Melanization following Melanotan II therapy is accompanied by reduction in sun damage/response across a broad spectrum of wavelengths. Melanotan II helps a blond to tan while doing less harm to the skin. Synthetic melanocyte stimulating hormone therapy extremely helps those with red/yellow melanin/color. Darker skin types have a greater affinity for the peptide pigmentation hormones => weaker analogs (Melanotan I) can be used effectively for tan(able) skin.
