Cosrx AHA 7 Whitehead Power Liquid Review:
The term ‘chemical exfoliation’ may sound a bit scary (well, to me anyway!), but it is actually gentler and more effective than physical exfoliation. Physical exfoliation works to get rid of the dead skin just on the surface, and sometimes can be a bit harsh for the skin. When it is harsh it can cause micro-tear, and that is pretty much an invitation to bacteria to come and have an acne party on your face. While chemical exfoliation on the other hand works deeper to loosen up dead skin cells and sebum and at the same time promotes healthy cell regeneration.
