I had the same issue and so did my mom. I am 18 turning 19 in a few days and i took showers and cleansed it regularly. Right after i shower or bathe i would dry off and put baby powder on it to dry it up more. My boobs sweat alot i am a double d cup naturally and because of that sweat build up the dark spot came. the baby powder has helped.
I believe it's called tinea versicolor. That's definitely what I have based on the images I looked up on Google.
Moist and warm parts of the skin gets brown patches. Also itches at times.
Anyway, stay dry. Powder up. :)
Answer right here.
I have it too. It's humid and I constantly sweat.
I visited a doctor about 6 months back, who gave me a pill for fungal.
May have helped, but not sure because I keep getting sweaty.
I read in the below answers that zinc helps. In any case, I used medicated powder (Aiken) to help keep my skin dry. That really dried up the spots. The dark brown skin peeled off.
There's a light brown patch below it now, but it looks better and is obviously getting better.
I'm going to let the skin peel off naturally instead of scrubbing it since it does not seem ready yet.
Overall,it's a definite fix.
Apple cider vinegar!
It works within days!!!
Just put it on a washer/cloth and wipe it on area 2-3 times a Day!! It works so well!!
what you're describing is what i had when i was 13, i had high triglycerides and cholesterol and this makes dark spots appear behind your neck, ears, on your elbows knees and sometimes in between your breasts. Its called Acanthosis Nigricans, luckily by eating right the dark spots can go away completely.
how do I get rid of it . it's between my boobs and on my stomach now
