A good skin care regimen will provide cumulative effects when it comes to achieving and maintaining beautiful skin. These simple, yet essential steps to follow are cleansing, exfoliating, balancing, and moisturizing - with each step providing added benefits to the previous step.
Q - Why is it important for the skin to be at its natural acidic balance? What is the "acid mantle?"
A - The acid mantle is a fluid that bathes the top layer of the skin. It is composed of fresh sebum, sweat, and other cell secretions. It is believed that the acid mantle acts as a natural defense barrier against skin infections. The skin surface has a normal pH range of 4.5 - 6.0. Raising the pH of the skin through cleansing alters the skin's natural balance of skin flora and may be drying or irritating with continued use. Skin will return to its natural pH over time, (in most people this happens within 2 to 3 hours, but in some it may be up to 24 hours). Using pH Balance can return the skin's natural pH immediately, and lessen the normal consequences of cleansing.＜本文发表于: 相约加拿大:枫下论坛 www.rolia.net/f ＞
