Once you’ve reached a certain age, you are inevitably going to develop some signs of aging, whether it be fine lines or wrinkles. When you’re taking care of skin in your early-to-late 30’s, you’ll want to incorporate an anti-aging serum into your daily routine. This will penetrate deeper into your skin, and help to slow the development of more lines and wrinkles. You may notice that your skin tends to become dryer on your body as well, and you might have to use a more penetrating or hydrating lotion after showering.
