Product Information
The COSRX Refresh AHA BHA Vitamin C Booster Serum is a powerful, multi-functional daily treatment designed to deliver gentle chemical exfoliation and intense brightening, leaving the skin smoother, clearer, and more radiant. This serum combines three key active ingredients to address dullness, rough texture, excess oil, and hyperpigmentation.
???? The Triple Action Powerhouse
This serum is formulated with COSRX's Golden-Rx Complex (containing extracts from Gold Kiwis and Dragon Fruit) and a blend of chemical exfoliants and brighteners:
AHA (Glycolic Acid): A water-soluble Alpha Hydroxy Acid that works on the surface level of the skin. It helps to dissolve the bonds between dead skin cells, promoting gentle exfoliation and cell turnover to visibly smooth rough texture and boost overall skin radiance.
BHA (Betaine Salicylate): An oil-soluble Beta Hydroxy Acid that can penetrate deeper into the pores. It works to dissolve excess sebum, unclog pores, and address concerns like blackheads and whiteheads, making it excellent for controlling oil and managing acne-prone skin.
Vitamin C (Ascorbyl Glucoside): A stable and effective Vitamin C derivative and a potent antioxidant. It works to brighten the complexion, fade dark spots and hyperpigmentation, even out skin tone, and protect the skin against environmental stressors.
Niacinamide (2%): This form of Vitamin B3 is included to help strengthen the skin barrier, minimize the appearance of pores, regulate sebum production, and further enhance the brightening effects of Vitamin C.
???? Key Benefits & Results
Brighter, More Even Tone: Targets dullness and the appearance of dark spots, thanks to the combined power of Vitamin C and Niacinamide, revealing a luminous glow.
Smooths Skin Texture: The AHA and BHA components work in synergy to gently buff away dead skin cells, resulting in a significantly smoother and more refined skin surface.
Pore & Sebum Control: The BHA component helps to clear congested pores and manage excess oil, which is especially beneficial for those with combination or oily skin.
Hydrating & Soothing: The formula is balanced with hydrating and calming ingredients like Panthenol (Provitamin B5) and Sodium Hyaluronate to prevent dryness or irritation often associated with exfoliants, ensuring a comfortable, soft finish.
