Algae Is Now in Your Skin-Care Products...for Some Reason

How much can kelp really help?

skin care , and a bunch of other industries as a thickening agent. But now, certain types of algae—like spirulina—are being treated like trendy ingredients that can supposedly bring big benefits (including the possibility of an algae-derived sunscreen!). But before we let ourselves get too excited, we spoke to a few experts to figure out if the science actually backs up these claims. So, what kind of algae are we talking about, exactly? Algae, which can be big like sea kelp or tiny enough to be microscopic, are chlorophyll-containing organisms found in the ocean. But it’s estimated that there are over 70,000 species of algae out there—and that’s not including the many “extracts” that may be called algae on the front of a skin-care bottle. So, uh, we might need to get a little more specific. “It’s a really huge category that we’re talking about and it’s hard to narrow down what [skin-care companies] are trying to aim for,” Evan Rieder, M.D., assistant professor in the Ronald O. Perelman department of dermatology at NYU Langone Health, tells SELF. That’s why the skin-care industry has so far focused its efforts on a few of the most common types of algae. And, in practice, only a few algae species have actually been studied for possible use in cosmetic products anyway. That includes the three major classes of macroalgae (a.k.a. seaweed), which are brown (sea kelp), green, and red. It also includes different types of microalgae, such as spirulina, a type of blue-green algae, and chlorella, a green algae. Each of these has its own set of skin-care claims to go with it, including everything from possible antioxidant benefits, to moisturizing and anti-aging powers, all the way to UV protection. “It’s one of the hottest ingredients out there right now,” Binh Ngo, M.D., clinical associate professor of dermatology (clinician educator), Keck School of Medicine of USC, tells SELF. “There’s a lot of claims out there that it can do this and do that, but you have to look at the evidence.” Is there any evidence that these can be beneficial for skin? Although there are some studies looking at the possible skin benefits of algae in humans, the research we have is generally limited to laboratory and animal studies, Dr. Rieder says. But there are some interesting things to uncover. For instance, in published in 2013 in the International Journal of Biological Macromolecules, researchers looked at the potential for compounds extracted from five different types of algae to absorb and retain moisture, something that could obviously be useful in skin care . They examined how much water the algae—which included three different types of green algae, one type of red algae, and one type of brown algae—would absorb when dry and how well it would then retain it over time. Their results showed that the brown algae extract, which had the lowest molecular weight, did the best. In fact, the results were even better than hyaluronic acid , a common skin-care ingredient that’s known for its powerful humectant effect. However, this study was done in the lab—not on actual human skin. So, we don’t know if these extracts would do the same thing for your face. Next up is spirulina, a species of blue-green algae (which is technically a type of cyanobacteria and, therefore, not a true Read more: SELF
