Comparison of Lactic Acid and Glycolic Acid Rejuvenation

Lactic acid and glycolic acid rejuvenation are both common skin care methods. The two have their own characteristics. Let's try to compare them.

Lactic acid is one of the fruit acids. Its molecules are relatively large and have a mild texture. Due to its mild properties, lactic acid rejuvenation is especially suitable for people with sensitive skin. Applied to the skin, it can slowly release active ingredients, gently exfoliate and promote skin metabolism. Long-term use can make the skin gradually smooth and delicate, and can improve the skin's hydration ability, making the skin moist and radiant.

Glycolic acid is also an important member of the fruit acid family. Its molecules are small and have strong penetrability. This property makes its skin rejuvenation effect significant and rapid, which can penetrate deeper into the bottom layer of the skin and effectively improve a variety of skin problems. For acne skin, glycolic acid can dredge blocked pores and reduce the breeding of acne; for dull skin tone, it can accelerate melanin metabolism and brighten skin tone. However, due to its strong effect, sensitive skin should be used with caution. A little carelessness can easily cause skin discomfort, such as redness, tingling, etc.

In terms of the scope of application, lactic acid rejuvenation has a wider audience, and can be tried on all kinds of skin. Sensitive skin is better tolerated when used. Glycolic acid rejuvenation is more targeted at people with more serious skin problems, such as frequent acne, uneven skin tone and thick stratum corneum.

From the frequency of use, lactic acid rejuvenation can be used relatively frequently, such as once or twice a week, depending on the degree of skin tolerance. Glycolic acid rejuvenation should be used less frequently because of its strong effect, usually every two to three weeks.

In short, lactic acid and glycolic acid rejuvenation have their own advantages and disadvantages. Users should choose carefully according to their own skin conditions to achieve the best skin care effect and avoid skin damage.
