Between heaven and earth, there are two things, one glycolic acid and one lactic acid, both of which are in the field of biochemistry and have extraordinary functions.

Glycolic acid is mild in nature, on the skin, it can soften the cuticles, rejuvenate its luster, and help the skin replace its new age, like spring rain, quietly nourishing. It can enter the bottom of the muscle, clear the old quality, and make the skin delicate and smooth, like a new life.

Lactic acid is not inferior, and has unique power. In the leavening of things, it is often the key. It can lead to the change of things and promote the transformation of their quality. In the diet, there are also traces, which can add a unique taste and increase the charm of things.

Although the two are different in nature, they both do unique things in the world, either benefiting the skin or assisting biochemistry. They are the wonders of heaven and earth, each developing its ability and adding the color of all things together.
