[Skin Concerns] Hyper-pigmentation of sensitive areas

Hey guys! So I just saw a post about postinflammatory hyperpigmentation and read the side bar, but the marks are not on my face. I'm a Middle Easter/Italian female with light olive skin (I tan super easily though), and I get darkish purpleish tints in pubic areas and random places when I shave. I have dark peach fuzz all over my body, so I shave a lot in the summer. I thought it would get better with tanning but apparently it just gets worse...so

I was wondering if any of the products mentioned were ok for sensitive areas? Any advice would be much appreciated!! I'm super insecure about it :/
