Olay Regenerist Deep Hydration Regenerating Cream is an anti-aging face cream that is said to keep your skin moisturized and immediately soften the look of fine lines and wrinkles. One of the key ingredients in this cream is niacinamide, a form of vitamin B3 that plays a vital role in cellular metabolism. This means that niacinamide provides skin cells with the energy needed to perform important processes, such as DNA repair and cell turnover. Niacinamide also has the ability to repair the skin barrier and improve skin moisture, as well as reduce inflammation, blotchiness, hyperpigmentation, acne, and wrinkling. Another key ingredient is palmitoyl pentapeptide-4, a type of messenger peptide that provides anti-aging benefits by signaling to cells to produce more collagen. Ultimately, this helps to reduce the appearance of fine lines and wrinkles. There are two very effective humectants in the Olay Regenerist Deep Hydration Regenerating Cream: glycerin and panthenol (provitamin B5). A humectant is a hygroscopic substance that has a molecular structure with several hydrophilic (water loving) groups. This structure allows humectants to attract moisture and draw that moisture into the upper layers of skin, thereby improving hydration. Another key ingredient in the Olay Regenerist Deep Hydration Regenerating Cream is allantoin, which is a very gentle and effective moisturizing ingredient. Additionally, allantoin is a keratolytic, which means it has the ability to smooth skin through exfoliation of the top layer of dead skin cells. Allantoin can help to increase skin smoothness, aid in wound healing, and promote cell proliferation and longevity. Lastly, Olay Regenerist Deep Hydration Regenerating Cream provides your skin with protection against free radicals due to the antioxidants in green tea leaf extract and the lipid soluble antioxidant vitamin E.
