You may have a condition called keratosis Pilaris which is treated with exfoliants like prescription Salvax or Retin A.

Red blotches on the arms can be due to a variety of illnesses and skin conditions. The Mayo Clinic explains that keratosis pilaris can cause an excess buildup of the skin's protein, causing red, scaly, blotchy plugs to develop on the skin. Blotchiness may also be due to eczema or contact dermatitis, in which the skin reacts to substances such as soap or chemicals. Medical conditions such as Hughes syndrome can cause the blood to clot in the veins, giving the arms a blotchy appearance.
A physician can determine the cause of blotchy skin on the arms. He may suggest a medication or cream containing vitamin D, glycolic acid, lactic acid, tretinoin or urea to reduce the appearance of blotchiness. With keratosis pilaris, topical retinoids can help slough off the excess keratin causing blotchiness. To treat Hughes syndrome, a doctor may suggest the use of the medications heparin, warfarin and aspirin.
