1. Sensitive and fragile skin
The outermost cell layer of the skin is the stratum corneum. The role of the stratum corneum is to prevent the subcutaneous tissue from being invaded by foreign bacteria. The scrub has a strong cleaning ability. If used too frequently, the stratum corneum that protects the skin will be thinned, causing the skin to become dry. The barrier is damaged and the skin loses its protection, becoming sensitive and fragile.
2. Dry and dehydrated skin
The cuticle renewal cycle of the human epidermis is 28 days. Scrubs are used to help remove dead skin and oil from the skin. Using scrubs too frequently will only over-clean the moisture and oil on the surface of the skin, causing the skin to become drier with more washing. Tension easily. When skin is dry, itching and allergies can occur.
As for the question of how often to use scrub for the best effect, with age, changes in oil secretion and skin quality, individuals need to make adjustments according to their own skin conditions. Only using scrub correctly is beneficial to the skin.
