**Core Concept**
Topical steroids are commonly used to reduce inflammation and prevent scarring in various skin conditions. However, their use post-surgery can be counterproductive, leading to wound complications and delayed healing.

**Why the Correct Answer is Right**
The use of topical steroids post-surgery can suppress the immune response, leading to an increased risk of wound infections, delayed healing, and potentially, the formation of hypertrophic scars. This is because steroids inhibit the production of inflammatory cytokines, which are essential for the initiation of the healing process. Furthermore, topical steroids can also cause atrophy of the skin, leading to thinning of the skin and increased susceptibility to trauma.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it is a common indication for topical steroids, not a contraindication.
**Option B:** This option is incorrect because it is not a recognized contraindication for topical steroids post-surgery.
**Option C:** This option is incorrect because it is a potential benefit of topical steroids, not a contraindication.

**Clinical Pearl / High-Yield Fact**
It is essential for surgeons to weigh the benefits of topical steroids against the potential risks of delayed wound healing and infection. A general rule of thumb is to avoid topical steroids for at least 2-3 weeks post-surgery to allow for adequate healing.
