Dry (or ashy) skin is very common and can be triggered by harsh soaps, fragrances, cleaning products, clothing, dry climates, genetics, health conditions, or medications. Luckily, over-the-counter moisturizers usually work really well.

Stasis dermatitis (venous eczema) is common in older adults. It causes dry, itchy skin on the shins, ankles, and tops of the feet. Weak leg veins and swelling stretch the skin, leading to eczema. Treatment focuses on compression, leg elevation, moisturizing, and topical medications.

Ringworm is a fungal rash that can be itchy. It usually comes from another person (often athletes) or an infected pet. It starts as a single, ring-shaped spot that grows over time. Most cases improve with over-the-counter antifungal treatments.

Tinea versicolor is a common yeast rash that usually doesn’t itch but can change your skin’s color. It’s more common in hot, humid areas. Treatment often includes antifungal creams or dandruff shampoo.
