KOYO Luminous Glow Vitamin C Serum
KOYO Luminous Glow Vitamin C Serum is a brightening treatment designed for skin that looks dull, uneven, or marked by post-acne pigmentation. It is formulated to help revive radiance, improve the appearance of uneven skin tone, and promote a clearer, more luminous complexion with regular use.
The formula is built around 10% Glyceryl Ascorbate, supported by Ascorbyl Glucoside for added brightening benefit. Alpha-Arbutin helps target the appearance of post-acne marks and uneven tone, while Ferulic Acid supports the overall antioxidant profile of the serum. A touch of Salicylic Acid helps refine the look of congestion and texture, making this serum especially useful for those who want brightness without ignoring blemish-prone concerns. Panthenol, Allantoin, and Sodium Hyaluronate help keep the formula more skin-friendly by adding hydration and comfort.
This is the kind of serum that works well for anyone looking to bring life back to tired, lacklustre skin while also targeting post-breakout marks and rough texture. With continued use, skin looks fresher, clearer, smoother, and more radiant.
