Get the appWhat it does
Vitamin C neutralizes free radicals and stabilizes collagen synthesis, reducing fine lines and discoloration. It brightens the complexion by inhibiting melanin production. When used before sun protection, it enhances photoprotection and helps prevent UV-induced oxidative stress.
Benefits
- Brightens dull skin and fades hyperpigmentation over 4-12 weeks
- Supports collagen production, improving firmness and elasticity
- Provides antioxidant defense against environmental damage
- Enhances effectiveness of SPF when used together
- Reduces appearance of fine lines and uneven tone
Who it suits
- All skin types, especially dull, aging, or hyperpigmented skin
- Sun-exposed or photo-damaged skin
- Acne-prone skin needing brightening without irritation
How to use
Apply a few drops of vitamin C serum to clean, dry skin in the morning before moisturizer and SPF. Use 3-5x weekly initially, building to daily once skin adapts; discontinue if excessive irritation occurs.
Pairs well with
Vitamin E (synergistic antioxidant protection), Ferulic acid (stabilizes and enhances C efficacy), Sunscreen (maximizes photoprotection), Hyaluronic acid (adds hydration without reducing efficacy)
Be careful pairing with
Niacinamide (can cause flushing; not chemically unstable but user tolerance may suffer), Retinol (both are potent; layer separately or use in AM/PM rotation)
Safety & cautions
L-Ascorbic Acid is unstable and requires low pH (2.5-3.5), which may irritate sensitive skin; stabilized forms are gentler. Oxidizes when exposed to air or light, so proper packaging is essential for efficacy.
