On the appropriate use sequence of glycolic acid and vitamin C
for skin care, glycolic acid and vitamin C are both commonly used things. However, the order of use of the two is quite critical, and it is related to the quality of efficacy.

Glycolic acid has the power of exfoliating and rejuvenating the skin. It can gently remove the aging keratin on the surface of the skin, open the pores, make the skin surface smoother, and promote the absorption of subsequent skin care products.

Vitamin C is known as antioxidant, which can resist the damage of free radicals to the skin, fade spots, brighten the complexion, and make the skin shine again.

If glycolic acid is applied first, followed by vitamin C, there are many benefits. Glycolic acid opens the channel for skin absorption, so that subsequent vitamin C can more smoothly penetrate the deep layers of the skin, giving full play to its antioxidant ability. And after glycolic acid treatment, the skin's absorption of nutrients is enhanced, and the whitening and anti-aging effects of vitamin C are also improved.

On the contrary, if vitamin C is applied first, followed by glycolic acid, it may be unfavorable. The exfoliation effect of glycolic acid may affect the retention and action time of vitamin C on the surface of the skin, resulting in its full effect. And the superposition of the two, or the stimulation of skin building, is more likely to cause discomfort for sensitive skin.

Therefore, in order to achieve the best skin care effect, it is advisable to use glycolic acid first, wait for the skin to soothe a little, and then use vitamin C. In this way, the two complement each other, which can make the skin care work twice with half the effort and radiate the beauty of natural health.
