Scarless vs. a silicone-only gel
Most scar gels on a pharmacy shelf are silicone and nothing else. That is a sound starting point — the occlusive silicone film is the most studied non-invasive approach to scar management. This page sets that approach next to Scarless, which keeps the same silicone film and adds squalane and a stable vitamin C derivative, and says plainly where each one fits.

At a glance
Both products do the same core job: a self-drying silicone film that seals the scar, holds moisture in, and is associated in published research with softer, flatter, less red scars. The difference is what else is in the tube. Scarless adds squalane, an emollient that suits scar tissue — which has fewer oil glands than surrounding skin and often feels tight or dry — and a stable, oil-soluble vitamin C derivative. A published case series of a silicone gel containing vitamin C reported lower erythema and melanin index than no treatment, which is why tone appears in this comparison at all.
Ingredient by ingredient
| Scarless | Silicone-only gel | |
|---|---|---|
| Product type | Triple-formula silicone scar gel | Silicone-only scar gel |
| Key actives | Silicone + squalane + vitamin C derivative | Silicone only |
| Occlusive silicone barrier | Yes | Yes |
| Vitamin C derivative | Yes — stable, oil-soluble form | No |
| Squalane (emollient) | Yes — olive-derived | No |
| Self-drying, invisible film | Yes | Varies by product |
Where a silicone-only gel does well
A plain silicone gel has real strengths, and for some people it is the right choice:
- The occlusive silicone barrier is the most studied non-invasive approach to scar management — everything else in a scar gel is added on top of it.
- Fewer ingredients means fewer things to react to. If your skin is reactive, or a clinician has told you to keep a healing area simple, a single-ingredient gel is easier to reason about.
- Single-ingredient formulas are widely available and often cost less than multi-active ones.
Where Scarless goes further
Scarless keeps the silicone barrier and adds two ingredients a silicone-only gel does not carry:
- Squalane, an olive-derived emollient. Scar tissue has fewer sebaceous glands than the skin around it and often feels tight and dry; squalane is documented in published reviews as a skin-hydrating, antioxidant emollient.
- A stable vitamin C derivative. Vitamin C's role in collagen formation is established in laboratory and animal research, and a published case series of a silicone gel containing vitamin C reported lower scar elevation, erythema and melanin index than no treatment. That research is on the ingredient and on comparable formulations — not on Scarless itself.
- One step instead of two. Both ingredients sit inside the same self-drying film, so there is no separate moisturizer to layer under or over a silicone gel — which matters over the weeks to months a scar takes to settle.
How to choose
Choose a silicone-only gel if you want the silicone film and nothing else — because your skin reacts easily, because a clinician asked you to keep it simple, or because cost is the deciding factor. Choose Scarless if the scar also feels dry or tight, or if its colour bothers you as much as its texture, and you would rather handle that in the same step. Either way, the rules are the same: start only once the wound has fully closed, apply a thin layer two to three times a day, and keep going for the full two to three months. And for a scar that is painful, growing beyond the original wound, restricting movement, or simply not improving, see a doctor — no topical gel replaces that.

None of the research above was carried out on Scarless itself. The studies cover topical silicone, a silicone-and-vitamin-C formulation, and the squalane ingredient. Individual results vary, and no topical gel can remove a scar.
This is a drug-free topical gel for external use on intact, fully healed skin. Do not apply it to open wounds, unhealed incisions, or infected or irritated skin. It does not replace medical advice: ask a doctor or pharmacist about a scar that is painful, growing, restricting movement, or not improving.
