Contact dermatitis is a localized rash or irritation of the skin caused by contact with a foreign substance.
Inflammation of the affected tissue is present in the outermost layer of skin and the outer dermis the layer beneath the epidermis.
Contact dermatitis takes days to fade away. Even then, it fades only if the skin no longer comes in contact with the allergen or irritant.
It results in large, burning, and itchy rashes, and these can take anywhere from several days to weeks to heal.
The Soften Skin Soap / Psoriasis Soa and any of the psoriasis moisturizers would be helpful.
We also suggest changing your laundry detergent and fabric softeners to a natural brand as these can affect dermatitis.
