Yes, closely. Both full ingredient lists combine silicones with squalane and tetrahexyldecyl ascorbate, a vitamin C derivative. RejuvaSil also lists emu oil; Scarless also lists silica and isopropyl myristate; and the silicones have different names. Similar ingredient lists do not mean identical results.
Comparison
Scarless vs RejuvaSil: silicone scar gel comparison
Scarless is a topical silicone scar gel from Goodness Care. RejuvaSil is described on the manufacturer's US website as a medical-grade silicone scar gel. Their ingredient lists overlap closely, and neither is for open wounds. This page sets out what they share and what differs; it does not compare results.

The 30-second comparison
- Scarless and RejuvaSil are both silicone scar gels for healed, closed skin.
- Their formulas overlap closely: both list silicones, squalane and tetrahexyldecyl ascorbate, the same vitamin C derivative.
- What differs is smaller: RejuvaSil's list includes emu oil; Scarless's includes silica and isopropyl myristate; and the silicones they list have different names.
- Both are applied two to three times a day. In the US, RejuvaSil comes in 15 mL and 30 mL sizes; Scarless comes in a 15 g tube.
- Similar ingredient lists do not mean identical results. No published study of either finished gel, or comparing the two directly, has been identified, so neither can be said to work better.

What they have in common
Based on each product's own published information:
- A silicone scar gel. Both are silicone gels for scars.
- Squalane. Both list squalane.
- The same vitamin C derivative. Both list tetrahexyldecyl ascorbate.
- Two to three times a day. Both are applied two to three times a day.
- Closed skin only. Neither is for open wounds.
The differences that matter most
A closely overlapping formula. The most notable point is how much the two share. Both full ingredient lists combine silicones with squalane and tetrahexyldecyl ascorbate, the same vitamin C derivative under the same ingredient name. Neither formula is more advanced for it, and the overlap says nothing about results.
The remaining ingredient differences. RejuvaSil's list includes emu oil, which is not on Scarless's list. Scarless's list includes silica and isopropyl myristate, which are not on RejuvaSil's. The silicones are named differently: cyclomethicone and dimethicone crosspolymer in RejuvaSil; dimethicone, dimethiconol, cyclopentasiloxane and cetyl dimethicone in Scarless.
Sizes and range. The daily routine is the same, two to three times a day, so the practical differences are in the packs: in the US, RejuvaSil comes in 15 mL and 30 mL sizes, and its range adds Scar Fx silicone sheeting and kits that pair the sheeting with the gel. Scarless is one gel, in a 15 g tube.
Formula compared
What they share. Both lists include silicones, squalane and tetrahexyldecyl ascorbate. In Scarless, the squalane is olive-derived; RejuvaSil describes its squalane as plant-derived, commonly from olives, and its tetrahexyldecyl ascorbate as a stable version of vitamin C. It is the same ingredient, under the same name, in both lists.
What differs. RejuvaSil lists emu oil; Scarless does not. Scarless lists silica and isopropyl myristate; RejuvaSil does not. And the silicones are different compounds by name: cyclomethicone and dimethicone crosspolymer in RejuvaSil, against dimethicone, dimethiconol, cyclopentasiloxane and cetyl dimethicone in Scarless.
Scarless. Its full ingredient list has seven INCI entries: silicones (dimethicone, dimethiconol, cyclopentasiloxane and cetyl dimethicone) with silica, plus squalane, isopropyl myristate and tetrahexyldecyl ascorbate, a vitamin C derivative.
RejuvaSil. Its US product page gives a full list of five ingredients: cyclomethicone, dimethicone crosspolymer, tetrahexyldecyl ascorbate, emu oil and squalane.
Similar lists, not proven equal results. An ingredient list shows what is in a gel, not the proportions or how the finished formula performs. Similar lists do not mean identical results, and an extra ingredient on either side does not make one better. No study has compared the two products.
Application and daily routine
Each manufacturer's own instructions, side by side:
- How to apply. Scarless: squeeze out a small amount, spread a thin layer over the scar and rub in gently until it dries. RejuvaSil, according to its US product page: apply it and let it dry before clothing goes over the area.
- How often. The same for both: two to three times a day.
- Make-up. Scarless can be covered with cosmetics or sunscreen once it has dried. RejuvaSil's US product page describes it as non-greasy, leaving no residue, and ideal for use under make-up. See how to apply Scarless.
- Day to day. The routines are alike: two or three applications a day, each left to dry before clothing covers the area. Scarless dries in a few minutes.
Formats, pack sizes and coverage
Gel sizes. In the US, RejuvaSil is sold in 15 mL and 30 mL sizes. Scarless comes in a 15 g tube. RejuvaSil's sizes are volumes and Scarless's is a weight, so the figures are not directly comparable.
The wider range. RejuvaSil's range also includes Scar Fx silicone sheeting, intended for night-time with the gel used by day, and Scar Heal Kits that pair the gel with the sheeting. These are separate products; everything in the table refers to the gel. Scarless is a gel only.
Scar types, stages and intended use
- Healed, closed skin only. Scarless is applied once the wound has fully closed and sutures are removed. RejuvaSil's US product page says to begin only once stitches have been removed or have fully dissolved and the wound has completely closed, with intact skin and no open areas.
- Scar types each one names. Scarless: surgical, C-section, burn, hypertrophic and keloid-type scars. RejuvaSil: facial, surgical, burn and traumatic scars, keloids and hypertrophic scars. These are the manufacturers' own descriptions, not an independent comparison of results.
Practical-use considerations
- Drying and clothing. Scarless dries to an invisible film in a few minutes. RejuvaSil is described as a clear, matte gel, and its product page advises letting it dry before clothing goes over the area.
- Sun protection. Scarless has no built-in SPF, and sunscreen can be applied over it once it has dried.
What the evidence can and cannot tell us
Silicone as a class. Silicone gels and sheets are widely recommended in scar-management guidance, particularly for hypertrophic scars and keloids. However, systematic reviews have found that the certainty of evidence for some outcomes is low or very low.
RejuvaSil itself. No published study of RejuvaSil as a finished product has been identified.
The shared ingredients. Research on squalane and on vitamin C derivatives looks at the ingredients themselves, not at either finished gel. Because both gels list them, that research does not tell the two apart.
Scarless itself. The published research that Goodness Care cites is on silicone, on the individual ingredients and on related formulations, not on Scarless as a finished product.
A direct comparison. No published study comparing Scarless and RejuvaSil directly has been identified.
Scarless may help improve the appearance of scars. More on the research, and its limits, is on the published research page.
Which may suit different priorities?
Each has documented features that may matter to different people:
- RejuvaSil may suit someone who wants a larger size (in the US it is also sold in 30 mL), a range that pairs the gel with silicone sheeting for night-time, or a formula that includes emu oil. Its product page describes it as ideal for use under make-up.
- Scarless may suit someone who wants silicones, squalane and a vitamin C derivative in a gel whose complete ingredient list does not include emu oil, and that can be covered with sunscreen or make-up once it has dried after a few minutes.
- If you are not sure which suits your scar, a pharmacist or doctor can advise.
Frequently asked questions
Both list squalane. In Scarless it is olive-derived; RejuvaSil describes its squalane as plant-derived, commonly from olives.
Yes. Both list tetrahexyldecyl ascorbate, under the same ingredient name; RejuvaSil describes it as a stable version of vitamin C. Containing the same ingredient does not show that the two gels perform the same.
RejuvaSil's list includes emu oil, which is not on Scarless's list. Scarless's list includes silica and isopropyl myristate, which are not on RejuvaSil's. The silicones listed also differ by name: cyclomethicone and dimethicone crosspolymer in RejuvaSil; dimethicone, dimethiconol, cyclopentasiloxane and cetyl dimethicone in Scarless.
Both are applied two to three times a day.
In the US, RejuvaSil is sold in 15 mL and 30 mL sizes, and its range also includes Scar Fx silicone sheeting and kits. Scarless comes in a 15 g tube.
Scarless: yes, once dry, cosmetics or sunscreen can go over it. RejuvaSil's US product page describes it as ideal for use under make-up.
No. Both are for closed skin. Scarless must not be applied to open wounds or unhealed incisions, or before sutures are removed. RejuvaSil's US product page says to start it only once the wound has completely closed and the skin is intact.
No. No published study comparing Scarless and RejuvaSil directly has been identified, and no study of either finished gel has been identified, so neither can be said to work better. Silicone gels as a group are widely recommended in scar-management guidance, and the research on squalane and vitamin C derivatives looks at the ingredients, which both gels list.
