hyperpigmentation from alexandrite

About 3 weeks after treatment I’m noticing a couple of hyperpigmented spots on my legs. They are not very big or very dark. Would a fade cream like hydroquinone fix that? Do I need to be concerned about future treatments?

what is your skin type? what settings were used? you should tell your tech so they can decrease the settings a bit. also, do you have a tan at all? if you can avoid all sun and/or tanning and be as white as possible for your following treatments, that you help you as well.
