Does anyone know whether tyrosine supplementation can exacerbate hyperpigmentation -- as in darkening of melasma, freckles, etc.? TIA!

I don't think so. Where is the hyperpigmentation? Phillipa

I have some very stubborn brown spots on my face. I think they are melasma from taking birth control pills for many years. (I no longer take them, but the spots are still there despite trying various products.) I know that tyrosine is involved in melanin production, but the science is above my head so I thought I'd ask you guys about it. It seems like my skin is even splotchier since I started dabbling with tyrosine, but I could just be imagining it. I definitely don't want to continue if it might be a possible side effect, though. I plan to research other dopaminergic alternatives for my apathy. Things on my list to learn more about are mucuna, TMG, NADH, and theanine. I might up my fish oil dose too, since I'm only taking 1200 mg now.

A study on mice concluded:
"Melanocytes were visible throughout the dermis and epidermis of the irradiated groups, whereas only scattered dermal melanocytes were found in the controls. It appears that oral or topical tyrosine did not enhance pigmentation present with or without irradiation, detected optically or histologically."
