Alpha-hydroxy acids (AHAs) are derived from fruit sugars, such as glycolic acid, which comes from sugar cane. The glycolic acid sloughs off the upper layers of the skin, making way for beautiful new cell growth.

Skincare products containing AHA are quite common in the market nowadays; but for those who still prefer natural ingredients chemicals-free, try this easy DIY formula from Gorgeously Green: 8 Simple Steps to an Earth-Friendly Life by Sophie Uliano.

INGREDIENTS:
1/4 cup lemon juice
1/4 cup apple juice
1/4 cup grape juice
1/4 cup cane sugar

Blend all of the ingredients in a glass jar. Apply to your face with an organic cotton ball. Leave on for 10 minutes and rinse off. The mixture will keep for up to four days in the refrigerator.
