From Beautypedia.com: This is a silky, water-based serum that contains a fairly broad complement of beneficial ingredients for all skin types. It contains approximately 2% to 3% niacinamide, and, in this amount, it can increase the skin's ceramide and fatty acid content as well as have anti-inflammatory action and work to reduce hyperpigmentation (Sources: The New Ideal in Skin Health: Separating Fact From Fiction, Thornfeldt Carl MD, Allured Books, 2010, pages 160-161; and Journal of Cosmetic Dermatology, April 2004, pages 88–93).
Olay claims the peptide this contains can regenerate and intensely hydrate skin. Peptides are cell-communicating ingredients that can help improve skin's appearance and enhance its healthy functioning, but they are not miracle-workers for skin, nor are they all that hydrating on their own. They're good ingredients to see in anti-aging products, but they're not must-haves, so don't get too caught up in the peptide hype.
The various types of silicones that really give this product its elegant texture and make skin feel unbelievably silky, while the aluminum starch lends a powder-like finish best for normal to oily skin. This serum runs circles around most products sold as foundation primers, so be sure to consider this if you're of the mindset that a primer is essential to seamless makeup application. You can use a serum like this instead and save yourself an extra step!
This serum penetrates into skin's surface to deliver our super-concentrated amino-peptide + B3 complex. This fast absorbing, non-greasy formula provides specially designed hydration to give you significantly firmer skin and regenerate skin's appearance.
