What's a life- changing beauty tip you want to shout from the rooftops?

Could be anything. I learned on this sub that you should always wet your face before applying hyaluronic acid… and that’s been a super helpful tip. So just wondered what other advice people have that could help us all? Could be related to anything.

Vitamin C in the morning before SPF and tretinoin at night. I heard this was a gold-standard practise, and have been doing it consistently for 8 months now. My skin has NEVER EVER EVVVVVVEEEERRRRR looked this good! It takes time but omg does it work wonders

And the tip would be that honestly you don’t need much else. Less is more. My skin is much happier with this simpler routine
