Glow-C Vitamin C 20% Serum

Glow-C Vitamin C 20% Serum was made for those who’ve tried every “brightening” serum—only to be left underwhelmed, irritated, or shiny. This powerhouse formula pairs a full-strength dose of 20% ethylated vitamin C with ferulic acid and skin-quenching glycerin to deliver visible results with none of the usual side effects.

Our stabilised vitamin C remains clear (never oxidising to brown) and glides on weightlessly, absorbing quickly without pilling or leaving behind a greasy film. Ferulic acid amplifies the antioxidant effects and helps defend against free radical damage, while glycerin locks in hydration for a smooth, radiant finish.

Whether you’re layering under SPF or targeting lingering dark spots, Glow-C delivers clinical performance in a gentle, non-irritating formula—no fragrance, no filler, just real results.

20% Ethylated Vitamin C (Ethyl Ascorbic Acid)

A potent, stabilised form of vitamin C that brightens skin, fades dark spots, and supports collagen production—without the irritation or instability of traditional ascorbic acid.

Ferulic Acid

A plant-derived antioxidant that enhances the effects of vitamin C while helping prevent and fade the appearance of dark spots and fine lines caused by oxidative stress.
