If you go to an Asian grocer or cosmetic store they usually stock deodorants that are specifically for whitening armpits. They have all the whitening products for skin, face and the like.

I didn’t realise this was a thing but perhaps check with a skin aesthetician.

Just embrace your body! Everyone is different and I feel that everyone is always trying to be like a celebrity or someone else without seeing that they are beautiful just as they are! Embrace it

Thank you all for aharing your insights. I simply wanted to have nice armpits worthy of showing off like the celebrities.

Certain deodorants always seem to lighten my armpits over time.

Never tried any of those methods.

Why would you want to lighten your armpits? Genuinely interested, no judgement. (I can’t even be bothered shaving mine!)

I didn’t even know this was a thing lol .

Peroxide, baking soda and white vinegar mixed together into a paste. Rub it into the stained area, let it sit for 10 min then wash in hot water, works a charm!

This is perplexing to me. Can anyone explain why a person would want ti lighten their armpits?

It is probably a good idea to be a little cautious with any products and always patch test.

Intriguing, I have never heard of armpit whitening. Maybe check with a beauty clinic that specialises in this area for sound advice?

I would be tempted to try I mix of bicarb and lemon juice. It’s meant to be a natural whitener

lemon juice

If your armpits don’t get sunlight then the skin may become dark. I’m not sure if you’re referring to your skin, or the hair pigment showing through underneath.

Why do you want to lighten your armpits? I’ve never heard of this before, so it’s hard to make suggestions.

Lemon juice will lighten it yes, but it will probably sting and it will affect the pH balance of the skin. Why are you against commercial whitening products?

I would be careful not to irritate the delicate skin.
