The Lumenis LightSheer laser reduces hair density by targeting the pigment in hair follicles with pulses of light. Less commonly, it’s used to treat hyperpigmentation and spider veins, but its primary purpose is hair removal. It’s a diode laser, the most effective type for both light and dark skin.
How does the Lumenis LightSheer work?
- The laser energy follows the hair shaft down into the follicle, heats it, and destroys its ability to produce another hair.
- A full treatment series has six to eight sessions, each lasting 5 to 45 minutes, depending on area being treated. Your provider will recommend the best treatment cadence for each area of hair—somewhere between 4 and 16 weeks apart—to target all hair follicles at different stages of the growth cycle.
How should you prepare for LightSheer hair removal?
- You’ll need to stop waxing, tweezing, or plucking the hair you want removed anywhere from two to six weeks before your appointment. A day prior to your session, shave the area where you wish to have hair removed so it’s easier for the laser to reach the follicles.
- Stop tanning (including self-tanner lotions and tanning beds) entirely the month before your treatment. Lasers are attracted to pigment in both the hair follicles and the skin, so avoiding skin tone changes helps lower the risk of burns.
What should you expect during LightSheer laser hair removal?
- Your provider should start with a patch test, to make sure your skin doesn’t have a negative reaction. If you’re particularly sensitive, let your provider know so they can apply a topical numbing cream prior to the session.
- During treatment, the laser emits a concentrated beam of light to damage the hair follicle and prevent regrowth.
- While your provider methodically treats one small area at a time, you may feel mild discomfort, like a warm pinprick or snap, as the laser passes over your skin.
- You may notice a bit of redness and swelling immediately after treatment, but that should fade within a day or two. Ice packs and anti-inflammatories can help keep swelling down.
Is the LightSheer laser safe?
- This FDA-approved laser is safe for both facial and body hair removal. “The LightSheer diode laser system’s design provides for enhanced comfort during treatment, minimal risk of infection, speed and accuracy” (realself.com, 2023).
When will you see results from the LightSheer laser?
- As with other hair removal treatments, you’ll need multiple sessions to see results. “Usually 20% of hair is removed with each treatment,” says Dr. Hooman Khorasani, a dermatologist in New York City. “Treatments are repeated every six weeks on the face and every 8 to 12 weeks on the body. This allows for effective removal of hairs in the anagen [growth] phase.”
- The hair in the treated areas will fall out gradually, in patches, the hair-free patches increasing in size with each session.
- Most people start to see results by around week three.
- Remember to keep out of the sun during your session schedule, wearing sunscreen if the lasered areas are exposed to sunlight.
