How does Glycolic acid treat acne?

Glycolic acid helps in reducing the severity and frequency of acne in a number of ways and also further contributes towards fading away the acne causing scars.

Firstly, it has drying properties and which help in cutting off the excess oil from the skin and dehydrate the bacteria thereof by killing them.

It also functions as a good exfoliation agent and removes the dead skin cells clearing off the clogged pores of the skin and unclogging it so that the excess sebum which was otherwise accumulated beneath the surface of the skin can move out.

The exfoliation and removal of dead skin cell further promote the growth of new cells to replace the dead cells.

Glycolic acid, in its group of alpha hydroxyl acid, has the smallest molecule which helps in penetrating the layer of the skin to the deepest and facilitates treatment not only on the upper layers but to the very core of it.

It can further be used with other bleaching agents like hydroquinone to affect the removal of scars and marks on the skin.

The mechanism of action behind this is that after glycolic acid has removed the dead skin cells from the surface of the skin, the bleaching agent is better able to penetrate under the layers of the skin and start its action from the very root of the skin layers.

This makes it more effective in treating acne scars and hyperpigmentation.
