Silicone Scar Sheet Shapes and Sizes: Strips, Shapes or Cut to Fit

Choose a silicone scar sheet by the outline and size of the scar, not by the name on the package. A long, straight scar can be matched with a long strip. A ring, a ring with a vertical line, or a curved line along the lower breast fold can be matched with a pre-shaped sheet. A short scar can be covered with a small patch or a piece trimmed from a larger sheet.

Whichever format you choose, the makers of Scar FX, Epi-Derm and Oleeva say the sheet should cover the whole scar with a margin of skin around it. This guide compares outlines and dimensions only. Ask your surgeon or clinician when your skin is ready for silicone, which area they want covered and how long to wear the sheet.

Pre-shaped, long strip or cut to fit?

• Pre-shaped sheets come cut to an outline, such as a ring or a curved section with a vertical strip. Bio Med Sciences, the maker of Oleeva, says its Scar Shapes are cut “to ensure the correct placement and coverage,” and recommends trimming its products only if necessary.
• Long strips are straight rectangles that can be used as they are or cut to length. DirectDermaCare’s Scar FX strip listings say the sheet can be cut to fit the scar, and Rejûvaskin, the maker of Scar FX, says its sheets can be cut.
• Small patches cover a short scar. Biodermis says its Epi-Derm patches can be cut to size.

A pre-shaped sheet covers a ring or a branching outline in one piece; strips would need several pieces for the same outline. Ask your clinician whether separate pieces are acceptable for your scar.

Measure the scar, then add the margin

Measure the scar’s full length, following any curve, and its widest point. Then add the margin given by your product’s maker:

• Scar FX and Epi-Derm: Rejûvaskin and Biodermis both say the sheet should extend 1/4 inch beyond the scar all the way around.
• Oleeva: Bio Med Sciences asks for at least 1/2 inch around the entire scar.

Add the margin to both ends and both sides. With a 1/4-inch margin, a scar 6 inches long and 1/4 inch wide needs a piece at least 6-1/2 inches long and 3/4 inch wide. With a 1/2-inch margin, the same scar needs a piece at least 7 inches long and 1-1/4 inches wide. The Japan Scar Workshop’s 2018 consensus document likewise says a gel sheet should be large enough to cover the affected area.

Long strips and patches

Gel-Care strips are a different material. Silipos, the maker of Gel-Care Advanced, says the strips “do not contain silicone.” If your instructions call for silicone sheeting, ask your clinician before choosing Gel-Care.

Breast silicone scar sheets: shapes compared

Breast-area shapes differ in which parts they include: a ring around the areola, a vertical strip below it, a curved section along the lower fold, or all three. Rejûvaskin notes that the sheet you need depends on the incision rather than the procedure, so compare each outline with your scar and your surgeon’s instructions.

Two details are easy to miss. First, the Oleeva Anchor Shape Silicone Scar Sheet and the Scar FX Silicone Sheet Breast Piece have no ring. The Oleeva Breast Form Kit adds a separate areola ring to the Oleeva anchor shape, while the Scar FX Silicone Sheet Breast Anchor includes the ring in a single piece. Second, each listing in this table is one sheet or one kit, so choose quantity 2 if you need one for each side. Our Scar FX Breast Anchor vs. Areola Circle guide compares those two Scar FX shapes in more detail.

Rejûvaskin’s diagram labels the ring-with-a-vertical-strip outline “Lollipop.” The two lollipop-outline listings above differ in length, so compare each with your measured scar plus its margin.

A pre-shaped sheet for the abdomen

The Oleeva C-Section Shape Silicone Scar Sheet is a gently curved horizontal strip measuring 2 x 9 inches. With the 1/2-inch margin Bio Med Sciences asks for at each end, a 9-inch piece covers a scar up to 8 inches long. For a longer horizontal scar, compare the long strips above.

Before you open or trim a sheet

• Ask your clinician when to start. Rejûvaskin says its products should be applied only to closed skin with no drainage, and Bio Med Sciences says Oleeva is not for use over sutures, staples or open wounds.
• Follow the instructions in your package for wearing time and cleaning. They differ from brand to brand; our guide on how to use silicone scar sheets compares them.
• Check the size before you open the package. You can request a return of unopened products within 60 days of delivery; opened or used products can be returned only if they arrived damaged or defective. Read the full return policy.
