Glycolic acid is used after microneedling. On the occasion of microneedling, the skin is broken to promote new life. Although the injury is minimal, the skin's state is different from usual. Glycolic acid is active and has a significant effect on the skin. However, when to use it after microneedling is very particular.

After microneedling, the skin is initially damaged and opened. At this time, the skin is at the beginning of self-repair, just like a swaddling baby, and needs careful care. If you use glycolic acid rashly, because it is irritating to a certain extent, it may disturb the order of skin repair, causing skin discomfort, redness, swelling, and pain.

One or two days after surgery, the skin's wound has not healed and its vitality has not recovered. Gentle maintenance should be the main one to avoid the stimulation of glycolic acid. After three to five days, the skin's wound will gradually close, but it is still delicate. At this time, you can try glycolic acid, but it must be diluted and used. Pay close attention to the skin's response. If there is any discomfort, stop using it immediately.

After five days, the skin repair will gradually become better, and the tolerance will increase slightly. At this time, the concentration and frequency of use of glycolic acid can be gradually increased according to the condition of the skin. However, caution is still required. Due to the large differences in individual skin, or those who are sensitive, it is difficult to adapt to glycolic acid even after many days.

In short, the use of glycolic acid after microneedling is also timely and appropriate. It needs to be measured according to the course of skin repair and cannot be generalized in order to make glycolic acid help skin rejuvenate without the risk of damage.
