Long‑pulse laser
1. Overview
Our Long‑Pulsed Alexandrite Laser operates at a 755 nm wavelength, widely recognised as the clinical gold‑standard system for fast, comfortable permanent hair reduction. Based on the principle of selective photothermolysis, the laser energy is selectively absorbed by melanin within hair follicles, delivering controlled thermal damage to follicular germ cells while protecting the surrounding epidermis. It delivers efficient results for fine, light‑coloured and dense dark hair, ideal for clinics targeting light‑to‑medium skin tones (Fitzpatrick Skin Types I‑III).
2. Working Principle
The long‑pulse millisecond‑duration energy extends thermal retention inside the hair root, fully destroying follicular regenerative tissue without over‑heating superficial skin. Equipped with integrated contact cooling / dynamic skin cooling technology, the system lowers epidermal temperature before, during and after each pulse to minimise discomfort and reduce the risk of pigmentation changes. Adjustable spot sizes, pulse widths and energy fluence allow practitioners to customise parameters for different body regions, hair thickness and skin conditions.
3. Key Advantages
755 nm wavelength with high melanin affinity, excellent performance on fine hair and blonde‑dark hair
Large spot handpiece for fast coverage over large areas: legs, back, chest, arms
Adjustable long‑pulse duration for safe and precise clinical control
Built‑in skin cooling system for higher patient comfort, less pain and minimal downtime
Multi‑function capability: benign pigmented spot reduction alongside hair removal
Stable laser output, long service life, designed for high‑volume aesthetic clinic use
4. Clinical Applications
Primary Treatment：Permanent Hair ReductionTreatment zones: upper lip, chin, armpits, bikini line, legs, arms, chest and back.Secondary Indications：Superficial benign pigmented lesions such as freckles and solar lentigines.
Best suited for Fitzpatrick Skin Type I‑III; cautious parameter setting for Skin Type IV. For deeper‑toned skin, combine with 1064 nm Nd:YAG wavelength if your machine supports dual‑mode operation.
