How Much Silicone Scar Gel Per Application? Dosing and Coverage in Canada
Most clinics treat silicone scar gel as a simple purchase and a surprisingly complicated habit. Once a tube reaches the treatment room, the practical question is how much to apply. A film that is too thin never forms; a film that is too thick is wiped off within the hour, and the tube empties faster than the reorder schedule assumed.
How Much Silicone Scar Gel Should Be Applied Each Time?
The working standard in most Canadian clinics is a thin, even film over the scar and a few millimetres of the surrounding skin, with no visible excess. As a rule of thumb, that is about a grain of rice for every 2 to 3 cm of scar length. The gel is spread rather than rubbed in, then left to air dry.
Scar width barely changes the volume used. What changes consumption is how often it is applied, how large the treated area is, and how many patients a clinic sees in a day.
| Scar or site | Approx. gel per application | Notes |
|---|---|---|
| Small scar, up to 3 cm | Grain of rice | Typical for facial and hand scars |
| Mid-length scar, 3–10 cm | Thin film, about 0.1 mL | Most post-surgical abdominal and limb scars |
| Long scar, 10–20 cm | Thin film, about 0.2 mL | C-section and graft sites; allow longer drying time |
| Over 20 cm or two sites | Build up in two thin passes | Let the first layer dry before adding the second |
How Far Does a 15 g Tube Actually Go?
A 15 g tube holds roughly 13 to 15 mL. At about 0.1 mL per application and two applications a day, a patient treating a mid-length post-surgical scar uses on the order of 6 mL a month. That puts one tube at roughly six weeks of twice-daily use, or closer to two to three months at once daily. For a clinic running a scar programme across twenty patients, that monthly figure is what belongs on the standing order.
What Changes the Amount a Clinic Uses?
- Scar age: a fresh, red scar takes a thinner film than a mature, raised scar that needs a full covering layer.
- Site: the face tolerates less product, while the chest and back need more coverage because the area is larger.
- Adherence: a heavy layer once a day is not the same exposure as a thin layer twice.
What Should a Clinic Record for Each Patient?
A dosing standard only holds if it is written down. A practical record keeps the product name and lot number, the date the scar was ready for gel, the application frequency, the quantity dispensed, the next review date, and a photo taken at each review.
Scar gels sold in Canada with therapeutic claims are regulated as natural health products under the Natural Health Products Regulations (SOR/2003-196), so a clinic should confirm the label carries a Natural Product Number before writing the product into a protocol. Cost per millilitre is a poor guide on its own; cost per patient-month is the figure that survives a budget review.
Where Dosing Meets Procurement
Once a clinic knows its millilitres per patient, the rest of the shelf is easier to plan. Every application starts with a clean gloved hand, which puts nitrile examination gloves in the same calculation, while dressing changes pull in sterile gauze sponges and cloth medical tape. The gel itself is stocked as CliniEco Medical Silicone Scar Gel in a 15 g tube.
Clinics that order for a whole patient roster can compare wholesale clinic pricing and review the wholesale terms page before the standing order is set.

Frequently Asked Questions
How much silicone scar gel should be applied each time?
A thin, even film that covers the scar and a few millimetres of the surrounding skin, with no visible excess. For most scars that is about the size of a grain of rice for every 2 to 3 cm of scar length. Spread it rather than rubbing it in, then let it air dry.
How long does a 15 g tube of silicone scar gel last?
A 15 g tube holds roughly 13 to 15 mL. At about 0.1 mL per application, twice daily, a single patient on a mid-length scar uses about 6 mL a month, so one tube lasts around six weeks of twice-daily use or two to three months once daily.
Should silicone scar gel be rubbed in?
No. Unlike a moisturiser, scar gel is spread into a thin film and left to dry in place. Massaging it in removes the film that does the work, and it also wastes product because more has to be applied to rebuild the layer.
How often should silicone scar gel be applied?
Most published protocols describe twice-daily application on clean, dry skin once the wound has closed. Where a clinic recommends once daily, it should record that choice in the patient file so the review date and quantity dispensed stay consistent.
