On the comparison between glycolic acid and salicylic acid
There are glycolic acid and salicylic acid today. Both are commonly used ingredients in skin care, but their performance effects are different, so they should be analyzed in detail.

Glycolic acid is a type of fruit acid, with small molecules, which can easily penetrate into the surface of the skin. Its main function is to promote keratin renewal, which can gently peel off the accumulated old waste keratin, making the skin return to a smooth and delicate state, just like the spring breeze blowing away dust, making the skin look brand new. And it can help the skin absorb moisture and improve the skin's hydration. After use, the skin is like a sponge that absorbs moisture, moisturizing and radiant. It is also quite effective in improving dull and even skin tone, just like lighting up the light for the skin to make it shine.

And salicylic acid, a fat-soluble ingredient, is good at penetrating deep into the pores. It can effectively dissolve clogged oils in pores and clean pores, such as dredging river channels, so that pores are unobstructed, so it has significant effect on improving oily skin problems such as acne and acne. At the same time, it has certain anti-inflammatory properties, which can relieve skin inflammation and reduce redness, swelling and discomfort, just like applying a layer of soothing medicine to inflamed skin.

However, both also have their own taboos. Although glycolic acid is mild, when it is in high concentration, it is highly irritating to the skin. Those with sensitive skin should use it with caution and need to build tolerance step by step. Salicylic acid has a certain impact on the skin barrier due to fat solubility. It should also be used in moderation if it is used in large quantities for a long time or causes dry and desquamation of the skin.

In short, if you want to choose one of the two, it should depend on your skin type and needs. For dry and sensitive skin, if you want to gently rejuvenate and moisturize, glycolic acid may be a good choice; for oily and acne skin, if you want to clean pores, resist inflammation and remove acne, salicylic acid is more suitable. Only by making careful choices and using it reasonably can you achieve the best state of skin care and make your skin healthy and radiant.
