This fit is calculated for the concerns frequently associated with mature skin: fine lines, wrinkles, and loss of firmness. For scores based on a full skin profile (12D face scan, goals, preferences), use the Lovi app.

Works for mature skin; other moisturizers fit it better.

## Why this fit

- Offers moderate suitability for normal skin, as glycerin and sodium hyaluronate provide excellent hydration to plump fine lines and wrinkles.
- While the humectant action is strong, the formula lacks sufficient emollient ingredients like ceramides or cholesterol to fully address potential dryness.
- The product is generally safe for your skin, though the presence of alcohol and lactic acid may pose a slight 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/))
- 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/))
- 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/))
- 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/))

## Why other moisturizers fit mature skin better

- Daily consumption of fermented pomegranate extract drinks and serums improved skin moisture, brightness, elasticity, and collagen density while reducing spots in healthy subjects compared to baseline. ([Journal of Cosmetic Dermatology, 2022](https://pubmed.ncbi.nlm.nih.gov/34416060/))
- Sodium trehalose sulfate decreased transepidermal water loss and increased stratum corneum water content in participants with low stratum corneum water content when applied for 4 weeks compared to placebo. ([Skin Research and Technology, 2024](https://pubmed.ncbi.nlm.nih.gov/38606717/))
- Aged Punica granatum extract significantly reduced UV-induced erythema and melanin levels while improving skin hydration and lightness compared to placebo in 60 women. ([Food Science & Nutrition, 2025](https://pubmed.ncbi.nlm.nih.gov/40755496/))

## How to apply

- Use your moisturizer twice a day in your AM and PM routines. Apply it daily to help smooth fine lines.
- 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.
- Apply the moisturizer on slightly damp skin to help lock in extra moisture. Clean skin helps the product absorb much more evenly.
- Avoid the sensitive eye area during application. Do a quick patch test before your very first use to stay safe.

## Questions and answers

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

This serum works moderately well for mature skin because glycerin and sodium hyaluronate hydrate the skin and help plump fine lines. However, it lacks enough softening ingredients to fully address dryness, and alcohol and lactic acid may cause a slight risk of irritation. A product of this type needs richer softening ingredients and nourishing actives to properly care for mature skin.
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?

Sodium hyaluronate and glycerin make this serum a good fit for mature skin by delivering strong hydration that helps plump fine lines and wrinkles. However, because this formula lacks richer smoothing ingredients to fully address potential dryness, mature skin of this type needs added nourishing oils and butters for best results.
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 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/)

### What do Ceramides do for mature skin?

Ceramides help keep mature skin feeling soft and smooth by strengthening the moisture barrier and locking in hydration. This type of skin needs ingredients that rebuild lost moisture and protect against dryness to stay comfortable.
Sources: [Experimental Dermatology, 2025](https://pubmed.ncbi.nlm.nih.gov/39912256/), [American Journal of Clinical Dermatology, 2003](https://pubmed.ncbi.nlm.nih.gov/12553851/)

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

This serum goes in the evening routine after cleansing and before moisturizing. Mature skin of this type needs rich moisturizing ingredients like heavier ceramides and cholesterol to lock in hydration and smooth dryness.

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

You can use this serum with retinol by applying it right before your moisturizer in your evening routine. Using a product that boosts hydration helps support mature skin during retinol use, though this serum needs more nourishing softeners like ceramides and cholesterol to fully prevent dryness.
Sources: [Cutis, 2006](https://pubmed.ncbi.nlm.nih.gov/17121065/), [Dermatologic Therapy, 2022](https://pubmed.ncbi.nlm.nih.gov/36200921/)

### How often should I use this serum?

You can use this serum in your evening routine, applying it after cleansing and toning and before your moisturizer. It is generally safe for your skin, though alcohol and lactic acid may pose a slight risk of irritation.
Sources: [Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/32141711/), [Journal of Drugs in Dermatology, 2015](https://pubmed.ncbi.nlm.nih.gov/26151786/)

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

This serum is unlikely to clog pores or cause breakouts for mature skin, though alcohol and lactic acid present in the formula may pose a slight risk of irritation. A product of this type needs richer emollient ingredients like ceramides and cholesterol to fully address potential dryness and support mature skin.

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

This serum is safe to use on the thin skin around your eyes and on your body, though it is thin and requires extra softening ingredients to fully care for dry areas. A product of this type needs rich softening ingredients like ceramides and cholesterol to lock in moisture and keep mature skin smooth and comfortable.
Sources: [Surgical and Radiologic Anatomy, 2002](https://pubmed.ncbi.nlm.nih.gov/12375070/)

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

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