Or the secret to perfect skin without makeup.

Assuming that no single product can meet all of the skin's needs effectively, one product should be used per need. This philosophy from Asia considers that you should put as many "layers" (= layer, in English) as necessary. The C.H.O layering now consists of 7 stages to be done every day.

Before you start, it's important to know your skin type to avoid blemishes. An online skin diagnosis is available here if you wish. Then don't go through 7 steps all at once, add one product at a time to your routine to give your skin time to get used to and react. The skin takes 21 days to renew itself, so give it time to get used to a new product.
