Does Keratosis Pilaris, cause itchesness? How about exposure to sun and type of clothes to be worn/dye/etc?

Keratosis Pilaris is a skin condition usually found on the upper arms, buttocks and thighs. The skin cells that normally flake off as a fine dust from the skin form plugs in the hair follicles. These appear as small pimples that have a dry "sandpaper" feeling. They are usually white but sometimes rather red. They usually don't itch or hurt.





Keratosis Pilaris is particularly common in teenagers on the upper arms. In babies, it tends to be most obvious on the cheeks. It is usually worse during the winter months or other times of low humidity when skin dries out, and may worsen during pregnancy or after childbirth.
