The goal of this study clinical trial is to learn if topical timolol can accelerate healing and improve the cosmetic appearance of surgical wounds on the scalp following Mohs surgery. It will include Geisinger patients 18 year or older who undergo Mohs surgery of the scalp with planned wound healing by secondary intent. The main questions in aim to answer are:
1. Compare wound healing speed between patients treated with topical timolol and those receiving standard wound care only.
2. Compare cosmetic outcomes using topical timolol and standard wound care.
3. Evaluate the impact of topical timolol on the number of unplanned follow-up visits and calls related to delayed wound healing.
Participants will be asked use either topical timolol or use standard wound care to treat their Mohs surgery scalp wound. They will follow-up around 4, 8 and 12 weeks.
