Darkened armpits are a common problem. Reasons for the discolouration include genetics, shaving, dead skin cells, deodorants or anti-perspirants, friction with clothing, excessive sweating, medical conditions and hyperpigmentation. There are a few ways to treat these discolourations using natural ingredients. While many of these home remedies lack scientific support as to their efficacy, many consumers recommend these methods.
Hydrogen peroxide is a popular bleaching agent used in teeth whiteners, skin creams and hair dyes. For personal use, hydrogen peroxide is available in a 3 to 3.5 per cent solution. Stronger concentrations are available, but only for commercial use. Apply the hydrogen peroxide to the underarm area with a cottonwool ball once or twice a day.
Lactic acid is one way to exfoliate the skin and remove darkened areas under the arms. Lactic acid is found in dairy products like milk, buttermilk and yoghurt. By applying one of these substances to the skin, the dead skin cells are removed, thereby lightening the colour of the skin. Lactic acid is a popular ingredient in many skincare products because of its exfoliating abilities. Lactic acid also works on discolourations by fading them and creating a more even skin tone. Apply milk with a cottonwool ball or use your fingers to apply yoghurt. Leave on for 10 to 15 minutes before washing off.
Lemon juice is a natural bleaching agent used for centuries to lighten dark areas of the skin. The citric acid in lemons also gently exfoliates the skin, removing dead skin cells that may contribute to the discolouration. There are several ways to use lemons. Slice a fresh lemon and rub it over the armpit every day until you see results. Another option is to apply lemon juice with a cottonwool ball. For a stronger bleaching effect, add baking soda. Baking soda is also considered a lightening agent. Make a paste of the lemon juice and baking soda and apply to your underarms. Leave on for 10 to 15 minutes, then rinse off. Do this every day until you have the desired results.
