Susanne Kaufmann Ectoin Repair Serum

A clinically tested ectoin serum designed to reinforce the skin barrier, replenish hydration, and visibly calm redness and signs of environmental stress.

Susanne Kaufmann Ectoin Repair Serum is a next-generation barrier-support serum created for skin affected by dehydration, sensitivity, urban pollution, temperature fluctuations, and environmental exposure.

At the heart of the formula is sustainably cultivated ectoin, a protective molecule produced through biotechnology in Germany. Known as an extremolyte for its ability to help microorganisms survive hostile environments, ectoin helps stabilise the skin barrier, reduce transepidermal water loss, and support the skin’s ability to adapt to external stress.

Coenzyme Q10 provides antioxidant protection, while purple algae extract helps reduce visible redness and unevenness. A botanical complex of hollyhock, black currant bud, edelweiss, Alpine rose, and gentian supports a calmer, healthier-looking complexion.

Silky, featherlight, and fast-absorbing, the serum layers effortlessly beneath moisturiser and sunscreen, leaving stressed skin feeling hydrated, balanced, and more resilient.

Benefits:

• Clinically tested to support skin-barrier repair and protection
• Helps reduce transepidermal water loss
• Delivers lasting, lightweight hydration
• Clinically tested to reduce the appearance of redness
• Helps soothe visible irritation and sensitivity
• Supports a balanced skin microbiome
• Defends against environmental oxidative stress
• Helps improve the appearance of fine lines, fatigue, and uneven tone
• Leaves skin feeling calmer, more comfortable, and resilient
• Suitable for all skin types, including sensitive skin

Recommended For:

• Dehydrated or moisture-depleted skin
• A weakened or compromised skin barrier
• Visible redness and sensitivity
• Skin stressed by travel or changing climates
• Exposure to pollution, heat, cold, and environmental stress
• Dry, mature, normal, combination, or oily skin
• Dullness, fine lines, and signs of fatigue
• Anyone seeking lightweight barrier support beneath moisturiser

The formula contains alcohol, fragrance, and camphor. Highly reactive, fragrance-sensitive, or freshly treated skin should patch test first and follow the advice of its skincare professional.

Why It’s Different:

Ectoin is a naturally occurring protective molecule used by extremophile microorganisms to survive environments marked by intense heat, dryness, salinity, and UV exposure.

When used in skincare, ectoin helps stabilise cell membranes, preserve moisture, and support the skin barrier against environmental stress. It does not simply add temporary surface hydration—it helps create the conditions needed for the skin to retain water and function more effectively.

The formula pairs ectoin with liposomal coenzyme Q10, purple algae extract, and Alpine botanicals to address several signs of stressed skin simultaneously: dehydration, visible redness, sensitivity, dullness, and reduced resilience.

This serum does not replace sunscreen. Although ectoin helps defend the skin against UV-induced oxidative stress, it does not provide an SPF.

Clinically Tested Results:

After 28 days, the formula was clinically shown to:

• Support repair and protection of the skin barrier
• Reduce the appearance of redness
• Soothe visible irritation
• Improve skin comfort

In a separate 28-day clinical study, the purple algae active reduced visible skin redness by 19%.

In a 28-day user trial:

• 93% said their skin looked healthier
• 93% said their skin felt more comfortable
• 92% said their skin felt calmer
• 91% said their skin looked regenerated
• 91% said their skin felt soothed

Product clinical-study results are based on 20 participants after 28 days. Purple algae active results are based on 14 participants after 28 days. User-perception results are based on 108 participants after 28 days. Individual results may vary.

Texture & Aroma:

A silky, featherlight serum that absorbs quickly and layers easily beneath moisturiser, facial oil, makeup, and sunscreen.

The formula contains fragrance and camphor and is not fragrance-free. Slight separation may occur when the bottle is left standing for an extended period; this is normal and does not affect performance.

How to Use:

1. Cleanse the face and leave the skin slightly damp.
2. Apply two or three drops to the face, neck, and décolleté.
3. Gently press the serum into the skin until absorbed.
4. Follow with moisturiser or facial oil.
5. Use morning and evening.
6. Apply broad-spectrum sunscreen as the final step of the morning routine.

If the serum separates, ensure the bottle is securely closed and shake gently before application.

Loshen & Crem’s Recommendation:

Think of this serum as daily resilience support rather than something reserved only for a skin emergency. It is especially useful during seasonal transitions, after travel, or whenever the complexion feels dehydrated, easily flushed, or less tolerant than usual.

For a complete barrier-support routine, begin with Susanne Kaufmann Soothing Cleansing Milk, follow with the Ectoin Repair Serum, and seal in hydration with the moisturiser best suited to your skin.

During the day, complete the routine with Ectoin Barrier Repair Moisturiser SPF 50 for broad-spectrum protection.

After professional treatments, introduce the serum only once your facialist or treatment provider confirms that fragranced skincare, alcohol, and camphor are appropriate for your recovery stage.

Frequently Asked Questions:

What does Susanne Kaufmann Ectoin Repair Serum do?
It helps reinforce the skin barrier, improve moisture retention, calm visible redness, and protect the complexion from environmental oxidative stress.

What is ectoin?
Ectoin is a naturally occurring protective molecule produced by microorganisms that survive extreme environments. In skincare, it helps stabilise the skin barrier, retain moisture, and support resilience against external stress.

Is Ectoin Repair Serum clinically tested?
Yes. After 28 days, the serum was clinically shown to support barrier repair and protection while reducing visible redness and soothing irritation. The product study involved 20 participants.

How quickly will I see results?
The skin may feel more hydrated and comfortable after application. The brand’s clinical and consumer trials evaluated results after 28 days of consistent use.

Is it suitable for sensitive or reactive skin?
The brand recommends it for sensitive and reactive skin. However, the formula contains alcohol, fragrance, and camphor, so highly reactive or fragrance-sensitive skin should patch test before use.

Can I use it when my skin barrier is damaged?
It is designed to support a stressed or weakened barrier. If the skin is severely inflamed, broken, burning, or reacting to everything, simplify the routine and consult a qualified skincare or healthcare professional before introducing new products.

Can I use it after microneedling, laser, or chemical peels?
Do not assume that it is suitable immediately after a professional procedure. Because it contains alcohol, fragrance, camphor, and mild acids, use it only when your treatment provider confirms that your skin is ready.

Does it help with redness or rosacea?
The serum is clinically tested to reduce the appearance of redness, but it is not a treatment for rosacea or another medical condition. Rosacea-prone skin should patch test and introduce it gradually.

Can I combine it with retinol or exfoliating acids?
Yes, ectoin can complement active routines by supporting hydration and barrier resilience. If your skin is irritated, temporarily reduce strong actives rather than expecting the serum to offset over-exfoliation.

Can I use it with vitamin C or niacinamide?
Yes. It can be layered with vitamin C, niacinamide, hyaluronic acid, peptides, ceramides, and antioxidant serums.

When should I apply it in my routine?
Apply after cleansing and toner, before moisturiser, facial oil, and sunscreen.

Should it be applied to damp skin?
Yes. Applying two or three drops to slightly damp skin helps the serum spread evenly and supports hydration.

Does it replace sunscreen?
No. Ectoin can help protect against UV-induced oxidative stress, but it does not provide SPF. Always apply a broad-spectrum sunscreen during the day.

Why has my serum separated?
Natural separation may occur when the serum stands for an extended period. Secure the top and shake gently before applying. This does not affect performance.

Is it fragrance-free?
No. The formula contains parfum and camphor.
