Please tell me about lifting wrinkles on my arms!

Hello!!! My mom has been taking great care of her skin lately, after seeing me looking in the mirror. Haha. She said she's worried that her nasolabial folds have gotten too deep. Is there any good nasolabial fold lifting procedure that people in their 50s can do? If so, I'd like to hear about something that's effective for nasolabial fold lifting!!!! Please also let me know how many nasolabial fold lifting procedures I need to get to see results. Thank you~~~!
