I think the reason why Gandy doesnt look shitskin even w tan is his body has a ratio of pheomelanin to eumelanin it does not cross.
I know sulphation, cysteine and tyrosinase all play a role in this. But i dont know how exactly and what variables can change it, i think if we found a way to not entirely stop melanogenesis but shift the pathway towards the pink pheomealnin rather than the black eumelanin, the outcome of skin tine would be much better. I think the so called tyrosinase inhibitors actually change this on a genetic transcription level, indians who use tretinoin for example for a long time actually end up w a somewhat tanned castizo skin tone
You can see from the chart the two pathways by which we change this ratio are:
Increasing glutathione or cysteine (prolly even MSM since it provides a sulfate group) which increases pheomelanin content
decreasing tyronsiane (doable w kojic acid, alpha arbutin, hydroq etc), cu 2 plus (not recommended as copper is vital for enzymatic processes) and TRP1 (again not sure how to, it seems to depend on zinc a lot which is funny as zinc and copper are for the most part antagonistic)
L tryptophan also plays a part, reducing tryptophan absorption through eating meals low in fernstrom ratio can be good
Progesterone lightens and estrogen darkens skin, with testosterone as well slightly darkening skin and hair. I think topical progesterone can also be a good canditate to shift biosynthesis away from eu melanin towards pheomelanin.
You can see Gandy has this pink hue here which cannot be any undertone except lycopene which is the only carotenoid that is darker than eumelanin, so it has to be the pink lighter form of eumelanin
this curry was on tret for 3 years (first pic is before) and his skin seems to have a higher pheo/eumelanin ratio
