## Questions and answers

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

This serum offers moderate moisture for your combination skin, using sodium hyaluronate to hydrate without leaving oily shine. A product of this type needs effective hydrating and skin-repairing ingredients like ceramides, hyaluronic acid, peptides, and niacinamide to balance moisture and oil levels without irritation.
Sources: [Journal of Pharmacy & Pharmaceutical Sciences, 2015](https://pubmed.ncbi.nlm.nih.gov/25877441/)

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

Sodium hyaluronate and seaweed extracts make this serum a good fit because they provide hydration without being heavy, helping to keep your skin soft and smooth while managing oily shine. To work even better for combination skin, a product of this type needs additional ingredients like ceramides, peptides, or niacinamide for balanced moisture and oil control.
Sources: [Journal of Pharmacy & Pharmaceutical Sciences, 2015](https://pubmed.ncbi.nlm.nih.gov/25877441/), [Dermatologic Therapy, 2022](https://pubmed.ncbi.nlm.nih.gov/36200921/)

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

Hyaluronic acid is a great fit for combination skin because it quenches dry areas with a boost of hydration while keeping oily zones balanced. Regular use helps smooth out fine lines and makes your skin feel soft and plump without causing irritation.
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 Marine Extract do for combination skin?

Marine extract helps keep combination skin smooth and hydrated while balancing dry and oily areas. It provides antioxidant and calming benefits that support overall skin health with a low risk of irritation.
Sources: [Journal of Cosmetic Dermatology, 2023](https://pubmed.ncbi.nlm.nih.gov/35426243/), [Carbohydrate Polymers, 2025](https://pubmed.ncbi.nlm.nih.gov/39914982/)

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

This treatment goes in your evening routine, applied after cleansing and before your moisturizer. Combination skin needs products with light hydrating ingredients like sodium hyaluronate and seaweed extracts to manage oily shine without heavy layers.

### 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 before putting on your retinol. This approach helps keep your skin comfortable and is unlikely to cause irritation.
Sources: [Cutis, 2006](https://pubmed.ncbi.nlm.nih.gov/17121065/)

### How often should I use this serum?

This serum works well in your evening routine, but some treatments can also be used in the morning or twice a day. It offers moderate moisture for your combination skin without feeling heavy, helping you manage oily shine.
Sources: [Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/32141711/), [Health Science Reports, 2021](https://pubmed.ncbi.nlm.nih.gov/34141902/)

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

This serum is unlikely to clog pores or cause breakouts on combination skin because sodium hyaluronate hydrates without using heavy, pore-blocking ingredients. It is also gentle and safe, with no harsh ingredients that typically cause irritation. To get a better fit for combination skin, a product of this type needs lightweight hydrators paired with ingredients that help balance oily shine.
Sources: [Journal of Pharmacy & Pharmaceutical Sciences, 2015](https://pubmed.ncbi.nlm.nih.gov/25877441/), [Dermatologic Therapy, 2022](https://pubmed.ncbi.nlm.nih.gov/36200921/)

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

You can use this serum around your eyes, as it has a very safe profile and sodium hyaluronate is well-tolerated on delicate skin, but it is not specifically formulated for broader body use. For the thin skin around your eyes and dry areas on the body, a product of this type needs richer nourishing ingredients and intensive moisturizers to properly support and soften those areas.

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

Yes, it has no fragrance and no drying alcohol.
