## 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/))
- Emulsions containing ceramides 1 and 3 improved skin hydration and reduced transepidermal water loss in sodium lauryl sulfate-irritated skin of fifteen healthy Asian women compared to a control emulsion. ([International Journal of Dermatology, 2008](https://pubmed.ncbi.nlm.nih.gov/18717861/))
- A combination of Aloe barbadensis leaf extract and trimethylglycine in a 1:1 mass ratio synergistically increased aquaporin 3 expression by up to 380% in keratinocytes and safely improved skin hydration in healthy volunteers. ([Molecules, 2024](https://pubmed.ncbi.nlm.nih.gov/38611819/))
- 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/))
- Topical dry mouth products containing olive oil, betaine, and xylitol significantly increased unstimulated whole salivary flow rates, reduced xerostomia complaints, and improved quality of life in adults with polypharmacy-induced xerostomia compared to their normal routine care, with no clinically significant adverse events. ([Journal of Oral Rehabilitation, 2007](https://pubmed.ncbi.nlm.nih.gov/17824884/))
- Soaps containing betaine caused the least skin irritation compared to other tested soaps in twenty-eight healthy subjects, though irritation did not decrease with increasing concentrations of betaine. ([Skin Research and Technology, 2003](https://pubmed.ncbi.nlm.nih.gov/12535284/))
- Mixed surfactant systems of sodium dodecyl sulfate and dimethyl dodecyl amido betaine significantly reduce acute skin irritation potential in human volunteers compared with the individual surfactants, demonstrating that irritation potential cannot be predicted by simple summation. ([Food and Chemical Toxicology, 1998](https://pubmed.ncbi.nlm.nih.gov/9609395/))

## Questions and answers

### How well does COSRX The Hyaluronic Acid 3 Serum work for dry sensitive skin?

This serum works reasonably well for dry sensitive skin by providing moderate hydration and supporting your skin barrier, though it is unlikely to fully resolve severe dryness or flakiness. A product of this type needs a blend of effective hydrating and soothing ingredients, such as multiple forms of hyaluronic acid and barrier-supporting ceramides, to deliver intense nourishment and lasting comfort without any risk of irritation.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

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

Sodium hyaluronate and glycerin help provide essential hydration, while ceramide NP and cholesterol help support your skin barrier. To truly soothe very dry or flaky skin, this type of product needs a rich blend of intense hydrators and soothing extracts that deeply nourish and protect the skin barrier.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

### What does Hyaluronic Acid do for dry sensitive skin?

Hyaluronic acid is a great fit for dry, sensitive skin because it brings a large boost in hydration, making the skin feel soft and smooth while improving barrier function. It helps calm tightness and dryness, and is unlikely to cause irritation.
Sources: [Journal of Drugs in Dermatology, 2011](https://pubmed.ncbi.nlm.nih.gov/22052267/), [Dermatology and Therapy, 2021](https://pubmed.ncbi.nlm.nih.gov/34176098/)

### What do Ceramides do for dry sensitive skin?

Ceramides help hydrate dry sensitive skin and strengthen its outer barrier to reduce water loss and calm irritation. Using a product with ceramides often improves skin comfort and makes the skin feel much softer.
Sources: [International Journal of Dermatology, 2008](https://pubmed.ncbi.nlm.nih.gov/18717861/)

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

This serum goes in the evening routine after your toner and before your moisturizer. It provides basic hydration and is generally safe for your skin, but dry skin often needs richer barrier-repairing creams with higher levels of ceramides and nourishing oils for deeper comfort.

### 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 hydrated and help calm irritation. This product type works well for this skin when it includes richer barrier-supporting ingredients and deeper hydrators to tackle severe dryness.
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. While it provides good basic hydration for dry and sensitive skin, this skin type needs deeper hydration and richer barrier-repair ingredients like ceramides, fatty acids, and nourishing oils to fully address severe dryness.
Sources: [Health Science Reports, 2021](https://pubmed.ncbi.nlm.nih.gov/34141902/), [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

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

This serum is unlikely to clog pores or cause breakouts for dry and sensitive skin, as its formula is generally safe with no harsh ingredients. However, because this is an average fit, dry skin needs a product that also includes richer oils and heavier butters to deeply soften and lock in moisture.

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

You can use this serum around the eyes and on the body, as the thin skin of the eyelids and various body regions tolerate gentle moisturizing treatments well. Sodium Hyaluronate, glycerin, and ceramide NP help hydrate these areas safely, though drier skin types needing advanced care may want a richer product with heavier oils and stronger barrier builders.
Sources: [Surgical and Radiologic Anatomy, 2002](https://pubmed.ncbi.nlm.nih.gov/12375070/), [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

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

It has no fragrance and contains drying alcohol (alcohol).
