Volbella is a very thin and natural looking/feeling hyaluronic acid filler that does a wonderful job in filling out the perioral lines that develop due to smoking and age. However, it would only be effective on shallow wrinkles.The amount required is determined by the degree of wrinkling, skin type, age, and specific anatomy of the area which all requires a detailed assessment in order to generate the perfectly tailored plan for each individual.Other treatments that may help that area in combination with Volbella include laser treatment to stimulate more collagen and Botox to relax the muscles that cause wrinkling. If the wrinkles and folds are deep, Restylane Defyne or Reyne would be a better choice.Consulting with a board-certified dermatologist will solve the issue for you.
