## 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, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/))
- Combining 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, 2024](https://pubmed.ncbi.nlm.nih.gov/37539499/))
- Topical 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, 2026](https://pubmed.ncbi.nlm.nih.gov/42792808/))
- Regular 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, 2023](https://pubmed.ncbi.nlm.nih.gov/37896378/))
- Topical 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. ([Journal of Drugs in Dermatology, 2011](https://pubmed.ncbi.nlm.nih.gov/22052267/))
- Topical application of hyaluronic acid in conjunction with free gingival graft significantly reduced donor site postoperative pain until day 7 compared to normal saline, with no significant differences in graft dimensions or patient satisfaction. ([Clinical Oral Investigations, 2022](https://pubmed.ncbi.nlm.nih.gov/34623507/))
- Treatment with a hyaluronic acid-containing mouth rinse or topical gel led to significant lesion reduction, pain relief, and normalization of lesion color in adult patients with minor recurrent aphthous stomatitis, with the gel formulation showing an earlier healing onset at 3 days. ([BMC Oral Health, 2019](https://pubmed.ncbi.nlm.nih.gov/31311529/))
- The 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, 2020](https://pubmed.ncbi.nlm.nih.gov/31532576/))
- Ten 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. ([International Journal of Cosmetic Science, 2001](https://pubmed.ncbi.nlm.nih.gov/18498456/))
- Niacinamide/glycerin body moisturizers provided better rapid and prolonged improvement of cosmetic xerosis through functional improvement of stratum corneum barrier function compared to no treatment and conventional moisturizers in female subjects. ([Journal of Drugs in Dermatology, 2012](https://pubmed.ncbi.nlm.nih.gov/22206073/))

## Questions and answers

### Why is THE INKEY LIST Ectoin Hydro-Barrier Serum a weak match for combination skin?

This serum is a weak match because it only provides basic hydration, whereas combination skin needs products with ceramides, peptides, or niacinamide and beneficial extracts to manage oily shine and keep the complexion balanced.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

### Which ingredients make this serum a poor fit for combination skin?

This serum is a weak match because it only provides basic hydration, lacking the advanced oil control, ceramides, niacinamide, or peptides needed to properly balance combination skin. A product of this type needs richer hydrating and skin-repairing ingredients to manage oily shine and maintain a radiant complexion without excess oil.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

### What does Ectoin do for combination skin?

Ectoin helps keep combination skin balanced by holding onto moisture and strengthening the skin barrier without feeling heavy. It is unlikely to irritate dry or oily patches and may help calm redness while protecting skin cells from everyday damage.
Sources: [Clinics in Dermatology, 2008](https://pubmed.ncbi.nlm.nih.gov/18691511/), [Arhiv Za Higijenu Rada I Toksikologiju, 2016](https://pubmed.ncbi.nlm.nih.gov/28033102/)

### What does Hyaluronic Acid do for combination skin?

Hyaluronic acid is a great fit for combination skin because it quenches dry areas with a boost of hydration while keeping oily zones balanced. Regular use helps smooth out fine lines and makes your skin feel soft and plump without causing irritation.
Sources: [Dermatology and Therapy, 2021](https://pubmed.ncbi.nlm.nih.gov/34176098/), [Journal of Drugs in Dermatology, 2011](https://pubmed.ncbi.nlm.nih.gov/22052267/)

### Where does this serum go in a skincare routine for combination skin?

This serum goes in the evening routine after cleansing and toning, and before moisturizing. Combination skin needs targeted ingredients like niacinamide or lightweight hydrators that balance oily shine while maintaining moisture without feeling heavy.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

### Can I use this serum with retinol, and in what order?

You can use this serum with retinol by applying it before your retinol to help keep your skin calm and hydrated. Combination skin needs a lightweight, balancing moisturizer with ceramides and niacinamide to keep the skin barrier strong and manage oily shine without heavy layers.
Sources: [Cutis, 2006](https://pubmed.ncbi.nlm.nih.gov/17121065/)

### How often should I use this serum?

You can use this serum daily in your evening routine, applying it after cleansing and before moisturizing. While it is generally safe for combination skin, a product of this type needs richer or more targeted balancing ingredients to provide a strong fit for your skin.
Sources: [Health Science Reports, 2021](https://pubmed.ncbi.nlm.nih.gov/34141902/)

### Can this serum clog pores, cause breakouts or purging for combination skin?

This serum is unlikely to cause breakouts for combination skin, as it contains no harsh or prohibited ingredients that trigger irritation. A product of this type needs lightweight hydrators like glycerin and hyaluronic acid, along with barrier-supporting ingredients such as ectoin, to keep combination skin balanced without clogging pores.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

### Can I use this serum around the eyes or on my body?

You can use this serum around the eyes and on your body, as its gentle hydrating formula is well tolerated by delicate skin areas. This product provides basic moisture, but your combination skin needs stronger barrier repair ingredients and targeted nourishment to truly thrive in those areas.
Sources: [Surgical and Radiologic Anatomy, 2002](https://pubmed.ncbi.nlm.nih.gov/12375070/), [Polymers, 2023](https://pubmed.ncbi.nlm.nih.gov/37896378/)

### Is this serum fragrance-free and alcohol-free?

Yes, it has no fragrance and no drying alcohol.
