System Verdict
This is a very solid, high-coverage barrier-supporting sunscreen, but the blueberry and peptides are marketing fluff compared to the heavy chemical filter load and potential Benzophenone-3 issues. The formula earns a good efficacy score because it uses a modern multi-filter system (including S Tier filters like Terephthalylidene Dicamphor Sulfonic Acid and Ethylhexyl Triazone) plus ceramides, phospholipids, cholesterol and humectants to genuinely support barrier repair and hydration, yet some older filters (Benzophenone-3 in earlier lists) and antioxidant/berry claims are likely present at low, non-core concentrations, so they do not justify an S Tier rating for treatment benefits.
