## 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/))
- 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/))
- 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/))
- 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/))
- Polyhexanide/betaine may be nontoxic and effective in enhancing wound healing, whereas the majority of other topical cleaning agents are locally toxic and of limited or no proven efficacy. ([Advances in Skin & Wound Care, 2013](https://pubmed.ncbi.nlm.nih.gov/23507692/))

## Questions and answers

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

This serum works moderately well for dry skin, providing basic moisture and comfort without causing irritation. A product of this type needs richer moisturizing agents and barrier-supporting ingredients to give dry skin deep hydration, nourishment, and optimal moisture retention.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

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

Sodium hyaluronate, glycerin, and betaine help plump and moisturize dry skin, while ceramide NP supports the skin barrier for added comfort. A product of this type needs a rich blend of deep hydration ingredients and nourishing extracts to effectively address dryness and keep the skin soft and radiant.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

### 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.
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/)

### What do Ceramides do for dry skin?

Ceramides help strengthen your skin barrier and lock in moisture to keep dry skin feeling soft and smooth. By restoring essential lipids, they may also reduce water loss and soothe irritation.
Sources: [The British Journal of Dermatology, 2022](https://pubmed.ncbi.nlm.nih.gov/34921679/), [Dermatologic Therapy, 2019](https://pubmed.ncbi.nlm.nih.gov/31585489/)

### 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 and skin-softening ingredients like glycerin, sodium hyaluronate, and ceramides to plump the skin and support the protective barrier.
Sources: [The Journal of Dermatological Treatment, 2022](https://pubmed.ncbi.nlm.nih.gov/32239984/), [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 at night to help keep your skin comfortable and hydrated. This type of product works well for dry skin when it includes soothing ingredients and moisture-locking helpers like glycerin, sodium hyaluronate, and ceramides.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

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

This serum is unlikely to clog pores or cause breakouts for dry skin, as its formula is generally safe and free of harsh ingredients that typically cause irritation. To give dry skin the best care, this skin type needs richer creams with nourishing oils and heavier butters to lock in moisture.
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 safely use this serum around the eyes and on the body because its gentle formula provides good moisturizing effects without harsh ingredients. Dry skin in these areas generally needs products with rich hydrators like glycerin and sodium hyaluronate, along with barrier-supporting ceramides, to maintain comfort.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)
