Thanks for your question! The difference is the depth and the recovery. The nano laser peel is less than 10 microns deep and a micro laser peel is 10-100 microns deep. Both treatments will help with skin texture, while the microlaser peel is also able to remove superficial sun damage from the skin. The deeper the peel, the longer the recovery, but you have more significant improvement with deeper peels.With a nano peel you may be red for 12-24 hours, like a sunburn. With Micro laser peel you may be red for up to 10 days depending on who deeply you are treated. If you don't want that much downtime, you can repeat a Nano Peel monthly with mild-moderate improvement. Good luck to you!
