The answer is nuanced; injections can't entirely remove all scars, but they can significantly reduce their size and prevent certain types from forming.
How Injections Help with Scars
Injections, specifically steroid injections, play a role in scar management, particularly for hypertrophic scars and keloids. They work by:
- Reducing Inflammation: Steroids reduce inflammation in the scar tissue, leading to a flatter and less noticeable appearance.
- Preventing Scar Formation: According to provided references, "Presurgical steroid injections may prevent a hypertrophic scar or keloid from forming—or they may reduce the scar's size." This means that if you have a history of these types of scars, your doctor might inject steroids before surgery to minimize or prevent their development.
Types of Scars Addressed by Injections
The reference primarily focuses on hypertrophic scars and keloids. Let's clarify what these are:
| Scar Type | Description |
|---|---|
| Hypertrophic Scars | Raised scars that stay within the boundaries of the original wound. |
| Keloids | Raised scars that grow beyond the boundaries of the original wound. |
Important Considerations
- Not a Universal Solution: Injections are not a guaranteed fix for all types of scars. Other treatment options might be necessary depending on the scar's nature, location, and severity.
- Pre-Surgical Use: Injections are most effective when used preventatively before surgery, especially for individuals prone to hypertrophic scars or keloids.
