This fit is calculated for the concerns frequently associated with oily acne-prone skin: shine, breakouts, blemishes, and enlarged pores. For scores based on a full skin profile (12D face scan, goals, preferences), use the Lovi app.

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

## Why this fit

- Offers moderate hydration for your oily skin, as sodium hyaluronate and glycerin provide excellent humectant benefits without increasing oiliness.
- 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, with no risks of irritation 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/))
- 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/))

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

- 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/))
- A panthenol-enriched mask improved skin hydration, regulated sebum, and reduced redness and TEWL across dry sensitive, oily sensitive, and oily acne skin subgroups with excellent tolerance and no adverse reactions. ([Journal of Cosmetic Dermatology, 2024](https://pubmed.ncbi.nlm.nih.gov/38366684/))

## Questions and answers

### How well does COSRX Hyaluronic Acid 3 work for oily acne-prone skin?

This serum works moderately well for oily skin by offering lightweight hydration without increasing oiliness or causing irritation, but it lacks specific ingredients to target acne and breakouts. To truly thrive, oily acne-prone skin needs specialized ingredients like Niacinamide or soothing agents to actively clear blemishes, regulate oil production, and balance 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?

Sodium hyaluronate and glycerin make this serum a good fit by providing moderate hydration without increasing oiliness. A product of this type needs ingredients like niacinamide to help target acne, regulate oil production, and minimize pores for this skin.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

### 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/)

### What do Ceramides do for oily acne-prone skin?

Ceramides help keep oily acne-prone skin calm and smooth by strengthening the skin barrier and locking in moisture. Since acne-prone skin often has lower levels of these natural lipids, adding ceramides helps reduce irritation, redness, and moisture loss. A product for this skin type needs barrier-supporting ingredients like ceramides and gentle hydrators to prevent dryness and balance oil.
Sources: [Journal of Cosmetic Dermatology, 2026](https://pubmed.ncbi.nlm.nih.gov/41749022/), [Journal of Cosmetic Dermatology, 2023](https://pubmed.ncbi.nlm.nih.gov/37605504/)

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

This treatment goes in the evening routine after cleansing and before moisturizing. Oily acne-prone skin needs a product of this type that also includes ingredients to directly target breakouts and blemishes.

### 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 keep your skin soft and comfortable while reducing the dryness and irritation retinol may cause. This product type works well for oily acne-prone skin when it includes soothing ingredients and acne-fighting components to help clear blemishes.
Sources: [Cutis, 2006](https://pubmed.ncbi.nlm.nih.gov/17121065/), [Journal of Drugs in Dermatology, 2012](https://pubmed.ncbi.nlm.nih.gov/22648223/)

### How often should I use this serum?

This serum works well in your evening routine, where you can apply it daily to keep your oily skin feeling soft and comfortable without increasing oiliness. Oily acne-prone skin often needs targeted ingredients like salicylic acid or niacinamide to help clear blemishes and prevent breakouts.

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

This serum is unlikely to cause breakouts or clog pores on oily acne-prone skin because it avoids harsh or irritating ingredients. However, it lacks specialized ingredients to directly target acne and blemishes, so a product for this skin needs added blemish-fighting ingredients and oil-balancing components.
Sources: [Skin Research and Technology, 2003](https://pubmed.ncbi.nlm.nih.gov/12535284/)

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

You can use this serum safely around the eyes, though the skin there is much thinner than on the body. Its moisturizing ingredients hydrate these delicate areas well, but this skin type needs targeted anti-aging or barrier-repairing ingredients for best results.
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?
