HI, if you consulted in our office and were over 18, we would recommend filler to your cheeks and under your eyes to give you some volume where that is lacking. Hereditary bone structure for some ethnicities is such that to make cheeks look fuller and thus change your genetic look you need volume. A solid cheek implant could be used, but I like filler because it can be placed exactly where you need it. Fat is the longest lasting and works well in you situation. At 14, you will need a parent's consent.
You are a little young to be worrying about the bags under your eyes. I would suggest seeing a dermatologist or plastic surgeon who specializes in eye surgery/treatments like we do. At your age some topical creams are useful. If genetically your lower eye bags are more prominent, you will need surgery and/or filler in the future. But you are underage, and it would be best to wait till you are 18 to decide on these types of decisions, unless your parents are willing to support you through it. I wish you the best of luck, Dr. Emer.
