Long thin face with flat cheeks and shallow but permenant nasolabial fold

Eye bags likely can't get better with creams. Fat grafting and Sculptra are both excellent options depending on your preference, anatomy, and location of aging process. You need to have a full facial rejuvenation consultation and evaluation to determine what's best for you.

If you are looking for more volume in the face, I
recommend consulting about Sculptra. During the aging process we tend to lose
volume, Sculptra will stimulate collagen helping to replenish lost volume.
Sculptra can restore a more youthful, natural look that lasts more than 2
years.

You should be seen by an advanced filler injector and board-certified dermatologist or plastic surgeon. There are additional questions that need to be asked and answered, and it ks important to actually see you to see what is going on.Either option would be beneficial.  If you have become thin because of loss of fat, fat injections may be the best option for you. Have you lost weight overall? Do you plan to gain some weight in the near future? Sculptra lasts more than two years, and in my experience, the duration of fat injections is variable, and dependent also upon the amount injected and the processing of the fat before injected.  Fillers can help nasolabial folds and tear troughs. However, eye bags are a complex issue. There are many different causes and therefore many potential solutions. This is one of those situations where a consultation is in order!
