The formulation
Ingredient stack
Each ingredient is listed in descending concentration. Above the 1% line the order is regulated — below it, brands can list in any order.
Ingredients above the dashed gold line are dosed above 1% (the regulatory threshold) — these are what the formulation is really built on.
The single most evidence-backed anti-aging intervention. UV drives 80–90% of visible skin aging, hyperpigmentation and skin cancer risk. SPF 30 blocks ~97% UVB; SPF 50 blocks ~98%. Mineral filters (zinc oxide, titanium dioxide) physically deflect UV; chemical filters absorb and convert UV to heat.
The closest active-matched alternative is the Round Lab Birch Juice Moisturizing Sunscreen SPF 50+ (99% active overlap). We found 1 option that share this product’s hero actives.
