On the method of using vitamin C and glycolic acid together
If you want to understand the way of using vitamin C and glycolic acid together, you need to study its properties and rationale in detail. Vitamin C has antioxidant properties, can help resist the damage of free radicals in the skin, and can promote the production of collagen, making the skin bright and elastic. Glycolic acid belongs to the class of fruit acids. Its molecules are small, well penetrated, can exfoliate, smooth pores, promote skin metabolism, and make the skin delicate and smooth.

However, if you use both, you should not be careless. Vitamin C is acidic, and glycolic acid is also acidic. If you use it together, the acidity will be superimposed, or the skin will be intolerant. Those with delicate skin are prone to redness and tingling. Therefore, before using it together, check the skin's tolerance. Those with strong skin may try it; those with sensitive skin should try it on a small scale first to see if it is uncomfortable.

When using it, the timing should also be used. Vitamin C can be used during the day for antioxidant skin care, because it can help the skin resist the harm of the daytime environment; night use glycolic acid, the skin metabolizes vigorously at night, and glycolic acid can better exert the effect of exfoliation and metabolism promotion. And at the beginning of the combination, the concentration should be low and gradually increased to give the skin the opportunity to adapt.

In addition, using these two, sun protection is essential. Glycolic acid thins the skin's keratin and increases its sensitivity to light; although vitamin C has antioxidant power, it also needs sunscreen protection to avoid skin damage due to light. High-power sunscreen products should be used during the day, and sunshades are also indispensable.

In short, when vitamin C and glycolic acid are used together, if properly, they can achieve skin beauty; if they are not careful, the skin may suffer from it. The skin must be carefully examined and acted according to reason, in order to make the skin healthy and beautiful.
