Cos De BAHA Premium Azelaic Acid 10% Serum is a targeted treatment for blemish-prone, redness-prone, and oily skin types. This lightweight, water-like serum harnesses the power of 10% azelaic acid, a naturally occurring compound known for its ability to soothe redness, reduce the appearance of blemishes, and refine pores. Enriched with niacinamide (vitamin B3) and panthenol (pro-vitamin B5), it supports the skin barrier while calming irritation. The aloe vera-based formula ensures a non-greasy, fast-absorbing texture that layers beautifully under moisturizer or sunscreen. Suitable for daily use, this serum is a staple in Korean skincare routines for those seeking a clearer, more even complexion.
After cleansing and toning, apply a few drops of the serum to your face and neck. Gently pat until fully absorbed. Follow with a moisturizer and sunscreen during the day. Use once or twice daily as part of your skincare routine. Avoid contact with eyes. If irritation occurs, reduce frequency or discontinue use.
This serum is designed for individuals with blemish-prone, redness-prone, or oily skin. It is also beneficial for those dealing with uneven skin tone, enlarged pores, or mild rosacea. Suitable for all skin types, including sensitive skin, due to its gentle, aloe-based formulation.
Cos De BAHA is a trusted Korean skincare brand known for its high-quality, scientifically formulated products. This serum combines multiple active ingredients in a single, affordable bottle, offering a comprehensive solution for common skin concerns. The lightweight texture ensures it won't weigh down oily skin, while the soothing ingredients make it suitable for daily use. Backed by positive customer reviews and a commitment to cruelty-free practices, this serum is a reliable choice for anyone seeking effective, gentle skincare.
