System Verdict

Solid drugstore sunscreen with broad-spectrum coverage, but photostability and UVA protection are compromised by weak filter synergy and avobenzone instability. The formula contains four UV filters (Octocrylene 10%, Homosalate 7.3%, Octisalate 5%, Avobenzone 3%), which theoretically provides broad-spectrum SPF 50 coverage. However, efficacy is undermined by critical formulation flaws: (1) Homosalate is notoriously photounstable, losing 10% SPF in just 45 minutes—it should not be a primary filter in a stick sunscreen meant for extended outdoor use. (2) Avobenzone (3%) is present but lacks sufficient photostabilizers; Octocrylene provides some stabilization, but the concentration is marginal for reliable UVA I protection. (3) The stick format, while convenient, concentrates these filters in a lipophilic base that may not spread evenly, risking uneven UV coverage. (4) Positive notes: Octisalate enhances water resistance, and the formula includes antioxidants (Tocopherol, Oryzanol, Watermelon Extract) and soothing agents (Bisabolol) that add minor skin-benefit value. The emollient base (Sunflower Oil, Mineral Oil, Silicones) is non-comedogenic and skin-friendly. For a stick sunscreen at this price point, the UVB coverage is adequate, but the UVA protection is borderline and reapplication every 45–60 minutes is essential due to Homosalate degradation.
