Then it changes or stimulates the epidermal nerve endings, causing redness.

And glycolic acid initiates the renewal of keratinocytes, promotes the exfoliation of the old keratin, the new keratin is still weak, and the skin barrier is temporarily damaged. External evil is easy to invade, capillary stress expands

In addition, the release of glycolic acid or inflammatory mediators. Under its stimulation, immune cells respond to it, releasing histamine and other mediators, resulting in increased vascular permeability, extravasation of blood components, skin redness and/or heat sensation.
