Hi, Has anyone experienced the long-term effects of the light treatments? I have purchased a Prolight at home device. Only used it on my face 4 times over four weeks. It has been now about 15 days since my last treatment. I think my skin looks definitely more saggy then it did before I started using it. While I looked great the day after each treatment, I kind of feel like it was a pulling effect that initially tightened the skin, and then when it wore off, it is now looser. Has anyone tried this, either at home or professional treatments, and then stopped for a little while and compared the results? Any insight??! Thanks!
