I've had four steroid injections for my scar, but the keloid has grown again. What's going on?

In general, after receiving four injections for scar treatment, the recurrence of keloids may be caused by factors such as insufficient drug dosage, patient insensitivity to the medication, poor quality of the scar injection, incorrect injection site selection, or inadequate daily care after the injection. The specific analysis is as follows:

1. Insufficient drug dosage: If the dosage of medication used by the doctor is too low, it may fail to effectively suppress the growth of scar tissue, leading to recurrent keloid formation.

2. Patient insensitivity to the medication: Some patients may have limited sensitivity to drugs such as corticosteroids. This means that even with an appropriate dosage, the therapeutic effect may still be limited, resulting in recurring keloids.

3. Poor quality of the scar injection: If the scar injection used is of poor quality, it may lead to uneven distribution of the drug, thereby causing frequent recurrence of keloids.

4. Incorrect injection site selection: The scar injection must be accurately delivered into the scar tissue to ensure the medication reaches the targeted area. If the injection site is incorrectly chosen, the drug may not achieve its intended effect.

5. Inadequate daily care after injection: Proper daily care following a scar injection is crucial. This includes keeping the injection site clean and avoiding friction or irritation. Failure to maintain proper aftercare may result in frequent recurrence of keloids.

If keloids reappear, it is recommended to seek medical treatment promptly to avoid delaying the condition.
