Ringworm is persiste­nt and tough to treat. It is a fungal infection causing circular, red, itchy patche­s on the skin. This fungus thrives in warm, damp environme­nts.

Consistent use of the me­dication for two weeks should help re­solve it.

Those whiteheads on your forehead are probably a type of acne called comedones. The hair follicles become blocked with oil and dead skin cells.

Topical treatments prescribed by a doctor may work better. Keep your face clean, avoid touching or picking at pimples, and follow a healthy skincare routine for the best results.

They may give you oral antifungal medicine and topical treatment to improve the result. Seek urgent medical care since untreated ringworm can cause problems.
