Hello Sohek,Lasers do a great job helping to tighten the skin. However, for under eye bags they would not be the recommended treatment (they can help of you have crepey skin under the eyes). For treatment of eye bags the recommendation would be either surgery to remove the bags plus or minus fat repositioning or transfer or using fillers to camouflage the shadow created by the bag.I'd recommend you consult with a facial plastic surgeon for an in person evaluation to go over the options. I hope this helps and good luck.
