Retinoic acid cream and glycolic acid, which is better
Retinoic acid cream and glycolic acid are both commonly used in skin care, but each has its own strengths, and the advantages and disadvantages depend on the specific situation.
Retinoic acid cream, its function is to promote the renewal of stratum corneum cells, which can accelerate the shedding of skin surface cells, and replace them with new cells, making the skin more delicate and smooth. It can also improve the keratinization of hair follicles, prevent and reduce the formation of acne, and is quite effective in the treatment of acne vulgaris. At the same time, it has a certain effect on the improvement of skin texture and the reduction of wrinkles, because it can stimulate collagen production and enhance skin elasticity. However, it also has drawbacks. When used for the first time, the skin may feel irritated, such as redness, desquamation, burning, etc., and it is more sensitive to sunlight. Pay attention to sun protection during use, otherwise it will easily cause skin damage.
Glycolic acid belongs to the fruit acid category, which can loosen the connection between keratinocytes and thin the stratum corneum, thereby improving skin permeability and promoting skin absorption of skin care products. It also has a certain moisturizing effect, which can make the skin hydrated. It performs well in improving dull skin tone and brightening skin, fading pigmentation and even out skin tone. And compared with retinoic acid cream, its irritation is relatively weak, and most people have better tolerance. However, improper use of high-concentration glycolic acid may also burn the skin, causing redness, swelling, pain and other symptoms.
If it is mainly used to treat acne, and the skin tolerance is acceptable, retinoic acid cream may be the top choice, and its effect on the pathogenesis of acne is more direct and effective. However, if you only want to improve the dullness and roughness of the skin, improve the gloss of the skin, and the skin is more sensitive, glycolic acid is more suitable, its irritation is less, and the safety is higher.
In short, retinoic acid cream and glycolic acid have their own strengths, and there is no absolute advantage or disadvantage. The key is to choose carefully according to personal skin type, skin problems and tolerance to achieve the best skin care effect.
