Corthe Dermo Bright C Ampoule

If you love the KrX Vitamin Serum but want a higher potency Vitamin C, The Corthe Dermo Bright C Ampoule is a targeted brightening serum designed to visibly soften hyperpigmentation while supporting healthier, more resilient skin.

Powered by natural skin brighteners, antioxidant-rich plant extracts, and barrier-strengthening nutrients, it works beneath the surface to help reverse the effects of free radical damage and restore clarity over time.

This formula pairs Niacinamide with Ascorbyl Glucoside—a gentle, stable vitamin C derivative—alongside soothing botanicals like mallow, peppermint, and lemon balm to calm, refine, and brighten without irritation. A blend of herbal extracts and hydrating humectants reinforces the skin barrier, leaving the complexion balanced, luminous, and more even with consistent use.

Ascorbyl glucoside works by inhibiting tyrosinase activity — the enzyme responsible for melanin production — thereby reducing dark spots and promoting a more even complexion, while also offering antioxidant protection and supporting collagen synthesis. 

What makes the formula particularly smart is the combination of three pigmentation pathways working simultaneously: niacinamide inhibits the transfer of melanosomes to the skin's surface, ascorbyl glucoside inhibits tyrosinase to reduce melanin formation, and Resmelin also inhibits tyrosinase through a gentler botanical mechanism. 

It's a stable, gentle, well-designed Vitamin C for daily use — especially strong for hyperpigmentation and post-inflammatory discoloration. If you are expecting the same intensity as a high-dose L-ascorbic acid product please note that results are gradual (4–8 weeks realistically), but without the oxidation, instability, or irritation that comes with pure Vitamin C.
