Dermatologists and sun protection experts are advocating for consistent, year-round use of sunscreen to mitigate skin damage. Experts note that while UVB rays fluctuate seasonally, UVA rays remain relatively constant and can penetrate clouds and glass, contributing to wrinkles, pigmentation, and skin cancer risk. Recent data indicates that 60% of solar radiation is received outside of the summer months. Professionals highlight the importance of protecting children during school and outdoor activities, noting that many adults neglect photoprotection due to the misconception that tanning indicates good health. Advancements in the consumer sector include products designed to protect against UVA, UVB, visible light, and infrared rays. To maintain skin health during seasonal transitions, experts recommend broad-spectrum sunscreen with SPF 30 or higher, even as temperatures drop. For effective application, a specific layering principle is advised: cleansing, toner, water-based serums, functional skincare, moisturizer, sunscreen, primer, foundation, and powder. While moisturizer can be omitted if the sunscreen is sufficiently hydrating, experts warn it should “never be mixed directly into the sunscreen,” as this dilutes protective efficacy. Users may layer different sunscreens or combine mineral and chemical formulas—ideally applying the lighter texture first—though SPF values do not add up mathematically. Additionally, makeup containing SPF should be treated as a supplement rather than a primary defense, as typical application amounts of SPF-infused cosmetics are often insufficient to meet labeled protection levels.
