On the Use of Hyaluronic Acid and Glycolic Acid in Combination
The way of skin care is that the combination of ingredients is like a spoon, and it needs to be properly weighed in order to complement each other. The combination of hyaluronic acid and glycolic acid is actually the key point of skin care.

Hyaluronic acid has excellent moisturizing effect. Its unique molecular structure can absorb several times its own weight of moisture, making the skin moist and full at all times, just like the petals of dew in the morning, delicate and ready to drip. It forms a moisturizing film on the surface of the skin to block the invasion of dry air from the outside world, stabilizing the internal environment of the skin and preventing the suffering of water loss.

Glycolic acid is the leader of the fruit acid family. Its small molecules can quickly penetrate the stratum corneum of the skin and promote the metabolism of keratinocytes. It can loosen the adhesion between keratinocytes and make the old waste keratin fall off naturally, so that the skin surface is smooth and delicate, and it glows with a new radiance. And glycolic acid can stimulate the synthesis of collagen in the dermis, enhance the elasticity and toughness of the skin, and delay the process of skin aging.

However, the combination of the two also needs to follow a certain order. It is advisable to use glycolic acid to open the absorption channel of the skin first. After glycolic acid removes the old waste keratin, the permeability of the skin is enhanced. At this time, hyaluronic acid is used, which is like a boat running along the water. Hyaluronic acid can penetrate into the deep layers of the skin more efficiently and exert its If the order is reversed, apply hyaluronic acid first to form a moisturizing film. Glycolic acid may be difficult to penetrate and cannot fully exert its effect of promoting keratin renewal.

And the frequency of use also needs to be considered. Glycolic acid is irritating to a certain extent and should not be used too frequently. For beginners, you can use it once or twice a week, and then increase the frequency as appropriate after the skin adapts. Although hyaluronic acid is relatively mild, it should also be used moderately according to your skin type. For dry skin, you can increase the number of uses appropriately to replenish sufficient moisture; for oily skin, you need to control the dosage to avoid overburdening the skin and triggering an imbalance in oil secretion.

Furthermore, sun protection is particularly important during use. Glycolic acid makes the skin new, more delicate, and less resistant to ultraviolet rays. If you don't pay attention to sun protection, the skin is vulnerable to ultraviolet damage, and there will be problems such as pigmentation and sunburn. Therefore, after using the two with skin care during the day, be sure to apply sunscreen, or take physical sun protection measures, such as parasols, sun hats, etc., to take care of the skin in an all-round way.

In short, hyaluronic acid and glycolic acid are properly matched, such as a good doctor dispensing medicine, which can bring many benefits to the skin. However, you need to pay attention to your own skin type, follow the order and frequency of use, and take into account sun protection, so that the skin can always maintain youthful vitality and bloom.
