Do you have any lifestyle habits that make your skin as elastic as your lower body muscles?

Ultimately, elasticity is everything for both skin and muscles! I was working out my lower body like crazy at the gym just now, and my legs gave out on the stairs and I almost collapsed. But seeing my muscles pump up made me feel so fulfilled and energized. I take such good care of my body, but I'm wondering how I can maintain this plump, firm look for daily habits for my face. I'm trying to avoid salty foods and get a daily lymphatic massage to keep my face from puffing up. What are your secrets? When choosing elasticity-boosting cosmetics, do you pay particular attention to any ingredients? I've heard retinol and collagen are good ingredients, so I'm considering trying them, but I'm a little worried they might irritate my skin. Sleeping position is also really important, so I try not to sleep on my side, but it's easier said than done. Does everyone have their own tips for choosing pillows or tips for getting a good night's sleep to maintain skin elasticity? If you have any tips for tightening open pores after a workout, please share them! If there's a method you've personally tried that you think has great synergy with your lifestyle habits, please let me know!
