Dermal fillers are injectables that use either natural or synthetic hyaluronic acid to plump up your skin. In contrast to neuromodulators, dermal fillers create volume and fullness which achieve a natural, youthful appearance and fill in thin lips, hollows around the eyes, or gauntness in your temples. The results with dermal fillers are instantaneous and long-lasting (three months to two years). We often use dermal fillers in combination with neuromodulators to achieve the best results since they each have different strengths.
