Irritation and discoloration on and around the armpit area are common issues many people face. There are several factors that contribute to discoloration and irritation in that particular area. Having dark underarms can come from many things including your deodorant, hormones, medication, shaving, skin and/or medical conditions and more.
What Causes Underarm Discolorations:
1. Yes, discoloration underneath the arm can be caused by genetics. Acanthosis nigricans (AN) is a skin disorder that thickens and darkens the skin in certain areas. This skin disorder can be caused by underlying medical conditions such as obesity or diabetes.
2. Your deodorant could be causing irritation underneath the arms which can lead to a rash. When a rash occurs on any part of the body it will itch and result to one scratching the skin. The combination of applying toxin ingredients on the skin and scratching can cause dark armpits.
3. Shaving the armpits is how most people get rid of armpit hair and is the most common cause for discoloration. It is better to wax your armpits so that the hair underneath your arms is pulled from the root and not removed just form the surface.
4. Skin discoloration could also be caused by a hormonal imbalance experienced by women who are pregnant or taking birth control.
How to Improve and Prevent Discoloration:
1. Change your deodorant – some deodorants contain toxic chemicals such as aluminum that can lead to irritation and discoloration. Try using a natural deodorant.
2. Exfoliate and moisturized – the skin underneath your arms need love too. It is important to exfoliate and moisturize your armpits. Exfoliating at least 3 times a week will help remove dead skin cells from building up underneath the underarms. Moisturizing your armpits will heal and protect the skin.
3. Stop shaving – some people have experienced minimal or no discoloration when the hair underneath the arm is removed by waxing or laser hair removal.
4. Wear loose clothing – certain fabrics and soaps you use to wash your clothes can cause irritation to the armpits. It is important to let your underarm breathe.
