What is this ring-shaped rash on my skin?

Answered by the AskDoc Medical Team · Medically reviewed under our Medical Director, MBBS

A slowly expanding ring with a scaly, slightly raised border and calmer center is classic ringworm, a fungal infection, no worm involved, caught from skin contact, pets, gyms or shared towels.

An antifungal cream, terbinafine or clotrimazole, applied a centimeter beyond the edge twice daily for two to four weeks clears most. Steroid creams alone feed it while hiding it, a common trap.

Rings that resist a proper trial, involve the scalp, or multiply need a doctor; scalp fungus needs oral treatment. Not every ring is fungal, eczema and other conditions mimic it, which is why failed treatment means reassessment, not repetition.

For dry or itchy skin

Doctors reach for plain, fragrance-free creams like CeraVe or Cetaphil, not fancy actives. A thicker cream beats lotion, applied within minutes of washing while skin is still damp.
