Exfoliation refers to the removal of dead skin cells, debris and excess oil from the surface of your skin to expose the healthier, newer layer of skin underneath.
Different skin types require different levels of care and exfoliation. For people with oily or acne prone skin exfoliation helps prevent a myriad of skin care issues such as acne, bumps and blemishes. It essentially removes the basic food source for bacteria and fungus that cause these issues.
For people with dry skin, removing dirt and dead skin cells also helps unclog your pores and expose the hair follicles on your face. This allows other skin care products such as moisturisers, shaving cream and even sun-screen do a better job at preventing fine lines and ingrown hairs and promoting even skin tones.
