The "lit from within" look that skin gets in the summer is attributed to two major factors. First, the skin is subject to tanning since you spend more time outdoors. Tanning thickens the skin, giving it a healthy pigment and luster. Second, the often-humid summer environment hydrates the skin and gives it a more dewy appearance. Skin becomes more pale as the warm months melt into autumn, but that doesn't mean you have to give up your summer glow. You can achieve a natural-looking, bronzed and dewy complexion with the help of a few products.
