โจ Texture & Feel
Brightening Powerhouse
10% L-Ascorbic Acid combined with Alpha-Arbutin works to visibly reduce dark spots and even out skin tone for a luminous complexion.
Antioxidant Triple Threat
The Vitamin C + Vitamin E + Ferulic Acid trio provides synergistic antioxidant protection against UV-induced free radical damage and photoaging.
Collagen Support
L-Ascorbic Acid at 10% concentration is clinically proven to stimulate collagen synthesis, helping firm and plump the skin over time.
Clean & Minimal Formula
Only 18 ingredients with no fragrance, parabens, silicones, oils, or sulfates. Includes soothing chamomile water and aloe vera for calming hydration.
๐ก๏ธ Safety & Compatibility
Contains no retinoids, salicylic acid, hydroquinone, or chemical sunscreens. Vitamin C, Vitamin E, ferulic acid, and alpha-arbutin are all considered safe during pregnancy and breastfeeding.
Contains Steareth-21 (a PEG-based emulsifier) and Butylene Glycol, which some fungal-acne-prone individuals may want to avoid. Most other ingredients are FA-friendly, but patch testing is recommended.
Oil-free, silicone-free formula with no known pore-clogging ingredients. Very low risk of causing breakouts or clogged pores.
L-Ascorbic Acid at 10% with a low pH may cause mild tingling or irritation on very sensitive or reactive skin. Start with every other day and build up tolerance.
No animal-derived ingredients and not tested on animals.
Vitamin C boosts photoprotection but does not replace sunscreen. Apply SPF 30+ daily when using this serum to prevent further pigmentation and maximize brightening results.
๐ฌ Ingredient Breakdown
๐ L-Ascorbic Acid (Vitamin C) 10% Proven
The gold standard of topical Vitamin C. This pure, biologically active form is clinically proven to brighten skin, fade hyperpigmentation, boost collagen production, and neutralize free radicals when formulated at the right pH and concentration.
- Proven Efficacy: Clinically effective at 5โ20% concentration for collagen synthesis and photoprotection.
- Brightening: Inhibits tyrosinase enzyme activity, reducing melanin production and fading dark spots.
- Synergy: When combined with Vitamin E and Ferulic Acid, photoprotection is doubled (Pinnell et al., 2005).
- pH Dependent: Requires a pH below 3.5 for optimal skin penetration and bioavailability.
๐พ Ferulic Acid ~0.5% Proven
A plant-derived antioxidant naturally found in rice bran, wheat, and oats. Its primary claim to fame is stabilizing Vitamin C while dramatically boosting the formula's photoprotective abilities.
- Stabilizer: Adding 0.5% Ferulic Acid to a Vitamin C + E formula stabilizes the unstable L-Ascorbic Acid.
- Doubles Protection: Landmark 2005 study showed it doubles the photoprotection of a C+E combination.
- UV Defense: Independently protects against UV-induced skin damage and can penetrate the skin effectively.
๐ฅ Tocopherol (Vitamin E) 1% Proven
A fat-soluble antioxidant that protects cell membranes from oxidative damage. Moisturizes the skin while working as a network antioxidant with Vitamin C โ each regenerates the other for longer-lasting protection.
- Network Antioxidant: Recycles oxidized Vitamin C back to its active form, extending protection.
- Barrier Support: Strengthens the skin's lipid barrier and reduces transepidermal water loss.
- Anti-inflammatory: Helps soothe irritation and reduce redness from UV exposure.
๐ Alpha-Arbutin <1% Promising
A biosynthetic skin-brightening agent derived from hydroquinone but significantly gentler. Works by inhibiting tyrosinase to reduce melanin production without the harsh side effects of hydroquinone.
- Brightening: Up to 10x more effective than beta-arbutin at inhibiting melanin synthesis.
- Gentle: Considered a safer alternative to hydroquinone with fewer side effects.
- Complementary: Enhances the brightening effects of Vitamin C when used together.
๐ผ Chamomile Flower Water Supporting
Chamomilla Recutita (German Chamomile) flower water provides gentle anti-inflammatory and antioxidant properties. Helps calm and soothe the skin, which is especially beneficial alongside the active Vitamin C.
- Soothing: Contains bisabolol and chamazulene compounds known for calming irritated skin.
- Antioxidant: Provides mild additional antioxidant support to complement the main actives.
๐ต Aloe Barbadensis Leaf Extract Supporting
A well-known botanical extract with moisturizing, emollient, and anti-inflammatory properties. Helps hydrate the skin and reduce potential irritation from the active vitamin C.
- Hydration: Provides lightweight moisture without clogging pores.
- Soothing: Clinically recognized for its wound-healing and anti-inflammatory benefits.

๐ Where It Fits in Your Routine
Apply after cleansing and toning on bare skin. Wait 1โ2 minutes before layering moisturizer. Always follow with SPF 30+ in the morning.
๐ How to Use
Cleanse & Prep
Start with clean, dry skin. Use a gentle cleanser and pat face dry. Optionally apply a hydrating toner and let it absorb.
Apply 2โ4 Drops
Dispense 2โ4 drops onto your fingertips. Gently press and pat the serum across your face and neck, avoiding the eye area.
Wait & Layer
Allow 1โ2 minutes for the serum to absorb fully before applying your moisturizer. A slight tingling is normal with Vitamin C.
Sunscreen (AM)
In the morning, always follow with a broad-spectrum SPF 30+ sunscreen. Vitamin C enhances sun protection but never replaces it.

โ Frequently Asked Questions
Yes. This serum contains no retinoids, salicylic acid, hydroquinone, or chemical sunscreens โ all of which are commonly flagged during pregnancy. The active ingredients (L-Ascorbic Acid, Tocopherol, Ferulic Acid, Alpha-Arbutin) are generally considered safe for use during pregnancy and breastfeeding. However, always consult your healthcare provider before adding new skincare products to your routine during pregnancy.
Use with caution. While most ingredients in this formula are fungal-acne-friendly, it contains Steareth-21, a PEG-based emulsifier that some fungal-acne-prone individuals prefer to avoid. Butylene Glycol is also present, which is generally well-tolerated but occasionally flagged. If you are strictly avoiding all potential FA triggers, you may want to patch test first or consider alternatives specifically formulated as malassezia-safe.
Yes, but with careful separation. L-Ascorbic Acid works best at a low pH, and using it simultaneously with other low-pH actives (AHA, BHA) or retinol can increase irritation risk. The safest approach is to use Vitamin C in the morning and retinol or exfoliating acids in the evening. If you want to use them in the same routine, apply the Vitamin C serum first, wait 15โ20 minutes, then apply your other actives. Avoid using with benzoyl peroxide, which can inactivate Vitamin C.
This serum works best for oily, combination, and normal skin types thanks to its lightweight, oil-free formula. Dry skin types can use it but should layer a richer moisturizer on top. Sensitive skin types should introduce it gradually (every other day) as the 10% L-Ascorbic Acid at low pH may cause initial tingling. It is also excellent for those with hyperpigmentation, dark spots, or dull skin regardless of skin type.
Most users notice an immediate glow and radiance boost after the first application. Visible brightening and dark spot reduction typically become noticeable within 2โ4 weeks of consistent daily use. Firming and anti-aging benefits from collagen stimulation generally take 6โ8 weeks to appear. For best results, use the serum consistently every morning (and optionally evening) for at least 8โ12 weeks.
Apply this serum as step 3 in your routine: after cleansing and toning, but before moisturizer and sunscreen. Apply 2โ4 drops to clean, dry skin and pat gently. Wait 1โ2 minutes for absorption, then follow with your moisturizer. In the morning, always finish with SPF 30+ sunscreen. The serum can be used both morning and evening.
This serum has a comedogenic rating of 1 out of 5, meaning it has a very low risk of clogging pores. The formula is oil-free, silicone-free, and contains no known comedogenic ingredients. It is suitable for acne-prone skin and should not cause breakouts for most people. If you have extremely reactive skin, a patch test on a small area is always recommended before full-face application.
The recommended Period After Opening (PAO) is 6 months. However, because L-Ascorbic Acid is inherently unstable, the serum may begin to oxidize sooner โ especially if not stored properly. Keep it in a cool, dark place with the cap tightly closed. Refrigeration can help extend its active life. If the serum turns dark yellow, orange, or brown, it has oxidized and should be discarded. A fresh serum should be clear to very pale yellow.
Verdict: The Glow Glass Vitamin C & E Ferulic Glow Booster Serum delivers the well-researched C+E+Ferulic antioxidant trio at an accessible price point, with the added bonus of Alpha-Arbutin for enhanced brightening. Its clean, 18-ingredient formula is free from fragrance, parabens, oils, and silicones โ making it a solid choice for those who want effective brightening without unnecessary additives. The 10% L-Ascorbic Acid concentration is gentler than many competitors, making it a good entry point for Vitamin C beginners. However, experienced users may prefer a higher-concentration option, and the inherent instability of L-Ascorbic Acid means careful storage is essential. An excellent value for the Filipino market and a worthy contender in the affordable CEF serum category.
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 ยซpromisesยป 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.
