Summary

This serum contains beneficial ingredients such as niacinamide, glycerin, and tocopherol, which are known for their skin-soothing, moisturizing, and antioxidant properties. However, the presence of dimethicone, a synthetic silicone, and the processed nature of the product slightly reduce its overall score. Despite these factors, the serum's formulation is largely composed of safe and effective ingredients, contributing to its favorable rating.
