The science behind the pursuit of youthful skin is ever-evolving. Americans have come to rely on the skin care industry having a new breakthrough around every corner.
Truth be told, new scientific discoveries that will ultimately change the way skin ages—or doesn’t—do not happen every day. Then, even when an exciting ingredient appears on the stage, it takes at least a few large-scale double-blind studies to prove the hypothesis of what benefit it might provide to human skin. There are ingredients, some long-standing and some new, that having proven their efficacy or have sparked interest in further study. Learning to rely on science and not marketing is the best way for skin care professionals and clients alike to identify truly effective skin care ingredients.
New isn’t always better
Sometimes the best new ingredients are actually long-standing proven ingredients that have benefited from new science. Many new ingredients have yet to have the scientific studies performed on them to substantiate their purported claims. For proven ingredients, even decades of positive study outcomes and visible results are not indicative of an inability to improve formulations. Two excellent examples of this are vitamins A and C. Certainly neither of these topical antioxidants is new to skin care, but both can provide even better outcomes on skin as a result of improved stabilization technology. Retinol (vitamin A) and L-ascorbic acid (vitamin C) are inherently unstable when formulated into topical products. Utilizing new technology can allow these two integral ingredients to provide even more dramatic benefits to skin health.
