Thanks for your question, KayAllen! Depending on the placement and kind of sagging skin you have, PICO Genesis may be able to somewhat diminish the appearance of loose skin. The PICO Genesis treatment helps stimulate collagen production, which can restore volume and structure to your skin. The PICO Genesis laser is primarily designed to help with age spots, acne and wrinkles on the face, though, so if your concerns are located under the chin or on the neck you may want to explore other treatment options. There are several methods designed for tightening loose skin on the neck, including ultrasound therapies and neck lifts. You should schedule a consultation with an experienced plastic surgeon in your area to find out what kind of treatment might give you the best results. I hope this helps!
