Pharmaceutical theory
There are strange recipes in the world, with ten parts of glycolic acid and two parts of salicylic acid. Glycolic acid is mild in nature, can peel off the old and waste exfoliation of the skin, and make the skin new. If spring returns to the earth, the grass and trees are prosperous, making it smooth and shiny. Salicylic acid is fat-soluble and can penetrate deep into the pores, dredge and block, such as dredging river channels, making the pores smooth, preventing acne and reducing inflammation, and leveling the skin.

The two are compatible and complement each other. Glycolic acid opens the surface, and salicylic acid clears the inside. When used properly, skin blemishes gradually disappear and the color is even. However, the way to use medicine is to weigh. Although this agent is wonderful, those with delicate skin may be intolerant. When using it for the first time, try it in small quantities, and observe the response of the skin, like walking on thin ice, to prevent drastic changes.

When a doctor uses a prescription, he must carefully examine the nature of the patient's skin, the difference in age, and the difference in disease, and then apply the medicine as appropriate. Such as good work and jade carving, careful carving, can play the work. Do not act recklessly, causing the medicine to harm the body. Those who are good at medicine can make the skin rejuvenated and radiant; those who are not good at using it will damage the skin and suffer endlessly. The trade-off of this medicine cannot be ignored.
