The method of making glycolic acid serum
If you want to make glycolic acid serum, you should first prepare all kinds of materials. The required ones are glycolic acid, moisturizer, thickener, preservative and water. The concentration of glycolic acid varies depending on the use, so it should be weighed accurately.

Take an appropriate amount of water first and put it in a clean container. Slowly pour the moisturizer into the water and stir it well. The moisturizer can lock in water and moisturize, so that the serum has a moisturizing effect.

Then, add the thickener in sequence. The thickener can adjust the texture of the serum and make it easy to apply. When adding, it is best to sprinkle it slowly and keep stirring to prevent agglomeration.

When the thickener is evenly mixed with water and moisturizer, slowly drop in the accurately weighed glycolic acid. When dripping, pay close attention to the reaction of the solution and keep stirring. Glycolic acid is corrosive to a certain extent, and the operation must be cautious.

Finally, add an appropriate amount of preservative. The preservative can keep the serum intact for a long time, but the dosage should be moderate to avoid irritating the skin.

After the mixture is completed, stir at high speed with a mixer until the serum is uniform and delicate in texture and has no granular feel. Then, move the prepared glycolic acid serum into a clean, sealed container and place it in a cool and dry place, protected from direct light. In this way, the glycolic acid serum is formed. Those who use it should try it before a small area of skin, and it can be used normally without discomfort.
