Is skin ultimately something you're born with? 🤔

While looking up various skincare tips lately, it suddenly occurred to me: is genetics really a big part of skin condition?
Even if we stay up all night together and live similar lifestyles, some people always have clear skin, while for others, even the slightest lapse in care shows immediately, right?

I do drink plenty of water and take care of my skin to some extent, but since things like my pores and texture don't seem to change easily, sometimes I wonder if it's ultimately something you're born with... I feel like I'm noticing it as much as I get older 😅 Haha

Of course, I know consistent care is important, but I'm curious whether those whose skin has actually improved relied more on their lifestyle habits or if they received significant help from treatments or products. What do you all think? 🙂
