You’re scrolling through Instagram and you see yet another influencer swear by their latest microneedling session.

But what is microneedling, and what actually happens to your skin?

Microneedling is a cosmetic procedure that is done to promote an increase in blood circulation (viaHealthline).

The procedure includes pricking the skin with tiny sterilized needles to trigger the body’s natural healing process.

There are many side effects to microneedling, and bleeding isn’t uncommon (viaNewBeauty).

According toMedical News Today, bleeding is more common after a deeper treatment.

One of the most common aftereffects from microneedling is red skin.

In addition to your skin feeling irritated, it is more susceptible to sun damage than it usually is.

Another reaction to look out for is some slight peeling or shedding, according toNewBeauty.
