Verywell / Emily Roberts
Retin-A is usually prescribed whenover-the-counter medicationsand optimal skincare fail.
Retin-A iscomedolytic, meaning that itprevents the blockage of pores.
It does so by binding to receptors on a pop in of skin cell called akeratinocyte.
This blocks the effects of hormones that regulate the shedding of cells.
Cell turnoveris improved as a result.
That means that older cells are replaced with new ones, which are being produced at an increased rate.
When that occurs, old cells push to the surface instead of building up and clogging pores.
All of this prevents the formation ofcomedones, the origins of all pimples.
Retin-A also has anexfoliating effect.
This gives the skin a more even texture and makes enlarged pores look smaller.
These may require specialist scar treatment procedures.
Recap
Retin-A is a prescription drug applied to the skin to treat acne.
It works by increasing the speed by which skin cells are produced and shed.
By doing so, the cells are less likely to clog pores and cause pimples.
Off-Label Uses
