Firstly, if you are worried about dark skin pigmentation in your armpit area, you should know that it is mostly completely natural. This is especially the case if you have naturally dark skin. The discoloration can be from heat, clothes, shaving and even simply the inevitable action of time on our bodies as we age.

There are medical reasons behind this condition. One common such condition is acanthosis nigricans. It is a hyperpigmentation of the skin and is fairly common, but not in acute cases. It is more to do with genetics or as a symptom of a separate condition, but lifestyle can play a part, mainly in terms of diet.

This is because acanthosis nigricans is affected by insulin levels in the body. If someone eats too much, the body can overproduce insulin. This can not only lead to acanthosis nigricans, but diabetes and other concerning health risks. If you want to lighten underarm skin, but think you have have a condition like this, a trip to the doctor is in order. If diabetes or cancer are risks, then treatment for these should begin. Otherwise lifestyle changes are in order.

If the cause is acquired rather than genetic, then we have these tips to help you out. Most are natural and can be used together with other treatments to help lighten skin.

Use lemon

Thanks to bleaching and astringent effects, lemon is one of the best solutions for underarm whitening. Squeeze a lemon and apply its juice daily before showering, as well as combating odor, lemon juice will also help reduce melanin and remove dead cells from your armpits. The reason for lemon working to lighten your underarms is due to its bleaching abilities.


  • Half a lemon
  • 10 gr baking soda
  • 1 tsp honey


Mix all the ingredients together and apply in circular movements on your underarms. Leave for ten minutes and rinse with water. Make sure you add honey to the recipe, as using lemon to whiten underarms can cause photodermatitis due to the acids found in this juice.

Use orange

Just like lemons, orange is also an excellent alternative to whiten dark skin pigmentation underarms. Like lemons, oranges have vitamin C which is great for your skin. It is a natural exfoliant which means it removes old skin cells, one common cause for discoloration. Once these dead skin cells are removed, the vitamin C doesn't stop there.

Vitamin C can help stimulate regrowth of skin cells and collagen. These will help build your skin back to strength as well as provide a remedy to lighten its tone. Finally, vitamin C is also thought to reduce melanin production. Melanin is the pigment which causes our skin to darken in the sun, but overproduction of melanin can lead to darkened skin under your arms.


  • 1 glass water
  • 1 Orange peel


You just have to add some water to the orange peel and make a paste and rub it on your armpits. Orange peel effectively helps to remove the dark color of the area. Although not as acidic as lemon juice, orange juice shouldn't be left on the skin for prolonged periods of time either. Depending on the type of juice, it can also tint your skin a little which is counter-productive when you want to lighten underarm skin.
