Brightening Power

15% Ascorbyl Glucoside converts to pure Vitamin C on skin to target dark spots, hyperpigmentation, and uneven skin tone.

Skin Regeneration

Plant-derived EGF (Epitensive™) stimulates skin cell renewal, supporting natural collagen and elastin production for firmer skin.

Antioxidant Protection

Shields skin from environmental stressors including UV damage, pollution, and free radicals that accelerate aging.

Gentle Formula

Stable Vitamin C derivative at neutral pH makes this ideal for sensitive skin and Vitamin C beginners without harsh irritation.

02

Safety & compatibility

SAFE
Pregnancy & Breastfeeding Safe

Contains no retinoids, salicylic acid, or other pregnancy-restricted ingredients. Officially confirmed safe by the brand.

Fungal Acne - Use with Caution

Contains PEG-40 Hydrogenated Castor Oil which may potentially feed Malassezia yeast. Patch test if you have fungal acne concerns.

Non-Comedogenic

No pore-clogging ingredients detected. Comedogenic rating 0/5 - suitable for acne-prone skin.

Sensitive Skin Friendly

Neutral pH (6.8-7.2) and stable Vitamin C form means significantly less irritation than L-Ascorbic Acid serums.

Do Not Mix with Certain Actives

Avoid using in the same routine as Retinol, AHAs (Glycolic, Lactic), BHAs (Salicylic), or Niacinamide to prevent irritation.

EGF Safety Note

EGF is naturally found in the body. The 1% concentration used is tiny and considered safe for topical skincare use.

Ingredient breakdown

INGREDIENTS

Ascorbyl Glucoside 15%Proven

A stable, water-soluble Vitamin C derivative that converts to pure L-Ascorbic Acid when absorbed by skin. Provides brightening, antioxidant, and collagen-boosting benefits without the instability issues of pure Vitamin C.

  • Stability: Remains effective at neutral pH, unlike L-Ascorbic Acid which requires low pH
  • Conversion: Enzymatically converted to active Vitamin C in the skin
  • Benefits: Brightens, evens tone, provides antioxidant protection, supports collagen synthesis
Excellent choice for Vitamin C beginners or those with sensitive skin who can't tolerate L-Ascorbic Acid.

Oligopeptide-1 (EGF) 1%Promising

Epitensive™ is a plant-derived Epidermal Growth Factor - a signaling peptide that helps regulate cellular growth, proliferation, and differentiation. Supports skin renewal and regeneration.

  • Function: Stimulates skin cells to regenerate for rejuvenated, youthful appearance
  • Collagen Support: Helps support natural collagen and elastin within the skin's matrix
  • Origin: Plant-based peptide (vegan-friendly)
Wait 10 minutes after application before layering other products to allow EGF to work optimally.

Phytic Acid <1%Supporting

A mild AHA derived from rice bran that provides gentle exfoliation and antioxidant benefits. Also acts as a chelating agent to improve formula stability.

  • Exfoliation: Gentle exfoliating properties to enhance skin texture
  • Antioxidant: Additional free radical protection
  • Stabilizer: Helps maintain product efficacy

Skin type compatibility

SKIN TYPES
Oily Skin
Excellent

Lightweight, watery texture absorbs quickly without adding shine or greasiness. Non-comedogenic formula won't clog pores.

Dry Skin
Good

Works well but doesn't provide significant hydration. Layer with hyaluronic acid and rich moisturizer for best results.

Combination Skin
Excellent

Balances well across different face zones. Light enough for oily areas, compatible with adding moisture to dry areas.

Sensitive Skin
Excellent

Gentler than L-Ascorbic Acid with neutral pH. Fragrance-free formula minimizes irritation risk. Great for vitamin C beginners.

Acne-Prone Skin
Good

Non-comedogenic with 0/5 rating. However, those with fungal acne should patch test due to PEG-40 content.

Frequently asked questions

FAQ

Yes, this serum is confirmed pregnancy and breastfeeding safe by the brand. It contains no retinoids, salicylic acid, hydroquinone, or other pregnancy-restricted ingredients. The stable Vitamin C derivative (Ascorbyl Glucoside) and plant-based EGF are both considered safe during pregnancy and nursing.

Use with caution if you have fungal acne. This serum contains PEG-40 Hydrogenated Castor Oil, which is flagged as potentially feeding Malassezia yeast that causes fungal acne. While many users with fungal acne report no issues, we recommend patch testing first if you're prone to this condition.

Do not use in the same routine as Retinol, AHAs (Glycolic, Lactic, Mandelic Acid), BHAs (Salicylic Acid), or PHAs. These combinations can cause irritation. Use this Vitamin C serum in your AM routine and save Retinol or acid exfoliants for PM. Also avoid layering with Niacinamide at the same time.

This serum works well for all skin types but is especially excellent for sensitive skin and Vitamin C beginners. The stable, neutral-pH formula is much gentler than L-Ascorbic Acid serums. Oily and combination skin types love the lightweight, non-greasy texture. Dry skin types should layer with additional hydrating products.

Most users notice initial brightening and glow within 1-2 weeks. Significant improvements in hyperpigmentation, dark spots, and skin tone typically take 4-6 weeks of consistent daily use. The EGF benefits for firmness and elasticity may take 6+ weeks to become noticeable. Consistency is key - more product won't speed up results.

Apply after cleansing (and toner/hyaluronic acid if using) on damp skin. Wait 10 minutes before applying subsequent products to allow EGF to work optimally. Follow with moisturizer and always SPF in the morning. The brand recommends AM use to maximize antioxidant protection against daily environmental stressors.

No, this serum has a comedogenic rating of 0/5. No pore-clogging ingredients were detected in the formula. It's suitable for acne-prone skin and should not cause breakouts. However, always patch test when trying new products, especially if your skin is reactive.

The PAO (Period After Opening) is 12 months. The stable Ascorbyl Glucoside form of Vitamin C is much more resistant to oxidation than L-Ascorbic Acid serums. Store in a cool, dry place away from direct sunlight. A light yellow tint is normal and doesn't indicate spoilage - it comes from the natural ingredients.

— Skincarisma verdict
4.3 / 5 ★★★★☆

Verdict: The Inkey List 15% Vitamin C and EGF Serum is an excellent entry-level brightening serum that delivers gentle yet effective results without the irritation of traditional Vitamin C serums. The combination of stable Ascorbyl Glucoside with plant-derived EGF peptide offers a unique dual-action approach to brightening and skin regeneration at an accessible price point. Ideal for sensitive skin, Vitamin C beginners, and those seeking pregnancy-safe actives. While not as potent as pure L-Ascorbic Acid formulas, the trade-off in gentleness and stability makes this a reliable daily driver for gradual, consistent improvement in skin radiance and tone.

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 «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.

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

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.

muscle Pro Tip Alert!

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.
