15% Vitamin C And EGF Serum
A gentle yet effective brightening serum combining 15% stabilized Vitamin C (Ascorbyl Glucoside) with plant-derived Epidermal Growth Factor (EGF) to target hyperpigmentation, dullness, and signs of aging while supporting skin regeneration and elasticity.
✨ Texture & Feel
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.
🛡️ Safety & Compatibility
Contains no retinoids, salicylic acid, or other pregnancy-restricted ingredients. Officially confirmed safe by the brand.
Contains PEG-40 Hydrogenated Castor Oil which may potentially feed Malassezia yeast. Patch test if you have fungal acne concerns.
No pore-clogging ingredients detected. Comedogenic rating 0/5 - suitable for acne-prone skin.
Neutral pH (6.8-7.2) and stable Vitamin C form means significantly less irritation than L-Ascorbic Acid serums.
Avoid using in the same routine as Retinol, AHAs (Glycolic, Lactic), BHAs (Salicylic), or Niacinamide to prevent irritation.
EGF is naturally found in the body. The 1% concentration used is tiny and considered safe for topical skincare use.
🔬 Ingredient Breakdown
🍊 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
🧬 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)
🌿 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

📝 How to Use
Cleanse & Prep
Start with clean, damp skin. Can be used after toner or hyaluronic acid if desired.

👤 Who Is It For?
✅ Perfect for you if:
- You have hyperpigmentation, dark spots, or uneven skin tone
- You're new to Vitamin C and want a gentle introduction
- Your skin is sensitive and can't tolerate L-Ascorbic Acid
- You want anti-aging benefits without irritation
- You're pregnant or breastfeeding and need safe actives
- You prefer simple, no-frills formulas
- You want budget-friendly access to EGF technology
❌ Consider alternatives if:
- You need maximum potency from L-Ascorbic Acid
- You have active fungal acne (contains PEG-40)
- You experience pilling under makeup/SPF
- You want added hydrating ingredients like Hyaluronic Acid
- You prefer vitamin C combined with Ferulic Acid and Vitamin E
- You need dramatic, fast results
🎯 Skin Type Compatibility
Lightweight, watery texture absorbs quickly without adding shine or greasiness. Non-comedogenic formula won't clog pores.
Works well but doesn't provide significant hydration. Layer with hyaluronic acid and rich moisturizer for best results.
Balances well across different face zones. Light enough for oily areas, compatible with adding moisture to dry areas.
Gentler than L-Ascorbic Acid with neutral pH. Fragrance-free formula minimizes irritation risk. Great for vitamin C beginners.
Non-comedogenic with 0/5 rating. However, those with fungal acne should patch test due to PEG-40 content.

- Lightweight, fast-absorbing texture
- Clean formula - vegan, cruelty-free, fragrance-free

❓ Frequently Asked Questions
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.
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.
