Dry skin does not mean skipping SPF. It means choosing the right one. Many sunscreens are formulated for oily or combination skin, using lightweight gels and high-alcohol bases that can leave dry skin feeling tight, flaky, or uncomfortable. The good news?

In this guide, we break down exactly what to look for in an SPF for dry skin - from barrier-supporting ingredients like Polyglutamic Acid, Glycerin, and Squalane to the textures and formulas best avoided - plus how to layer your routine correctly for hydrated, protected skin every day.
