How To Get Rid Of Dark Underarms

Did you know that almost 74% of the world’s population, irrespective of their race, culture and gender, have dark underarms? Armpit hyperpigmentation or dark underarms is a completely natural occurrence that affects people of all ages, genders and ethnicities. 

Though this condition is most often harmless, people tend to seek different ways to lighten this area of their body for aesthetic purposes. This blog will help you understand the causes of underarm pigmentation and help you  

What Causes Dark Underarms?

The darkening of the underarms as mentioned before is a common concern for many individuals and knowing the reason behind it is essential for prevention. Dark underarms occur because of various factors such as irritation, hormonal changes, genetics, lifestyle habits and even stress. 

Hyperpigmentation

Hyperpigmentation is a condition wherein there is an overproduction of melanin in the body. Melanin is the pigment which is responsible for the colour of the skin. Overproduction of melanin in the underarm area is extremely common and affects north of 70% of all adults. 

Post-Inflammatory Hyperpigmentation (PIH)

If your underarm area looks darker than usual recently and feels bumpy or irritated, you may be suffering from hyperpigmentation as a result of inflammation also called PIH. This condition occurs when the skin is irritated or damaged, which leads to an increase in the production of melanin to heal the skin. 

Aggressive shaving or waxing, which might cause small cuts or inflammation are the common culprits in being irritants in the underarm area, and can cause gradual darkening.

In this skin condition, there are dark, velvety patches in body folds, which include the underarms. This often is caused when there is insulin resistance in the body, obesity or hormonal disorders. 

People with this condition may notice thickening of the skin alongside darkening, particularly in areas such as the neck and groin. It can also be a symptomatic condition for more problematic underlying issues such as type 2 diabetes. 

Hormonal Changes

It is important to understand that hormonal changes play a significant role in skin pigmentation, and fluctuations in these levels during puberty, pregnancy or menopause can stimulate melanocyte activity, leading to an increase in melanin production. Polycystic Ovary Syndrome (PCOS) and conditions similar to that also cause hormonal imbalance, contributing to dark underarms.

Genetic Factors

Genetics can influence an individual's chances of developing dark underarms. People with darker skin tones and a family history of hyperpigmentation are more likely to develop this disorder. This hereditary propensity can make certain people more prone to darkening in regions like underarms, elbows, and knees.

Irritation and Friction

Daily habits like harsh shaving or waxing and wearing tight-fitting clothes significantly impact the appearance of underarm skin. Using shaving or waxing products that are irritant to the skin can also cause underarm pigmentation. Shaving with dull razors or lack of proper lubrication can lead to irritation and inflammation of the skin. Aggressive waxing can also exacerbate skin sensitivity which may lead to darkening over time.

Wearing Tight Clothing

Wearing tight-fitting clothes causes friction in the armpit area and this leads to irritation and accumulation of dead skin cells in the area. This buildup prompts the skin to become more pigmented, resulting in darkening of the armpits.

Irritating Products

Certain ingredients present in most deodorants and antiperspirants irritate sensitive skin. Allergic reactions or contact dermatitis is a major contributor to hyperpigmentation and this is caused by alcohol, fragrances and certain chemical products that are present in deodorants and antiperspirants.

Poor Hygiene Practices

Poor hygienic practices can lead to the accumulation of sweat, bacteria and dead cells in the underarm area. This accumulation causes skin irritation and darkening. Regular washing and exfoliating help in the prevention of this buildup and maintain an even skin tone.

Sun Exposure

Though the underarms aren’t typically exposed to sunlight, prolonged exposure can lead to hyperpigmentation. In addition to that, UV rays also stimulate the increased production of melanin and thus, protecting the underarms from excessive exposure to the sun is crucial for preventing further darkening.

Fungal or Yeast Infections

Fungal infections, like those caused by Candida, can lead to inflammation and darkening of the skin. This causes itching and scratching the affected area might also result in post-inflammatory hyperpigmentation, thus making the issue worse. It is essential to maintain good hygiene and address any infections immediately, therefore preventing further darkening.

Understanding the various causes of dark underarms is the first step toward effective treatment and prevention. By maintaining good hygiene, being aware of hormonal influences, and addressing irritants, individuals would be able to work towards maintaining even skin tone in the underarm area. 

If the dark underarm issue continues after these efforts, it is advisable to consult a dermatologist who would provide additional insights and treatment options that are suitable to the individual and their needs.

Role of Stress

Stress plays a vital role in the darkening of underarms and here are some reasons for how it does:

Increased melanin production

Stress triggers hormonal changes and this leads to an increase in the production of melanin which further leads to hyperpigmentation and darker skin in the underarm area. Hormonal fluctuations due to stress stimulate melanocytes, the pigment-producing cells in the skin. In times of biological stress, the Adrenocorticotropic hormone (ACTH) is secreted in the anterior pituitary gland, which triggers melanogenesis that produces skin pigmentation.

Weakening of the immune system

Chronic stress weakens the immune system, and makes the body more vulnerable to skin inflammation and infections. This irritation can then trigger post-inflammatory hyperpigmentation (PIH) and darkening of the underarms.

Unhealthy habits

Stress may lead to unhealthy habits like neglecting personal hygiene, or using harsh deodorants. These behaviours can directly contribute to underarm irritation and darkening over time. Stress and anxiety about dark underarms can become a vicious but breakable cycle. 

Self-consciousness may lead to avoidance behaviours like wearing long sleeves, which then makes the problem worse by preventing the skin from getting air and light exposure.

However, it's important to note that stress is not the sole cause of dark underarms. Genetics, hormonal disorders, medications, and other skin conditions can also contribute to hyperpigmentation in this area. Managing stress through relaxation techniques, therapy, and lifestyle changes may help prevent stress-related darkening, but consulting a dermatologist is essential in terms of dealing with PIH or infections. 

Is it Normal to Have Dark Underarms?

Yes, it is completely normal to have dark underarms for most people. The skin of the armpit is sensitive and is prone to various factors that can result in darkening. Though it is typically not a medical concern, it harms the self-esteem and body image of an individual, which pushes them to seek various treatments.

The Psychological Impact of Dark Underarms

While having dark underarms, an individual might feel various negative emotions such as embarrassment and self-consciousness, especially in social situations where sleeveless clothing is worn. This can have a psychological impact on one’s self-confidence and willingness to participate in activities such as swimming, or even wearing certain outfits. 

Understanding these feelings and addressing the issue is crucial as it highlights the importance of both physical and emotional well-being.
