810nm Diode Laser Hair Removal

810 nm diode laser hair removal at Sona Medical Aesthetics in Newcastle, WA, targeting melanin in the hair follicle for long-lasting hair reduction across face and body areas. A series of six treatments spaced six weeks apart is recommended to address hair in all growth cycles. Suitable for most skin types. Mild redness in the treated area typically resolves within a few hours.

Sona Medical Aesthetics offers 810 nm diode laser hair removal as a long-lasting hair reduction solution targeting a broad range of facial and body areas. The 810 nm wavelength sits in the near-infrared spectrum and is selectively absorbed by melanin in the hair follicle's bulb and bulge regions, generating heat that disrupts the follicle's ability to produce new hair growth. The 810 nm wavelength provides an effective balance between melanin absorption (allowing adequate energy uptake in the follicle) and depth of penetration into the dermis where the follicular bulb resides, making it the most widely used wavelength for laser hair removal across a range of skin tones. Because the laser only affects follicles that are in the active anagen growth phase at the time of treatment — in which the hair shaft contains the highest melanin concentration and is most directly connected to the follicular blood supply — a single session cannot address all follicles in a given area simultaneously. Each body area has a different proportion of follicles in anagen at any given time and a different hair growth cycle duration; the standard protocol of six sessions spaced six weeks apart is designed to intercept successive cohorts of follicles cycling into anagen across the full treatment course, achieving progressive reduction with each session. Common treatment areas at the clinic include the face (upper lip, chin, and sideburns), underarms, bikini and Brazilian line, legs, arms, and back. A built-in cooling mechanism in the diode handpiece chills the skin surface during energy delivery to reduce discomfort and protect the epidermis from thermal injury. Post-treatment mild redness and follicular swelling (perifollicular erythema) in the treated zone typically resolves within a few hours. Maintenance sessions once or twice a year may be recommended after the initial series.
