How to deal with pigmentation such as sunspots?

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.

1)acne scar with crater, firstly, need to assess if the skin has healed well before a gentle subcision of the the crater scar. This is followed by a resurfacing, best by a fractional resurfacing laser. Otherwise a spot chemical peel will do well too. often multiple sessions will be needed for both laser and chemical peels. 2)pigmentation it can be many types of pigmentation, from freckles to Post-inflammatory pigmentation(PIH) to moles. pigment laser work well for freckles, but there is down time for 3-5days. PIH can be treated with nonablative laser and creams.
