I'm 18 and i have eyebags, wrinkles around lower lid. (photos)

Not making them are abnormal and actually suggests that you are making a phony smile if there are no line lines around the eyes.  You would benefit from under eye hyaluronic acid filler.  These treatments can last over a year.  Look for an expert injector and make sure you know precisely what your are being injected with.  In my opinion Restylane is the best product for this.

The wrinkles you refer to are normal. However, if they bother you, the under-eye area can be smoothed out with fillers. Please send an expert if you want treatment. Best, Dr. Emer

Thank you for your question. Eyelid surgery can address those marks on the upper eyelid crease. The 'pinch technique' can remove the excess skin on the outside of the upper eyelid and allowing the incision to conform to the natural contour of the eye and become hidden in the eyelid fold. I suggest that you consult with a board certified facial plastic surgeon at an in-person appointment.

Best wishes,
