I am a 43 year old female and have recently given up smoking after 25 years. I have now, over the years developed fine lines around my mouth especially at the corners of my mouth and chin. The lines are not deep although are very noticeable. Is this caused by the smoking action of the lower part of the face? Could you please advise me on the best method to rid these embarassing lines. Is a topical cream a successful option and if so, which one or do I require non invasive procedure. I would love your opinion.
