What can I do to improve two sets of smile lines? (photos)

The outer lines you are referring to are known as nasolabial folds and they frequently appear with the smile lines in the corners of the mouth. Both of these folds can be treated using injectable dermal fillers. The filler is administered into the dermal tissue to restore support and smooth away the lines from the inside out. I encourage you to schedule an in-person assessment with a board-certified dermatologist who has expertise in dermal filler treatments. A qualified provider should be able to help you achieve very good results. 

folds can be Improved with fillers, threads, and morpheus tightening. at home dermarolling and peels like enlighten can help (see link to emeragecosmetics.com for link to rolling protocols).
For facial rejuvenation, 
1) skin care with products and PRP/microneedling
2) PDT light therapy few times a month with growth factors
3) laser treatments like clear and brilliant regularly and a few times a year Fraxel/halo Viva, Co2/Erbium
4) Sculptra injections a few times a year for collagen production with fillers like juvederm/restylane/belotero/radiesse/bellafill
5) thermage/ultherapy for yearly skin tightening with or without PDO or cone based instalift threads for lifting
6) botox every 2-3 months to stop movement lines and prevent lines at rest
7) deep microneedling RF like Fractora/morpheus8 for tightening of the skin
8) Vascular laser like vbeam/excel V or BBL forever young treatment every quarter (3-4 months)
Best, Dr. Emer.

A collagen stimulating filler like Sculptra Aesthetic should help with the volume loss. The laugh lines themselves could then be injected with an HA gel filler like Restylane Refyne or Restylane Defyne. 

Hello and thanks for your question. Fillers would be a good option here to help soften these folds based on the photos you have sent. We would also consider energy based devices such as radiofrequency and ultracel to lift the face. The best option would be to seek a face to face consult with an experienced doctor for a more detailed treatment plan. Best wishes
