## 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 treatment of nicotinamide, alone or in combination with other active ingredients, reduces the progression of skin aging and hyperpigmentation in clinical trials while being well tolerated. ([Antioxidants, 2021](https://pubmed.ncbi.nlm.nih.gov/34439563/))
- 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 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.

## Questions and answers

### How well does Peter Thomas Roth Peptide Skinjection work for dry skin?

Peter Thomas Roth Peptide Skinjection works moderately well for dry skin, providing essential hydration through ingredients like hyaluronic acid and squalane while helping to keep your skin soft. A moisturizing treatment for dry skin needs rich hydrating ingredients and nourishing extracts to lock in moisture, smooth texture, and effectively soothe flakiness without any risk of irritation.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

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

This moisturizing treatment is a good fit for dry skin because ingredients like hyaluronic acid, squalane, and glycerin help provide essential hydration and support skin barrier repair. Dry skin of this type needs rich moisturizing agents, nourishing extracts, and soothing ingredients that deliver deep hydration and lock in moisture without causing irritation.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

### What does Glycerin do for dry skin?

Glycerin helps dry skin by drawing in moisture and keeping it locked in, which makes the skin feel much softer and smoother. It also supports your natural skin barrier to stop water from escaping easily. A product for dry skin needs extra ingredients like hyaluronic acid and soothing plant extracts to truly calm and hydrate dry patches.

### What does Tetrapeptide-1 do for dry skin?

Tetrapeptide-1 helps dry skin by improving the outer protective barrier and supporting moisture retention. It enhances skin thickness and helps keep the surface smooth and well-hydrated.
Sources: [International Journal of Cosmetic Science, 2013](https://pubmed.ncbi.nlm.nih.gov/23488645/)

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

This treatment goes in the evening routine after cleansing and before moisturizing, so you can apply it safely and simply. Dry skin of this type needs rich moisturizers with hyaluronic acid, glycerin, and squalane to deeply hydrate and repair the skin barrier.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

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

You can use this treatment alongside 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 rich, barrier-supporting ingredients like ceramides and rich plant oils to lock in moisture.
Sources: [Cutis, 2006](https://pubmed.ncbi.nlm.nih.gov/17121065/)

### How often should I use this treatment?

You can use this treatment in the evening as part of your routine. Daily application of this type of moisturizing treatment helps keep dry skin hydrated and comfortable.
Sources: [Health Science Reports, 2021](https://pubmed.ncbi.nlm.nih.gov/34141902/), [Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/32141711/)

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

This treatment is unlikely to clog pores or cause breakouts for dry skin, as its formula contains gentle hydrating ingredients and avoids harsh irritants. To care for dry skin even better, products of this type also need rich oils or butters that lock in moisture and deeply soften dry patches.

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

This treatment works for dry skin around the eyes and on the body because its moisturizing ingredients like glycerin, hyaluronic acid, and squalane hydrate and soothe delicate areas. To truly thrive, very dry skin needs richer creams packed with heavier barrier-repairing oils and butters.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

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

Yes, it has no fragrance and no drying alcohol.
