hydration is doing more than SPF alone was

Right so I've been pretty consistent with sunscreen all summer (finally) but my skin still felt a bit dull and tight by end of day. Started actually drinking proper amounts of water again — I mean I thought I was but I really wasn't — and adding collagen to my mousse in the evenings, not for any dramatic reason just it was easy to slot in. Two weeks on and honestly the tightness has mostly gone. My mum poked my cheek the other day and went "you look well" which from her is basically a glowing review. I don't fully understand the science of it tbh, I just know it's working for me.
