On the order of use of hyaluronic acid and glycolic acid
The method of skin maintenance is related to the order of application of hyaluronic acid (Hyaluronic Acid) and glycolic acid (Glycolic Acid), which is quite crucial.

Hyaluronic acid has excellent moisturizing power, which can keep water in the skin and make it moist and full. Glycolic acid belongs to the category of fruit acids, which can exfoliate, promote skin metabolism, and rejuvenate it.

If glycolic acid is applied first, because of its exfoliating ability, the skin's surface exfoliates, and the skin needs more moisture at this time. Following the use of hyaluronic acid, hyaluronic acid can take advantage of the skin's thirst for water, fully replenish water and moisturize. The two complement each other and achieve the best effect.

However, if the order is reversed, apply hyaluronic acid first. Although the skin is temporarily hydrated, then use glycolic acid later. When exfoliating, the retained moisture may be lost, and the skin may feel uncomfortable due to the stimulation of glycolic acid.

Therefore, the order used should be glycolic acid first, then hyaluronic acid. In this way, the effects of the two can complement each other, nourishing and radiant the skin.
