Premium sunscreens often contain more stable and effective UV filters that last longer on the skin and offer protection from a wider range of light, including blue light and infrared radiation.
Higher-quality sunscreens can also include beneficial ingredients like antioxidants, which fight free radicals and environmental damage, and hydrating components that moisturize the skin instead of drying it out. They are also more likely to be formulated for sensitive skin, are less likely to clog your pores, and are often free from irritating perfumes and alcohol.
