Three-Phase Scar Protocol
Surgical scars pass through three biologically distinct phases. Each phase calls for a different management focus — the same product used in the wrong phase either does nothing or causes harm. The protocol below applies to all cosmetic surgical incisions; body procedures (abdominoplasty, breast lift, liposuction entry sites) require longer active treatment than facial procedures (rhinoplasty, eyelid, lip lift) because body skin is thicker and under greater mechanical tension.
| Phase | Scar Appearance | Treatment Protocol | What to Avoid |
|---|---|---|---|
| Phase 1 — Active (Weeks 1–12) | Pink to red; slightly raised; may itch. Wound is closed but collagen is disorganised. | Silicone gel or sheet twice daily from suture removal. SPF 50+ on all sun-exposed scars daily. Keep incision moisturised; avoid tension on wound edges. | Sun exposure without SPF. Vitamin E oil, essential oils, or non-silicone 'scar creams'. Picking crusts or scabs. Swimming pools (chlorine) until fully closed. |
| Phase 2 — Remodelling (Months 3–12) | Colour fading from red toward pink or skin-tone. Texture softening. May still be slightly raised. | Continue silicone for body scars to month 6. Introduce SPF-containing makeup or concealer on facial scars from month 3. If hypertrophic: steroid injection or laser at dermatologist or plastic surgeon. | Abandoning silicone at first sign of improvement. Heavy exfoliation directly on scar. Prolonged sun exposure without protection. |
| Phase 3 — Mature (Month 12+) | Pale, flat, soft. Scar is clinically mature — further spontaneous change is minimal. | SPF maintenance on pigment-prone individuals. Resurfacing laser or microneedling if texture or pigment remains a concern. No active silicone required. | Expecting further spontaneous improvement without intervention. Fractionated laser before scar is fully mature (pre-12 months) without specialist guidance. |
The most common deviation from this protocol is patients stopping silicone at week 4–6 when the scar looks “fine” — the remodelling phase continues to month 12 regardless of surface appearance.
Silicone Gel vs Silicone Sheets: Which to Use
Both silicone gel and silicone sheets work by the same mechanism — they create a semi-occlusive (partially sealed) environment over the healing wound that regulates moisture loss and suppresses overactive fibroblast activity. Fibroblasts are the cells responsible for collagen production; overstimulation produces raised, hard scar tissue.
The choice between formats is anatomical rather than clinical:
Silicone gel suits contoured surfaces — the nasal tip after rhinoplasty, the lip border after lip lift, eyelid creases, or any area where a flat sheet cannot maintain contact. Apply a thin layer twice daily; allow 4–5 minutes to dry before applying SPF or makeup.
Silicone sheets suit flat, accessible surfaces where they can be held in contact for several hours — the lower abdomen after abdominoplasty, the lateral chest after breast surgery, or the upper thigh. Sheets are typically worn 12 hours daily and can be washed and reused for 2–4 weeks before replacement.
There is no evidence that combining gel and sheets outperforms either used correctly and consistently. If one format causes skin irritation — a common issue with sheets in humid Korean summers — switch to the other rather than discontinuing silicone entirely.
Neither format requires a prescription. Both Kelo-cote and Dermatix gel are available over the counter at Olive Young (올리브영, a Korean pharmacy and beauty chain) locations across Seoul.
Identifying and Treating Hypertrophic Response Early
Hypertrophic scar (비후성 반흔, bihuseong banheum) is scar tissue that becomes raised, red, and thickened but stays within the original wound boundary. It differs from a keloid, where scar tissue extends beyond the wound edge into surrounding skin. Hypertrophic response occurs in approximately 30–70% of body surgical scars and is driven by mechanical tension, infection, and individual genetic predisposition.
The clinical window for early intervention is weeks 4–12. A scar that is getting harder, more raised, and redder week-on-week — rather than gradually softening and fading — is showing a hypertrophic response. At this stage, intralesional triamcinolone (a corticosteroid injected directly into the scar tissue) suppresses fibroblast overactivity and significantly reduces scar volume. The same injection at month 6 is considerably less effective because the collagen has consolidated.
Signs that indicate you should contact your Korean clinic or a local plastic surgeon promptly:
- Scar is measurably thicker at week 8 than at week 4
- Persistent itch or burning sensation extending beyond week 6
- Scar width is expanding laterally
- Redness intensifying rather than fading
Patients with darker Fitzpatrick skin tones (IV–VI) — common across East Asian, Southeast Asian, and South Asian populations — carry higher baseline risk for both hypertrophic scar and keloid. If this applies to you, discuss prophylactic steroid at closure with your surgeon before the procedure, and begin silicone from the earliest possible date after suture removal.
When Laser Scar Treatment Is Appropriate
Laser treatment for surgical scars is not a first-line intervention — it is used when the scar has either matured poorly after standard silicone and SPF management, or when a hypertrophic response has been stabilised with steroid injections and residual texture or colour remains.
Two laser categories are relevant:
Vascular lasers (pulsed dye laser, Nd:YAG) target the blood vessels that give hypertrophic scars their persistent red colour. These are appropriate from months 3–6 on a stable scar that is no longer actively thickening.
Fractional resurfacing lasers (CO₂ or Er:YAG fractional) remodel collagen texture and address surface irregularity. These are used on mature scars from month 12 onward — using fractional resurfacing on an immature scar can stimulate rather than suppress fibroblast activity.
Korean aesthetic clinics offer both categories. If you are returning home after surgery, any qualified dermatologist or plastic surgeon with laser capability in your home country can perform these treatments — the procedure is not Korea-specific. Confirm that the scar is fully mature and that any hypertrophic response has been controlled before proceeding with fractional resurfacing.
How long do I need to use silicone gel on my scar after Korea surgery?
Minimum 3 months of consistent daily application — twice daily, every day, starting from suture removal. Many scar specialists recommend 6 months for body scars (abdominoplasty, breast lift, liposuction). For facial scars (rhinoplasty incisions, lip lift, eyelid), 3 months is usually sufficient. Inconsistent use is significantly less effective — missing multiple days per week reduces the clinical benefit substantially.
What silicone scar products can I buy in Seoul?
Olive Young (올리브영) pharmacies in Gangnam stock Kelo-cote and Dermatix silicone gels, both well-evidenced products. Korean domestic brands including Cicaplast are also stocked, though these are not silicone-based and not recommended as primary scar treatment. Your clinic's discharge kit may include silicone gel — if not, buy at Olive Young before your flight home. Silicone sheets are harder to find at pharmacies; order online or ask your clinic if they stock them.
My scar is getting raised and red at week 6 — is this normal?
A mild red, slightly raised scar at week 6 is within normal healing range — this is the active remodelling phase. However, if the scar is thickening week-on-week rather than gradually flattening, this is a hypertrophic response that benefits from early intervention. Intralesional steroid injection at weeks 6–8 is far more effective than at week 20. Contact your Korean clinic or a local plastic surgeon promptly if it is actively worsening.
