Laser Hair Removal

Permanent laser hair reduction using medical-grade laser devices targeting the melanin in hair follicles, suitable for face, underarms, legs, bikini, and other body areas.

Laser hair removal at Astria Medical Aesthetics offers a long-term solution to unwanted body and facial hair, delivering permanent reduction with each treatment cycle. The clinic uses medical-grade laser devices calibrated to target melanin in the hair follicle's bulge region without damaging the surrounding skin — a process known as selective photothermolysis. The laser energy is absorbed by the melanin pigment within the hair shaft and follicle, generating heat that damages the follicular stem cells responsible for hair regrowth. Because hair follicles cycle through active (anagen), transitional (catagen), and resting (telogen) phases, laser hair removal is only effective during the anagen phase when the melanin content is highest and the follicle is most susceptible to thermal damage. Multiple sessions are therefore required to capture each follicle during its active growth phase. A typical course involves 6–8 sessions spaced 4–6 weeks apart for facial hair and 6–8 weeks for body areas. Maintenance sessions every 6–12 months are recommended after the initial course, as some follicles may reactivate over time due to hormonal changes. Suitable treatment areas include the upper lip, chin, sideburns, underarms, arms, legs, bikini line, Brazilian, back, chest, and abdomen. All laser hair removal procedures at Astria are performed or supervised by MOH-registered doctors, ensuring appropriate device settings for each patient's Fitzpatrick skin type — particularly important in Singapore's predominantly Asian population where skin types III–V require careful parameter selection to minimise the risk of post-treatment pigmentation changes. Cooling mechanisms protect the epidermis during treatment.
