Salicylic Acid Bha 4% Serum - 30ml
COS DE BAHA - Salicylic Acid Bha 4% Serum - 30ml is a K-beauty face serum centered on salicylic acid BHA. The product title confirms the 4% BHA positioning, so it is best understood as a targeted active serum rather than a general hydrating essence.
Why It Stands Out
The formula focus is unusually clear from the name, which helps shoppers compare it with gentler daily serums. For oily or congestion-prone routines, a named BHA step can be easier to schedule than using multiple exfoliating products at once.
Best For
Best for users managing rough texture, visible pore buildup, or excess-oil routines. It is a better match for experienced active users than for someone wanting only a basic moisturizer replacement.
How to Use
Apply a small amount after cleansing, preferably at night at first. Follow with moisturizer, avoid stacking with several exfoliating acids in the same routine, and use sunscreen during the day.
Benefits
- Salicylic acid BHA focus is verified in the title.
- Supports a more refined-feeling texture routine.
- 30ml serum format is easy to dose gradually.
- Fits targeted care for oily or clogged-looking areas.
Good to Know
Start slowly and pause if the skin feels over-exfoliated. Do not use around the eye area, and patch test before adding it to a full routine.
