Thank you for sharing your question. Although five months have passed since your laser treatment, you might still see improvements for up to a year. Steroids and microneedling with PRP might be beneficial. Make sure to wear sunblock and sunglasses outdoors to avoid worsening of the scar.
there are many options for treatment including lasers, microneedling/PRP and steroid injections. I suggest you see an expert for treatment options. Best, Dr. Emer.
