As any lady and you will get this answer ‘I have dark armpits or my armpits are dark and I wish I could whiten or lighten them’.  Truly, having mild black underarms or very dark ones can be particularly embarrassing and it might affect your confidence and how you dress as you try hard to hide your armpits. Most will want to avoid swimsuits as well as shirts that are sleeveless.


Why are my armpits dark? It is normal for anyone to wonder why his or her armpits or underarms are so dark or black and sometimes itchy. There are many reasons for not only underarm darkness but also dark inner thighs, groin, and even neck region. Some of the most common causes include

1. Dark skin under armpits after shaving

If you have darker colored armpit hair, expect this issue after shaving. The darkness is due to the appearance of your cut hair follicle which is just below your skin surface i.e. sub-surface hairs will appear dark. Sometimes, your underarms can be itchy if a sharp razor is not used.

If you have very dark ones due to shaving, consider plucking or waxing your armpit hairs. These two hair removal options will make the remaining hair less visible thereby reducing the dark appearance of your underarms.

Note: Even if you opted for waxing or plucking, just like shaving, some microabrasion will cause small wounds which darken and thus you will still have dark-colored armpits.  Permanent laser hair removal might be recommended.

2. Darkness due to dead skin cells buildup

Another is the accumulation of dead skin cells on the microscopic bumps on your skin. This accumulation can also cause dark spots. To solve underarm darkening due to dead skin cells accumulation, try exfoliating with products that have lactic acid for excellent results.

3. Deodorant and antiperspirant use

Some people have reported that some antiperspirants or deodorants they are the dark armpits cause and even reported change when they stop using them. Although rare, there could be a likelihood that some ingredients could cause dark skin under armpits. Try switching your current deodorant or antiperspirant.

4. Black underarms acanthosis nigricans (diabetes)

This is a medical condition that causes this issue as well as the darkness around the “groin, neck, elbows, knees, knuckles, or skin folds. Lips, palms, and soles of the feet” []. Your skin will have dark patches as well as be thick with a velvety texture.

Acanthosis nigricans affects men and women and it commonly occurs in darker-skinned people and the obese. Furthermore, it has been associated with “insulin production or to a glandular disorder” [] i.e. affects people who are pre-diabetic or diabetic or those who are likely to suffer from diabetes.

This problem also affects people with “Addison disease, pituitary problems, hypothyroidism, or those undergoing growth hormone therapy, using oral contraceptives or cholesterol medications containing nicotinic acid []. To deal with it, try lightening products with Retin-A, salicylic acid, alpha-hydroxy acids, 20% urea, glycolic acid or lactic acid.

5. Hyperpigmentation

Going on with causes, hyperpigmentation could also be responsible for your this problem on your underarms, inner thighs, groin, and neck areas. It happens when your skin produces too much melanin but rarely affects armpits. If hyperpigmentation is what causes armpit darkness, consider the various treatments, remedies, and creams for whitening or underarm bleaching we will discuss.

6. Bacterial Infection

Still on causes, erythrasma, a bacterial infection caused by Corynebacterium minutissimum that cause “reddish-brown slightly scaly patches with sharp borders. They may itch slightly. The patches occur in moist areas such as the groin, armpit, and skin folds” []. The infection is common “in warm climates. You are more likely to develop this condition if you are overweight or have diabetes” [].

Tropical erythromycin gel and antibacterial soap will help you deal with the problem. In extreme cases, you might need to take pills

7. During pregnancy

Some women suffer from this problem during pregnancy. This is due to a lot of hormonal changes that might increase melanin production especially estrogen that increase the production of melanocytes, cells that produce melanin. Dark armpits while pregnancy is a periodical problem that causes not only uneven skin tone but also dark skin underarms, on your nose and on your upper lip. The discoloration normally goes away after pregnancy.

However, to some people, the hyperpigmentation due to pregnancy persists. On how to whiten them during this time including darkness on, upper lip or nose due to pregnancy, try the various home remedies, treatments and creams we are going to discuss afterward.

8. Tight clothing, too much rubbing, and friction

If our underarms are always rubbing against something, hyperkeratosis or skin thickening might occur as a means of body prevention against the rubbing irritation i.e. post-inflammatory hyperpigmentation. This often comes with hyperpigmentation. Wear loose and smooth clothing to reduce contact, rubbing and stains on clothes.

To avoid changes in bacterial growth, go for absorbent clothing avoiding synthetic ones since they will not absorb sweat. Your armpits are supposed to be dry. Try lotions with tretinoin (found in Retin-A) as well as “oral medications, such as isotretinoin, and dermabrasion, which may help to reduce the thickness of the affected skin” [].

9. Other reasons 

  • Armpits scratching – After shaving, waxing or plucking your underarms, your underarm skin might be itchy and encourage pleasurable scratching which might discolor your armpits.
  • Overweight – as already mentioned, obese or overweight people tend to suffer from this problem due to acanthosis nigricans, bacterial Infection or even underarm friction.
  • Fungal infections especially when the darkening of your armpits occurs with some mild itch
  • Some medications have been found to cause skin color changes including contraceptive
  • Excessive exposure to UV light encourages melanocytes cells to produce the melanin that will make your skin dark-colored.
  • Trauma, scarring, and injuries on underarm
  • Genetic factors

These are the main cause. The question “why are my underarms dark” should by now be fully and comprehensively answered. It is time to look at how to deal with this problem. Before trying any of the underarm skin whitening remedies, treatment or cream, ensure you know the cause. Otherwise, you might be treating a wrong cause where you are likely to fail.

How to reduce, get rid, cure, treat, fix, eliminate, clear, lighten or whiten them mean the same thing; solutions, attempts and ways to try to minimize or diminish the dark skin appearance in your armpits.  We are going to discuss the various ways to get rid of dark underarms in three broad approaches which will be the use of underarm whitening creams, natural or home remedies as well as other cures and treatments options available.

To clarify, most the ways can also be used to get rid of dark knees, groin area, neck area, inner thighs or as well as other body parts. Similarly, men and women can use these methods since they do not gender-specific. The specific treatment you chose might be dependent on what causes black underarms.

With bleaching cream

Understating the philosophy behind creams for skin whitening and for this case underarm bleaching cream is paramount in ensuring successful usage and obtaining desired results. Any good armpit whitening cream should not only eliminate darkness but also prevent it from happening by controlling melanin production i.e. “skin pigment is ultimately produced based upon the actions of the enzyme tyrosinase which catalyzes the chemical production of melanin. Shut down tyrosinase activity and you prevent further discoloration from forming” [].

Do they work or what to look for

There both prescription-strength creams as well as over the counter whitening creams which can be used to lighten, whiten or bleach them.

To tell if a certain cream will be effective, look at its active ingredients. Some of the active ingredients should include hydroquinone, steroids, retinol (common in Retin A), tretinoin (helps in exfoliation process, gets rid of already formed pigment in epidermis), hauronoside (found in mitracarpus scaber extract and prevents tyrosinase action), and arbutin (found in bearberry extract or uva ursi leaf extract and it inhibits tyrosinase activity). Arbutin and hauronoside are the two sister molecules of hydroquinone that works similarly.

As of now, “FDA only recognizes hydroquinone as a “bleaching agent”. That means that many other ingredients incorporated into products must be referred to as lighteners, brighteners or whiteners” []. Other ingredients that might be helpful include

  • Alpha hydroxy acids (especially lactic acid-glycolic acid that help in cellular exfoliation),
  • sutilains – betters penetration of ingredients that reduce melanin),
  • Melatonin – lightens hair follicles
  • Kojic acid – inhibits tyrosinase activity and “melanocytes treated with kojic acid additionally lose their dendrites which reduces the ability of these cells from passing on any residual pigment onto the keratinocytes” [
  • Paper mulberry -inhibits tyrosinase activity
  • Azelaic Acid – acts only on the highly active melanocytes
  • Vitamin C – reduces melanin formation as well as work as antioxidants
  • Gluconic Acid – as a chelating agent, it binds with copper molecules that would instead be used to activate tyrosinase enzyme
  • Licorice extract – has glabridin that stops the activation of tyrosinase
  • Beta Carotene – found in carrot oil and blocks tyrosinase receptor
  • Dithiaoctanediol – prevents tyrosine activation from being sugar-free whereas sugar molecule is required for tyrosinase enzyme activation.

When using skin bleaching creams or underarm bleaching cream, apply them on the area with darkness only and not nearby areas that might have lighter tones since they will be lighter and discontinued ones you have achieved the effect you wanted. Most underarm bleaching creams require longer usage, typically up to 6 months for results to be seen.
