33 y/o female - what nonsurgical options would help minimize the appearance of cheek wrinkles? (photo)

Fine lines like this can definitely be improved but usually require a few treatments with different modalities, because they are the result of muscle movements that you aren't going to stop making! You're already doing microneedling, which is great. A thin, low density, and flexible filler like RHA Redensity is very helpful to add back lost volume. Nanofat or PRP injections can help improve skin quality, as well. I don't like Ultherapy for a number of reasons, but an RF microneedling like Morpheus8 can be helpful for these, too, typically after a few treatments and in conjunction with the other treatments above.

Microneedling, which I have been performing for over twenty-three years, is best reserved for improving very superficial, surface texture and color irregularities. It would not be expected to be of much use with this type of issue. And, you are quite on the mark in exercising "beware beware" caution when considering the expensive, here-today-gone tomorrow RF gizmos that are being hawked out there, since the hard science to back up their use lags woefully behind the heavy marketing hype and social media buzz to promote them. I have had very gratifying results with precisely this kind of problem with using appropriately injected low viscosity, malleable and cohesive HA fillers. You would be wise to consult with an experienced, board certified cosmetic dermatologist filler expert and best of luck

For unique cases where a variety of modalities could be used to treat the condition, I would suggest an in-person or virtual consultation to develop a custom and effective treatment plan. It is difficult to precisely define the best option without collecting the same information. I suggest reaching out to an expert for a consultation with surgical and non-surgical methods to get a comprehensive option. Best, Dr. Emer.
