Cos De BAHA NZ Serum is a powerful formulation designed to address multiple skin concerns, especially for those with oily and acne-prone skin. With a potent 20% concentration of Niacinamide, this serum significantly strengthens the skin barrier, improves overall skin tone, controls sebum, and offers anti-inflammatory and brightening benefits. Zinc PCA at 4% further aids in sebum regulation and helps to reduce acne, making the skin clearer and more balanced. Sodium Hyaluronate ensures that the skin remains deeply hydrated, enhancing elasticity and plumpness. Additionally, (Beta) Arbutin works to reduce hyperpigmentation and brighten the complexion, resulting in a more even-toned and radiant appearance.
