Cosrx AHA BHA Clarifying Treatment Toner

AHA stands for alpha hydroxy acid. AHAs are water-soluble acids often made from sugary fruits. They help eliminate dead skin cells on the skin surface by cleaving the retained bonds between dead skin cells, and promote new skin cells production, making your skin smoother and more evenly pigmented. Because AHAs stimulate collagen production, it can also help reduce wrinkles and fine lines.

BHA stands for beta hydroxy acids. The most common form of BHA is Salicylic acid (SA), a fat-soluble substance. Unlike AHAs, BHAs can penetrate pores to remove excess sebum and fight bacteria so that they can unclog pores, diminishing whiteheads, blackheads, and acne.

As we all know, the skin has an automatic mechanism of excreting billions of cells every day. However, due to various factors, such as frequent exposure to environmental pollution or chronic stress, this mechanism is weakened and slowed down. If you don’t want a dull and acne-prone skin, exfoliating is a must.

A toner offers extra help for exfoliating your skin. In cleansing and exfoliating, you are removing the oil, dirt, and dead skin cells off your face. Initially, after washing your face, you will get a dry surface unto your skin. This is where the toner comes in and hydrates your skin.
