The Debate between Lactic Acid and Glycolic Acid

In modern times and the method of skin rejuvenation, lactic acid and glycolic acid are often the focus of hot discussion. Both belong to the family of fruit acids, but their properties and uses are different.

Lactic acid is derived from natural fermentation and has a mild nature. Its molecules are slightly larger and penetrate slightly into the skin. Therefore, when using lactic acid at the beginning, the skin is slightly irritated and suitable for sensitive skin. Its function is to moisturize the skin, increase the hydration of the stratum corneum, and make the skin smooth and shiny. Long-term use can slowly promote keratin renewal, lighten fine lines, and smooth the skin tone, so that the skin can regain its youthful color.

Glycolic acid is not the case. Its molecules are small and penetrate quickly and deeply into the skin. The effect is also more severe, which can strongly exfoliate the cuticles and quickly promote cell renewal. When used properly, it can quickly improve the roughness, dullness, light acne scars, and flat pores of the skin. However, because of its strong stimulation, if you don't tolerate the skin, use it rashly, or cause redness, swelling, and tingling.

Therefore, choose lactic acid or glycolic acid, and it should be broken off by the skin type. Sensitive and delicate people should try lactic acid first to gradually increase tolerance; those with strong tolerance want quick effect, and glycolic acid can be a good choice. However, the way of skin care is not achieved overnight. Choose it carefully and use it moderately to achieve the effect of skin rejuvenation.
