Laser Hair Removal

REGEVITA offers precision laser hair removal using targeted laser radiation to selectively destroy hair follicles at the root while leaving the surrounding skin intact. The procedure exploits selective photothermolysis — the principle that melanin in the hair shaft and bulge region absorbs laser energy at specific wavelengths far more efficiently than the surrounding dermis. When the laser pulse duration is shorter than the thermal relaxation time of the follicle, the absorbed energy heats and ablates the germinal matrix cells responsible for hair regrowth without spreading thermal damage to adjacent tissue. The treatment is suitable for a range of body areas and skin tones when matched to the appropriate laser wavelength, and produces cumulative, long-lasting hair reduction with each session.

Laser hair removal at REGEVITA is administered by the clinic's qualified therapist team and uses laser radiation calibrated to the principle of selective photothermolysis — a mechanism where chromophore-specific wavelengths deliver energy precisely to pigmented hair follicles while sparing the surrounding tissue. Melanin, the pigment that gives hair its colour, absorbs light most efficiently at wavelengths in the 755 nm (alexandrite) and 800–810 nm (diode) range; at 1064 nm (Nd:YAG), penetration depth increases, making the technique suitable for darker skin tones or deeper follicles in coarser hair. During the session, a chilled applicator is moved across the treatment area in a systematic pattern to ensure complete coverage. Each laser pulse — lasting milliseconds — delivers energy that is preferentially absorbed by the melanin in the hair shaft, conducting heat into the follicle's bulge and bulb regions. If the thermal damage threshold of the germinal epithelial cells is exceeded, the follicle loses its regenerative capacity and the hair does not regrow. Because only follicles in the active growth phase (anagen) are susceptible to photothermolysis at any given moment, multiple sessions spaced 4–8 weeks apart are required to catch successive cohorts of follicles cycling into anagen. Typical body areas treated at REGEVITA include the upper lip, chin, underarms, bikini line, legs, back, and chest. The treating therapist adjusts fluence (energy per cm²), spot size, and pulse duration based on the patient's skin phototype (Fitzpatrick scale) and hair coarseness at the pre-treatment consultation. Cooling gel or an integrated contact-cooling system maintains epidermal temperature and minimises discomfort during the procedure. Post-treatment instructions include avoiding sun exposure and tanning for two to four weeks, not waxing or plucking between sessions (shaving is permitted), and applying SPF 50+ to treated areas when outdoors. Contraindications include active skin infections, use of photosensitising medications, very recent sun exposure, and certain pigmentary conditions. Permanent hair reduction of 70–90% is achievable over a full course; occasional maintenance sessions may be needed annually for hormonally active areas.
