At G16 Lotion, we provide the best treat dry skin at home. Psoriasis is a fairly common skin disease marked by red, itchy, scaly patches. Psoriasis occurs when skin cells are replaced more quickly than usual. It is usually found on the elbows, knees and scalp but can affect other areas of the body. It tends to appear as red or pink small scaly bumps that merge into plaques of raised skin. For more information, visit our website.
