right so I've been stripping my routine back

Honestly the biggest mistake I made last March was just... carrying on with the same heavy stuff I was using in January. My skin basically revolted. That tight, congested feeling around my nose and forehead — that was me not paying attention to the fact that it was getting warmer and my skin didn't need as much. Basically what I do now is swap out the thicker moisturiser once I stop needing the heating on constantly. Nothing dramatic, just lighter. And I cut back how often I use the collagen powder too — not because of any particular reason, I just drink more water naturally when it's warmer so my skin seems to handle things better on its own. Less is genuinely more when the seasons shift, I reckon. My lads' routine is four products max anyway so there's not much to overthink, but even within that there's room to ease off. Mind you it took me two years of bad skin in spring to figure this out so.
