Whilst also being antibacterial and an antiseptic, lemon also is a natural bleaching agent and it can be used for a variety of tonal issues involving the skin, however it can result in some dryness. You can either apply the juice of a fresh lemon or use a slice to rub on the skin, and then leave for 10-15 minutes, at which point the skin should have dried. Rinse clean and then moisturize to prevent dehydration.

For a better exfoliator try sprinkling a wedge of lemon with sugar before scrubbing under the arms on the dark patches. This act should be repeated a few times a week.


Cucumber also acts as a natural bleaching agent for the skin and aids with lightening the pigment. Extract the juice from a cucumber by squeezing or grating before applying to the skin of the underarm and leave until dried. This should be repeated once or twice daily for the best results.

Another option is to mix the cucumber juice with an equal amount of lemon juice and turmeric. Apply this to the affected areas and leave for 30 minutes before washing. This should be repeated once a day until a noticeable improvement occurs.

Another potent and natural exfoliator, baking soda is a skin care staple for many. Make a paste from baking soda and water before applying to the underarm and leaving for 15 minutes before washing.

Treatment For Medical Conditions

There are some medical conditions which need a more potent treatment than using natural or herbal remedies. High insulin levels, obesity, diabetes and hyperpigmentation are a few of the well-known illnesses that can have an impact on underarm skin color. In addition, a buildup of deodorant or excessive sweating can also result in dark patches under the arm.

These more severe conditions can be treated using chemical creams or ointments which are devised specifically for combating this ailment. The creams contain chemical bleaching agents used to lighten skin tone as well as other active ingredients such as retinoid, hydroquinone and mercury.

These creams generally work on the premise of stunting melanin production and should not be used for more than 6 months continuously.

Other Options For Lightening Underarm Skin

Waxing / electrolysis

The use of shaving or depilatory creams is one of the more common causes of dark underarm skin. You could opt for waxing which removes the hair from the root and therefore ensures that you need to shave less frequently, or a more permanent measure would be to try electrolysis.

Sandalwood With Rose Water

By using a paste made from sandalwood and rose water on the underarm skin you will see a natural and aromatic alteration in the tone of the skin. The lightening properties in both rose water and sandalwood are very potent but also don’t need to be rinsed away either!

Whitening Scrub

The accumulation of dead skin cells can darken the underarm skin so the most efficient way to cure or prevent this is to exfoliate. Ensure that you are very gentle and use a sensitive scrub as the underarm skin is quite delicate.

Deodorant Use

Over use of deodorant, especially alcohol-based ones, can create dark patches. If you are prone to the darkening of underarm skin, try a more natural deodorant remedy such as alum or anti-fungal powders.
