## What the research says

- 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/))
- Topical sunscreen formulations containing UV filters, red algae extract, Ginkgo biloba, and vitamins protected hairless mice from UV-induced erythema, reduced transepidermal water loss, and significantly decreased the expression of p53 and caspase-3 compared to untreated controls. ([Journal of Photochemistry and Photobiology. B, Biology, 2015](https://pubmed.ncbi.nlm.nih.gov/26402714/))
- Chitosan/polyvinyl alcohol nanofibrous dressings containing 3% Corallina officinalis extract exhibited bead-free morphology, enhanced mechanical strength, strong antibacterial activity against Escherichia coli and Staphylococcus aureus, and excellent biocompatibility for skin cell survival and proliferation. ([Journal of Biomaterials Science. Polymer Edition, 2026](https://pubmed.ncbi.nlm.nih.gov/40742752/))
- A skincare regimen containing Macrocystis pyrifera ferment consisting of a cleansing foam, a serum, and a moisturizer decreases the visible effects of inflammation and aging while promoting healing and improving patient satisfaction. ([Journal of Cosmetic Dermatology, 2024](https://pubmed.ncbi.nlm.nih.gov/38922798/))
- Macrocystis pyrifera ferment-containing creams decrease visible inflammation and signs of aging while enhancing barrier resilience and recovery. ([Journal of Cosmetic Dermatology, 2023](https://pubmed.ncbi.nlm.nih.gov/38041526/))
- Aqueous extracts from Macrocystis pyrifera and Durvillaea antarctica exhibited antiviral activity against acyclovir-sensitive and acyclovir-resistant HSV-1 and HSV-2, and topical formulations significantly reduced the severity and duration of HSV-1 skin lesions in an animal model compared to mock treatment and acyclovir. ([Frontiers in Microbiology, 2020](https://pubmed.ncbi.nlm.nih.gov/33013743/))

## Why other moisturizers fit oily skin better

- 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/))
- 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/))

## Questions and answers

### How well does OSEA Hyaluronic Sea Serum work for oily skin?

OSEA Hyaluronic Sea Serum offers moderate hydration for oily skin, as sodium hyaluronate moisturizes without adding excess oil, while marine extracts provide soothing benefits. A product of this type needs oil-regulating ingredients like Niacinamide or oil-controlling agents, alongside lightweight moisture, to fully meet the needs of oily skin.

### Which ingredients make this serum a good fit for oily skin?

Sodium hyaluronate makes this serum a good fit for oily skin because it moisturizes without adding excess oil, while seaweed extracts help calm the skin. To work even better for oily skin, a product of this type needs ingredients like Niacinamide to help control oil and minimize pores.
Sources: [International Journal of Biological Macromolecules, 2025](https://pubmed.ncbi.nlm.nih.gov/39880261/), [Marine Drugs, 2024](https://pubmed.ncbi.nlm.nih.gov/39728136/)

### What does Hyaluronic Acid do for oily skin?

Hyaluronic acid helps oily skin by reducing extra oil and sebum production without causing irritation. Clinical studies show it successfully balances oil levels while keeping the skin comfortable.
Sources: [The Journal of Investigative Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28163068/)

### What does Marine Extract do for oily skin?

Marine extract helps balance and hydrate oily skin without feeling heavy or greasy. It may also improve overall skin texture and smoothness while keeping excess shine under control.
Sources: [Journal of Cosmetic Dermatology, 2023](https://pubmed.ncbi.nlm.nih.gov/35426243/)

### Where does it go in a skincare routine for oily skin?

This treatment goes in your evening routine, as treatments with active ingredients are used then for simplicity and extra safety around sun exposure. It provides moderate hydration for oily skin without adding excess oil, though an oily skin routine also needs stronger oil-balancing ingredients.

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

You can use this serum with retinol by applying the serum first to hydrate your skin, followed by your retinol treatment. A product of this type needs stronger oil-balancing ingredients to be a great fit for oily skin.

### How often should I use it?

You can use this treatment in your evening routine. Oily skin benefits from stronger oil-controlling ingredients to work even better with this product type.

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

This serum is unlikely to clog pores or cause breakouts on oily skin, as it provides hydration without adding excess oil. However, because it is only an average fit for oily skin, a product of this type needs stronger oil-balancing ingredients to better manage shine and prevent breakouts.
Sources: [International Journal of Biological Macromolecules, 2025](https://pubmed.ncbi.nlm.nih.gov/39880261/), [Marine Drugs, 2024](https://pubmed.ncbi.nlm.nih.gov/39728136/)

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

This product is safe to use around the eyes and on the body, as it contains gentle seaweed extracts and sodium hyaluronate with a very good safety profile. It helps keep these areas calm and hydrated without adding excess oil, though oily skin on the body benefits most from added ingredients that help control shine.

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

Yes, it has no fragrance and no drying alcohol.
