Product Description

There's a reason why this serum is a best-seller... Every skincare enthusiast knows that a lot of top level skincare comes from South Korea. This serum is a must-have addition to your skincare routine, offering a comprehensive package when it comes to controlling acne and pigmentation. This serum contains 15% niacinamide, a ingredient known to control sebum production, inflammation and heals scars - in other words, this serum provides complete acne care. It also contains N-Acetylglucosamine (NAG), which combines seamlessly with niacinamide to target and reduce hyperpigmentation, while helping to balance overactive sebaceous glands, and clear blackheads, whiteheads, melasma, and blemishes. Enhanced with Allantoin, this powerful duo promotes collagen production, supporting skin regeneration for a smoother, more even complexion. What does it target? - Bumpy skin - Sebum oil - Pores - All stages of Acne - Even skin tone - Hyperpigmentation Ingredients: Water, Pentylene Glycol, Niacinamide(15%), Butylene Glycol, Acetyl Glucosamine, 1,2-Hexanediol, Zinc PCA, Trehalose, Xanthan Gum, Pullulan, Allantoin, Ethylhexylglycerin, Sodium Phytate, Citric Acid, Tocopherol
