Quick Answer
What it is: Silagen 100% Pure Silicone Gel is a medical-grade, single-ingredient silicone therapy that creates a semi-occlusive microenvironment over a healing scar.
When to start: Once the wound is fully closed with no open areas, crusting, or active drainage, typically 2 to 4 weeks post-procedure.
How long: Apply twice daily for a minimum of 8 to 12 weeks. Hypertrophic scars and keloid-prone patients should continue for up to 6 months.
Who it is for: Patients recovering from surgical procedures on the face, neck, chest, and other sites where a strip format is impractical, and patients managing irregular, curved, or small-surface scars that require conforming daily coverage.
Why I Choose Gel for Certain Scars
Silicone strips are my first recommendation for straight post-surgical incisions on the trunk and extremities. But a significant portion of my surgical patients present with scars that strips simply cannot address: the perioral area after a lip lift, the neck after a platysmaplasty, the periorbital region after blepharoplasty, a small mole removal on the cheek, or a curved contour following a rhinoplasty base modification. For these patients, I reach for Silagen 100% Pure Silicone Gel.
Gel applies to any surface geometry. It dries to a thin, invisible film that moves with the skin. For patients returning to work within a week of surgery, that means effective scar therapy running continuously under sunscreen and makeup without any visible appliance. That combination of clinical performance and discretion is what keeps it in my post-operative protocol.
How Silicone Gel Works at the Tissue Level
The mechanism is not hydration in the consumer-product sense. When Silagen Silicone Gel is applied to a closed scar, it forms a semi-occlusive barrier that significantly reduces transepidermal water loss TEWL from the scar surface. Scars have disrupted stratum corneum architecture. They lose water at rates far higher than intact skin, and that sustained dryness is a mechanical trigger for continued fibroblast activity.
When fibroblasts in the dermis detect ongoing moisture loss, they interpret the signal as continued injury. The response is upregulated collagen synthesis. The collagen produced in this environment is predominantly type I collagen dense, disorganized, and responsible for the raised, firm texture of hypertrophic scars. Silicone occlusion interrupts this cycle. By restoring a normalized TEWL environment, it downregulates fibroblast activation, shifts the collagen synthesis balance toward type III collagen the softer, more organized subtype that characterizes healthy dermis and allows the scar remodeling process to proceed without the feedback loop driving overproduction.
The result, with consistent use, is measurable reduction in scar height, softening of texture, and improvement in color. The mechanism is physiological and the evidence is documented in peer-reviewed literature (Mustoe et al., 2002; Gold et al., 2001).
When to Choose Gel Over Strips
I use gel over strips in four specific situations.
Irregular scar geometry. A strip applied to a curved scar on the cheek or jaw will lift at the edges within hours. Gel conforms completely to three-dimensional topography regardless of contour.
Facial and periorbital scars. Strips are conspicuous on the face. Gel dries invisible and does not interfere with expression, glasses frames, or cosmetic application.
High-friction zones with clothing. The bra line and inner thigh are areas where strips delaminate from movement. Gel applied beneath fitted garments provides continuous silicone contact without adhesive-related frustration.
Small or irregularly shaped scars. Mole excision sites, small punch biopsies, and port placement scars often measure less than one centimeter in any dimension. A gel application is more accurate and less wasteful than trimming a strip.
The no-combination rule applies here. Gel and strips are not used simultaneously on the same scar. Both deliver silicone occlusion by the same mechanism. Layering them does not improve outcomes and may reduce adhesion of strip therapy if gel residue is present. Choose one format and apply it consistently.

Dr. Nazarian's Protocol for Silagen Silicone Gel
Phase 1 Wound clearance (Weeks 0 to 3): No silicone therapy of any kind is applied while the wound is healing. Open areas, active drainage, or any crusting are contraindications to starting. Applying silicone too early risks trapping bacteria and disrupting epithelialization.
For broader guidance on what to use, pause, and restart around treatment, read our guide to skin-care products before and after procedures, and always follow your provider’s instructions.
Phase 2 Initiation (Week 3 or 4, wound-dependent): Once the surface is fully closed and dry, apply a thin layer of Silagen Silicone Gel twice daily. Wash the area gently, pat completely dry, apply a layer thin enough to dry within 3 to 4 minutes, then dress or apply makeup as needed. Morning and evening applications are sufficient. Thicker applications do not improve the outcome and increase product consumption without clinical benefit.
Phase 3 Active therapy (Weeks 4 to 12): Twice daily application is maintained without interruption. At the 6-week mark, patients who are adherent typically show visible reduction in scar elevation and early color normalization. I document this at follow-up to reinforce compliance. Patients who skip applications frequently notice the difference lapsed coverage allows TEWL to rise again within 24 to 48 hours, which reactivates fibroblast response, and patients perceive this as the softening progress reversing.
Phase 4 Extended therapy for high-risk patients (Weeks 12 to 24): Patients with Fitzpatrick skin types IV through VI carry elevated risk for hypertrophic scarring and post-inflammatory hyperpigmentation. I extend gel therapy to 6 months for these patients regardless of apparent early improvement, and I discuss the PIH risk specifically silicone does not prevent PIH, but maintaining a low-inflammation scar environment reduces the triggering stimulus.

What to Expect Week by Week
Weeks 3 to 6: The scar softens to palpation. Patients with early erythema describe reduced redness at this stage. Surface texture improvement is often the first visible change.
Weeks 6 to 8: Scar height begins to reduce in patients who were adherent from initiation. Firmness decreases. The scar moves more naturally with surrounding tissue.
Weeks 8 to 12: Color normalization progresses. In patients without PIH risk, most of the aesthetic improvement achievable through silicone therapy has occurred by this point.
Beyond 12 weeks: For hypertrophic-prone and keloid-risk patients, continued therapy through 6 months serves as suppression, not active treatment. I frame it to patients as maintenance: the work is done, but stopping early in this population carries a real recurrence risk.
Hypertrophic Risk and Fitzpatrick Profiling
Not all patients scar the same way. Before initiating any silicone protocol, I assess each patient's scarring history and skin phototype.
Patients with Fitzpatrick types IV through VI produce more melanin in response to inflammation and are more likely to develop hypertrophic scars and keloid extension beyond the wound margin. For these patients, silicone therapy is not optional it is the standard of care I apply to every surgical scar, every time, regardless of how clean the wound closure looks at first assessment.
Patients with a personal or family history of keloid formation require a candid conversation before surgery. Silicone gel is part of their post-operative protocol from week three. If early hypertrophic changes appear at the 6-week check, gel therapy continues and I consider adjunctive options. Silicone is the first-line intervention; the goal is to establish the normalized moisture environment before fibroblast overactivation takes hold, not after.
Frequently Asked Questions
How do I know when my scar is ready to start silicone gel?
The wound must be completely closed no scabbing, no drainage, no open areas of any size. Run a clean fingertip across the scar. If you feel any resistance or tackiness suggesting incomplete healing, wait another three to five days and reassess. Starting silicone therapy before full wound closure risks infection and may actually disrupt the epithelial layer you need for therapy to work.
How thin is "thin enough" when applying?
A layer that dries within 3 to 4 minutes at room temperature is the right amount. If it is still tacky after 5 minutes, you applied too much. Blot the excess with a clean tissue and apply less next time. Thick applications do not speed results.
Can I apply makeup or sunscreen over silicone gel?
Yes, once it is fully dry. I ask patients to wait at least 3 to 4 minutes before layering anything over it. Sunscreen is important UV exposure to a healing scar worsens post-inflammatory hyperpigmentation, particularly in darker skin types. Silicone gel plus daily broad-spectrum SPF 30 or higher is the combination I recommend.
What happens if I miss applications?
Missing one application will not eliminate your progress, but consistency matters more with this treatment than almost any other part of post-operative care. Patients who apply once daily rather than twice, or who stop at 8 weeks instead of 12, reliably show worse outcomes at final follow-up. Think of it the same way you think about a course of antibiotics finishing matters.
Can I use silicone gel on an old scar?
Silicone is most effective on scars under 12 months old when active remodeling is still occurring. On mature scars, the benefit is more limited, but patients with old hypertrophic scars do report softening and some flattening with extended use. It is a reasonable first step before considering laser or procedural intervention.
Is silicone gel safe to use near the eyes?
I use it on periorbital scars routinely following blepharoplasty. Apply carefully, allow it to dry fully before opening the eyes, and avoid direct contact with the eye surface. If any irritation develops, discontinue and contact the office.
