38 years old - What would be the most effective treatment for smile lines, other than fillers? (Photo)

I’m 38 and have used tretinoin and sunscreen since my early 20s. 10 years ago these smile lined started showing and got worse about 3 years ago. I had Voluma on my cheeks but it made no difference to the lines. The lines are getting more pronounced and I would like to avoid fillers. I’m after a treatment that is effective but not a facelift yet. I’ve heard about Ultraformer, ultherapy, microneedling and lasers but it’s hard to find unbiased information. What would you suggest?
