Thank you for your question. It is unfortunate that you have more pigmented spots after the laser treatment.
Based on your description, you might have had a Fractional Resurfacing laser like a Fractional CO2.
There is a small risk of Post-Inflammatory Hyperpigmentation (PIH) from these procedures. However, most PIH is temporary and would fade in 4-6 weeks.
I suggest that you schedule an early appointment for review by your doctor so that he can institute early treatments.
There are treatments such as pigmentation creams that should be started earlier rather than later to ensure good outcomes.
Hope that this helps!
Warmest regards,
Dr Justin Boey
