What is ectoine?

Ectoine is a naturally occurring molecule produced by microorganisms living in extreme environments such as saltwater lakes, deserts, and polar regions. These so-called extremophiles have adapted to these hostile conditions, and ectoine plays a crucial role in this adaptation. It protects the cells of these microorganisms from heat, dryness, UV radiation, and osmotic stress.


Ectoin is a versatile active ingredient with a wide range of applications. It is a safe and effective way to care for the skin and improve its health.

Effects of ectoine

Ectoin has a wide range of effects: it is antioxidant, anti-inflammatory, and moisturizing. It repairs the skin barrier and protects against environmentally induced skin aging. Ectoin can bind water molecules and form hydrocomplexes. These complexes envelop cells, proteins, and enzymes with a protective layer of moisture.


Ectoin protects your skin from external stressors and allergens. It protects Langerhans cells, the immune cells of the epidermis, from UV damage. It also improves the tolerability of active ingredients such as retinol, vitamin C, niacinamide, azelaic acid, and peels. At a 1% concentration, ectoin can be as effective as cortisone creams, but its moisturizing properties eliminate the drying side effects of cortisone.


Very high concentrations of 5-7% help with eczema and atopic dermatitis. Ectoin protects against particulate matter as well as PAHs (polycyclic aromatic hydrocarbons) and heavy metals. Ectoin has been proven to protect the skin from blue and visible light and pigmentation caused by UV radiation.

  • Moisturizing: Ectoin binds water in the skin, keeping it hydrated. This can relieve dryness, itching, and redness.
  • Anti-inflammatory: Ectoin inhibits inflammation in the skin. This can help relieve the symptoms of conditions such as atopic dermatitis.
  • Antioxidant: Ectoin protects the skin from damage caused by free radicals. Free radicals are molecules that can cause cell damage and premature aging.
  • Soothing: Ectoin soothes irritated skin and relieves itching and burning.
  • Protects against UV radiation: Ectoin can protect the skin from the harmful effects of UV radiation.
  • Strengthens the skin barrier: Ectoin strengthens the skin barrier, which protects the skin from harmful environmental influences.

Origin of Ectoin

salt lake

Ectoin can protect microorganisms that live in extreme conditions, such as salt lakes, hot springs, arctic ice, the deep sea, or the desert.


It was discovered in 1985 in a microorganism living in a salt lake in the Egyptian desert. This extremely protective effect makes it very interesting for skincare, especially for very damaged, sensitive skin.
