There psoriasis it is a condition in which the immune system "attacks" our body, "venting" with the skin, and generating red and scaly plaques. The condition usually arises on the elbows and knees, but psoriasis can appear anywhere, including the scalp, lower back, nails and even the genitals.

If these products don't help, ask your dermatologist whether or not you should try a prescription retinoid.

Red angiomas

Because pre-diabetics are more at risk for skin infections, they can develop various types of rashes and bumps. Granuloma annulare and eruptive xanthomatosis are common examples.

Beauty products

Finally, one reason why new red spots on the skin they are also the ingredients of the beauty products that are used, and in particular for hair care.
