Taking glycolic acid and vitamin C as the main herb
to describe the present herb
The effect of glycolic acid and vitamin C in skin care is quite popular. Although the herb of the past did not contain the names of the two, there may be a hidden reason.

Glycolic acid has the power of gentle exfoliation. It can exfoliate the old and waste exfoliation of the skin, rejuvenate the muscle surface, just like melting snow in spring, and revitalize the earth. It can dredge pores, make the skin breathe smoothly, like a breeze entering the window, and renew the air in the room. And it helps to retain moisture, moisturize the skin, like dead wood meets rain, and gradually moisturize it.

Vitamin C is a strong antioxidant. It can resist the harm of free radicals and slow down the aging process of the skin. It is like a strong shield of the city, protecting the city from the people. It can lighten pigmentation and even out the skin tone, making the skin bright like the moon, clear and flawless. It can also promote collagen production, making the skin firm and elastic, like a newly woven brocade, smooth and full of tension.

Use glycolic acid and vitamin C in combination to complement each other. Glycolic acid opens the door of the skin, vitamin C flows in smoothly, and the effect is doubled. From an ancient perspective, the two are compatible, such as yin and yang, hardness and softness, playing a wonderful song of skin care together.

Although it is not found in ancient books today, it is reasonable to infer that it is in the way of skin care, or a good prescription for future generations. With time, in-depth investigation may add a new chapter to the study of Materia Medica, benefiting everyone's skin.
