Get the appWhat it does
A prodrug form of vitamin C that penetrates the skin barrier more easily than pure ascorbic acid due to its smaller molecular size and increased stability. Once absorbed, enzymes in the skin convert it to free ascorbic acid, which functions as an antioxidant. It is gentler and less irritating than L-ascorbic acid while offering similar benefits.
Benefits
- Brightens skin and reduces dark spots with lower irritation risk
- Antioxidant protection against environmental stressors and free radicals
- Supports collagen synthesis for improved skin firmness and texture
- More stable than L-ascorbic acid; longer shelf life in formulas
Who it suits
- Sensitive skin
- Acne-prone skin
- Dull or hyperpigmented skin
- Those seeking gentler vitamin C alternatives
How to use
Apply to clean, dry skin in serums or creams, typically 10–20% concentration. Use morning or evening; follow with moisturizer and sunscreen.
Pairs well with
Hyaluronic acid, Niacinamide, Vitamin E, Peptides
Be careful pairing with
High-pH products (optimal pH 3.5–5.5), Niacinamide in very high concentrations (though generally compatible)
Safety & cautions
Conversion to active ascorbic acid may be incomplete or slower in some individuals; effectiveness depends on skin pH and enzymatic activity. Use sunscreen during the day as vitamin C can increase photosensitivity.
