Now the environmental pollution is serious, and the car exhaust, mobile phone and computer radiation make our skin in an unstable state. Therefore, the ability of skin to resist and protect is very important. There are about five to eight layers of cuticle on the surface of human body. If it is less than four layers, the stratum corneum is thin. In this case, the skin is easily allergic to the product. So exfoliating shower gel can't be washed every day. In this case, the lethality of the skin is too strong, the self-growth speed of the skin is not fast enough, and the skin is easily injured. Usually it can be used once or twice a week. The best time is better; If it is a face, it is recommended to exfoliate once a month. Do not use exfoliating facial cleanser. After long-term use, the horny layer of the face will become thinner and more acidic. In this case, your facial allergy rate will be very high in the future.
