On the Combination of Glycolic Acid and Vitamin C The use of
Glycolic Acid is gentle and has the ability to rejuvenate the skin, which can clear the scale of the skin and promote the renewal of keratin. Vitamin C is a strong antioxidant, which can whiten the skin and resist the aging of the skin. If the two are used together, it may complement each other.

The method of combining glycolic acid and vitamin C
When using glycolic acid, it is advisable to start with a low concentration, such as 2% - 5% glycolic acid products, and gradually increase tolerance. After cleansing, take an appropriate amount of glycolic acid products and apply them evenly to the face, avoiding the eye area and lip area. Apply it every two or three days for the first time, and gradually increase it to once a day when the skin gets used to it.

As for vitamin C, it should be done step by step. Stable vitamin C derivatives can be selected first, such as magnesium ascorbate phosphate, etc. After cleansing and toning, apply an appropriate amount of vitamin C products to the face, gently rub until absorbed.

When using both, you can apply glycolic acid first, and then apply vitamin C products after drying. Or use it at different times, such as using vitamin C in the morning to prevent daytime oxidation, and using glycolic acid in the evening to purify and rejuvenate the skin.

Use both
and pay attention to the skin reaction. Glycolic acid is stripping and may cause temporary sensitivity to the skin. If used in combination with vitamin C, it may increase this feeling. Before use, it is recommended to test the sensitivity behind the ear or a small piece of skin to observe whether there is redness, swelling, itching and other discomfort.

And both are acidic to a certain extent, and may lower the pH of the skin when used. If the skin is intolerant, or the barrier is damaged, it should be supplemented with mild moisturizing products in a timely manner to protect the skin barrier.

In addition, during the concomitant use, special attention should be paid to sun protection. Glycolic acid and vitamin C can both increase the skin's sensitivity to light. If there is no protection, it is easy to cause sunburn and tanning, which makes the whitening and anti-aging effect counterproductive. It is recommended to use high-multiple sunscreen products when going out, and physical sunscreen is also required, such as parasols, sun hats, etc.

In general, the use of glycolic acid and vitamin C together, if the method is appropriate, nourished, or a good strategy for skin rejuvenation, it is necessary to adapt to the skin and proceed with caution.
