So why the seemingly sudden proliferation of ectoin and what is it?
Meet the experts:
What is ectoin?
Belovedpeptides, for example, are short chains of amino acids.
Ectoin, discovered in 1985, falls into this category.
In this case, its actually a very good thing.
Specifically, says board-certified dermatologistShereene Idriss, MD, Its an extremolyte, which is extracted from extremophilic microorganisms.
Extremolytes help protect cellular integrity in extreme weather conditions.
Ectoin is a relatively small molecule that readily binds to water molecules to create complexes, Koestline says.
What are ectoins skin-care benefits?
Ectoin is a multitasker.
It doesnt just do it all it does it allwell.
But it does have certain talents that are particularly impressive.
Ectoin’s superstar ability is protection, says Dr. Idriss.

Board-certified dermatologistMarissa Garshick, MD, concurs.
Ectoin works to provide a protective shield for the skin, she says.
By protecting against external stressors, it also offers protection against blue light and pollution.
But it isnt just your box screen against which ectoin defends skin.
That doesnt mean its a stand-in for sunscreen, though.
(Currently, the FDA recognizes only 16mineral and chemical filtersas active sunscreen ingredients.)
Basically, it offers nearly everything many of us are looking for in a skin-care ingredient.
It is a natural moisture binder, says Dr. Geria.
Its great for smoothing rough and scaly skin and can reduce inflammation.
It also works for lines and wrinkles [by providing] long-term hydration.
As we said, it does it all.
What are the best ways to work ectoin into your skin-care routine?
At the same time, it also helps to minimize the unwanted side effects of other, harsher ingredients.
