Summary
This serum contains beneficial ingredients like mandelic acid, glycerin, and sodium hyaluronate crosspolymer, which are known for their exfoliating and hydrating properties. However, the presence of polysorbate 20, a synthetic emulsifier, and the processed nature of the product slightly reduce its overall score. The formulation is generally safe and effective, but the inclusion of some synthetic components prevents it from achieving a top-tier rating.
