Skin-care ingredients tend to trend in a big way until something ostensibly newer comes along and bumps it out of the spotlight, even if it\u2019s not actually inherently better. As of late, comparisons between the beloved niacinamide and the new-to-consumers ectoin have begun to rack up. We asked experts to explain the difference and confirm or deny once and for all if one is superior.<\/p>\n

What is ectoin?<\/h2>\n

\u201cEctoin is a relatively small cyclic amino acid that readily binds to water molecules to create complexes. Extremophile microorganisms (microbes that love extreme conditions) that live in extreme salinity, pH, drought, temperature and irradiation produce these amino acids to protect their cells against chemical and physical damage,\u201d explains clean cosmetic chemist and founder of KKT Consultants Krupa Koestline. \u201cThe ectoin-based complexes provide proactive, nourishing and stabilizing hydration shells that surround cells, enzymes, proteins and other biomolecules, thereby reducing oxidative stress and upregulation of cell inflammation,” she says. These are all good things when it comes to our skin.<\/p>\n

The benefits of ectoin<\/h2>\n

Koestline says since its discovery in 1985, ectoin has been studied for its hydrating and anti-inflammatory properties. \u201cIt\u2019s been shown to increase the intrinsic water content of the skin. It\u2019s also been demonstrated to work against wrinkles and enhance skin elasticity and smoothness by improving skin barrier function, and reducing transepidermal water loss, explains Koestline.<\/p>\n

Cosmetic chemist Gloria Lu says ectoin has a reputation for being effective and multi-functional, which we love to see in skin care. It seems ectoin has many potential uses. Cosmetic chemist Ginger King says, \u201cIt’s great for stressed skin and skin barrier protection as well as hydration.\u201d Lu says it\u2019s also been looked at as an ingredient that may help soothe atopic dermatitis.<\/p>\n

Why is ectoin being compared to niacinamide? Is one better than the other?<\/h2>\n

While the two ingredients work differently, they\u2019re both multifunctional active ingredients, explains King. Furthermore, the ingredients do share some similar benefits, \u201clike reducing transepidermal water loss, anti-inflammatory properties and antioxidant benefits. Both can also be formulated into lightweight serums, which is likely why people compare the two ingredients,\u201d explains Koestline.<\/p>\n

There haven\u2019t been any one-on-one comparison studies, so it can\u2019t be determined if ectoin or niacinamide is superior, says Koestline. It\u2019s best to appreciate both for their many strengths. \u201cNiacinamide has more testing in terms of topical skin-care benefits, targeting anything from pores to hyperpigmentation,\u201d says Lu. \u201cOn the other hand, ectoin is positioned more as a hydrating ingredient that can protect skin from UV-induced damage.\u201d<\/p>\n

Why is ectoin suddenly in the spotlight?<\/h2>\n

Cosmetic chemist Victoria Fu chalks it up, in part, to the nature of the beauty industry. \u201cEctoin has been looked at for potential skin benefits as early as the 2000s. Since there’s been renewed interest in more gentle, skin-barrier friendly skin care, ectoin is on the radar again,\u201d she says.<\/p>\n

Koestline agrees the spiked interest has something to do with the current trend in restoring the skin barrier. Barrier-restoring products are generally lightweight, nourishing, and anti-inflammatory, and ectoin falls in that category. \u201cIt also works well when paired with active ingredients like AHAs, BHAs, retinoids, etc. that may cause inflammation and redness to help mitigate any potential side effects,\u201d she adds. Additionally, there is also a drive in the industry “toward using biotech ingredients that are sourced sustainably through fermentation, which ectoin falls under.\u201d<\/p>\n

Can you use ectoin and niacinamide together?<\/h2>\n

Absolutely, in fact, New York dermatologist Dr. Shereen Teymour says they complement each other very well. \u201cNiacinamide helps support barrier function, regulate oil production and reduce inflammation, while ectoin helps protect the skin from environmental stress and water loss.\u201d Together, both ingredients are great for those dealing with sensitivity, dehydration, redness or an impaired skin barrier.<\/p>\n

According to New York dermatologist Morgan Rabach, MD, when formulated together, ectoin and niacinamide help the skin better tolerate actives such as acids and retinol. Mirroring that sentiment, Dr. Teymour adds that ectoin may even help improve the tolerability of higher niacinamide concentrations in those with sensitive skin.<\/p>\n

Who should use ectoin vs. niacinamide?<\/h2>\n

Of the two ingredients, ectoin is generally well tolerated by most people and is one of those rare skin-care ingredients that works for almost anyone. It is especially beneficial for those who have dry, reactive or sensitive skin. \u201cI also like it for patients who overdo active ingredients, travel frequently, live in urban environments or undergo cosmetic procedures because it helps support the skin barrier and reduce inflammation,\u201d says Dr. Teymour. Ectoin also offers extra barrier support for those who use exfoliating acids, acne treatments and retinoids.<\/p>\n

The only caveat, Dr. Teymour points out, is that you should not assume that because the ingredient itself is gentle that every product containing it will automatically be non-irritating; it\u2019s still important to consider other ingredients in product formulations. Typically, she says, most skin-care products contain 0.5 to two percent of ectoin and don\u2019t pose a risk of irritation at high concentrations.<\/p>\n

Niacinamide, on the other hand, should be applied with caution. Though a versatile ingredient\u2014it can help regulate oil production, improve barrier function and reduce redness and pigment, at high percentages\u2014it can still cause some dryness or irritation, says New York dermatologist Dr. Kiran Mian. \u201cI frequently recommend it for patients with acne-prone skin, rosacea-prone skin, post-inflammatory hyperpigmentation or compromised skin barriers,\u201d says Dr. Teymour.<\/p>\n

To combat any negative effects from niacinamide, it is recommended to use a lower percentage. In many cases, lower concentrations (between two and five percent) of the ingredient are not only better tolerated but are equally as effective. \u201cMore is not always better when it comes to skin-care ingredients, especially in patients with reactive skin,\u201d says Dr. Teymour.<\/p>\n
