So many people have this problem. Some like it, but most hate it. Maybe you too. Maybe you question, “Why are my pits get darkened?” Well, actually, there are at least five different reasons your armpits could be darker than they should be.
(1) Shaving factor
When you shave your armpit, you cut the hairs off at, or just below, the surface of the skin. If your underarm hair are slightly darker than your skin color, they can give the appearance that your skin has a dark stain when it`s really just sub-surface hair.
Solution? Stop shaving and try waxing or plucking instead so you get rid of the hair below the skin surface. Since the hair isn’t lurking so close to the top of your skin, they won’t be as visible.
(2) Buildup of dead skin cells
According to some dermatologists, the dark spots under your arms are the result of dead skin cells that are trapped in microscopic “hills and valleys” on your skin.
Solution? Exfoliate, preferably with a product containing lactic acid.
(3) Antiperspirant and deodorant usage
In theory, some ingredients in these products (perhaps the fragrance) could be reacting with the skin to cause discoloration. Practically speaking, this seems unlikely, but many people do claim that when they stop using APDs, the darkness goes away.
Solution? Try switching brands or using a deodorant instead of an antiperspirant. You may stink a bit more, but hey, the Left Brain lives for experiments like that!
(4) A medical condition called acanthosis nigricans
This condition causes light-brown-to-black markings on the neck, under the arms, or in the groin. It can be related to insulin production or to a glandular disorder and it typically occurs in people who are overweight.
Solution? Watch your diet to control insulin production and use Retin-A, 20% urea, alpha hydroxyacids, and salicylic acid prescriptions to lighten your armpits.
This condition causes your skin to produce excess melanin pigment. It doesn’t usually affect armpits, so it’s a less likely cause.
Solution? Use a skin bleaching cream to destroy the excess of melanin. The Beauty Brains don’t recommend this unless you consult a dermatologist first. You can also try laser treatment to destroy the pigment.
