In short, fillers help to diminish facial lines, restore volume, and add fullness to the face. As we age, we all lose volume in our faces (lips, cheeks, under eyes) as there is generally a loss in subcutaneous fat. As there is less fat, our muscles work closer to the skin, creating deeper smile lines and crows feet. There are other factors that contribute to deeper lines and loss of volume, including sun exposure, lifestyle, and genetics. Cosmetic fillers can literally fill in the areas of volume loss, giving us the appearance of a more youthful face, at a fraction of the cost (and downtime) of “traditional” surgical facelifts.
