Laser Hair Removal

Miami Dermatology & Laser Institute offers laser hair removal targeting and destroying hair follicles for permanent hair reduction. Multiple laser devices are used depending on skin type and hair color, ensuring safe and effective treatment across all Fitzpatrick skin tones. Sessions vary in length by treatment area — from a few minutes for small facial zones to up to an hour for large body areas.

Laser hair removal at Miami Dermatology & Laser Institute is performed using medical-grade laser devices calibrated by board-certified dermatologists to the patient's skin phototype, hair color, and treatment area characteristics — a level of clinical oversight that significantly reduces the risk of adverse effects such as post-inflammatory hyperpigmentation or burns that can occur with less-supervised treatment settings. The biological mechanism of laser hair removal is selective photothermolysis: laser energy at wavelengths absorbed preferentially by eumelanin (the dark pigment in hair) — typically 755 nm (Alexandrite), 810 nm (diode), or 1064 nm (Nd:YAG) — is delivered in a precisely calibrated pulse duration matched to the thermal relaxation time of the hair follicle. This allows the follicle to absorb lethal heat energy while surrounding tissue remains largely unaffected. Follicles in the anagen (active growth) phase are most susceptible to thermal damage, which is why multiple sessions spaced four to eight weeks apart are necessary to achieve meaningful hair reduction — each session treats the currently anagen-phase follicles, progressively depleting the follicle population over a treatment course of six to eight sessions. For patients with darker skin tones (Fitzpatrick IV–VI), the clinic selects longer wavelengths (1064 nm Nd:YAG) with longer pulse durations to minimize the risk of competing melanin absorption in the epidermis. Results after a full treatment course typically represent 70–90% permanent hair reduction, with maintenance sessions occasionally needed for residual growth. Treatment areas range from small facial zones (upper lip, chin, sideburns) to large body regions (back, chest, legs, bikini area).
