First, do you know that the skin sheds off thousands of dead skin cells every minute? Dead skin cells can shed through the normal daily activities we engage in like standing, pulling off our clothes, walking, etc.
Exfoliation is the process through which we get rid of these dead cells from the upper layer of the skin, even faster.
There are two basic ways to exfoliate. These include the Mechanical method and the Chemical method.
Mechanical method involves using a tool, most times objects with slightly rough surfaces to slough off dead cells from the surface of the skin.
This can include sponge, washcloth, face scrub, etc.
Chemical method involves the use of chemicals to get rid of dead skin cells.
AHA ( Alpha hydroxy acid) : This is derived from sugary fruits. They work mostly by working on the top layer of the skin and gently peels off the dead skin cells.
BHA ( Beta hydroxy acid) : BHAs are oil soluble. This makes them go deep into the skin pores. They have the ability to decongest the pores, while simultaneously fighting the bacteria that can cause acne.
Now, no one wants all these bad guys on the skin, hence exfoliation is important.
Exfoliation is advisably done twice a week, as daily exfoliation can damage the skin, cause irritation, breakouts and make the skin too sensitive to touch. This defeats the essence of Exfoliation.
Bottom line, talk to your dermatologist, know your skin type and get the right product for your skin.
