Efficacy-wise, it combines proven UVB filters (homosalate, octisalate) and a UVA filter (avobenzone) with emollient solvents and film-formers for spread and adherence, plus humectants and niacinamide for light brightening and barrier support, but it lacks newer, more photostable filters or iron oxides that would push it into a top-tier protection class, and the niacinamide and birch sap sit in a mostly moisturizing-supporting role rather than functioning as a high-dose treatment centerpiece.
