<p data-start="163" data-end="1901">COSRX AHA BHA Vitamin C Booster Serum is a naturally derived, skin-revitalizing facial serum formulated to gently exfoliate, brighten, and rejuvenate the skin while delivering daily hydration and plumping care. Designed for all skin types, this lightweight watery serum works to improve dullness, uneven tone, and rough texture by combining mild exfoliating acids with antioxidant-rich fruit extracts and skin-strengthening ingredients. The formula features a unique blend of AHA and BHA to softly remove accumulated dead skin cells from the surface and within pores, helping refine skin texture, unclog congestion, and promote a smoother, clearer complexion without harsh irritation. Infused with a high concentration of fruit-based antioxidants, including 28.5% kiwi fruit extract and 28.5% dragon fruit extract, the serum delivers vibrant, refreshing energy to tired skin while supporting natural radiance and vitality. These fruit extracts help protect the skin from environmental stressors and contribute to a healthy, glowing appearance with continued use. Niacinamide at 2% further enhances the formula by improving skin tone balance, strengthening the moisture barrier, and supporting a smoother, more even-looking complexion. The fast-absorbing, non-sticky texture penetrates easily into the skin, making it ideal for daily use in both morning and evening routines. With regular application, the skin appears brighter, fresher, and more refined, with improved clarity and softness. Developed under COSRX clean beauty standards, this serum is hypoallergenic, dermatologist tested, cruelty-free, and free from parabens, sulfates, and phthalates, making it a gentle yet effective choice for daily skin renewal and radiance boosting.</p> <h3 data-start="1908" data-end="1926">Key Features</h3> <p data-start="1928" data-end="2476">This booster serum gently exfoliates the skin using AHA and BHA to improve texture and clarity while enhancing radiance with naturally sourced fruit extracts.
