Sun protection isn’t just for summer or beach trips — it’s the most important skincare step you can take every single day. Ultraviolet (UV) rays from the sun are present even when it’s cloudy or when you’re indoors near windows. With regular exposure, these rays quietly contribute to dark spots, uneven tone, fine lines, and early signs of aging. That’s why making a sunscreen part of your daily routine is essential for maintaining healthy, resilient skin.
