The extract from skin of the fruit lemon (a.k.a. Citrus limon) or lemon peel extract, is also acidic in nature, quite like the fruit itself. Its acidity makes it useful as an astringent or toner, and also as an anti microbial. Additionally, it has a bleaching action too; lightening dark spots caused by sun damage, aging or acne. As a toner, it controls skin’s oiliness and restores the natural pH balance. It also soothes mild skin rashes or redness; and removes impurities and dead cells. It is also known to stimulate new cell growth, fight acne and enhance elasticity of the skin.
