-comedogenic formula. It also works well for sensitive skin due to the encapsulated retinol delivery and soothing ingredients like oat extract, allantoin, and aloe vera. Dry skin types can use it but should pair it with a rich moisturizer. It is especially ideal for retinol beginners.
Most users notice smoother texture within the first 2 weeks. Brightening and improvement in skin tone typically appear around weeks 3-4. Significant results for dark spots, fine lines, and overall firmness are usually visible by weeks 8-12 with consistent nightly use. Retinol benefits are cumulative, so patience and consistency are key.
Apply this retinol serum in your PM (nighttime) routine only, after cleansing and toning but before your moisturizer. The order is: Cleanser, Toner, This Serum, Moisturizer, and optional Face Oil on top. In the morning, always apply SPF 30+ sunscreen. Do not combine with other active serums like AHA/BHA in the same routine.
This serum has a comedogenic rating of 1 out of 5, meaning it is very unlikely to clog pores. The formula is completely oil-free, silicone-free, and contains no known pore-clogging ingredients. It is safe for acne-prone skin and is also fungal acne (malassezia) safe, making it one of the cleanest retinol options available.
The recommended Period After Opening (PAO) is 6 months. Retinol is sensitive to air, light, and heat, and will gradually lose potency over time. Store the bottle in a cool, dark place (or in the fridge) and make sure to close the dropper cap tightly after each use. If the serum changes color to a deep yellow or brown, it may have oxidized and should be replaced.
Verdict: The Glow Glass Gentle 0.3% Retinol Serum is an outstanding entry-level retinol that punches above its price. Its nano-encapsulated retinol delivery system, combined with soothing oat extract and a multi-brightening complex of niacinamide and alpha-arbutin, makes it a thoughtfully formulated product for those new to retinol or with sensitive skin. The ultra-clean, 16-ingredient formula is fragrance-free, oil-free, fungal acne safe, and non-comedogenic — a rare combination in the retinol serum category. The main drawbacks are its limited availability outside the Philippines, the small 30ml bottle size, and its 0.3% concentration which may not satisfy experienced retinol users seeking stronger results. For beginners and those who value a clean, minimal formula, this is an exceptional value at ₱349.
Product Overview
Quick product notes are a great way to check if a product is free from commonly avoided ingredients by skincare enthusiasts. These preferences come about for different reasons depending on the ingredient such as personal experiences, sensitivities, health preferences & etc.

Quick Product Notes
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 «promises» 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.
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
Notable Effects & Ingredients
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!
Ingredients Related to Skin Types
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.
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.
