System Verdict
Solid humectant serum with smart multi-weight PGA and osmolytes, but lacks clinical concentration proof and penetration enhancers for elite efficacy. Efficacy score of 4.0 reflects strong 1% pure PGA + 3% complex (optimal ~3-5% range per studies) with dual weights for surface/film hydration and antioxidant benefits, 10% glycerin for barrier support, and synergistic ectoin/osmolytes for water balance; minor deduction for no encapsulation or pH optimizers specified and potential humectant overload in low-HA environments without occlusion.
