Skin Lightening + Shave Q&A

Over the years, my vulva, bikini line, and inner anal area have darkened due to shaving. Can this issue be alleviated?

I am very insecure about getting naked because of how dark my genitals look. I understand few ethnicity have dark genital but mine is very contrast to my body skin tone please guide me lighten it. Shaving makes it darker as well.

Does skin bleaching really work? If so, what brand would be recommended? Is there a laser treatment for this? If so, on average how many treatments are necessary?

Okay so I shaved my upper lip since I can remember 13 or 14 and now I'm 21 , over time it has look darker and I just hate hiding my face ; also couple months ago I wax the upper lip and I left it in for a little and I got a burn spot and I took care of it but it left a really noticeable dark spot so does anyone know what can I do ? Or any good cream to fix the problem
