Scars are an inevitable consequence of surgery, but their final appearance is significantly influenced by post-operative management. Modern aesthetic approaches to scar treatment — including silicone therapy, microneedling, laser resurfacing, and injectable treatments — can dramatically improve scar colour, texture, height, and flexibility when applied at the right time. This guide covers the evidence-based approach to optimising surgical scar outcomes.
At Axiom Aesthetics, we help patients achieve the best possible scar outcomes following surgical procedures. Whether you have a recent surgical scar or an older scar you want to improve, this guide outlines your options.
Understanding Scar Formation
Scarring occurs when the skin heals after full-thickness injury. The process involves three overlapping phases:
- Inflammatory phase (0–7 days): Blood clotting, immune cell infiltration, early wound matrix formation
- Proliferative phase (1–6 weeks): Fibroblasts produce type III collagen, new blood vessels form, wound contracts
- Remodelling phase (6 weeks–2 years): Type III collagen replaced by type I collagen, scar matures, blood vessels regress. Scar initially red/pink, gradually fading to pale
Types of Scars
| Scar Type | Characteristics | Treatment Approach |
|---|---|---|
| Normal (fine-line) | Flat, pale, flexible. The ideal surgical outcome | Silicone, SPF, time |
| Hypertrophic | Raised, red, stays within wound boundaries | Silicone, steroid injections, laser, pressure |
| Keloid | Raised, extends beyond wound boundaries, itchy | Steroid injections, 5-FU, silicone, surgery + adjuvant |
| Atrophic | Depressed, indented (e.g., after acne or chicken pox) | Microneedling, filler, laser, subcision |
| Contracture | Tight, restricts movement (common after burns) | Surgery, physiotherapy, laser, silicone |
| Stretched (wide) | Wide, flat, pale scar due to tension on healing wound | Revision surgery, laser, microneedling |
Timeline-Based Scar Management Protocol
Phase 1: Immediate Post-Operative (0–2 Weeks)
- Follow surgeon’s wound care instructions precisely
- Keep the wound clean and moist (petroleum jelly or antibiotic ointment as directed)
- Avoid tension on the wound (no heavy lifting, stretching)
- Do not remove sutures or dressings prematurely
Phase 2: Early Scar Care (2–6 Weeks)
- Silicone-based products: Begin silicone sheets or gel once sutures are removed and the wound is fully closed. The gold standard for scar prevention with strong evidence (Grade A recommendation in international scar guidelines)
- Sun protection: SPF 50 over the scar whenever exposed. UV exposure causes permanent hyperpigmentation of immature scars
- Massage: Gentle scar massage 2–3 times daily (once wound is fully healed) improves collagen alignment and reduces adhesions
Phase 3: Active Treatment (6 Weeks–6 Months)
- Microneedling: Starting at 6–8 weeks post-surgery. 3–6 sessions, 4 weeks apart. Breaks down disorganised collagen and stimulates organised remodelling
- Pulsed dye laser (595nm): Reduces scar redness and vascularity. 2–3 sessions, 4–6 weeks apart. Can flatten mildly hypertrophic scars
- Steroid injections (triamcinolone): For hypertrophic or keloid scars. Reduces collagen overproduction and inflammation. Monthly injections until flat
- Pressure therapy: Custom pressure garments for large surgical scars (particularly post-burn)
Phase 4: Mature Scar Improvement (6 Months–2+ Years)
- Fractional laser resurfacing: CO2 fractional or erbium fractional laser creates micro-columns of damage that promote collagen remodelling. 2–4 sessions. Cost: £300–£800 per session
- RF microneedling: Morpheus8 or similar for scar texture improvement and collagen remodelling
- Subcision: For tethered or depressed scars — a needle is used to release scar tissue from underlying structures
- Filler: HA or biostimulatory filler injected beneath depressed scars to elevate them
- Scar revision surgery: For significantly unfavourable scars — excision and careful re-closure under minimal tension
Expert Insight
“The most common mistake we see is patients doing nothing about their scars in the early weeks, then seeking treatment when the scar is already mature and harder to modify. Early intervention — starting silicone therapy at 2 weeks and professional treatment at 6–8 weeks — produces dramatically better outcomes than waiting until the scar is fully mature. If you are planning surgery, ask us about a pre-planned scar management protocol.”

Frequently Asked Questions
When should I start treating a surgical scar?
Begin silicone therapy and sun protection as soon as sutures are removed and the wound is fully closed (typically 2 weeks post-surgery). Professional treatments like microneedling can begin at 6–8 weeks once the wound is stable and the initial inflammatory phase is complete. Laser treatment for redness can start at 4–8 weeks. Earlier intervention generally produces better outcomes. Book a scar assessment at Axiom Aesthetics as soon as your sutures are out.
Can old scars be improved?
Yes. While mature scars (older than 12–18 months) are more challenging to treat than fresh scars, significant improvement is still achievable. Fractional laser resurfacing, RF microneedling, and microneedling can remodel the collagen structure of mature scars. Depressed scars can be elevated with subcision and filler. Hyperpigmented scars respond to laser and topical treatments. Even scars decades old can show meaningful improvement with modern techniques. Results typically require 3–6 treatment sessions and realistic expectations about the degree of improvement.
Do silicone scar sheets really work?
Yes — silicone therapy has the strongest evidence base of any topical scar treatment. International scar management guidelines give silicone sheets and gel a Grade A recommendation (highest level). The mechanism involves hydration of the stratum corneum, regulation of fibroblast activity, and reduction of excessive collagen production. Studies consistently show that silicone sheets reduce scar height, redness, and hardness when used for 12+ hours daily over 3–6 months. They are effective for both prevention and treatment of hypertrophic and keloid scars.
I am prone to keloid scars — can anything be done?
Yes, though keloid management requires a proactive, multi-modal approach. First-line treatment is intralesional steroid injection (triamcinolone), which reduces collagen overproduction. For resistant keloids, combination therapy with steroid + 5-fluorouracil has good evidence. Silicone sheets should be used continuously. Pressure therapy helps in suitable areas. For keloid removal, surgical excision combined with immediate adjuvant treatment (steroid injection, radiotherapy, or silicone) reduces recurrence rates from 50–80% (surgery alone) to 10–20%. Contact us for keloid management advice.
How much improvement can I expect from scar treatment?
Results vary significantly based on scar type, age, location, and individual healing characteristics. For fresh surgical scars treated early, improvement of 50–80% in redness, texture, and height is realistic with a comprehensive protocol. For mature scars, 30–60% improvement in texture and appearance is a reasonable expectation with multiple treatment sessions. Complete scar removal is generally not possible with any treatment — the goal is making the scar significantly less noticeable and more comfortable. We set honest expectations during consultation at Axiom Aesthetics.
