my skin does not know what season it is

Honestly this time of year does my head in. It's still cold enough for the heating to be on half the day but then you get that one bright afternoon and suddenly my face is doing something completely different to what it was doing in January. I switched my heavy winter moisturiser out a couple of weeks back — bit too soon, to be fair, ended up with dry patches round my nose for a good week. Rookie error and I should know better by now. What I've actually settled on for spring is just... less. Less product, more water, SPF every morning without fail. I do still use a richer cream at night because Leeds is not exactly balmy in March. The collagen in my morning cuppa is the one thing I've kept consistent all year round, not making any dramatic claims about it but my skin does seem to hold up better when I'm being good about it. That could be the water. Could be the sleep. Who knows tbh. The main thing I'd say is don't swap everything at once. I did that one year, cleared the lot and started fresh, and my skin had an absolute tantrum for a fortnight. Boring advice but: change one thing, give it a couple of weeks, then see.
