After tretinoin injection, the skin may return to normal in about three months; if the lesions are more severe, they may not always return to normal and other methods of treatment should be considered.
Tretinoin injections are glucocorticoid medications that can improve skin inflammation as well as scarring, and can have the effect of softening scars and improving scar tissue. Usually 4 to 6 weeks is a course of treatment, some patients after a course of injections, the scar began to soften and shrink, continue treatment, may be back to flat.
If the patient’s own scar hyperplasia is more serious and the area of the hyperplasia is larger, the scar softening effect of using Tretinoin injection treatment alone is not good, and it cannot be recovered in the long term, and this kind of drug cannot be used for a long time. It is best to remove the hyperplastic scar tissue through surgery.
As each patient’s condition is different, it is recommended that patients seek medical treatment in a timely manner, strictly comply with the doctor’s instructions, do not self-medication.
