Laser Hair Removal For Dark Skin
Light-based devices used in hair removal procedures are highly sensitive to color and melanin, which plays a crucial role in the treatment of ethnic skin. The contrast between the color of the skin and the color of the hair is lesser in dark skinned patients.
The practitioner’s experience and the right type of laser hair technology is a must have for successful treatment.
Hair removal lasers such as the long pulsed “YAG” lasers are specially designed to safely and effectively treat darker skin types by bypassing the surface of the skin. Dark skin should be treated with lasers that have longer wavelengths to avoid possible side effects because melanin is especially effective in absorbing shorter wavelengths.
Laser hair removal on dark skin people comes with greater risks such as pigmentation changes, scarring and keloid formation. Melanin is responsible for pigmentation in the skin that is called epidermal melanin. The concentration of epidermal melanin increases with the darkness of the skin.
The Nd:YAG laser is the only laser that is specifically designed for patients with dark skin types (V and darker on Fitzpatrick scale).
All studies show that Nd:YAG laser is efficient and safe with minimal side effects.
Studies show that hair reduction after the Nd:YAG treatment was excellent. After 3 months there was 50% hair reduction and after 12 months 70-90% hair reduction. This laser should be used on dark skin with lower influence and extended pulse duration.
Modern lasers often come with a skin cooling device. Active epidermal cooling minimizes the pain and side effects of laser hair removal treatment on dark skin.
