The Difference Between Glycolic Acid and Retinol
Recently, there has been a lot of discussion on skin care methods. The advantages and disadvantages of glycolic acid and retinol in skin care are often a hot topic, just like the ancient argument, each holds its own opinion.

Glycolic acid belongs to the fruit acid family, with tiny molecules that can quickly penetrate the surface of the skin. Its first function is to exfoliate the skin, which can remove the old exfoliation of the skin and make the skin regain its luster, just like the spring breeze blowing away dead branches and the new green is first to bloom. Often used in daily skin care products with low concentrations, it can make the skin gradually smooth and the skin tone even. If the skin is rough and dull, using this is like seeing the sun through the clouds, and the skin tone is expected to be bright.

Retinol is a derivative of vitamin A, which helps the skin's metabolism a lot. It can stimulate collagen regeneration, make the skin firm and elastic, just like injecting vitality into the skin, making the skin feel full after a long drought. However, retinol is irritating to a certain extent. Beginners need to try a small amount gradually, and it can only be increased when the skin adapts. If you are too hasty, you may be intolerant to the skin and cause redness, swelling and discomfort.

On the Reddit forum, everyone expressed their opinions. Those who like glycolic acid say that it has a gentle effect, suitable for people who are new to skin care and have sensitive skin. Daily use can stabilize the skin and gradually improve. There are also people who praise retinol, saying that its effect is strong, and it has a significant effect on wrinkles, sagging and other problems. Although the skin may react at the beginning of use, the effect after adaptation is amazing.

In fact, the two have their own advantages. If you want to gently rejuvenate the skin and improve slight roughness and dullness, glycolic acid is the best choice; if you want to deeply resist aging and solve the problem of wrinkle relaxation, retinol is better. However, the way of skin care, your mileage may vary, you need to choose it carefully according to your own skin characteristics to achieve the best effect and keep the skin youthful and radiant.
