Detailed answer

Corticosteroid creams are commonly used in managing eczema flare-ups due to their anti-inflammatory properties. They help reduce redness, itching, and swelling associated with eczema. These creams work by suppressing the immune response and reducing the inflammation in the affected skin. However, it's important to use them as directed by a healthcare professional, as long-term and excessive use can lead to side effects such as skin thinning and discoloration. It is recommended to use the mildest and lowest potency corticosteroid cream that effectively controls the flare-up, and to gradually reduce the frequency of use once symptoms improve. It's also important to moisturize the skin regularly and use other non-steroidal treatments as part of a comprehensive eczema management plan.
