Dry cracked skin behind the ear: what to know

The fold behind the ear is exposed to shampoo, hair products, spectacle arms, mask straps, sweat, and friction. Repeated dampness followed by drying can weaken the surface and create painful fissures. Atopic dermatitis commonly presents with itchy, dry, inflamed skin, while Psoriasis can produce thicker, sharply defined scale that extends beyond the crease. Cracked skin may sting when washed or bleed after scratching; its appearance alone cannot identify the cause.

Rinse away fragranced products and pat the area dry rather than rubbing it. Apply a bland, fragrance-free ointment or cream to the outer skin after washing and whenever tightness returns; see Emollient Therapy for the role of moisturising treatments. Avoid picking scale, cotton buds in the crease, and newly introduced hair or skin products. Keep mask straps, glasses, and headphone arms from rubbing the sore area. If the skin repeatedly splits, a clinician can check for eczema, psoriasis, contact irritation, or another problem and tailor treatment.

Arrange medical assessment if cracking persists, spreads, keeps returning, or interferes with sleep or daily activities. Seek prompt care for increasing warmth, swelling, pus, a spreading red area, fever, or marked pain, because these can signal infection. Get urgent help if swelling involves the ear canal or face, hearing changes appear, or you feel seriously unwell.

Ask whether the crease looks more consistent with contact irritation, Atopic Dermatitis, Psoriasis, or infection; which moisturiser is suitable for this thin area; and whether any hair, eyewear, or hearing-device product should be paused.
