Why Is My Skin Darker In Some Areas?
By the eva team · · 2 min read
Skin colour naturally varies across the body, and friction, irritation or previous inflammation can sometimes leave an area darker. However, dark patches that also feel thicker or velvety especially around the neck, armpits or groin may be a condition called acanthosis nigricans. It is not dirt and should be checked by a healthcare professional because it can sometimes be linked with an underlying health condition.
1. Why Is My Skin Darker In Some Areas?
Some body areas can naturally look slightly darker than others. But if a new patch becomes noticeably dark, thick or velvety, it is worth paying attention rather than trying to scrub it away.
2. Notice The Colour And Texture
Acanthosis nigricans usually appears as darker, thicker skin that may feel soft or velvety. It often develops gradually in body folds and may be easier to recognise by texture as well as colour.
3. It Often Appears In Skin Folds
These patches commonly appear around the back or sides of the neck, under the arms or around the groin. They may also develop in other skin folds or around the knuckles.
4. It Is Not Dirt
A dark, velvety patch is not caused by being unclean, and vigorous scrubbing will not remove acanthosis nigricans. Scrubbing too hard may instead irritate the skin.
5. Insulin Resistance Is One Possible Link
Acanthosis nigricans can sometimes be associated with insulin resistance, which means the body is not responding to insulin as effectively as it should. The skin change alone does not confirm diabetes or another condition.
6. Look At The Complete Body Pattern
Tell a healthcare professional about other changes such as very irregular periods, persistent acne, increasing facial hair, scalp-hair thinning or recent changes in your health. These details may help them understand whether hormones or insulin resistance could be involved.
7. A Healthcare Professional Can Check The Cause
A healthcare professional can examine the skin and ask about your symptoms, medicines and health history. Depending on the pattern, they may recommend tests to look for an underlying cause.
8. Your Skin Is Not Something To Blame
Dark skin patches do not mean that you are dirty or have done something wrong. Avoid harsh scrubbing or unverified lightening treatments. Ask for medical advice so the skin and any possible underlying cause can be assessed safely.
