DIY: How To Make
LIGHTENING CREAM

Ingredients needed:

 KOJIC ACID.
 Kojic acid is a by-product in the fermentation process of malting rice. Kojic's acid primary use — and benefit — is to lighten visible sun damage, age spots, or scars. This can result in an anti-aging effect on the skin. In addition to skin-lightening effects, kojic acid also contains some antimicrobial properties. ... This can help treat acne caused by bacteria in the skin.


GLYCERIN
Glycerin is great for helping your skin retain moisture, repairing damage, and protecting your skin from infections. But while glycerin can improve overall skin health, it isn't intended to whiten or lighten skin, nor is there evidence supporting its ability to reduce hyperpigmentation.
