Laser Hair Removal

Shine Dermatology uses the GentleLase alexandrite laser to deliver safe and effective permanent hair reduction. The system is optimised for lighter skin tones and targets melanin in the hair follicle, progressively reducing hair density over a series of sessions.

Laser hair removal at Shine Dermatology Clinic is performed using the GentleLase, a long-pulsed alexandrite laser widely regarded as the benchmark device for permanent hair reduction on lighter skin types. The procedure works by targeting melanin concentrated in the hair follicle with selective photothermolysis — destroying the follicle's growth capacity while leaving the surrounding skin unaffected. Dr Rajaratnam's dermatological background means each patient undergoes a thorough skin assessment before treatment begins. Fitzpatrick skin type, hair colour, and the density of the target area are all factored into the energy settings, pulse duration, and cooling parameters used. Hair grows in cycles — anagen (active growth), catagen (transition), and telogen (resting) — and the laser is only effective on follicles in the active anagen phase. This biological reality is why a course of six to eight sessions spaced six to eight weeks apart is required to intercept sufficient follicles over time. Common treatment areas include the underarms, bikini line, legs, arms, upper lip, chin, and back. Each session is relatively quick — smaller areas such as the upper lip may take under ten minutes, while the full legs or back require longer appointments. There is no downtime, and patients can return to daily activities immediately. Long-term hair reduction of 70–90% is a realistic expectation for most patients. Annual maintenance sessions may be needed as hormonal changes can occasionally reactivate dormant follicles. The clinic recommends avoiding sun exposure before and after treatment to minimise the risk of pigment changes.
