Identify one potential side effect of topical corticosteroids.

Topical corticosteroids are commonly used in dermatology to treat a variety of inflammatory skin conditions, such as eczema and psoriasis. One important potential side effect of these medications is skin thinning, also known as skin atrophy.

This occurs because corticosteroids suppress cellular functions in the skin, diminishing the proliferation and turnover of skin cells. Over time, this leads to a decrease in the dermal layer's thickness and weakening of the epidermal structure. Skin atrophy can manifest as a more translucent appearance, fragility, and an increased susceptibility to bruising and injury.

The risk of atrophy is particularly pronounced with high-potency topical corticosteroids, prolonged use, and use on sensitive areas of the skin, such as the face and genitals. Understanding this side effect is crucial for practitioners to ensure they use these medications judiciously and monitor patients for any signs of adverse reactions.
