Ingredients and how they matter
- Aqua (water) serves as the base for the serum, providing a lightweight medium for hydration delivery.
- Glycerin acts as a humectant, attracting water to the skin to help maintain moisture levels for a hydrated appearance.
- Sodium Hyaluronate and Hydrolyzed Hyaluronic Acid are forms of hyaluronic acid that bind water, providing immediate plumping and long-lasting hydration.
- Panthenol (provitamin B5) supports moisture retention and may contribute to skin softness and comfort.
- Madecassoside is a plant-derived compound known for soothing properties and support of the skin’s renewal processes.
- Tocopherol (vitamin E) provides antioxidant support to help protect skin from free radicals and support overall skin health.
- Phenoxyethanol and Parfum provide preservation and fragrance in mild formulations; those with sensitive skin may want to patch test first.
