## What the research says

- 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/))
- Optimized transfersomes loaded with epigallocatechin-3-gallate and hyaluronic acid increased cell viability while reducing lipid peroxidation, intracellular ROS, and MMP expression in HaCaT cells, and exhibited higher skin permeation and deposition compared to plain EGCG. ([Drug Delivery, 2017](https://pubmed.ncbi.nlm.nih.gov/28155509/))
- Combining oral and topical astaxanthin in 30 healthy females improved skin wrinkles, age spots, elasticity, texture, and moisture, while 6 mg daily oral supplementation in 36 healthy males improved crow's feet wrinkles, elasticity, and transepidermal water loss. ([Acta Biochimica Polonica, 2012](https://pubmed.ncbi.nlm.nih.gov/22428137/))
- Oral astaxanthin supplementation significantly restored moisture content and improved elasticity but did not significantly decrease wrinkle depth compared to placebo in humans. ([Nutrients, 2021](https://pubmed.ncbi.nlm.nih.gov/34578794/))
- 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/))

## Questions and answers

### How well does RoC Hydration + Serum work for dry skin?

RoC Hydration + Serum works reasonably well for dry skin, providing good moisture and antioxidant support through hyaluronic acid and glycerin. However, a top-rated product for dry skin needs extra barrier-supporting ingredients like ceramides and multiple types of hyaluronic acid to lock in moisture even more effectively.
Sources: [Dermatologic Therapy, 2022](https://pubmed.ncbi.nlm.nih.gov/36200921/)

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

Hyaluronic acid and erythritol make this moisturizing treatment a good fit by hydrating and plumping your dry skin. Glycerin and astaxanthin extract further support hydration and give antioxidant benefits, while a product of this type for dry skin also needs ceramides and rich moisturizing ingredients to lock in moisture and support the skin barrier.
Sources: [Acta Biochimica Polonica, 2012](https://pubmed.ncbi.nlm.nih.gov/22428137/)

### 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 does Hydrolyzed Haematococcus Pluvialis Extract do for dry skin?

Hydrolyzed Haematococcus Pluvialis Extract helps restore moisture to dry skin and keeps it feeling soft. It supports skin health by fighting oxidative stress.
Sources: [Nutrients, 2021](https://pubmed.ncbi.nlm.nih.gov/34578794/)

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

This moisturizing treatment goes in the evening routine after cleansing and before moisturizing, though products of this type for dry skin also need rich nourishing oils, butters, or ceramides to lock in deep moisture and protect the skin barrier.

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

You can use this moisturizing treatment in your evening routine after your cleanser, and then follow it with your moisturizer. To best care for dry skin, this type of product also needs richer oils or barrier-repairing ingredients like ceramides to lock in moisture and prevent flaking.

### How often should I use this moisturizing treatment?

You can use this moisturizing treatment in the evening as part of your routine. Daily application helps keep dry skin soft and smooth while supporting moisture levels.
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 moisturizing treatment clog pores, cause breakouts or purging for dry skin?

This moisturizing treatment is unlikely to clog pores or cause breakouts for dry skin. It contains gentle ingredients like hyaluronic acid and glycerin that hydrate the skin safely without harsh additives that typically cause irritation or breakouts.
Sources: [Dermatologic Therapy, 2022](https://pubmed.ncbi.nlm.nih.gov/36200921/)

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

You can use this moisturizing treatment around the eyes and on the body because it is safe and gentle for dry skin. However, since it is only an average fit, dry skin needs richer creams packed with extra plant oils and heavy sealing ingredients to stay truly soft and smooth.
Sources: [Surgical and Radiologic Anatomy, 2002](https://pubmed.ncbi.nlm.nih.gov/12375070/), [Polymers, 2023](https://pubmed.ncbi.nlm.nih.gov/37896378/)
