6 Less Common (And More Severe) Laser Hair Removal Side Effects
Laser hairserious, long-term side effects
- Blistering/Burns
Blistering or burns can occur as a side effect of laser treatment itself or due to direct exposure to sunlight right after treatment. It can also occur due to treating broken, tattooed, tanned, or very dark skin. - ScarringAny marks left behind from laser hair removal typically go away after a few days, but in some instances, they can become scars.
- Eye InjuryThe light emitted from the lasers can cause injury or blindness – always wear any protective eyewear your physician provides you when undergoing laser treatment.
- Cold Sore OutbreaksHerpes simplex can be stimulated by sunlight – if you have a cold sore, laser hair removal treatment may trigger the virus to become active and cause an outbreak on treated skin.
- Permanent Skin Discoloration
Laser hair removal can result in hyperpigmentation (areas of skin that are darker than surrounding skin) or hypopigmentation (areas of skin that are lighter than surrounding skin). - InfectionThe most common type of infection caused by laser hair removal is folliculitis, the inflammation and infection of hair follicles.
The American Academy of Dermatology advises that laser hair removal can be dangerous in inexperienced hands – having your treatment performed by a medical doctor who is extremely skilled in using lasers and caring for skin can greatly reduce the risk of possible side effects.

Can laser hair removal result in increased hair growth?
No evidenceincreased hair growth
In some cases, laser hair removal may not offer the permanent, totally-hairless results you may have been expecting, but even if it doesn’t reduce your body hair as much as you’d hope, it certainly shouldn’t cause MORE hair to grow than you had when you started.
Is laser hair removal safe for sensitive areas like the face or bikini line?
Yes, laser hair removal is safe for the face and bikini line. It’s typically more painful, but it can still be done and it’s very effective on pubic hair and PCOS facial hair.
How to Care for Your Skin to Avoid Side Effects of Laser Hair Removal Treatments

Before laser hair removal:
- Shave the area you’re going to treat. Failure to shave the area can cause burns.
- Clean the area. Be sure your skin is free of any creams or gels.
- Wear proper eye protection to avoid eye injury.
- Avoid sun exposure. Laser hair removal should not be done on tanned or burned skin.

After laser hair removal:
- Moisturize. This helps with basically every common side effect – itchiness, dryness, irritation, etc.
- Avoid sun exposure. For at least a week following treatment, use SPF 50+ on the treated area whenever it may be exposed to sunlight.
- When in doubt, consult your physician. They’ll gauge whether any side effects are normal and may help to treat any abnormal burns or infections before they lead to scars.

Introducing IPL: A Gentle Alternative to Laser Hair Removal

As far as IPL vs laser hair removal goes: it’s similar to laser, only it uses broader light pulses, making it less painful, easier to treat a larger area, and FDA-cleared for safe home use. IPL treatment is less taxing on skin as well, so there are fewer serious side effects and IPL aftercare is even easier. IPL is also significantly less expensive than laser – you can get Lumi for a one-time cost of $229 USD and use it to treat your entire body if you want to. IPL is worth looking into if you’re concerned about the side effects of laser hair removal.
