When skin is stressed or the barrier is compromised, it struggles to hold water – showing up as tightness, roughness, reactivity, dullness (even actives can feel harsher). Most hydrators sit on the surface – 7% ectoin (known as “the stress-protection molecule”), seven weights of hyaluronic acid & water-binding glycogen come together to support vital substances skin needs for optimum hydration, so moisture seeps deeper and lasts longer. This milky, lightweight serum delivers instant relief & visibly repairs the barrier in 7 days. Skin bounces back faster, with dryness, roughness and irritation visibly improved.

How to use a serum
Apply once or twice daily after cleansing, toning and exfoliating. Follow with a serum and/or moisturiser. For daytime, always use with a moisturiser containing a broad-spectrum SPF 30 or higher.
The 7% Ectoin + Hyaluronic Acid Milky Hydrating Serum is perfect for anyone dealing with dry or dehydrated skin. It’s also ideal for barrier impairments or skin conditions marked by dryness, rough texture or sensitivity.
Yes, the formula is suitable for all skin types. Its ability to attract and retain moisture (combined with its skin barrier-protecting properties) does make it a standout choice for those with dehydrated, dry or sensitive skin.
This serum features a high 7% concentration of ectoin (which is much more than typical formulas) making it especially effective for dry, dehydrated or stressed skin. It also includes seven weights of hyaluronic acid (sodium hyaluronate) for deep, multi-layer hydration, as wel as glycogen to help replenish ceramides and strengthen the skin barrier.
The 7% Ectoin + Hyaluronic Acid Milky Hydrating Serum is a specialised 7-in-1 treatment featuring 7% ectoin and higher amounts of hyaluronic acid (sodium hyaluronate) at various molecular weights. This targeted formula is ideal for dry, dehydrated skin and barrier impairments, while other Paula’s Choice moisturisers address a broader range of needs, including signs of ageing. Unlike our oil-in-water moisturisers, the Ectoin Serum is a water-in-oil emulsion, providing enhanced moisturisation. This unique emulsion type (though harder to stabilise) is better suited for dry, dehydrated skin due to its oil-soluble ingredients and water-soluble ectoin.
Yes, ectoin’s gentle touch calms and soothes sensitive, redness-prone skin while delivering deep hydration and increased barrier strength. If facial redness is among your primary concerns, the products in our CALM collection are your best match and you can layer them with this 7% Ectoin Serum. Even better? Ectoin forms what’s known as “hydration shells” around skin cells, protecting them from external triggers of redness. It can also instantly hydrate to comfort skin and diminish the appearance of flushing associated with sensitive skin.
Yes, in fact, ectoin can help reduce the redness and discomfort acne can cause. Its humectant properties can help offset dryness and scaling that can occur from use of potent or prescription retinoid treatments. The hyaluronic acid/glycogen blend also works to prevent dehydration without adding a slick, greasy texture. This is a water-in-oil emulsion so it’s not considered oil free.
Yes, the ingredients in the 7% Ectoin + Hyaluronic Acid Milky Hydrating Serum are considered safe to use during pregnancy or while breastfeeding. If you’re uncertain about starting a new product or a new combination of ingredients while pregnant or breastfeeding, check with GP and follow their advice.
While our formulas steer clear of irritating ingredients, each product may have a unique scent due to its ingredients. The scent of the Ectoin Serum that some may notice is from the combination of ingredients it contains. This scent dissipates quickly after application.
Yes, this serum is vegan, silicone free and paraben free. It is a water-in-oil emulsion so it’s not considered oil free.
There aren’t any specific skincare ingredients known to be incompatible with ectoin. Ectoin can be layered with many other beneficial ingredients such as vitamin C, retinoids, peptides, niacinamide and more.
Both boosters help repair a compromised barrier, but in different ways: hyaluronic acid attracts and holds moisture, while ectoin helps retain it by forming a protective hydration shell around cells. Ectoin also stabilises proteins and lipids in the skin barrier, preventing water loss and supporting even moisture distribution. Also, our Hyaluronic Acid Booster has a semi-viscous gel texture, while the 7% Ectoin Serum features a milky, emollient texture. The Hyaluronic Acid Booster hydrates and plumps skin with hyaluronic acid and ceramides to support the skin’s natural moisture barrier. In contrast, the 7% Ectoin Serum is ideal for dry, dehydrated or sensitive skin (including eczema-prone types) offering a more comprehensive solution to restore comfort and smoothness.
