## Why this fit

- Offers moderate benefits for your dry skin, as Glycerin and Sodium Hyaluronate provide essential hydration and Hydrolyzed Wheat Protein and Hydrolyzed Soy Protein help repair the skin barrier. Acetyl Octapeptide-3 and Acetyl Hexapeptide-8 are present to address fine lines and wrinkles, though their impact on dryness may be limited.
- The formula is well-suited for dry skin due to its humectant and barrier-repairing ingredients, which contribute to overall skin health.
- The product is safe for your dry skin, containing no harsh or irritating 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/))
- Argireline treatment twice daily for 4 weeks produced a significant anti-wrinkle effect with 48.9% total efficacy and decreased skin roughness in Chinese subjects compared with 0% efficacy and no decrease in roughness in the placebo group. ([American Journal of Clinical Dermatology, 2013](https://pubmed.ncbi.nlm.nih.gov/23417317/))
- Treatment with cross-linked hyaluronic acid-based microneedle patches combined with acetyl hexapeptide-8 or epidermal growth factor significantly improved wrinkles and skin hydration compared to the patch alone in Korean females over 29 days. ([Annals of Dermatology, 2019](https://pubmed.ncbi.nlm.nih.gov/33911590/))
- Acetyl hexapeptide-3 and tripeptide-10 citrulline demonstrated antiwrinkle efficacy and decreased transepidermal water loss in twenty-four healthy volunteers compared to control groups, though synergistic effects between the two peptides remained unclear. ([Journal of Cosmetic Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28150423/))
- Daily topical acetyl hexapeptide-8 showed a trend toward a longer time until return to baseline Jankovic Blepharospasm Rating Scale scores compared to placebo (3.7 months vs. 3.0 months) in 24 patients with blepharospasm receiving botulinum toxin therapy. ([European Journal of Neurology, 2013](https://pubmed.ncbi.nlm.nih.gov/23146065/))
- Argireline applied twice daily for 4 weeks achieved a total anti-wrinkle efficiency of 48.9% and notably reduced wrinkle depth compared to placebo in Chinese subjects. ([Journal of Cosmetic and Laser Therapy, 2013](https://pubmed.ncbi.nlm.nih.gov/23607739/))
- 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/))
- Application of a cosmetic multiple emulsion containing vitamin C and wheat protein as well as a base formulation increased skin moisture in 11 human volunteers over four weeks, while producing no significant variations in skin sebum, pH, elasticity, melanin, or erythema. ([Pakistan Journal of Pharmaceutical Sciences, 2008](https://pubmed.ncbi.nlm.nih.gov/18166519/))
- The addition of polymers and hydrolysed proteins to model body wash cosmetics improves foaming properties, storage stability, and safety by reducing skin irritant potential, with the polyvinylpyrrolidone/hydrolysed wheat protein crosspolymer showing the strongest reduction effect. ([Colloids and Surfaces. B, Biointerfaces, 2015](https://pubmed.ncbi.nlm.nih.gov/26291586/))
- 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.

## Questions and answers

### How well does PCA SKIN ExLinea Pro Peptide Serum work for dry skin?

PCA SKIN ExLinea Pro Peptide Serum works moderately well for dry skin, offering basic hydration and barrier support from glycerin and sodium hyaluronate. While it helps smooth fine lines, dry skin generally needs richer ingredients like ceramides, niacinamide, and potent antioxidants to stay fully nourished and glowing.
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?

Glycerin and sodium hyaluronate provide essential hydration, while hydrolyzed wheat protein and hydrolyzed soy protein help repair the skin barrier for your dry skin. To fit dry skin even better, this type of product needs additional soothing ingredients, ceramides, niacinamide, or vitamin C for deep nourishment and a healthy glow.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

### What does Acetyl Octapeptide-3 do for dry skin?

Acetyl Octapeptide-3 helps keep dry skin calm and smooth by supporting skin firmness and reducing irritation. It is unlikely to cause irritation and is generally well tolerated when added to your daily routine.
Sources: [Journal of Drugs in Dermatology, 2025](https://pubmed.ncbi.nlm.nih.gov/39761149/)

### What does Argireline do for dry skin?

Argireline helps smooth out fine lines and reduce skin roughness when applied twice a day. It may also improve overall hydration, though it works best when paired with ingredients that deeply moisturize dry skin.
Sources: [American Journal of Clinical Dermatology, 2013](https://pubmed.ncbi.nlm.nih.gov/23417317/), [Journal of Cosmetic and Laser Therapy, 2013](https://pubmed.ncbi.nlm.nih.gov/23607739/)

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

This serum goes in your evening routine, after cleansing and before moisturizing. Putting treatments in the evening provides extra safety around sun exposure. Because your skin is dry, this product of this type needs added heavy hydrators and barrier-repairing ingredients like ceramides, squalane, or rich plant oils to truly soften and lock in moisture.

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

You can use this serum with retinol, applying the serum first and following it with your retinol product. This approach allows the hydrating ingredients to absorb well while helping keep your skin comfortable against potential dryness from the retinol.
Sources: [Journal of Cosmetic Dermatology, 2024](https://pubmed.ncbi.nlm.nih.gov/38102855/)

### How often should I use this serum?

This serum works best in your evening routine, applied after cleansing and before moisturizing. Dry skin needs a product with richer nourishing oils and heavy-duty moisture-locking ingredients to truly stay smooth and comfortable.
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 because it is safe and free of harsh or irritating ingredients. A product of this type needs rich moisturizing ingredients like glycerin and sodium hyaluronate along with barrier-repairing proteins to keep dry skin soft, smooth, and healthy.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

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

Yes, it has no fragrance and no drying alcohol.
