Aunt Vadge,

I want to ask why my vagina is suddenly black?

Hi Worried,

I suspect you mean the skin of your vulva has gone darker – and if so, please relax, because this is almost always completely normal and harmless. (There’s a rarer, serious kind I’ll mention at the end so you can tell them apart, but it’s very unlikely to be that.) For most people the skin of the vulva and around the genitals is naturally darker than the rest of the body, and it commonly deepens over time – that’s just how that skin works, and it’s especially common and normal in people with more melanin.

Hormones nudge it darker (puberty, pregnancy and the contraceptive pill all deepen genital pigmentation, the same way they darken nipples), friction does too (shaving, tight clothing or chafing can leave the skin a little darker afterwards), and so does plain time, since the vulva naturally changes colour across your life.

None of this needs ‘fixing’ – it’s a normal, healthy variation, not a flaw, and if you’re simply curious about it cosmetically there’s a gentle rundown on darker spots on the labia.

One thing worth a passing check: if the darkening is velvety and sits in the creases, that can occasionally signal insulin resistance or PCOS, so mention it to a doctor if you also have irregular periods or extra hair growth – otherwise it’s nothing to worry about.

And the serious kind of ‘black’, actual dead tissue, never comes quietly: it arrives with severe pain, a wound or ulcer, a foul smell, or fever. If you’ve got any of those, see a doctor straight away. But a painless change in colour, with everything else feeling normal, is just your skin being skin.

Best,
Aunt Vadge
