The acid mantle of skin varies between 4.5-5.5. When it differs from this range, our skin loses moisture and so, the tendency of generating infections increases. It is essential to avoid damaging it in order to slow down the skin aging process. A 4.3 pH promotes natural exfoliation, cellular regeneration and protection against bacteria. This is recommended for oily skin types as they are more alkaline and need to increase the acidity to prevent infections, acne and sebum excess. Other active ingredients like the ones used in the Micelar Water, promote the balance of the pH.
