Prevention Is Better Than Cure

Post-surgical scar formation is 100 times easier to prevent than treat. Doing the right things during the golden healing period can significantly reduce the chance of scar formation. This article details the correct usage and timing for various scar prevention products.

The Critical Period of Scar Formation

Wound Healing Timeline

Golden Prevention Period

• Most important time: 2 weeks - 6 months post-op

• High-risk period: 1-3 months post-op (scars most likely to become raised)

> 💡 Dr. Liu emphasizes: "Scar prevention must start early. Waiting until the scar has already formed makes treatment much harder. Start from the day of suture removal."

Post-Surgery PRP (Platelet-Rich Plasma) Injection

Frequently Asked Questions

Q1: When can I start using silicone products?

A1: After wound is completely healed:

• 1-2 weeks after suture removal (confirm no discharge)

• Skin surface intact and dry

• No signs of infection

Using too early may trap moisture and cause infection.

Q2: How long should I wear silicone sheets?

A2:

• General recommendation: 12-24 hours daily

• Duration: At least 2-3 months, recommended 6 months

• Keloid-prone: 6-12 months

The earlier you start and the more consistent you are, the better the results.

Q3: Can I use both gel and sheets together?

A3: Yes, but not simultaneously:

• Daytime: Use gel (convenient for going out)

• Nighttime: Use sheets (stronger occlusion)

Or apply gel to edges not covered by sheets.

Q4: Are pharmacy scar products effective?

A4: The key is ingredients:

• Effective: Products containing silicone

• Possibly effective: Onion extract (weak evidence)

• Limited effect: Pure Vitamin E

Check for "Silicone" in ingredients when purchasing.

Q5: How long until I see results?

A5:

Results vary by individual—consistent use is key.
