COSRX The RX Brightening Booster Set

Buying three COSRX actives separately adds up quickly, which is what makes this set worth a look. The RX Brightening Booster Set brings together three full sizes: the Vitamin C 23 Serum, the 6 Peptide Skin Booster Serum and the Advanced Snail 92 All in One Cream.

Each piece does a different job. The Vitamin C 23 Serum is the brand's high-strength option at 23% pure ascorbic acid, with glutathione and vitamin E alongside it. The 6 Peptide Skin Booster is a lightweight, toner-like serum with six peptides, willow bark water and apple fruit water, designed as a first step that layers under anything. The Advanced Snail 92 All in One Cream finishes the routine with snail secretion filtrate leading the ingredient list. Used in order they cover a full serum-to-cream routine from one brand.

This suits normal, combination and dull-looking skin, particularly anyone already comfortable with actives. Because of the high vitamin C concentration, introduce it gradually and pair the routine with daily sunscreen.
