Unfortunately, there just isn't a magical skincare regimen or a specific product that will replace or exactly replicate the effect of filler. That said, preventative skincare (aka what you're doing now!)
"Many of the aging changes that people seek filler to correct are caused by sun damage," Samolitis points out to me. "Although most people consider sun damage to primarily cause dullness and discoloration, it also causes loss of skin thickness and volume of underlying fat." Instead of (or in addition to) fillers, Samolitis suggests treating the underlying sun damage with skincare in tandem with skin-rejuvenating procedures like peels, micro-needling, laser resurfacing, regular facials, etc. Again, your derm will be able to advise a strategy and treatment plan that will be best for your personal goals.
As Ronald Moy, MD, FAAD, of Moy Fincher Chipps explains, Botox/Dysport/Xeomin/Jeuveau will better for treating things like frown-line and crow's-feet wrinkles, whereas rejuvenating and tightening procedures like radio frequency skin tightening or carbon dioxide laser resurfacing can yield better, longer-lasting results for the skin under the eyes. Ahead, we're listing all of the best filler alternatives, according to Engelman, Herrmann, Moy, and Samolitis.
