Final answer:
Topical corticosteroid creams like hydrocortisone are used to reduce inflammation and alleviate the symptoms of seborrhoeic dermatitis. For unresolved acne or ringworm, visiting a dermatologist is recommended to receive potentially stronger prescription medications or to reassess and tailor the treatment if initial therapies are ineffective.
Step-by-step explanation:
In treating seborrhoeic dermatitis, topical corticosteroid creams such as hydrocortisone are commonly prescribed by healthcare professionals. Hydrocortisone is a synthetic corticosteroid that functions to reduce inflammation and alleviate skin irritation, itching, and rashes. It accomplishes this by diminishing the production of histamine, which is involved in the inflammatory response. However, corticosteroid creams typically address the symptoms rather than the underlying cause of dermatitis.
For conditions like acne that do not resolve with over-the-counter products, dermatologists might consider prescription medications, including stronger topical agents like retinoids, antibiotics, hormone treatments, and possibly even oral medications such as isotretinoin for severe cases. Furthermore, antifungal creams are effective against most common fungi causing ringworm. However, if an antifungal cream does not resolve the infection, it is essential to revisit the healthcare provider for further assessment and potentially different treatment options tailored to the specific fungus type.
