The INKEY List Vitamin C + EGF Serum 1 Fl Oz — 15% Brightening Serum for Hyperpigmentation & Renewal

This serum blends a stable vitamin C derivative (ascorbyl glucoside) at 15% with a plant-based Epidermal Growth Factor (EGF) peptide to target uneven tone and signs of aging. The formula is fragrance-free, cruelty-free and designed to sit comfortably under other skincare steps. It converts on the skin to active vitamin C to help brighten, while EGF supports cellular renewal and the feel of elasticity for a more refreshed-looking complexion.

How quickly can I expect brighter, more even skin?

Results vary, but many users notice improved radiance within a few weeks of consistent use, with more visible reduction in hyperpigmentation over 6–12 weeks. Regular application AM (or PM if preferred) and sun protection improve outcomes.

• Apply a pea-sized amount daily on cleansed skin for steady improvements.
• Visible brightening often appears within weeks; tone correction takes longer.
• Daily SPF in the morning preserves results and prevents new discoloration.

Will this serum work with my other actives like retinol or exfoliating acids?

The serum is gentle enough for daily use, but pairing it with strong exfoliants or retinol requires spacing to avoid irritation. Use Vitamin C in the morning and retinol at night, or alternate nights if using both in the PM.

• Use AM for vitamin C to protect from environmental stressors; follow with SPF.
• If used at night, avoid combining on the same night as retinol or AHA/BHA exfoliators.
• Wait about 10 minutes before layering heavier creams so the EGF can act on skin surface.

Is this serum suitable for sensitive or acne-prone skin?

The formula is fragrance-free and designed for all skin types, including sensitive skin, but patch-testing is recommended. The stable vitamin C form (ascorbyl glucoside) is typically less irritating than L-ascorbic acid while still converting to active vitamin C on the skin.

• Fragrance-free and cruelty-free—minimal added irritants.
• Patch-test before full-face use if you have reactive skin.
• Reduce frequency if redness or stinging occurs, then gradually build tolerance.

How should I use the serum for best results?

Apply a pea-sized amount to face and neck after cleansing. If layering, wait ~10 minutes before applying heavier products so EGF and vitamin C can interact with the skin surface. Use daily; if only once daily, mornings are recommended for environmental protection benefits.

• Cleanse, then apply pea-sized serum to face and neck.
• Allow ~10 minutes before moisturizer or sunscreen to maximize activity.
• Use SPF each morning to maintain and protect brightening results.
