Darkening skin under bigger busts?

[Ashwin]

I have no idea what's causing this. Even after exfoliating and showering, I still see dark patches under my breasts. Is it just me or does a heavier bust contribute? Please let me know.

Is the skin texture velvety? It could be acanthosis nigricans.

Exfoliating can actually trigger more melanin. Try applying powder there every day after a bath – it reduces pigmentation caused by friction and sweat buildup. If you must use an exfoliator, go for a brightening roll‑on from the chemist. Don't skip the powder step; it works wonders.

I've seen similar hyperpigmentation linked to vitamin B12 deficiency. Have you had your levels checked lately?

It's usually due to sweat or a tight bra. Do you even wear a bra at home?

I noticed this after I started using a sports bra for the gym. Did you wear anything too tight and sweat a lot in it?

I'm a G‑cup ♀. I have some pigmentation under the breasts and consulted a dermatologist. He said it's mainly from constant friction of the bra band and sweating. He advised keeping the area as dry as possible and maintaining good hygiene. I also have acanthosis nigricans, but the doctor said that's mostly on my neck, belly and underarms – quite different from the darkening under my boobs.

Try not wearing a bra for a week and compare photos. If there's a visible change, your bra is likely the culprit.

It's quite common! I just apply my deodorant on the area after using it on my underarms – it keeps the skin dry and helps.

Since you're all here, could you suggest some brands where I can get cute bras for bigger busts?

I used to have this too. I started applying a roll‑on under my breasts after a bath and I don't wear a bra at home. Do you do sports or work out? Heavy sweating could be a cause, or if you have PCOS and insulin resistance, managing that can help reduce it.
