38 & need advice on what to do with these under eye wrinkles? (Photo)

Hello, you have some thin crepe-like texture skin along the lower eyelid, which is very common. It is the thinnest skin in the body and now that the fat has been removed from the lower blepharoplasty you had, the skin needs to be tightened. This can be accomplished with chemical or laser or device resurfacing. Please visit an experienced oculoplastic surgeon for best results.

You have fine skin - this should be correctable with a combination of the right skin care products and possibly light laser resurfacing. That can be done right in the office. Also we should look at what kind of blepharoplasty was done as some can actually make the problem worse.
Overall, all of this should be addressable in the office.
