What is the best skin care routine to prevent aging?

Use sun protection every day all year round, protect against excess sun exposure, and exfoliate on a regular -- but not daily -- basis. Look for gentle products that do not strip away the outer layers, just gently remove the excess dead skin cells ready to slough off. The outer layers of skin cells are called the stratum corneum and studies show that this layer helps protect against sun damage and against excess water loss from the skin. When it is an even, smooth layer, the skin looks more radiant and younger. Retinoids, emollients, and gentle exfoliants help achieve this goal.
