Lovi Assistant explains
- Offers moderate hydration benefits for your dry skin, as ectoin and hyaluronic acid provide humectant action to enhance barrier resilience and general hydration. Glycerin further supports this by attracting moisture to the skin.
- This formula is highly suitable for dry skin due to the humectant properties of glycerin and hyaluronic acid, which are present in concentrations that provide adequate hydration.
- The safety profile is excellent, with no risks of irritation for your dry skin due to the absence of prohibited or harsh ingredients.
How to apply
- Could be used as part of your AM or PM routine. Start using it 3 times a week and work your way up to daily use.
- Apply your moisturizer after your toner and before your sunscreen in the morning. At night, use it as the final step after your serum.
- Gently press a small amount of the moisturizer into your skin. Avoid rubbing to keep your dry skin happy.
- Apply the moisturizer on slightly damp skin to help lock in extra hydration. This is great for soothing dry and flaky areas .
- Avoid the sensitive eye area and do a patch test before your first use .

Questions and answers
How well does THE INKEY LIST Ectoin Hydro-Barrier Serum work for dry skin?
This serum works moderately well for dry skin, as ingredients like ectoin, hyaluronic acid, and glycerin pull in moisture and help protect your skin barrier without causing irritation. Products that fit dry skin even better need a richer blend of deep moisturizers, multiple types of hyaluronic acid, and barrier-repairing ingredients like ceramides or nourishing extracts to lock in lasting hydration.
Which ingredients make this serum a good fit for dry skin?
Ectoin, hyaluronic acid, and glycerin make this serum a good fit for dry skin by drawing in moisture and helping strengthen the skin barrier. Because it lacks harsh ingredients, it is unlikely to cause irritation. To fit dry skin even better, this type of product needs extra nourishing extracts, ceramides, and multiple types of hyaluronic acid to maximize moisture retention.
What does Ectoin do for dry skin?
Ectoin helps dry skin by locking in moisture to keep it soft and smooth while strengthening the outer barrier to stop water from escaping. It may also calm redness and ease skin sensitivity.
Clinics in Dermatology, 2008European Journal of Dermatology, 2025
What does Hyaluronic Acid do for dry skin?
Hyaluronic acid draws moisture into dry skin, giving an immediate and lasting boost in hydration that helps smooth out fine lines and soften rough patches. It is very gentle and unlikely to cause irritation while improving overall skin smoothness and plumpness.
Dermatology and Therapy, 2021Journal of Drugs in Dermatology, 2011
Where does this serum go in a skincare routine for dry skin?
This serum goes in the evening routine after cleansing and before moisturizing, though some serums can also be used in the morning or twice a day. Dry skin needs a moisturizing treatment with hydrating ingredients like hyaluronic acid and glycerin to draw in moisture and keep the skin soft and smooth.
The Journal of Dermatological Treatment, 2022Clinical, Cosmetic and Investigational Dermatology, 2017
Can I use this serum with retinol, and in what order?
You can use this treatment in your evening routine before your moisturizer and after your cleanser, and it may help support your skin while you use retinol. A product of this type for dry skin needs rich moisturizers or plant oils to lock in hydration and prevent dryness.
How often should I use this serum?
You can use this treatment in the evening as part of your routine, as ectoin, hyaluronic acid, and glycerin help draw in moisture and keep your dry skin comfortable. This serum is unlikely to cause irritation due to its gentle ingredients, though a product of this type for dry skin generally needs richer oils and butters to fully lock in hydration.
Journal of Cosmetic Dermatology, 2020Health Science Reports, 2021
Can this serum clog pores, cause breakouts or purging for dry skin?
This serum is unlikely to cause breakouts or reactions for your dry skin, as it has an excellent safety profile without harsh ingredients. However, because it offers only moderate hydration, dry skin typically needs a rich cream with heavy oils or butter to lock in moisture and fully prevent tightness.
Can I use this serum around the eyes or on my body?
You can safely use this moisturizing treatment around the eyes and on the body because it has a very safe formula with no harsh ingredients. To properly care for dry skin in those areas, a product of this type needs rich ingredients like ceramides, squalane, and rich plant oils to lock in deep moisture and protect the skin barrier.
Is this serum fragrance-free and alcohol-free?
Yes, it has no fragrance and no drying alcohol.
What the research says
A single application of a moisturizing fluid containing hyaluronic acid 1%, glycerin 5%, and Centella asiatica stem cells extract significantly increased skin hydration by 29% and reduced transepidermal water loss at 24 hours compared to baseline and an untreated control site in twenty healthy women.
Clinical, Cosmetic and Investigational Dermatology, 2017Combining ectoine and mannitol with UV filters significantly improved protection of squalene oxidation, catalase activity, and trans-UCA compared to UV filters alone in 10 subjects on irradiated areas.
Journal of Cosmetic Dermatology, 2024Topical 7% ectoine during serial 1064-nm Nd:YAG laser therapy produced a greater reduction in skin erythema, improved stratum corneum hydration, reduced transepidermal water loss, and decreased low-echogenic pixels in thirty participants compared to a vehicle control.
Biomedicines, 2026Regular application of a novel anti-ageing cream containing hyaluronic acid, ectoin, and botanical actives significantly reduced wrinkle depth and length in the periorbital area while demonstrating very good skin tolerance.
Polymers, 2023Topical application of 0.1% hyaluronic acid formulations of different molecular weights led to significant improvements in skin hydration and elasticity, with low-molecular-weight formulations also significantly reducing wrinkle depth in seventy-six female subjects compared to a vehicle control.

BMC Oral Health, 2019The emollient V0034CR significantly reduced TEWL compared to vehicle and vehicle plus glycerol, and significantly increased corneometry scores compared to vehicle and vehicle plus petrolatum in healthy volunteers with dry skin, demonstrating combined barrier function improvement from petrolatum and hydration improvement from glycerol.
Journal of Cosmetic Dermatology, 2020Ten days of treatment with a cream containing 20% glycerin significantly increased skin hydration measured by corneometer values in 17 healthy volunteers compared to a placebo cream, but showed no influence on transepidermal water loss or skin sensitivity to an irritating surfactant.
