On the Compatibility of Glycolic Acid, Hyaluronic Acid and Retinol
The key to skin care is the compatibility of ingredients. Glycolic acid, hyaluronic acid and retinol are all excellent skin care products, but the method of matching them needs to be explored in detail.

Glycolic acid is a type of fruit acid and has excellent exfoliation ability. It can loosen the connection between keratinocytes, promote the shedding of old waste keratin, make the skin surface smooth and delicate, and stimulate collagen regeneration, improve skin texture, and make the skin glow.

Hyaluronic acid, also known as hyaluronic acid, is famous for its powerful moisturizing effect. It can grab and lock in a large amount of moisture, create a hydrated environment for the skin, make the skin full and full, relieve dryness, and enhance skin elasticity.

Retinol, a derivative of vitamin A, is outstanding in the field of skin anti-aging. It can accelerate cell metabolism, promote collagen synthesis, reduce wrinkle formation, improve skin firmness, and also improve acne and other problems.

However, the compatibility of these three must be done with caution. Glycolic acid is acidic, which can thin the stratum corneum of the skin and increase skin permeability. Retinol itself has a certain irritation to the skin, and the use of the two may exacerbate skin irritation, causing redness, tingling, desquamation and other discomforts. If the skin's tolerance is not good, it may be unbearable to match it rashly.

Although hyaluronic acid is a good moisturizing agent for the skin, it can relieve some of the dryness caused by glycolic acid and retinol. However, when glycolic acid and retinol are too stimulated, hyaluronic acid is difficult to completely offset its negative effects.

Therefore, if you want to use glycolic acid, hyaluronic acid and retinol in combination, the first priority is skin tolerance. Those with strong skin tolerance can try it on a small scale first, observe that there is no discomfort, and then gradually expand the use area. And the frequency of use should be from low to high, such as once a week at the beginning, and increase the number of times as appropriate after the skin adapts. In terms of use time, it is recommended to use it at night, because the skin repair ability at night is strong, and it can avoid the risk of increased irritation caused by sunlight exposure. During use, if the skin feels uncomfortable, it should be stopped immediately and professional advice should be sought.

In short, glycolic acid, hyaluronic acid and retinol are properly combined, which can achieve twice the result of skin care with half the effort; if they are not carefully matched, it will hurt the skin. To maintain the skin, scientific prudence should be taken into account.
