Lactic Acid vs. Glycolic Acid: Which Is Best for My Skin?

In the field of skin care, lactic acid and glycolic acid are two very common ingredients, each of which has unique effects and application scenarios. For many people, choosing lactic acid or glycolic acid for skin care can be confusing. This article will analyze these two ingredients from multiple perspectives to help you better understand their characteristics and choose the most suitable product for you.

Lactic acid and glycolic acid basic difference

Both lactic acid and glycolic acid belong to the class of salicylic acid, but they differ in chemical structure and mechanism of action. Lactic acid is an acidic substance naturally present in many fruits and has a strong moisturizing and softening effect on the skin. Glycolic acid, on the other hand, is a more efficient exfoliant that penetrates deeper into the surface of the skin, helping to remove dead skin cells and promote skin renewal.

Lactic Acid's Skin Care Efficacy

Lactic acid mainly moisturizes and softens the skin in skin care. It can help the skin lock moisture, enhance the skin's barrier function, thereby improving dry and rough skin. Lactic acid also has a certain antioxidant effect, which can help reduce the damage of free radicals to the skin and delay aging. For sensitive muscles, the mild nature of lactic acid makes it a safer choice because it does not cause excessive skin irritation.

Glycolic Acid's Skin Care Efficacy

Glycolic acid is more exfoliating than lactic acid. It can effectively remove dead skin cells on the surface of the skin and help the skin stay smooth and delicate. Glycolic acid can also promote the metabolism of the skin, accelerate the formation of new cells, thereby improving the skin color and dull problems. Glycolic acid also has a certain antibacterial effect, for easy acne skin, it can help reduce the occurrence of acne. However, due to the strong irritation of glycolic acid, it is necessary to pay attention to the concentration and frequency when using it to avoid excessive irritation to the skin.

How to choose lactic acid and glycolic acid?

The choice of lactic acid or glycolic acid depends on your skin type and specific needs. If you have dry or sensitive skin, lactic acid may be more suitable for you because it has a strong moisturizing and soothing effect and can help restore the skin's barrier function. And if your skin is greasy or has obvious cutin buildup problems, glycolic acid may be more suitable for you, because it can more effectively remove dead skin cells and improve the texture of the skin.

When using lactic acid and glycolic acid, you also need to pay attention to the concentration and frequency of use of the product. Generally speaking, the concentration of lactic acid is low and can be used every day, while the concentration of glycolic acid is high. It is recommended to use it 2-3 times a week to avoid excessive skin irritation.

Summary

Lactic acid and glycolic acid have their own unique efficacy and application scenarios in skin care. Lactic acid is suitable for skin that needs to moisturize and soothe, while glycolic acid is suitable for skin that needs to exfoliate and improve skin quality. The choice of ingredients should be based on your skin type and specific needs. When using, you need to pay attention to the concentration and frequency of the product to avoid unnecessary irritation to the skin.
