How to manage aging

33F, my face skin is aging badly.

I look much older than I am, and I'm self-conscious because I can clearly see that women my age have much clearer skin than mine. I feel like I'm 10 years older.

I've always eaten a healthy diet, with few processed foods. I've been vegetarian since my twenties, I exercise a lot, and I rarely go out partying.

I know I'm a stressed person, and I grew up in a very sunny part of the world, but I'm still surprised by the state of my skin, and I'd like to counteract that.

I'm not rich, but if you know of any skincare routines, masks or treatments to use, or creams to prioritize, I'd love to hear them.
