Laser hair reduction
A device-based treatment using targeted laser energy to reduce hair growth over a course of sessions, matched to skin and hair type for safety and effectiveness.
What it is & how it works
A laser (commonly Nd:YAG or diode, selected based on skin and hair type) targets melanin in the hair follicle with focused light energy, damaging the follicle's ability to regrow hair; because it targets hair in an active growth phase, multiple sessions are needed to catch follicles as they cycle through growth over time.
How it's done
Performed in-clinic after a skin and hair-type assessment to select the appropriate laser and settings; each session takes anywhere from a few minutes to about an hour depending on treatment area, typically in a course of 6–8 sessions spaced 4–6 weeks apart, with sun avoidance recommended before and after each session.
Why Unfold Longevity
Laser type and settings are matched to skin and hair type at assessment rather than a fixed protocol applied to everyone, reducing the risk of burns or pigmentation changes.
Well-established procedure with a strong safety record when laser type and settings are matched appropriately to skin tone and hair color; not effective on very light or grey hair, and higher risk of pigmentation change or burns if the wrong laser or settings are used for a given skin tone — assessed before treatment begins.
Related questions
Most areas need a course of 6–8 sessions spaced 4–6 weeks apart, since the laser only affects follicles in an active growth phase and hair cycles through growth over time; results are long-lasting but not always permanent, and occasional touch-up sessions are sometimes needed over the following years.
Yes, when the laser type is matched appropriately — Nd:YAG lasers, for example, are generally considered safer for darker skin tones than some diode or IPL systems. A skin and hair-type assessment beforehand determines the right laser and settings for your skin rather than using one setting for everyone.
