Laser Hair Removal
What setting should be used in a Cynosure Elite machine Nd:Yag for type IV/V Indian skin?
The Cynosure Elite has two wavelengths, 755nm (alexandrite) and 1064nm (Nd: YAG), and for darker skin types like IV and V, the 1064nm is the safer choice. The longer wavelength bypasses melanin in the epidermis more effectively than the 755nm, so it targets the hair follicle with less risk of burns or pigment changes in richly pigmented skin.
That said, I can't give you a specific fluence or pulse duration number that applies universally. Settings depend on hair density, hair color, treatment area, and how your skin responds to a test spot, which any properly trained provider should do before a full treatment. Starting conservative and titrating up over sessions is standard practice with darker skin types, and it doesn't compromise long-term efficacy, it just protects against complications.
If you're being treated somewhere, ask the provider directly what settings they use for Fitzpatrick IV-V skin and why. If you're shopping for a provider, look for one experienced specifically with laser hair removal in deeper skin tones.
Clinical Context
For darker skin tones, Nd: YAG laser settings aren't one-size-fits-all — providers usually test a small area first and watch for redness or swelling before treating the full site. The energy level is then adjusted based on how your skin responds. Cooling the skin during treatment helps lower the risk of burns. Because dark or light spots can sometimes appear days after a session, treatments are spaced out so your skin can be checked before the next one.
