Ectoin Is the Little-Known Skincare Ingredient that’s About to Be Everywhere

As beauty editors, we remember every time we’ve ever introduced a new hero ingredient into our skincare routines (it’s not crazy if it’s part of our job, right?). For example, we remember the first time we discovered the hydrating and plumping powers of hyaluronic acid. We also remember discovering the smoothing effects of retinol and the pore-minimizing powers of niacinamide. The list goes on. The point is that all of these hero ingredients played a role in changing our skin for the better, and now there’s another one to incorporate.  We’re talking about ectoin. If you’ve never heard of it, you’re not alone. While it’s lesser-known than other skincare ingredients, it’s basically a multi-tasking miracle, tackling a number of skin concerns all at once. Keep scrolling to learn everything there is to know about ectoin, according to expert dermatologists. Plus, see a selection of the best ectoin skincare products to shop. 

According to double-board-certified dermatologist, Brendan Camp, MD, “Ectoin is an organic compound found within bacteria that acts as an osmolyte, meaning that it helps cells maintain an appropriate fluid balance.” Translation? It acts as a moisturizer and emollient, hydrating and softening the skin. 

Don’t be fooled, though. Ectoin offers many more benefits than just smoother, more moisturized skin. Take it from board-certified dermatologist, Geeta Yadav, MD. “Emollients work by helping skin retain moisture, but 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.” 

So, yeah, ectoin targets everything from dryness to inflammation, dullness, and pigmentation. Talk about a multi-tasking ingredient. That explains why some people have deemed it the “new” niacinamide. “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, though it is an interesting comparison,” Yadav says. “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 skin care ingredients that help protect and maintain skin health.” 

Because ectoin offers multiple benefits, 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 over-exfoliated with retinoids. It’d also be a good pick for use in winter time, when the skin barrier may be imbalanced due to harsh weather conditions.” 

Yadav recommends this sunscreen, which is a “Shimmery, fun sunscreen that contains ectoin as well as antioxidants, green tea and ginger root, and gentle skin resurfacers, papaya and pineapple.”

“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,” Yadav says.

Camp recommends this skin barrier-strengthening cream from Dr. Jart. “This hydrating cream moisturizer contains ceramides to repair and maintain the integrity of the skin barrier and ectoin to restore dry skin,” he says.

“This daily SPF 30 facial moisturizer protects skin from ultraviolet radiation and contains ectoin, among other ingredients, to keep skin hydrated,” Camp says. 

Acne-prone skin types will love this mineral sunscreen, which offers SPF 30. It’s airy, lightweight, and it won’t worsen clogged pores or cause extra breakouts. 

“This hydrating serum contains hyaluronic acid composed of different molecular weights to improve skin penetration and ectoin to balanceskin hydration,” Camp says. 

Along with ectoin, this moisturizer-sunscreen hybrid contains vitamin C to shield skin from damaging UV rays and environmental aggressors. 

Ectoin, squalane, and vitamin C make this moisturizer perfect for anyone who’s struggling with dullness, dryness, or uneven texture. 

This toner soaks the skin in hydration thanks to ingredients like ectoin, glycerin, and sodium hyaluronate. Consider it to be a tall glass of water for your skin.
