Key Ingredients

Here’s what powers the Cos De BAHA Salicylic Acid BHA 4% Serum 30ml (S4):

Salicylic Acid (BHA)

Salicylic Acid is an oil-soluble exfoliant that works inside pores to remove buildup and excess sebum. It’s widely used for blackheads, acne, and rough texture concerns.

Niacinamide (Vitamin B3)

Niacinamide helps support balanced oil production while improving the appearance of enlarged pores and uneven skin tone. It also helps the skin feel calmer and more balanced.

Panthenol (Pro-Vitamin B5)

Panthenol helps maintain moisture levels and reduce feelings of dryness after exfoliation. It supports a healthier skin barrier over time.

Sodium Hyaluronate

This form of hyaluronic acid helps attract hydration to the skin and prevents tightness. It keeps the serum feeling comfortable despite the active exfoliation.

Aloe Barbadensis Leaf Extract (Aloe Vera)

Aloe Vera helps soothe visible irritation and provides lightweight hydration. It works especially well alongside stronger active ingredients like BHA.

Allantoin

Allantoin helps calm the skin and soften rough areas. It supports smoother-feeling skin after regular exfoliation.
