Why winter is exactly when people stop wearing sunscreen and exactly when they shouldn't
Cold weather drives sunscreen compliance down at the same time as skin barrier resilience drops, and at high altitudes or on snow, reflected UV exposure can be even more intense — winter is when an SPF habit matters most, not least.
Why sunscreen compliance drops specifically in winter despite ongoing UV exposure
Cold, overcast winter weather creates a strong psychological disconnect from "sun protection weather," leading many people to drop their SPF habit seasonally — even though UV index calculations show meaningful UV exposure continues through winter months, and snow cover can reflect UV radiation back toward the face, increasing exposure in ways summer beach conditions don't typically replicate.
Why winter skin specifically needs a sunscreen that doesn't compound dryness
A standard sunscreen formula that feels fine in summer humidity can feel uncomfortably drying layered onto already winter-dry, barrier-compromised skin — which is part of why winter sunscreen avoidance happens even among people who otherwise maintain good SPF habits, since the discomfort of a drying formula on top of already-dry skin creates a real disincentive.
Choosing a hydrating sunscreen formula specifically suited to maintaining winter SPF habits
A moisturising, birch-juice-infused sunscreen formula addresses the winter-specific problem by adding hydration alongside UV protection, rather than compounding the dryness winter air already causes — removing the discomfort-based disincentive that often drives seasonal sunscreen abandonment and making consistent year-round use more realistic.
