Daily skin stress doesn’t come from the sun alone. Pollution, heat and dehydration also put pressure on the skin every day. Within Likami SHIELD, one ingredient plays a key role in this daily defence: ectoin.

What is ectoin and what does it do for your skin?

Ectoin is a biomimetic protective molecule that was originally discovered in micro-organisms that survive in extreme conditions, such as heat, salt and intense UV exposure.

On the skin, ectoin forms a protective micro-environment around skin cells. This makes them more resistant to daily external stress, without sealing off the skin. Ectoin supports the skin from within and helps it remain resilient.

Ectoin is known as an ingredient that is particularly well tolerated. It is often used for sensitive, dehydrated or easily reactive skin, because it helps protect the skin without irritating or weighing it down. This makes ectoin particularly suitable for daily use, even when the skin feels out of balance.

You can think of ectoin as an ingredient that helps the skin stay calm, hydrated and in balance — even when it is exposed daily to sun, pollution and temperature changes.

Not protecting by sealing the skin off, but by supporting it.

Why is ectoin used in Likami SHIELD?

Within Likami SHIELD, ectoin is not used as a standalone ingredient, but as the core of the Ectoin Shield Complex®. This complex forms the bio-intelligent foundation of all SHIELD Daily Defence Fluids.

What ectoin does specifically:

It stabilises cell membranes, helping the skin stay balanced
It reduces oxidative stress, a key contributor to premature skin ageing
It helps limit moisture loss, keeping the skin comfortable and supple
It calms micro-irritation, even in sensitive or reactive skin types

This makes ectoin particularly suitable for daily use, all year round.

Protection that goes beyond SPF

Sun protection is essential, but true daily skin protection goes further than UV alone. That’s why SHIELD combines 100% mineral filters with the Ectoin Shield Complex®.

The mineral filters protect the skin against UVA, UVB and blue light, while ectoin helps the skin to:

cope better with heat and pollution
lose less moisture
respond more calmly to external triggers

Together, they form a coherent protection system that doesn’t overload the skin, but supports it — day after day.

One protective core, three skin-intelligent variants

The Ectoin Shield Complex® is present in all three SHIELD Daily Defence Fluids. The protective base remains the same, while the action is refined according to specific skin needs.

Hydrate + Barrier
Supports moisture retention and helps strengthen the skin barrier when experiencing dryness or a tight feeling.

Calm + Soothe
Helps the skin settle during redness, sensitivity and stress-related reactions.

Correct + Brighten
Protects against oxidative triggers that can intensify an uneven skin tone and pigmentation.

In this way, every skin receives tailored daily protection - without compromising on comfort.
