What are the chances of getting side effects from steroids injection for facial scar? we better do or not?

Risk vs Benefit: Steriods are injected into scar to help flatten them. The risks and benefits with avry from patient to patient, so you should go over them with your doctor. Systemic side effects are rare. Local problems include, but are not limited to, no effect, infection, discoloration, loss of pigmentation, atrophy and scar widening.

Steroid injections: I have used kenalog (triamcinolone) injections for scar control for several years - you need to be careful about how much steroid your doctor uses in each injection. Steroids like kenalog (triamcinolone) can cause fat atrophy beneath the skin. I generally inject kenalog (triamcinolone) in 10 mg/ml doses directly into scars. Steroid injections will not improve the appearance of widened and stretched scars.

Thinning of skin : Common side effects include pain and injection site irritation. Perhaps the most concerning side effect is thinning of the skin (atrophy) where the steroid is injected. A well-trained facial plastic surgeon will know what strength of steroid to use in order to limit the chances of this from happening.
