Why Small Scars Get Undertreated, and What That Costs
In my practice, I see a pattern that genuinely frustrates me. A patient goes through a carefully executed procedure, the incision heals cleanly, and then nothing. No scar protocol. The reasoning is usually something like, It's just a small scar. Three months later, they come back asking why it's thickened, why it's still pink, why it feels raised along the edges.
Small scars are not low-stakes scars. A one-inch incision near the jaw, a short excision line on the chest, a minor surgical cut on the shoulder: these are exactly the sites where inadequate early management can produce a result that's disproportionate to the original intervention. The biology does not scale with wound size. A small scar in a high-tension anatomical area can hypertrophy just as readily as a larger one, sometimes more so.
This is why I take scar management seriously for every incision, regardless of length.

How Silicone Reduces TEWL and Regulates Collagen During Scar Remodeling
Most explanations of silicone therapy stop at the protective barrier and hydration. That is a significant oversimplification of what is actually happening at the tissue level.
When silicone is applied to a maturing scar, it creates a semi-occlusive microenvironment that reduces transepidermal water loss, TEWL. Unlike fully occlusive dressings, silicone sheeting allows gas exchange while blocking excess transepidermal water vapor loss, which is what makes it suitable for long-term daily wear over maturing skin. Normal intact skin loses a controlled amount of water vapor through its surface. Scar tissue, which lacks intact epithelial architecture in the early months, loses water at a higher rate. That excess TEWL creates a state of low-grade chronic desiccation at the scar surface.
Here is where it gets clinically meaningful. When the scar microenvironment is persistently dry, fibroblasts respond by increasing their activity and producing more type I collagen, the denser, stiffer collagen that creates that firm, ropey scar texture. By restoring a properly hydrated environment through occlusion, silicone appears to shift fibroblast behavior toward a less hyperactive state, promoting a healthier ratio of type I to type III collagen during the remodeling phase. Type III collagen is softer, more organized, closer to what normal dermis looks like.
This is not theoretical. The International Advisory Panel on Scar Management has recognized silicone gel sheeting as a first-line treatment for hypertrophic scars, and Mustoe et al. (2002) in their international clinical recommendations established silicone as the most evidence-supported non-invasive intervention available for scar management. Gold et al. subsequently confirmed these findings in controlled trials, showing measurable improvements in scar height, texture, and vascularity with consistent silicone use over 12 to 24 weeks.
When to Start: Reading the Wound Before Applying the Strip
This question comes up constantly, and I want to give a specific answer rather than a vague one.
I tell my patients to begin silicone therapy within two weeks of suture removal, provided the wound is fully epithelialized. Fully epithelialized means the surface is closed, no scabbing, no open areas, no wound edges that are still separating. The skin should feel continuous to the touch. Visually, there should be no crusting and no raw-looking tissue.
If silicone is applied before the wound reaches this point, you risk two things. The occlusive environment can trap bacteria against compromised skin, creating conditions for infection. You can also cause maceration, where the surrounding tissue softens excessively and the wound margins break down. Neither outcome is worth rushing.
A good practical check: if you press gently on the incision site and release, does the surface hold its shape? If the answer is yes and the skin looks intact, it is ready. If there is any doubt, wait another week and reassess.
Signs the wound is ready for silicone therapy: The skin surface is fully continuous with no open areas or separating wound edges. There is no visible crusting or raw tissue along the incision line. The surrounding skin shows no signs of active inflammation or excessive warmth. When gentle pressure is applied and released, the surface holds its shape without indenting or weeping.
Why Strip Format Matters for Small Scars in High-Mobility Areas
Large silicone sheets work well for broad scars across the abdomen, back, or thigh. They are not the right tool for a 2 cm scar along the jawline, behind the ear, or over the deltoid.
The clinical issue with oversized sheets in these areas is adhesion and mechanical stability. The skin near joints and facial structures moves constantly. A large sheet applied across a small mobile area lifts at the edges, folds, and loses contact with the scar itself. When contact is lost, the occlusive mechanism breaks down. You lose the TEWL benefit entirely for those periods.
A small, purpose-fit strip maintains full contact with the scar because it flexes with the tissue rather than fighting against it. The Silagen Clear Strips 1" x 3" format is specifically designed for this use case: short incisions where precision placement and consistent adhesion matter more than broad coverage. For a scar near the ear, over a knuckle, or along a nasolabial fold, the smaller footprint means the strip actually stays where it needs to be throughout the day.
Hypertrophic Scars vs. Keloids: Who Needs Early Silicone Therapy Most
These two terms get conflated constantly, even by patients who have done their research.
A hypertrophic scar stays within the boundaries of the original wound. It raises, thickens, and may stay pink for months, but it does not expand laterally beyond the incision margins. A keloid does expand beyond those margins. It invades surrounding normal tissue and, critically, it does not spontaneously regress the way hypertrophic scars often do over time.
Silicone therapy is well-supported for hypertrophic scar prevention and management. The evidence for keloids is less conclusive, though silicone is still used as part of a broader treatment strategy in keloid-prone patients.
In my practice, I start preventive silicone therapy early on any patient with the following risk profile: Fitzpatrick skin types III through VI, where in these skin types, inadequate scar management does not just risk hypertrophy, it also creates conditions for post-inflammatory hyperpigmentation, where the scar site darkens significantly and becomes a separate cosmetic concern on top of the texture problem. I also prioritize patients with a personal history of hypertrophic scarring or keloids, incisions over the chest or shoulder (both notorious sites for poor scarring), or scars resulting from procedures involving significant tension closure. These patients do not have the luxury of a casual approach to scar management.
The 12 to 18 Month Window: Where Silicone Fits in the Healing Phases
Wound healing follows three sequential phases. The inflammatory phase, which runs roughly the first week, involves the vascular and cellular response to injury. The proliferative phase, which extends from week two through month three or four, is when new collagen is rapidly deposited and the wound contracts. The remodeling phase begins around month three and continues for 12 to 18 months, during which the collagen network is reorganized and the scar gradually matures.
Silicone therapy is most effective during the remodeling phase, but that is not a reason to wait until month three to start it. This is why I recommend prophylactic silicone therapy beginning in the late proliferative phase rather than waiting until the scar becomes visibly problematic. Continuing through the full maturation window is where the cumulative benefit comes from. Stopping at six weeks because the scar looks better is a common mistake. The scar is not done remodeling just because it looks calmer.
I tell patients to think of the first 12 months as the active treatment period, with the understanding that some scars, particularly those on the chest or in patients with a history of poor healing, warrant continued management beyond that.
What I Actually Recommend to My Patients
For any short incision, I recommend silicone strip therapy starting within two weeks of suture removal and continuing daily for a minimum of three to six months, with reassessment at that point. I prefer the strip format for facial scars, joint-adjacent scars, and any incision under roughly two inches, where a full sheet would be oversized and difficult to stabilize. For patients managing larger or multiple scar sites, additional silicone formats are available in the scar care products collection.
In patients who complete a consistent three to six-month silicone protocol starting within the first two weeks post-suture removal, I routinely see measurable differences at follow-up. Scar elevation reduces. The erythema that typically persists for months in undertreated scars fades faster. The texture, which in poorly managed scars feels firm and ropey even at six months, has usually begun to soften toward something closer to the surrounding dermis. These are not dramatic transformations. They are the compounded result of the scar remodeling in a properly maintained environment rather than despite a neglected one.

Frequently Asked Questions About Silicone Strip Therapy
-
When can I start using silicone strips after surgery?
I typically recommend starting within two weeks of suture removal, but the wound must be fully epithelialized before silicone goes on. What that means in practice: the skin surface should be completely continuous, no open areas, no raw tissue, no crusting along the incision line. If you press gently and the surface holds its shape without weeping, it is ready. When in doubt, give it another week. -
How many hours a day should I wear silicone strips?
The target is 12 hours of daily wear at minimum. The mechanism depends entirely on contact time: the strip needs to be on the scar, creating that semi-occlusive environment, for the TEWL reduction to have any clinical effect. If your skin is initially sensitive to the adhesive, start with 6 to 8 hours and build up over the first week rather than abandoning the protocol entirely. -
Can silicone strips be used on older scars?
Yes, but with realistic expectations about what is achievable. The scar remodeling window runs roughly 12 to 18 months from the time of injury. Scars treated within that window respond most readily because the collagen network is still being reorganized. For scars older than 18 months, silicone can still help with surface texture and redness, but the structural changes that happen during active remodeling are no longer available. -
What is the difference between a hypertrophic scar and a keloid?
A hypertrophic scar thickens and raises but stays within the original wound boundaries, and it often softens on its own over 12 to 24 months. A keloid extends beyond those boundaries into surrounding normal tissue and does not regress spontaneously. Silicone therapy has strong evidence for hypertrophic scar prevention and management. For keloids, silicone is part of a multimodal approach, but patients with a known keloid history should be evaluated for additional treatments such as intralesional corticosteroids or pressure therapy alongside silicone use. -
Do silicone strips work on chest and shoulder scars?
The chest and shoulder are two of the highest-risk anatomical sites for hypertrophic scarring, which is exactly why I prioritize early silicone therapy in those locations. The skin in these areas is under consistent mechanical tension, and that tension drives the fibroblast overactivation that leads to thickened scars. The strip format specifically helps here because these areas involve constant movement: a large sheet loses adhesion quickly across the shoulder or sternum, while a properly sized strip maintains the contact needed for consistent TEWL reduction throughout daily activity.
