Causes of Dark Underarms
You might know that your skin color is determined by melanocytes, which are nothing but pigment-producing cells of your body. Now, when these cells multiply, they end up causing the skin to darken. As you would have likely guessed, melanocytes are the primary culprits of dark underarms.
Generally, people with darker skin are more prone to developing dark underarms. Genetics also play a part. A condition called acanthosis nigricans (AN), which often leads to dark underarms, may run in families. A faulty gene inherited from a parent or close relative can increase the risk. Hair removal methods like shaving or plucking can irritate the skin. This can trigger melanocyte overproduction and lead to darkening.
People who are obese or have excess weight are usually prone to dark underarms. They have high resistance to insulin. High insulin levels can stimulate melanocyte activity, leading to dark patches. So, people with type 2 diabetes also have higher chances of having dark underarms.
People who are obese and have conditions like Type 2 Diabetes, PCOS, Cushing Syndrome, Acromegaly, and Hypothyroidism are all at high risk for dark underarms. Because all the conditions disrupt insulin or hormone levels, which results in skin darkening. Some medications that increase insulin levels, like corticosteroids, birth control pills, and high-dose niacin also increase the chances of dark underarms.
Tips to Prevent Dark Underarms
Here are some handy tips you can try at home to avoid dark underarms:
- Always use a lubricant, such as shaving cream, before shaving your underarms. Replace your razor frequently. This will help minimize the risk of cuts and irritation. After shaving, apply a moisturizer or soothing lotion. This will keep your skin hydrated and calm.
- Use a chemical exfoliator once a week to gently remove dead skin cells and prevent buildup. Avoid harsh mechanical scrubs with coarse particles. They can easily cause micro-abrasions which can lead to irritation and ultimately darkened skin.
- Opt for breathable fabrics, especially during summer, to reduce friction and sweating in the underarm area. Avoid tight or abrasive clothing that can irritate the skin.
- Carefully choose deodorants or perfumes. They should avoid those containing pore-clogging ingredients. This primarily includes aluminum or irritants like alcohol. For sensitive skin, opt for mild and moisturizing options.
Treatments for Dark Underarms
Here are some of the different ways to treat dark underarms:
Lifestyle changes
Shedding excess weight can improve the condition, as it reduces skin folds and friction. Additionally, weight loss can help manage or prevent diabetes, which may also contribute to skin pigmentation issues in your underarm. Consult a nutritionist for personalized diet and fitness strategies to achieve a healthy weight. If you suspect that a medication you’re taking is causing dark underarms, speak with your doctor about alternative options. Switching to a different medication might alleviate the issue.
Natural Remedies
Some natural remedies are often suggested for lightening pigmented skin. These include sea cucumber extracts, curcumin, and milk thistle extract.
Dermatological Procedures
1. Chemical Peels
Chemical peels utilize exfoliating acids to remove the top layer of damaged, pigmented skin. For instance, AHAs (e.g., glycolic acid, lactic acid) are water-soluble acids that target surface-level skin, promoting cell turnover and revealing smoother, lighter skin underneath. AHAs also hydrate the skin, making them ideal for sensitive areas like the underarms. Similarly, BHAs (e.g., salicylic acid) are oil-soluble acids that penetrate deeper into the pores, removing excess sebum and debris. BHAs are especially beneficial if darkening is associated with clogged pores or acne. Regular treatments help even out skin tone and improve overall skin texture.
2. Microdermabrasion
This physical exfoliation technique involves removing the outermost layer of skin to reduce pigmentation. It is a gentle procedure that uses tiny crystals or a diamond tip to slough off dead skin cells. This is ideal for mild pigmentation issues and can be done with minimal discomfort and downtime. It helps improve skin tone and stimulate the growth of new, healthy skin cells.
3. Laser Therapy
Laser treatments target and break down excess melanin in the skin, which is responsible for pigmentation. By using specific wavelengths of light, laser therapy effectively reduces dark patches without damaging the surrounding skin. It also promotes collagen production and skin regeneration, which can further enhance the appearance of the underarm area. Laser therapy is particularly useful for addressing stubborn pigmentation that doesn’t respond to topical treatments or exfoliation.
Each of these treatments should be performed under the guidance of a dermatologist to ensure safety and optimal results.
