Hello RPW lovelies! <3

I'm 18 and already worried about the wall. What can I do to avoid aging, especially in terms on physical/permanent aging? I know not to drink/party/"live fast die young" stuff, and that the wall will have less of an impact if you didn't spend your 20s relying on your looks alone, but I feel like there's a lot I'm missing. Also, makeup tips? According to RPW theory you want to always look attractive, part of which is wearing makeup, but it's impossible for makeup not to have at least a small effect on skin quality and wrinkles, how does one find the balance?

Thank you and enjoy your day!
