What side effect of corticosteroids is characterized by fragile skin and easy bruising?

Corticosteroids are known to cause a variety of side effects, one of which is thinning of the skin. This occurs due to the catabolic effects of corticosteroids on skin collagen and other connective tissues, leading to a reduction in skin thickness and strength. As a result, individuals taking corticosteroids may notice that their skin becomes more fragile, which is manifested as easy bruising and increased susceptibility to skin tears.

Thin skin is a direct consequence of this effect and is particularly relevant in long-term corticosteroid use. The skin's ability to withstand minor trauma diminishes, making it more prone to injury and resulting in visible bruising even with minimal impact. Therefore, the association of corticosteroids with fragile skin and easy bruising is accurately captured by the identification of thin skin as the correct response.
