Comparison of Salicylic Acid and Glycolic Acid on Reddit

Recently, in the Reddit community, there has been a heated discussion about the difference in efficacy between salicylic acid and glycolic acid. Both are commonly used ingredients in the field of skin care, but their characteristics and applicable skin types are different.

Salicylic acid, fat-soluble, can penetrate deep into the pores, effectively clean the oil and dirt in the pores, and is effective for oily and acne-prone skin. It can loosen the connection between keratinocytes, promote keratin renewal, and reduce acne inflammation, so it is often used to treat skin problems such as acne.

Glycolic acid is a water-soluble fruit acid with small molecules, which can quickly penetrate the surface of the skin, improve skin metabolism, improve dullness, and make skin smoother and more delicate. Glycolic acid is often used to improve skin texture, fade pigmentation and fine lines, and is suitable for a variety of skin types, but it should be used with caution when used on sensitive skin.

On Reddit, many users shared their personal experiences. Those with oily skin said that salicylic acid effectively controls oil secretion and reduces the growth of acne; those with dry skin said that although glycolic acid can brighten skin tone, it may be slightly tingling in the early stage of use, and tolerance needs to be gradually built up.

In short, the choice of salicylic acid or glycolic acid depends on the individual skin type and skin care needs. Before using a new skin care product, it is wise to try it on the local skin to see if there is any discomfort.
