Dark skin black female. I take care of my skin, but it's two-toned. Is there anything I can do to even out my skin tone from head to toe? OTC?

Get more tan? Bleaching is usually not the good option for evening out the skin tone but perhaps more tanning may help if you do not mind having an even darker skin. If you do not want to go the tanning route, I wonder if a spray-tan may be helpful. I presume that the lighter parts of your skin is not totally white since vitiligo is considered an autoimmune problem.
