A: It is NOT "right on the bottle." That's their made up "hydration complex"--which is a meaningless phrase. All hyaluronic acid offered OTC is usually between 1% - 2 %. I went with Loreal at 1.5%.

A: It says right on the bottle in the picture for the product - 17%.

A: Thanks for your question! This is considered proprietary information so we cannot release the percentage for this product. Thanks and we hope you understand!

A: Great question, Jules! Yes, the Neutrogena Hydro Boost Hyaluronic Acid Serum with Vitamin B5 can be used around the eyes to help with dry skin. It's formulated with hyaluronic acid, a powerful humectant that attracts and retains moisture.

A: Hi there! Our Neutrogena Hydro Boost Hyaluronic Acid Serum with Vitamin B5 for Dry Skin comes in a recyclable glass bottle. This packaging choice aligns with Neutrogena's commitment to sustainability and provides a premium feel to the product.

A: Hi, we do not have information about this product having low molecular weigh

A: Hi there, this product does not contain sunscreen.

A: Hey Carla, that's a really great question! There are some formulation differences between these two products. For example, the Hydrating Serum uses dimethicone, dimethiconol, ethylhexylglycerin, and bisabolol as skin conditioners while the Hyaluronic Acid Serum doesn't have any of those ingredients! The main difference you may notice, would be things like the consistency of the product and the method of application.
