Detailed answer

Face rollers can help improve the appearance of sagging skin temporarily. They work by stimulating blood circulation and lymphatic flow, which can reduce puffiness and promote a temporary tightening effect. However, face rollers cannot provide long-lasting or permanent improvement to sagging skin. For more significant and lasting results, other treatments such as dermal fillers, radiofrequency, or surgical procedures may be necessary. It's important to consult with a skincare professional or dermatologist to determine the most suitable treatment options based on your specific needs and degree of sagging skin.
