Which topical ointment can influence healing when used alongside steroids?

1. Vitamin C

2. Corticosteroids

3. Vitamin A

4. Antibiotics

The correct answer is: Vitamin A

The use of Vitamin A in wound healing, especially when used in conjunction with steroids, is significant due to its essential role in cellular growth and tissue repair. Vitamin A is vital for skin health and plays a crucial part in the regulation of epithelial cell growth and differentiation. When applied topically, it can help stimulate the production of collagen and promote epithelialization, which are critical processes for effective wound healing. In the context of steroid use, which can have anti-inflammatory effects but may also inhibit certain aspects of the healing process, Vitamin A can help counterbalance some of these negative impacts by promoting healing and improving the quality of the healed skin. Its application can be particularly beneficial in cases where steroids might delay wound closure or alter collagen synthesis. While other options may have their own roles in wound care, like antibiotics preventing infection or corticosteroids managing inflammation, they don't specifically enhance the healing process in the same way that Vitamin A does. Therefore, the substantial evidence supporting the role of Vitamin A in facilitating healing alongside steroid use makes it the most appropriate choice in this context.
