Any suggestions for horizontal line across nose right between eyes? (photos)

Thank you for your question.  Horizontal lines at the upper part of the nose and lower part of the forehead are caused by the actions of the procerus muscle.  It runs vertically along this area and is responsible for pulling the skin between the eyes downward.  A wrinkle relaxer, such as Botox is an excellent treatment to remove these lines by preventing the muscle from working.  See a board certified plastic surgeon who can help you treat this area.  

Dear roses133:Thanks for sharing your photos. With a history of using Retin-A and no improvement in the quality of the fold or pigmentation, this maybe a shadow. Proper use of Botox or fillers may help lift and / or fill the horizontal fold you present.It is best to be evaluated by a well experienced, Board Certified Plastic Surgeon or ENT Facial surgeon well versed in all these techniques to provide a better recommendation for you. All the best!
