The efficacy score of 4.4/5 reflects strong moisturizer fundamentals: glycerin and propanediol provide high-position humectancy, squalane and multiple lipids provide emollience, and five ceramides plus hydrogenated lecithin support barrier function. The amino-acid/PCA blend adds sensible water-binding support, while the peptide complex is a reasonable bonus but should not be treated as the primary driver of results. The near-neutral manufacturer-reported pH of approximately 6 is appropriate for a moisturizer. The score is held below the top range because the formula does not disclose concentrations, the peptides are lower in the list, and Isopropyl Myristate plus Ethylhexyl Palmitate may be problematic for users prone to comedones.
