The ordinary Salicylic acid 2% solution is an effective exfoliant. Being a beta hydroxy acid means it penetrates deeper into the layers of the skin dissolving excess dirt and sebum in the pores. It works to improve texture and clarity of the skin over time. It can also be used as a spot treatment on pimples as well as a regular treatment to keep skin clean and clear.
Use sunscreen during the day (even in winter) if using this product as it can increase sensitivity to the sun and cause further blemishing without sun protection.
