Dear Silvasda, Since there was no photo attached to your question, I am going to make an assumption that the lines around your mouth that you are desiring to treat are the ones that form on the upper lip and around the corners of your mouth. These types of lines for the most part will not respond to Botox-which is a paralytic agent in that it weakens the muscles under the skin-and instead are usually treated best with a filler material. Think of it this way, there are essentially three types of lines on our faces: 1-thin, shallow crinkled rice paper lines that are on the surface of our skin. These are usually environmental in cause (sun, etc.) and are best treated with some combination of resurfacing, peeling, and skin management. 2-wrinkles and lines caused by aging as tissues deflate, migrate, etc. These are best treated with fillers and surgery. 3-wrinkles caused by the constant action of our facial muscles that cause the skin about them to develop crease and folds with time and aging. These are best treated with agents such as Botox or Dysport. From what you are describing, it sounds a filler or fillers would be the best choice of treatment but only a consultation with a qualified board-certified doctor can answer your questions accurately. Good Luck.
