A good skin routine is always the best start. Cleanse and moisturise twice daily. 
Get a bit more sleep. 
Use a good facial sunscreen. 
Drink plenty of water and eat lots of fruit n veggies.
I have always used the Gretchen Von Thiele anti-wrinkle products. I am using it for the last 6 years as it helped me a lot in reducing my wrinkly skin. Have in mind that it’s not cheap. They are selling it only online at gretchenvonthiele.com
