**Core Concept**
The management of eczema involves a combination of topical treatments, systemic medications, and lifestyle modifications to reduce inflammation, prevent flare-ups, and promote skin barrier repair. Eczema, also known as atopic dermatitis, is a chronic skin condition characterized by dry, itchy, and scaly skin.

**Why the Correct Answer is Right**
Topical corticosteroids are effective in managing eczema by reducing inflammation and itching. They work by suppressing the immune response, specifically by inhibiting the production of pro-inflammatory cytokines and reducing the expression of adhesion molecules. This leads to a decrease in skin thickness, scaling, and erythema. Topical corticosteroids are available in various potencies, from mild to very potent, and are often used as first-line treatment for mild to moderate eczema.

**Why Each Wrong Option is Incorrect**
**Option A:**
*Incorrect because* topical antihistamines are not effective in managing eczema, as they do not address the underlying inflammatory process.

**Option B:**
*Incorrect because* oral antibiotics are not typically used to manage eczema, unless there is a secondary bacterial infection. Antibiotics do not address the underlying inflammatory process of eczema.

**Option C:**
*Incorrect because* oral corticosteroids are not typically used to manage eczema, due to their potential side effects and the risk of skin thinning and rebound dermatitis.

**Clinical Pearl / High-Yield Fact**
Topical corticosteroids come in various potencies, and it's essential to choose the right one for the severity of eczema. The potency of topical corticosteroids is typically classified as mild (Group I), moderate (Group II-III), or potent (Group IV-VI).

**Correct Answer: C. Oral corticosteroids are not typically used to manage eczema.
