System Verdict
This is an impressively modern, high-coverage chemical sunscreen with genuinely barrier-friendly support, but the beta-glucan and peptide story is mostly marketing gloss given their ultra-low (ppm‑level) concentration. The SPF system uses a sophisticated mix of newer filters (Uvinul T 150, Uvinul A Plus, Mexoryl XL, Ecamsule, and Diethylhexyl Butamido Triazone) in the top of the INCI, which justifies a high efficacy score for UV protection and photostability, while a silicone–fatty alcohol–polymer base should give a comfortable, non-greasy finish. However, beta-glucan is declared at 1,000 ppb (~0.0001%), far below levels used in soothing/hydration studies, and the peptide and ginseng extract sit near the bottom of the list, so they add negligible treatment benefit beyond marketing; the real non-UV benefits come from humectants (2,3-butanediol, glycols) and mild soothing agents like panthenol and allantoin in mid-to-low positions. The absence of fragrance and denatured alcohol and the use of fatty alcohols rather than harsh surfactants support a strong safety score for most skin types, with irritation risk mainly limited to those sensitive to chemical filters.
