best dermatologist in Kochi

As a dermatologist in Kochi, I often see young adults especially girls complaining of dark underarms. This dark pigmentation in underarms causes significant embarrassment to them and they feel uncomfortable wearing sleeveless clothes.

What are the causes of dark underarms?

  1. Genetics - It can be a part of constitutive skin colour.

  2. Allergies - If you have had allergies to products like deodorants or perfumes, the allergy would have left behind pigmentation.

  3. Trauma - Repeated trauma in the form of waxing and shaving of hairs can lead to skin inflammation and cause pigmentation.

  4. Obesity - If you are overweight, repeated friction in folds like underarms can lead to skin darkening,

  5. Acanthosis nigricans - This is a skin manifestation of a hormonal imbalance characterised by insulin resistance. It is a predictor of diabetes mellitus in the future. It can also be associated with Polycystic ovarian syndrome. (PCOS) What is the treatment of dark underarms?

The best treatment for dark underarms is to address the causative factors, lightening creams and mild chemical peels.

Creams with mild lightening agents like niacinamide, alpha arbutin, mulberry extracts, vitamin C can be tried to get good results. Avoid retinol without a consultation of dermatologist as it can irritating to the skin and can worsen darkening, Avoid alpha and beta hydroxy acid containing serums as they can further irritate the skin.
