Himplasia vs Alternatives: Which Hypertrophic Scar Treatment Comes Out on Top?

Scar tissue can turn a simple cut into a lifelong reminder. When the scar raises above the skin, turns pink or red, and becomes itchy or painful, many call it a hypertrophic scar. Finding a treatment that actually flattens the scar without causing new problems is a common worry. Below we break down Himplasia and stack it up against the most popular alternatives, so you can pick the option that fits your skin, budget, and lifestyle.

What is Himplasia?

Himplasia is a topical silicone‑gel formulation designed to hydrate the scar surface and create a semi‑occlusive barrier. The gel’s high‑molecular‑weight silicone polymer reduces transepidermal water loss, which in turn normalises collagen production and encourages the scar to lay flatter. First approved in the UK in 2022, Himplasia is marketed as a prescription‑only product, usually supplied in 30‑ml squeeze tubes. Patients apply a thin layer twice daily, letting it dry for a few minutes before covering the area with a light dressing if desired.

How Do the Main Alternatives Work?

Before you decide, it helps to know the science behind the other options that show up on pharmacy shelves or dermatologist offices.

• Silicone gel sheeting is a thin, flexible sheet made from medical‑grade silicone. It works by applying constant pressure and moisture, similar to Himplasia, but in a reusable format. The sheet stays on for up to 24hours before being washed off.
• Mederma (onion extract gel) claims to soften scar tissue through botanical anti‑inflammatory compounds. It is an over‑the‑counter cream applied twice daily.
• ScarAway silicone patches combine silicone with a self‑adhesive layer, offering a middle ground between sheets and gels. They are pre‑cut to common scar shapes.
• Corticosteroid injection delivers a potent anti‑inflammatory drug directly into the scar. It is typically performed in a clinic and repeated every 4‑6 weeks.
• Laser therapy (fractional CO₂ or pulsed‑dye lasers) remodels scar tissue by vaporising excess collagen and stimulating new, healthier skin growth.
• Pressure therapy uses custom‑fitted garments that exert constant pressure (often 20‑30mmHg) on the scar, a technique most often used for burn‑related hypertrophic scars.

Choosing the Right Option for Your Scar

Every scar has its own story: location, depth, age, and the skin type of the person involved. Below are the top decision factors you should weigh.

1. Scar maturity. Fresh scars (under 3months) respond better to silicone‑based barrier methods like Himplasia or sheets. Older, established hypertrophic scars often need a more aggressive approach such as corticosteroid injections or laser resurfacing.
2. Convenience. If you travel often or dislike daily routines, a reusable silicone sheet or a pre‑cut ScarAway patch may win over a twice‑daily gel.
3. Cost sensitivity. Over‑the‑counter creams (Mederma) and patches are cheap but typically less effective. Himplasia sits in the mid‑range, offering prescription‑grade results without the clinic fees of injections or lasers.
4. Skin tolerance. People with sensitive skin may experience irritation from adhesive patches or the strong onion scent of Mederma. Himplasia’s hypo‑allergenic gel is formulated to minimise reactions.
5. Medical supervision. If you prefer a hands‑off regimen, stick with topical silicone options. If you want a clinician to monitor progress, consider injections or laser sessions.

In practice, many dermatologists start patients with a silicone‑based product (Himplasia or sheet) for the first 3months. If the scar plateaues, they add an injection or laser as a second line.

Practical Tips for Using Himplasia Safely

• Clean the scar gently with mild soap and pat dry before each application.
• Apply a pea‑size amount and spread it thinly; thick layers can trap moisture and cause maceration.
• Allow the gel to set for 2-3minutes before covering it with a breathable bandage, especially on joints.
• Store the tube at room temperature; extreme heat can break down the silicone polymers.
• Track progress with weekly photos. Most users notice a softening effect within 4-6weeks.

Cost and Accessibility in the UK

Himplasia is a prescription‑only medication, meaning you’ll need a GP or dermatologist to write it. Some private clinics stock it directly, often charging a dispensing fee on top of the £45‑£55 product price. In contrast, silicone sheets can be bought from pharmacies without a prescription, while laser and injection treatments require specialist visits that can quickly exceed £1,000 for a full course.

Insurance coverage varies. The NHS rarely funds silicone gels unless the scar is causing functional impairment, but private health plans sometimes include a limited number of laser or injection sessions. If budget is tight, a silicone sheet or an over‑the‑counter patch may be the most affordable entry point.

Bottom Line

If you’re looking for a clinically backed, prescription‑strength option that balances efficacy, convenience, and side‑effect profile, Himplasia is a solid choice. It outperforms many over‑the‑counter creams and rivals silicone sheets in flattening rates, while staying far cheaper and less invasive than laser or injection routes.

That said, no single product works for everyone. Match the treatment to your scar’s age, your willingness to attend clinic appointments, and your pocketbook. Starting with a silicone barrier (Himplasia or sheet) and escalating only if needed gives you the best chance of a smoother, less noticeable scar without unnecessary hassle.
