What Are the Side Effects of Laser Hair Removal?

It’s generally safe

If you’re tired of traditional hair removal methods, such as shaving, you may be interested in laser hair removal. Offered by a dermatologist or other qualified and trained expert, laser hair treatments work by stopping the follicles from growing new hairs. For most people, laser hair removal is safe. The procedure also isn’t linked to any long-term side effects.

Still, discussions about the side effects of laser hair removal abound. Although temporary and minor side effects can occur after the procedure, other effects are rare. Beyond that, any claims about links to your long-term health are unfounded.

Here’s what you need to know.

Minor side effects are common
Laser hair removal works by using small, high-heat lasers. The laser may cause temporary side effects immediately after the procedure. Skin irritation and pigmentation changes are the most common side effects.

Redness and irritation
Hair removal via laser can cause temporary irritation. You may also notice slight redness and swelling at the treated area. Still, these effects are minor. They are often the same effects you might notice after other types of hair removal, such as waxing.

Your dermatologist might apply a topical anesthetic before the procedure to minimize these effects.

Overall irritation should disappear within hours of the procedure. Try applying ice packs to help reduce swelling and any pain. You should call your doctor if you experience symptoms beyond slight irritation or if the side effects worsen.

Pigmentation changes
After laser treatment, you may notice slightly darker or lighter skin. If you have light skin, you’re more likely to have darker spots from laser hair removal. The opposite is true of people with dark skin, who may have lighter spots from the procedure. However, like skin irritation, these changes are temporary and aren’t usually a cause for concern.

Severe side effects are rare
Rarely, laser hair removal can lead to more severe side effects. Your risk increases if you use at-home laser kits or if you seek treatment from a provider who isn’t trained and certified.

Rare side effects of laser hair removal include:

Excessive hair growth in the area of treatment: Sometimes this effect is mistaken for hair shedding after the procedure
Changes to overall skin texture: You may be at an increased risk if you have tanned recently.
Scarring: This is most common in people who tend to scar easily.
Blisters and skin crusting: These effects may be caused by sun exposure too soon after the procedure.
Discuss these side effects with your doctor. Although they’re extremely uncommon, it’s still a good idea to be aware of them. Call your doctor if you show any of these symptoms after laser hair removal.
