Anti-aging skin care should start in your 20s, when your skin cells are regenerating at an optimal rate. As you enter your 30s, your anti-aging skin care routine becomes even more important. You may begin to notice that your skin feels drier, and doesn’t quite have that same glow it did when you were younger. That’s because changes in your body are reflected in your skin and, as you approach your 40s, anti-aging skin care becomes even more important. In your 50s, your anti-aging skin care regimen will focus more on changes in pigmentation, and the more visible appearance of age spots, spider veins, and sun-damaged skin.
