Works for oily acne-prone skin; other moisturizers fit it better.

## Why this fit

- Offers moderate hydration for your oily skin, as glycerin and ectoin provide humectant benefits and enhance barrier resilience without adding excess oil.
- While beneficial for general hydration, the formula lacks specialized ingredients to directly target your concerns of acne, blemishes, and breakouts.
- The product is safe for your oily skin, featuring soothing ingredients like ectoin and hyaluronic acid with no risk of irritation.

## 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/))

## Why other moisturizers fit oily acne-prone skin better

- Gluconolactone 14% solution significantly improved mild to moderate acne by reducing inflamed and non-inflamed lesions similarly to 5% benzoyl peroxide, but with fewer side-effects in 150 patients. ([The Australasian Journal of Dermatology, 1992](https://pubmed.ncbi.nlm.nih.gov/1303072/))
- A peel-off facial mask containing myoinositol and trehalose-loaded liposomes improved adult female acne by decreasing lesion counts, sebum production, GAGS scores, and local androgen levels while increasing beclin-1 levels. ([Journal of Cosmetic Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28342238/))
- Co-delivery of paeonol and madecassoside via nanoemulsions improved transdermal delivery, promoted barrier repair proteins, inhibited inflammatory cytokine secretion in cellular and 3D models, and reduced transepidermal water loss and acne in human facial skin compared to free components. ([Molecules, 2023](https://pubmed.ncbi.nlm.nih.gov/37446936/))

## Questions and answers

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

THE INKEY LIST ECTOIN HYDRO-BARRIER SERUM works moderately well for your oily acne-prone skin, as glycerin and ectoin provide moisture without adding excess oil, but it lacks ingredients to directly target breakouts. Products that fit this skin better need ingredients like niacinamide, ceramides, and targeted blemish fighters that balance oil and hydrate without clogging pores.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

### Which ingredients make this serum a good fit for oily acne-prone skin?

Glycerin, ectoin, and hyaluronic acid make this serum a fit by offering moderate hydration and strengthening your skin barrier without adding excess oil. To best care for oily acne-prone skin, this type of product also needs ingredients like niacinamide, ceramides, or targeted blemish-fighters that clear pores and balance oil while keeping skin calm.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

### What does Ectoin do for oily acne-prone skin?

Ectoin helps protect oily acne-prone skin from sun damage and premature aging caused by UV rays. It is lightweight and unlikely to clog pores, making it a comfortable addition to your daily routine.
Sources: [Journal of Cosmetic Dermatology, 2024](https://pubmed.ncbi.nlm.nih.gov/37539499/), [Skin Pharmacology and Physiology, 2004](https://pubmed.ncbi.nlm.nih.gov/15452409/)

### What does Hyaluronic Acid do for oily acne-prone skin?

Hyaluronic acid helps calm oily acne-prone skin by reducing sebum production and lipid synthesis in sebaceous glands. It also supports skin barrier function and improves hydration while helping deliver treatments without causing irritation.
Sources: [The Journal of Investigative Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28163068/), [Journal of Cosmetic Dermatology, 2022](https://pubmed.ncbi.nlm.nih.gov/35796638/)

### Where does this serum go in a skincare routine for oily acne-prone skin?

This serum goes in your evening routine as a treatment step after cleansing and before moisturizing. It provides moderate hydration for your oily skin without adding excess oil, but oily acne-prone skin also needs specialized ingredients to directly target acne, blemishes, and breakouts.

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

You can use this serum with retinol by applying the serum first to keep your skin calm and hydrated without adding excess oil. This type of routine benefits from including specialized blemish-clearing ingredients to properly address acne and breakouts.
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 your moisturizer. This frequency helps keep your oily skin comfortable and hydrated without adding excess oil, though an oily acne-prone skin also needs specialized ingredients to directly target breakouts.
Sources: [Health Science Reports, 2021](https://pubmed.ncbi.nlm.nih.gov/34141902/), [Dermatology, 2003](https://pubmed.ncbi.nlm.nih.gov/14571069/)

### Can this serum clog pores, cause breakouts or purging for oily acne-prone skin?

This serum is unlikely to clog pores or cause breakouts for your oily skin, as its soothing ingredients and lightweight humectants help maintain moisture without adding excess oil. However, because it lacks specialized ingredients to directly target blemishes, oily acne-prone skin needs products containing ingredients like salicylic acid, benzoyl peroxide, or retinoids to properly manage breakouts.

### 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 its gentle formula provides excellent skin tolerance without irritation. Regular application helps improve skin texture in delicate areas while keeping the skin soft and calm.
Sources: [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.
