"Just surface-level cosmetic stuff that is better off not being left up to the scalpel jockeys, such as eye color, hair color, skin color and pigmentation, nipple color, and we are trying to find a generic sequence for nail color too. We did by chance stumble across something that can alter the flavor of the milk in lactating women, but it can't induce it like that one Mod can."
"Aa for how long the effects last, it depends on a few factors such as age and type of cosmetic mod being used. The one for hair color takes a few months to produce a noticeable color shift as it requires the follicles to first shed the old hair before a new one can take its place. The process can be sped up with hair growth mods but those have their own set of complications so I wouldn't recommend them unless necessary."
