On the timing of application of glycolic acid
If you want to make good use of glycolic acid, you should know the timing of its application. The properties of glycolic acid, the effect of skin care, varies from time to time.

If the skin is trapped in keratin congestion, the metabolism is slow, and the face is dull, glycolic acid should be used at this time. It can gently exfoliate the skin, making the skin re-transparent, just like melting snow in spring, making the skin like new buds, fresh and shiny.

And if the skin shows fine lines and gradually loses elasticity, like spring leaves showing veins, it should also be used in a timely manner. Glycolic acid can promote collagen regeneration, such as spring rain moisturizing wood, helping the skin to tighten, fine lines fade away, and return to a full state.

When the skin is sensitive and weak, or when used with caution. When the skin is sensitive, it is like a weak willow in the wind, and the ethanol is slightly acidic, afraid of being hurt by touch. It must be done when the skin is calm and stable, so as to avoid discomfort.

Therefore, when using glycolic acid, it is necessary to observe the condition of the skin, the appropriate time, and the situation, in order to obtain its good use, so as to achieve the best condition of skin care.
