What would be the least invasive option to help me with my nasolabial folds? (Photo)

Fillers and Sculptra would help with your nasolabial folds. As we age, our cheekbones flatten and gravity pulls down the loose skin which causes the nasolabial folds, therefore, it is best to treat the cause first. I would suggest filling the cheeks and temples, then adding to nasolabial folds to soften ( if needed). You are also a great candidate for Sculptra. Sculptra (injectable poly-L-lactic acid) is an injection that stimulates collagen production. It is great for overall facial rejuvenation.

Hello, and thank you for providing images along with your question. While a personal evaluation is necessary, you seem to have loss of volume in the midface, which is a common byproduct of the aging process. 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 around the nose and mouth.

I recommend scheduling an in-person consultation with a reputable board-certified facial plastic surgeon, particularly one with extensive experience with injectables. Such experts will have the optimal skills and techniques, as well as an eye for facial harmony and proportion, helping you achieve your goals, as well as natural-looking results. During your consultation, your surgeon will assess your skin quality and facial profile, customize your treatment plan, and ensure the best possible outcome.

From your photo it appears you would benefit from filler to the cheek area as well as addressing the nasolabial folds. This would improve the volume loss and better balance facial contours. You may consider Sculptra as an alternative for longer lasting results. I've included a video I hope you find helpful.
