The copper bromide dual yellow laser has proven to be effective in treating melasma. It is non-ablative, safe and does not cause injury to the outermost layer of the skin.
How Does It Work?
The yellow laser (578nm) inhibits VEGF (Vasculo-endothelial growth factor) which regulates the production of new vessels caused by sun damage. Controlling the underlying vascularity will reduce epidermal pigmentation. The yellow laser has also shown to be effective in reducing the size and number of vessels, and erythema (redness from UV damage) in the melasma lesions. This results in the breaking up and lightening of the treated areas of melasma.
The green laser light (511nm) will directly reduce epidermal pigmentation by fragmenting the epidermal melanin, causing the dark areas of skin to lighten.
