Without washing, your skin would be covered with a thick layer of dirt and grime which make it difficult for other products to penetrate the skin properly.Maintaining clear skin: Excessive dirt build up on the surface can cause blockages of the follicle, trapping sebum, sweat and dead skin cells. The lack of sebum on the skins surface allows bacteria to penetrate the follicle causing inflammation. The final result is acne.Some other benefits of cleansing: Regular cleansing is essential to keeping your skin looking radiant and healthy.Cleansing helps anti-aging products and treatments work properly.Cleansing helps maintain proper pore size.Cleansing encourages proper skin hydration and prevents the production of excess oils.
