Women who are always mistaken for being younger than their age, what's your secret?

I’m in my 30s and looking for some tips on maintaining a youthful appearance. I often see women who seem to defy aging, and I’m curious—what’s your secret?

Is it skincare, hydration, diet, sunscreen, genetics, or something else entirely? Are there any specific habits, products, or lifestyle choices that have made a noticeable difference for you?

I’d love to hear any advice, things you swear by, or even mistakes to avoid. Spill your secrets!

Edit: Wow, I did not expect this post to blow up! Thank you all for sharing your tips, routines, and insights. I’m truly appreciating every response and taking notes. I may not be able to reply to everyone, but I’m reading them all! Y’all are incredible! ❤️
