What other skin conditions could be causing a tight, dry, and darkened rash around my nose that has not responded to anti-fungal pills, steroid creams (like Emusone M, Sebifin plus, and Desonide lotion), or a five-month treatment for suspected seborrheic dermatitis using ITSASPOR-200, ISOTROIN 10mg, and SEBIFIN PLUS CREAM, and are there any specific medical tests that can help find the exact cause?
Since antifungal and steroid creams (like Desonide and Emusone M) haven't helped, other possibilities include perioral dermatitis (which can actually be worsened by steroids), contact dermatitis, or rosacea. To find the exact cause, a dermatologist can perform a skin biopsy or a patch test to check for allergies. Please don't lose hope; a fresh evaluation and a targeted test can help us find the right path to heal your skin.
