- The formula is highly suitable for normal skin due to the humectant action of glycerin and hyaluronic acid.
- The safety profile is excellent, with no risks of irritation for your normal skin due to the absence of prohibited or harsh ingredients.

## 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/))
- Topical hyaluronic acid filler serum combined with Botulinum toxin type A lengthened the duration of the toxin's effect in reducing wrinkles compared to Botulinum toxin type A alone. ([Dermatologic Therapy, 2022](https://pubmed.ncbi.nlm.nih.gov/36200921/))
- 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.

- Apply this product after your toner and serum, but before your SPF in the morning. Follow your cleanser and toner steps to keep your skin balanced.
- Gently press a small amount into your face and neck. Avoid rubbing the skin too harshly to prevent extra tension.

## Questions and answers

### How well does The Inkey List Ectoin Hydro-Barrier Serum work for mature skin?

This serum works moderately well for mature skin, offering basic hydration that helps support fine lines. However, mature skin needs products with powerful anti-wrinkle and nourishing ingredients that deeply enhance skin vitality and radiance.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/), [Dermatologic Therapy, 2022](https://pubmed.ncbi.nlm.nih.gov/36200921/)

### Which ingredients make this serum a good fit for mature skin?

Ectoin, hyaluronic acid, and glycerin make this serum a good fit by hydrating and supporting your skin. Hyaluronic acid further helps address wrinkles and fine lines. A product for mature skin also needs effective anti-wrinkle ingredients, nourishing agents, and skin-repairing components to enhance vitality and radiance.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/), [Dermatologic Therapy, 2022](https://pubmed.ncbi.nlm.nih.gov/36200921/)

### What does Ectoin do for mature skin?

For mature skin, ectoin helps keep skin hydrated and smooth while supporting firmness and protecting against everyday damage. It helps improve moisture levels and preserves collagen, which is especially beneficial since mature skin tends to become dry and lose its bounce.
Sources: [International Journal of Cosmetic Science, 2026](https://pubmed.ncbi.nlm.nih.gov/41116229/)

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

Hyaluronic acid helps mature skin by deeply boosting moisture, improving elasticity, and smoothing the appearance of fine lines and wrinkles. Regular use keeps the skin looking plump and soft while supporting overall firmness and hydration.
Sources: [Journal of Drugs in Dermatology, 2011](https://pubmed.ncbi.nlm.nih.gov/22052267/), [Skin Research and Technology, 2024](https://pubmed.ncbi.nlm.nih.gov/38591218/)

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

This serum goes in the evening routine after cleansing and before moisturizing, which keeps the routine simple and safe around sun exposure. Mature skin needs products with nourishing hydrators and firming ingredients like peptides and antioxidants to smooth fine lines and support elasticity.

### 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 comfortable and hydrated. This type of routine benefits from barrier-protecting ingredients like ceramides and nourishing oils to further support mature skin.
Sources: [Cutis, 2006](https://pubmed.ncbi.nlm.nih.gov/17121065/)

### How often should I use this serum?

You can use this serum in your evening routine as a treatment step, applying it daily after cleansing and before moisturizing. To better care for mature skin, this type of product also needs richer anti-aging ingredients and deep moisturizers that smooth wrinkles and keep dry skin soft.
Sources: [Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/32141711/), [Health Science Reports, 2021](https://pubmed.ncbi.nlm.nih.gov/34141902/)

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

This serum is unlikely to cause breakouts or clogged pores for mature skin because its safety profile is excellent and it lacks harsh or irritating ingredients. Mature skin needing better anti-aging results typically benefits from ingredients that boost firmness, smoothness, and deep hydration.

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

Yes, you can use this serum on the thin skin around your eyes and on your body because its safety profile is excellent with no harsh ingredients. However, mature skin needs stronger anti-wrinkle ingredients and richer moisture to truly smooth out fine lines and soften dry 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.
