Silicone Scar Gel After Mohs Surgery: A Guide for Canadian Dermatology Clinics
Mohs surgery leaves a defect that is closed in the same visit, often on the face, and often under some tension. The patient leaves with a dressing and a set of instructions, and the conversation about the final scar tends to arrive later. For a dermatology clinic, the useful question is when a silicone scar gel can be introduced without disturbing a healing wound.
When Is a Mohs Site Ready for Silicone Gel?
The answer is not a fixed number of days. A site is ready when it is fully closed, dry, and free of scabbing or drainage, and when the treating clinician has cleared it. For small closures that can be two to three weeks; for a flap or graft it is usually longer. Silicone gel applied to an open or oozing wound does nothing useful and can trap debris, so the review visit matters more than the calendar.
| Repair type | What the clinic checks first | Typical gel start |
|---|---|---|
| Simple linear closure | Skin closed, sutures out, no drainage | Around 2–3 weeks |
| Flap repair | Flap settled, edges sealed | Often 3–6 weeks |
| Full-thickness graft | Graft taken, no open areas | Usually 6 weeks or more |
| Second-intention healing | Complete re-epithelialisation | Only after the surface has closed |
Why Mohs Scars Need Their Own Routine
Mohs defects are frequently on the nose, ear, lip or cheek, where skin is thin and movement is constant. That combination makes a raised or stretched scar more likely, and it makes a thick layer of gel harder to keep in place. A thin film that sets without shine is easier for a patient to wear under sunscreen and makeup, which is what keeps the routine going at all.
The evidence base for silicone in scar management is summarised in a Cochrane review of silicone gel sheeting for hypertrophic scars and in a review of therapeutic methods for keloid and hypertrophic scars. What those sources support is consistent, daily use over months, not a single application after the procedure.
How Should the Routine Be Handed Over?
- Confirm closure in person before the patient starts.
- Show the film thickness once in clinic rather than describing it.
- Set a realistic duration: three to six months, reviewed at intervals.
- Pair the gel with sun protection, because pigment change on a facial scar is what patients notice first.
- Give a written review date, and keep a photo at each visit.
What Does the Clinic Need on the Shelf?
A scar review is a small procedure of its own. A clean gloved hand and a fresh wipe come first, so nitrile examination gloves and disposable dry wipes sit alongside the gel in the same drawer. Where a clinic also handles small dressing changes, sterile gauze sponges and cloth medical tape round out the kit. The gel used in this routine is stocked as CliniEco Medical Silicone Scar Gel, a 15 g tube of medical-grade silicone.
Scar gels sold in Canada with therapeutic claims are regulated as natural health products under the Natural Health Products Regulations (SOR/2003-196), so confirm the label carries a Natural Product Number before the product is written into a protocol.
Clinics that stock for a full patient list can review wholesale clinic pricing and the wholesale terms page before ordering.

Frequently Asked Questions
When can silicone scar gel start after Mohs surgery?
Only once the site is fully closed, dry and free of scabbing, which for many Mohs defects is several weeks after the procedure. The exact date depends on how the defect was repaired and should come from the treating dermatologist rather than a generic timeline.
Does silicone gel replace the dressing after Mohs surgery?
No. The surgical dressing and any wound care instructions come first. Silicone gel is a scar management step that begins after the wound has healed, not a dressing and not a substitute for one.
Why is the Mohs scar site different from other scars?
Mohs sites often sit on the face, heal under tension, and follow a repair that may involve a flap or graft. Those factors change both the healing time and how visible the final scar is, so the gel routine is usually reviewed in person before it is handed over.
Should a clinic photograph the site at each visit?
Yes. A dated photo at each review is the simplest way to show progress, and it also gives the patient a reason to keep the routine going when the scar looks unchanged from week to week.
