Description

Cos De BAHA Niacinamide 10% Serum(N) is a lightweight, fast-absorbing serum designed to bring oily and breakout-prone skin back into balance.

Key Ingredients
Here’s what powers the Cos De BAHA Niacinamide 10% Serum(N):

Niacinamide (Vitamin B3)
A well-researched ingredient known for regulating oil production, improving skin texture, and reducing the look of pores. It also supports a brighter, more even complexion with consistent use.

A hydration booster that attracts moisture into the skin. It keeps the formula lightweight while preventing dryness often associated with oil-control products.

Works to soothe and strengthen the skin barrier. It helps reduce redness and keeps skin feeling comfortable.

Allantoin
Known for its calming properties, allantoin supports skin healing and smoothness, making the serum gentle enough for regular use.

Provides antioxidant protection while helping to calm inflammation and balance oil levels.
