This Skincare Ingredient Is the Anti-Inflammatory Gold Standard, But You've Probably Never Heard of It
I've been a beauty editor for nearly a decade, which means I've seen the rise and fall of hundreds of trends, including those that involve specific skincare ingredients. For instance, I remember when the beauty industry went wild for the hydrating benefits of hyaluronic acid. (It's strange to think about a time when it wasn't pervasive in thousands of skincare products. These days, it's a part of our core skincare vernacular.) I also remember the rise of retinol and the internet's initial obsession with niacinamide. Well, now, there's another ingredient to incorporate: ectoin.
If you've never heard of ectoin, you're not alone. It doesn't get nearly as much hype or attention as other ingredients, but that's changing fast. Top skincare brands like Rhode, The Ordinary, Eadem, and more are launching new products that tout ectoin as a hero ingredient. And for good reason. It's highly effective and targets multiple skin concerns at once. Dermatologists even say it's an anti-inflammatory gold standard. Ahead, learn everything you need to know about ectoin, straight from the experts. Plus, see a selection of the best ectoin products to incorporate into your routine. Trust me, after this, you'll want to.
What Is Ectoin, and How Does It Benefit the Skin?
Brendan Camp, MD, FAAD, is a double-board-certified dermatologist at MDCS Dermatology. He says ectoin is an organic compound found in bacteria. "It acts as an osmolyte, meaning that it helps cells maintain an appropriate fluid balance." So, essentially, ectoin is an efficient emollient, which means it moisturizes, hydrates, and softens the skin on contact.
That's its most basic benefit. Ectoin offers many others. Take it from board-certified dermatologist and founder of Facet Dermatology, Geeta Yadav, MD, FRCPC. "Ectoin also offers protective and anti-inflammatory properties as well as skin-brightening benefits. A recent study of the ingredient in children and adults with inflammatory skin conditions showed that ectoin positively influences change in skin dryness, is safe and well-tolerated, and can support the health and repair of the skin barrier. Another study shows that it activates antioxidant pathways while inhibiting tyrosinase, the enzyme responsible for skin cell pigmentation."
Yep, ectoin is A) moisturizing, B) anti-inflammatory, and C) brightening. Talk about a multitasking ingredient. For this reason, some people online have deemed it the "new" niacinamide. (For context, niacinamide is known for a similarly wide range of benefits, including hydrating, anti-aging, and pore-minimizing ones.)
When I ask the experts about this comparison, they say there is indeed some truth to it. "I think that's just a way of saying that it's an ingredient people should know about, or it's about to become very trendy," Yadav says. "Though it is an interesting comparison. Not everyone can tolerate niacinamide well, especially in high concentrations, and ectoin can be comfortably used by those with impaired skin barriers."
Camp agrees. "Niacinamide is a different derivative of vitamin B, so it has a different molecular structure than ectoin. Niacinamide and ectoin work differently but are often compared because they are buzzy skincare ingredients that help protect and maintain skin health," he says.
What Skin Types Does It Benefit?
Ectoin offers multiple benefits, which means it's well-suited for multiple skin types. "Ectoin can be used on most skin types, though it may be most beneficial on dry, rough skin because it is an effective emollient, which means it helps skin feel soft and smooth," Camp says.
Yadav seconds that, saying it can benefit multiple skin types, but it may be best for those who need moisture and anti-inflammatory effects. "It's best suited for skin that needs help retaining moisture, but it's well documented as being a safe ingredient, so a variety of skin types could use it," she says. "Because of the clinical study I mentioned earlier, this is a great ingredient for those with inflammatory skin conditions, like eczema, to rely on, as well as those who have overexfoliated with retinoids. It'd also be a good pick for use in the wintertime when the skin barrier may be imbalanced due to harsh weather conditions."
The Best Ectoin Skincare Products
This face mist is formulated with ectoin, panthenol, cica, polyglutamic acid, glycerin, and aloe. As such, it soothes, hydrates, and supports the skin barrier. It whipped my sensitive skin back into shape when I started using retinol again after a six-month break.
This serum is the epitome of ultra-hydrating. With 2% ectoin, 2.5% multi-molecular hyaluronic acid, and a 1% "Barrier Blend," it quite literally transformed my dull, dry skin into soft, smooth, and plump skin.
I love affordable skincare products, but only if they're effective, like The Ordinary's Rice Lipids + Ectoin Microemulsion Moisturizer. It's basically a liquid moisturizer that soothes, moisturizes, and reduces redness in a snap.
If you find most gel cleansers strip your skin and leave it dry and irritated, this is your fix. The pH-balanced formula contains ectoin and ceramides to keep moisture intact, while gentle surfactants remove sunscreen, makeup, oil, and pollution.
Exfoliating pads are another infamously irritating product category, but YSE Beauty's Your Favorite Ex Exfoliating Pads are different. They contain ectoin to maintain moisture and soothe sensitivity, so the glycolic acid can slough away dead skin without irritation.
I reach for Rhode's Glazing Mist almost daily. The combination of ectoin, ceramides, and magnolia extract keep my skin calm, hydrated, and super glowy.
Yadav recommends this sunscreen, which is a "shimmery, fun sunscreen that contains ectoin as well as antioxidants, green tea, and gingerroot and gentle skin resurfacers papaya and pineapple."
Yadav also recommends this firming and plumping serum. "This serum features the brand's signature skin moisturizer, squalane, as well as ectoin to help strengthen the skin barrier and a blend of firming peptides."
Meanwhile, this is one of Camp's top picks. "This hydrating cream moisturizer contains ceramides to repair and maintain the integrity of the skin barrier and ectoin to restore dry skin," he says. I can attest to its efficacy. It's a good option for anyone who struggles with dry, irritation-prone skin (especially in cold weather!).
Here's another product Camp recommends (and I second). "This daily SPF 30 facial moisturizer protects skin from ultraviolet radiation and contains ectoin, among other ingredients, to keep skin hydrated," he says. In my experience, this moisturizer keeps my skin soft, smooth, and plump, even though I'm prone to dryness and irritation. And I'll never say no to extra sun protection.
While hyaluronic acid receives top billing in this serum, Camp says it also contains ectoin, which explains why it's so superbly hydrating. "This hydrating serum contains hyaluronic acid composed of different molecular weights to improve skin penetration and ectoin to balance skin hydration," he says.
Ectoin, squalane, and vitamin C are the triple threat behind this moisturizer. It's ideal for mature skin or anyone who struggles with dullness, dryness, or texture.
If you want to drench your skin in moisture, I recommend this ectoin-infused essence. The hero ingredient, along with the help of glycerin and sodium hyaluronate, provides lightweight hydration. It's like a drink of water for my skin.
If you want to bring the benefits of ectoin to your bodycare routine, I highly recommend Cyklar's Body Oils. They make my skin feel petal-soft, and they smell incredible. The last time I used this body oil, I had a literal stranger come up to me and ask what perfume I was wearing. Enough said.
