Exfoliation aids in clearing clogged pores and getting rid of dead skin cells. Dr. Madhuri Agarwal, Founder and Medical Director of Yavana Aesthetic Clinic, says, “According to our usual skin cycle, we generally shed dead cells of old skin on a regular basis, but in case the skin functioning is not normal due to various reasons, such as an unhealthy lifestyle, continuous travel, pollution, changing climate, health problems, etc., the dead cells pile up on the surface of the skin and are not shed regularly.” Age is an important factor as well. She adds, “With age too, the cell turnover slows down and the dead cells are not shed properly. Due to this, the skin appears dull, dry and dark. A regular exfoliation routine helps remove the dead cells and makes the skin more healthy, hydrated and smooth. Hence it is essential to have exfoliation in a skincare regime.” She adds that in the winter season, the dead cell build up is even more as compared to the warmer months. Therefore, it is important to exfoliate regularly.
