Choosing the Right Scar Gel for Surgery — What the Science Says
How to evaluate post-surgical scar care: mechanisms, ingredients, and clinical evidence
The clinical principle
Scar quality is determined by what happens during the remodelling phase — weeks to months after surgery. The right product supports this process from the surface.
REVAGI The Recombinant Serum provides recombinant collagen support for the sub-dermal remodelling phase — used at licensed aesthetic clinics in Singapore.
The Science of Scar Formation
All surgical scars form through the same four-phase process: haemostasis, inflammation, proliferation, and remodelling. The final scar quality — its texture, height, width, and colour — is determined by the remodelling phase, which continues for 12–24 months post-surgery.
During remodelling, Type III collagen (the early scaffold) is progressively replaced by stronger Type I collagen. If fibroblast activity is excessive or disorganised, the result is hypertrophic or widened scarring. Supporting organised collagen synthesis during this phase is the core goal of scar gel therapy.

Types of Scar Gel — What Each Does
| Type | Mechanism | Evidence base |
|---|---|---|
| Silicone gel | Occlusive layer, TEWL regulation, moisture retention | Strong — well-studied for hypertrophic scar prevention |
| Onion extract (allantoin) | Anti-inflammatory, softening | Moderate — some evidence for scar texture |
| Vitamin E | Antioxidant, hydration | Weak — limited clinical evidence for scar outcomes |
| Recombinant collagen | Biomimetic layer, fibroblast regulation, anti-inflammatory modulation | Strong — published evidence for post-procedure applications |
What to Look For — and What to Avoid
- Look for: products with published clinical evidence for post-surgical or post-procedure use; fragrance-free; no irritating actives on healing tissue; recombinant or biocompatible collagen
- Avoid: products with fragrance, alcohol, or AHAs on healing surgical wounds; products not tested for post-procedure use; anything applied before the wound is fully closed
When to Start and How Long to Continue
- Only after the wound is fully closed and cleared by your surgeon — typically 2–6 weeks post-surgery depending on procedure
- Continue for 6–12 months — the remodelling phase is long
- Apply twice daily, consistently — results require sustained use
- SPF 50+ on all healing skin exposed to sun
