Our body and skin are constantly exposed to stressors in the environment - pollution, UV radiation, chemical exposure and extreme weather conditions. Our skin, being the first line of defense, does what it can to protect us but using skincare that supports and protects the natural function of the skin is very important - especially for sensitive skin.

Every now and then, science discovers something so beneficial for skin that it grabs the attention of the beauty industry. Ectoin is one of those ingredients because its superpower is like a “force-field” around cells to protect and defend against the damaging effects of the environment we live in.

What Is Ectoin? Big Skin Benefits From Microscopic Life

Ectoin was discovered in 1986 by German scientists. It is a molecule produced by microorganisms called extremolytes that live in the most severe and hostile environments.

Originally discovered in the Egyptian desert, Ectoin has the ability to protect cells from oxidative stress when exposed to stressors like UV radiation, dryness and inflammation. Found in polar ice, hot geysers, volcanic terrain, and arid wastelands, extremolytes thrive because Ectoin creates a water layer that shields and protects them. Many tests have been done over the years that have proven Ectoin’s ability to protect DNA, human cells and tissue.

3 Primary Ectoin Benefits For Skin

The large-scale production of Ectoin is done through a fermentation process that is sustainable and reduces water consumption and energy. Used in the medical and cosmetic field, Ectoin is an amazing ingredient to look for in your daily skincare.

1. Ectoin Increases Skin Hydration and Supports Skin Barrier Function

The primary job of skin is to act as the boundary between you and the outside world.  To do that job skin uses lipids, hardened skin cells, protective peptides and more.  When your skin barrier is functioning well you're able to retain moisture in skin and repel irritants that contact skin from the outside.

Many people cope with skin barrier problems, though, and chronic skin conditions like rosacea, acne, eczema, and psoriasis are examples of situations where the skin barrier can be degraded due to factors like inflammation and improper formation of skin cells and lipids.  This can result in redness, dryness, and further inflammation to the skin.  

Even just washing your hands frequently can cause skin barrier disruption and subsequent dryness.  The right skincare with the right ingredients can help fortify the skin barrier and reduce discomfort and symptoms of chronic skin conditions.

Ectoin, an amino acid derivative, has been proven to improve skin barrier function for those struggling with extreme sensitivities from atopic dermatitis. It creates a water seal around proteins, known as the Ectoin hydro-complex, which prevents transdermal water loss and improves hydration in the skin. 

Water is attracted and bound to the Ectoin molecule. As the Ectoin molecule surrounds cells, enzymes, and proteins it creates a protective shell of water around them that behaves differently than if the Ectoin was not there.  This cushion also increases the hydration levels for cells, cushions them from the impacts of stress, and increases cellular membrane fluidity. 

Improved hydration supports a healthy barrier function resulting in the skin's ability to protect itself against inflammation caused by things like chemical irritation and allergens.

2. Ectoin Protects Skin from UV Damage

UV radiation is responsible for much of the premature aging we experience as humans. UVB rays are responsible for sunburn and inflammation in the epidermis, the outer layer of the skin. UVA penetrates much deeper to the lower dermis and is responsible for the degradation of collagen and elastin which results in advanced signs of aging like wrinkles and loss of elasticity.

Ectoin has the ability to protect against the oxidative stress and inflammation in skin caused by UVA  radiation. There is also evidence that Ectoin reduces the stress on the cellular activity from UVB exposure.

In addition, Ectoin has shown to have antioxidant capabilities that neutralize free radical activity. Ectoin is a truly holistic helper to supporting the skin’s natural ability to defend itself from the aging effects of UV radiation.

3. Ectoin Stops Skin Inflammation

We hear a lot about the importance of Sun protection but do we consider the damage from chemical overload and pollution in our environment as much? For those who are prone to sensitivities or suffer from more severe issues like eczema, rosacea and acne, it just makes sense to have ingredients like Ectoin defending your vulnerable skin.

Ectoin has been widely studied for its ability to reduce inflammation and protect cells for many conditions including respiratory and eye health. Many of these studies include skin cells and have shown that Ectoin can protect skin cells from pollution and prevent the inflammation that happens when the skin is triggered.

Ectoin does not interact directly with your cells.  It just changes how the water in your tissues behaves. 

This property is one reason it is such an excellent ally to highly reactive skin.  The Ecoin does not communicate with your cells or cause reactions on its own, it simply cushions them from stress and allows them to function in a better-resourced, more resilient way.

How to use Ectoin in Skincare

Now that you know why Ectoin is such a fantastic discovery for sensitive skin you may want to start using it!  The good news is that Ectoin is easy to incorporate into your skincare routine.

Who will benefit most from using Ectoin?

Anyone of any age can use Ectoin and experience improvements to skin hydration, increased resilience, and support with the effects of UV light.Ectoin is safe and beneficial to use on children, adults, during pregnancy and breastfeeding, and on aging skin.

Is Ectoin safe to use with chronic skin conditions like eczema, rosacea, psoriasis, and acne?

Yes, Ectoin is safe to use with chronic inflammatory skin conditions.  Most of these skin conditions involve damage to the skin barrier function, which Ectoin can help repair.  

Ectoin has been specifically studied for use with skin with atopic dermatitis (eczema) with soothing results that may allow people to reduce the use of corticosteroids.

Ectoin is water based and noncomedogenic and has been used on skin with acne in studies with good results.

Is Ectoin pregnancy safe?

Yes, Ectoin is generally considered pregnancy safe and at this time there are no known risks from using it during pregnancy or breastfeeding.

What concentration of Ectoin is needed in skincare to see benefits?

Ectoin may be used at concentrations of .3% to 7%.  Benefits for skin can be seen at any of these concentrations.  Ectoin manufacturers often recommend the .3% to 2% use level for typical skincare products.

• Typical skincare may contain .3% to 1% Ectoin for general soothing and hydration.
• Anti-aging benefits and intensive care products may contain 1% to 2% Ectoin.
• Clinically therapeutic treatment for skin disorders like eczema may encompass levels of 5.5%-7% Ectoin.

A study examining the use of Ectoin skincare on acne utilized a level of 1% and saw good improvements to acne levels and skin hydration for study participants.

Does Ectoin interact with or degrade other ingredients in skincare products?

Generally Ectoin does not interact with or degrade other ingredients in skin care recipes.  It’s unusual for an active ingredient to be so flexible in formulations.  Ectoin plays well with many other actives in your skin care products.  Ectoin is a water soluble ingredient, so you will find it in products that have at least some water content.

Can you use Ectoin with retinol?

Yes, you can use Ectoin with actives like retinols or Vitamin C products.  Your skin can actually benefit from combining Ectoin with actives like this that cause exfoliation of the skin barrier.  The hydrating properties of Ectoin will help reduce irritation from aggressive treatments like this.

Research has shown that Ectoin can help reduce irritation from isotretinoin use and makes a fine complement to help people stick to their treatment regimen.

How long does Ectoin stay good in skincare?

Ectoin is also a very stable molecule and does not degrade with exposure to heat.  This plus its nonreactivity with other skincare ingredients means it stays active for years in your skincare products.

While Vitamin C and other actives may degrade over time Ectoin will still be giving you a substantial benefit long into the future.

What skincare products are the best ones to contain Ectoin?

You’ll get the most benefit from Ectoin if you use it in a product that will remain on the skin.  That means toners, serums, moisturizers, and sunscreens are some top types of product where you’ll see the most results. 

The data shows that “ectoin functions as a superior moisturizer with long-term efficacy”. Afterall, Ectoin is a natural function of microorganisms living in the most inhospitable environments to protect themselves. Knowing that it shares its superpower on human skin cells, makes it a game-changer for your skin care routine everyday.

It is so mild, safe, and beneficial that Ectoin even appears in products like eye drops and nasal sprays.

Ectoin In Sunscreen: Heroic Skin Protection

Sun exposure can be a substantial and direct cause of skin irritation.  Along with long term UV damage to skin there can be temporary inflammation, free radical formation, and dryness caused by time catching some rays.

The way that Ectoin reduces stress from UV exposure and helps skin cope with inflammation makes it an ideal holistic skin helper in sunscreens. 

Chemical UV filter actives in sunscreens are notoriously reactive as well, and can degrade easily if not properly formulated.  Ectoin’s stability as a molecule makes it uniquely capable of adding skin benefits to your sunscreen without compromising the efficacy of UV filters.  Whether you use Ectoin in your skincare prior to sunscreen or use a sunscreen with Ectoin you can expect good results.

Currently only a handful of sunscreens feature Ectoin.  It’s likely to appear in premium sunscreens for sensitive skin since it is a somewhat costly ingredient to use in skincare.  

Many sunscreen products are only formulated to be a barrier and do not support the skin from a nutritional perspective, so shop carefully for sunscreen with Ectoin that will soothe sensitive skin.

Are the additional ingredients in your sunscreen supporting your skin’s health? Or are they contributing to irritation and triggering your already vulnerable skin?
