What can I do to get rid of dark elbows, knees, vagina darkness and dark thighs? Please help, any cream

For pubic discoloration, I would use a combination of Luminase creams + Exfolase lotion; plus once monthly light chemical peels. Best, Dr. Karamanoukian Los Angeles

I suggest peels and lightening creams for this.  although, there is no "cure" for this and it is often worsened with rubbing.  best, dr. emer.

A prescription bleaching cream such as Triluma® or even a prescription cortisone such as Topicort® may even out an area of hyperpigmentation on the body. Please consult a board certified aesthetic dermatologist for a consultation.
