A day-by-day guide to wound care, activity limits, and healing
Once your basal cell carcinoma has been removed — whether by excision, Mohs surgery, or another method — your attention shifts from "getting the cancer out" to "getting the wound to heal well." That's a good problem to have, but it comes with its own set of questions: How do I take care of this? When can I go back to normal activities? What's a normal part of healing, and what's a sign something's wrong?
Every surgeon's specific instructions may vary slightly depending on the closure technique used, so the written aftercare sheet you're given at discharge always takes priority over general guidance. This article walks through what recovery typically looks like, so you know what to expect and when to call your doctor.
The initial pressure bandage placed in the operating room does important work — it controls bleeding and protects the fresh wound. Most surgeons ask you to leave it undisturbed for the first day or two.
Once you're cleared to start cleaning the wound yourself, a simple routine — repeated once or twice a day until the wound is closed — supports healing and lowers infection risk. A 2024 dermatologic surgery review found that keeping a wound clean, moist, and covered promotes faster healing with less scarring than letting it dry out and scab over.
Wash your hands first. Clean the wound with plain soap and water or the solution your surgeon recommends, using a soft cloth, gauze, or cotton swab to remove any crust or drainage. Avoid scrubbing.
Pat the area dry, then apply a thin layer of plain petroleum jelly (such as Vaseline) unless your surgeon has prescribed something specific. Routine antibiotic ointment isn't usually necessary and can occasionally cause an allergic skin reaction — plain petrolatum works just as well for most wounds.
Cover with a non-stick gauze pad or bandage as directed. Keeping the wound covered protects it from friction and contamination while it's most vulnerable.
Continue this cycle daily (or as instructed) until the wound has fully closed over — typically one to three weeks depending on the size, location, and how it was repaired.
Some redness, mild swelling, and tenderness are expected right after surgery. Contact your surgeon's office if you notice any of the following:
Closing over is only the first stage. Underneath the surface, a scar continues to remodel for months — often becoming firmer, pinker, or slightly raised around weeks 2-6 before gradually softening and fading. Full scar maturation can take up to a year, particularly on the face, where surgeons take extra care with reconstruction to preserve function and appearance (as outlined in joint clinical guidelines from major dermatologic and plastic surgery societies).
Once your wound has fully healed, protecting the area from the sun — with clothing or a broad-spectrum SPF 30+ sunscreen — helps the scar fade rather than darken, and is part of your ongoing defense against new skin cancers nearby.
Recovery after BCC surgery follows a fairly predictable path: a cautious first day or two, a couple of weeks of simple daily wound care while activity stays limited, and then months of quieter scar maturation in the background. Most people are back to their normal routine well before the wound is finished healing underneath the surface.
If anything about your healing feels off compared to what you were told to expect, it's always reasonable to call your surgeon's office rather than wait it out — catching a problem like infection early keeps recovery on track.
