Which procedure is recommended to reduce my nasolabial folds? (photo)

Hello, and thank you for providing images along with your question. Based on your photo, you have loss of volume just above your nasolabial folds. By injecting small amounts of filler in this area, the skin will become plump and supple, lifting the skin and smoothing out the visible groove in the skin. I recommend scheduling an in-person consultation with a reputable, experienced injector. Such experts will have the optimal skills, as well as artistry and knowledge of facial aesthetics, harmony, and proportion, helping you achieve the most natural-looking results. During your consultation, your provider will evaluate your skin quality, discuss your concerns and goals, and ensure the best possible outcome.

You appear to have some hollows in the eyelid-cheek junction. This is the next hollow area above the nasoloabial folds. Sometimes filling this area can improve the appearance of the nasolabial folds. A facelift can also help but you may not be ready for that.

Just based on the one photo you provided, you do appear to have some loss of volume in the area below your eyes (above your nasolabial folds). In my opinion, the best way to improve your nasolabial folds would be to add some volume to the area above the folds. This would help to pull back the folds and reduce them.
