Ottawa's continental climate brings extreme seasonal variation that directly affects skin health. Winter brings dry indoor heating and cold outdoor air that strips moisture. Spring and fall bring rapid barometric swings as weather systems pass through the Ottawa Valley. Summer brings high UV levels and, increasingly, wildfire smoke from northern Ontario and Quebec.
Understanding these patterns helps you adapt your skincare routine proactively rather than reactively. If you are noticing changes in your skin tied to weather patterns, a consultation can help build a plan tailored to your skin's response to Ottawa's unique environment.
