What Causes Dark Underarms?
There are a number of reasons as to why dark underarms can occur. To make the right choice of treatment, the cause has to be identified first.
Shaving
Shaving is only removing hair on the surface, which will cause stubble to be visible and irritation over time. This itchiness may lead to the development of hyperpigmentation and make underarms look darker.
Friction from Clothing
When one wears tight clothes, there is continuous rubbing and irritation, particularly the underarm. This may cause production of melanin leading to dark under arms.
Use of Harsh Deodorants
Alcohol, fragrances or strong chemicals in some deodorants and antiperspirants irritate the skin and cause discoloration.
Poor Hygiene
Dark spots may appear when the underarms are not washed properly and frequently because of the accumulation of sweat and bacteria.
Medical Conditions
Some health problems such as acanthosis nigricans, diabetes, obesity and hormonal disorders can cause the darkening of underarms. These are a medical diagnosis and require a treatment.
How to Get Rid of Dark Underarms
And in case you have been wondering how to make dark underarms lighter then here are the best and dermatologist tested ways:
1. Topical Creams
Use creams containing niacinamide, kojic acid, retinoids or vitamin C. These components help decrease melanin production and give light pigmented skin in time.
2. Exfoliation
Use mild exfoliating scrub or exfoliating glove to exfoliate your underarm once or twice a week. This clears out the dead skin cells and avoids their build up which may result in the appearance of dark spots.
3. Chemical Peels
Peels containing glycolic acid or lactic acid can be used to exfoliate the skin and lighten it by dermatologists. Such treatments stimulate the turnover of cells and enhance the general skin tone.
4. Laser Treatments
Laser treatment has become one of the best ways to deal with dark underarms as it focuses on pigmentation of the skin and provides lasting effects in a few sessions.
5. Microdermabrasion
This exfoliating skin care procedure removes the top layer of the skin very gently and also makes the underarms appear lighter.
Prevention: How to Avoid Getting Dark Underarms
Dark underarms are half the challenge, but how to prevent it is the most important thing to keep your skin healthy and even-toned.
Use Gentle Hair Removal Methods
It is also an option to change to waxing, sugaring or laser hair removal which causes less irritation and prevents the occurrence of dark spots.
Choose the Right Deodorant
Look out for fragrance-free, alcohol-free and sensitive skin deodorants. Baking soda, arrowroot powder, or tea tree oil natural deodorants would be a good substitute as well.
Moisturize Daily
A healthy skin is hydrated skin. Apply a mild moisturizer to avoid dryness and irritation which may result to pigmentation.
Wear Loose, Breathable Clothing
Don’t wear tight clothing that will rub. Natural materials such as cotton should be used so that the skin can breathe.
Maintain Good Hygiene
Wash your armpits especially when you sweat. Wash with a mild soap in order to avoid the growth of bacteria and odor.
