CINCINNATI — New research has found that two Olay body moisturizing formulas with niacinamide provide rapid, lasting dry skin benefits over conventional moisturizers.
Procter & Gamble said Thursday that the Journal of Drugs in Dermatology recently published the results of two randomized, controlled studies evaluating the skin barrier integrity and skin hydration benefits of various moisturizers containing differing levels of oils/lipids (such as petrolatum and mineral oil), humectants (such as glycerin) and other ingredients (including niacinamide).
The studies found the two body moisturizers containing a niacinamide/glycerin formula, Olay Advanced Healing Lotion and Olay Ultra Moisture Lotion, had significant advantages versus a number of competitive moisturizers in two key areas: improving skin barrier over time and rapidly hydrating skin, according to P&G.
The two niacinamide/glycerin moisturizers demonstrated an overall better solution for rapid and prolonged improvement of dry skin because of their functional improvement of skin barrier function compared with no treatment and the other moisturizers tested, P&G said. Based on that research, Olay Quench Advanced Healing Lotion is clinically proven to hydrate better than one of the moisturizing products from a leading dermatologist recommended brand, the company stated.
"Because cosmetic skin dryness continues to be a leading skin problem for consumers, we wanted our research to focus on an ingredient formulation that would provide significant benefit to skin moisturization and barrier integrity," explained Rolanda Johnson, a senior scientist at P&G Beauty & Grooming and co-author of the study. "When formulated in combination with humectants, such as glycerin, a well-known water-soluble, hydroscopic lipid, the niacinamide-containing moisturizers tested in these studies, Olay Advanced Healing Lotion and Olay Ultra Moisture Lotion, break the dry skin cycle and help heal the moisture barrier."
When tested against one of the moisturizing products from a leading dermatologist recommended brand, Olay Advanced Healing Lotion was clinically proven to provide better moisturization, P&G reported.
"These findings demonstrate that cosmetic moisturizers formulated with niacinamide go beyond moisturization to improve the integrity of the stratum corneum [skin barrier] for improved skin benefits over time," according to Johnson. "Furthermore, the speed benefit seen with the niacinamide/glycerin formulas in both studies can be attributed to niacinamide, as it has been shown to be a cosmetic ingredient with multiple benefits on aging skin appearance. The sustained improvements in skin integrity after the final treatment also demonstrated niacinamide’s ability to work within the skin’s surface, even if the product is not being used."
