How has sunscreen changed over the years?

Sunscreen has evolved significantly over the years, transitioning from basic formulations with low SPF to advanced products featuring higher SPF ratings and broad-spectrum protection against both UVA and UVB rays. Innovations have led to the incorporation of physical and chemical filters, making sunscreens more effective and cosmetically appealing, with lighter textures and water-resistant properties. Additionally, there has been a growing emphasis on skin health, leading to the inclusion of antioxidants and moisturizing ingredients. Environmental concerns have also spurred the development of reef-safe formulas, reducing harmful chemicals that can affect marine life.
