Lemonade can whiten the skin. One of the well-known benefits of lemonade is that it can make our skin more shiny and whiter.

It has good antioxidant effect, can dilute melanin in the skin, improve the self-repair ability of the skin and whiten the skin. Drinking too much lemonade will lose the whitening effect. Lemon contains some photosensitive substances, which are easily absorbed by human body when taken orally, and human skin is exposed to the sun. Under the interaction of these photosensitive substances and sunlight, it is not only unable to whiten the skin, but also easy to make the skin darker and even more sensitive.
