Skin On Butt Area And Back Dry And Black. Why Does It Get Itchy? Moisturizer Helps. Start To Worry?
Thanks for posting your query.
I have seen the photograph and the symptoms seem to be due to dry skin or eczema skin.
It is a form of inflammation skin characterized by redness, skin edema (swelling), itching and dryness, crusting, flaking and cracking.
I suggest you to get the diagnosis confirmed from a dermatologist after examination. Steroids is one of the best treatment for eczema but it should be used only under medical supervision as it can cause skin thinning and atrophy. For the itching you can take antihistaminics like Benadryl or levocetrizine.
Follow these treatment options till you get an examination done from a dermatologist:
1) Avoid using soaps and harsh detergents which can dry the skin and deprive the skin of natural oils. Instead use a mild soap like Dove or colloidal oatmeal baths.
2) Avoid using products that may dry the skin such as powders or perfume.
3) Wear cotton clothes and change the underwear twice daily
4) Keep the area moisturized by using light emollients.
