it's not just about drinking more water

Right so I already posted about plain water a few days ago and I don't want to repeat myself, but there's a slightly different angle I've been thinking about that I didn't cover. Hydration for skin isn't really one thing. I mean there's how much water you drink, yeah, but there's also whether your skin can actually hold onto moisture — which is a completely separate issue. I'm not a dermatologist but from everything I've read over the years, that's where ingredients like hyaluronic acid and ceramides come in. They're not adding water, they're basically helping your skin barrier not lose what's already there. Transepidermal water loss is the term, if you want to go down that rabbit hole. I did. Don't recommend it at 11pm. What actually shifted things for me wasn't changing my water intake — it was adding a hydrating toner (an essence really, very K-beauty of me I know) before my serum. Thin layers, slightly damp skin, let each one sink in. My skin started feeling less tight by mid-afternoon which used to be a thing for me especially in winter with the heating on constantly. Central heating is genuinely the enemy. I also think collagen plays into this more than people expect — I've been taking mine daily for a while now and I do think it's helped with that sort of plump, bouncy quality the skin has when it's properly hydrated from within. Hard to isolate obviously, too many variables, but the timing lines up for me.
