The body possesses a naturally occurring molecule and moisturizing component known as hyaluronic acid. Acting as an internal moisturizer, hyaluronic acid gives skin a smooth and supple appearance. As we age, the presence of hyaluronic acid diminishes, causing wrinkles to appear more prominent. Dermal fillers utilize hyaluronic acid to add youthful volume to areas of the face including lips, cheeks, chin, smile lines, under eyes, or jawline.
