What Is Hydrolyzed Ulva Pertusa Extract?
Hydrolyzed Ulva Pertusa Extract comes from Ulva pertusa, a green seaweed that thrives along temperate coastlines in East Asia and parts of Europe. Rich in natural sugars, proteins and trace minerals, this algae has long been eaten in coastal cuisines and valued in folk beauty routines for its skin-softening feel. Modern cosmetic science takes dried Ulva pertusa and subjects it to controlled hydrolysis, usually with gentle acids or skin-friendly enzymes. This breaks the large native molecules into smaller fragments that dissolve readily in water and can penetrate the skin’s surface more easily.
The resulting liquid or powder has a light marine scent and a low to medium viscosity, making it simple to add at the cool-down phase of production. You will spot Hydrolyzed Ulva Pertusa Extract in hydrating sheet masks, daily moisturizers, soothing after-sun gels, anti-aging serums and leave-on lotions designed to calm sensitive or freshly exfoliated skin.
Hydrolyzed Ulva Pertusa Extract’s Cosmetic Benefits/Uses
Formulators choose this algae derivative mainly for one key reason
Skin conditioning: The hydrolyzed proteins and polysaccharides form a lightweight film that attracts and holds moisture, leaving the complexion feeling smoother, plumper and less tight. Over time regular use can support a more supple appearance and help ease minor dryness or rough patches while adding a soft touch to the overall formula’s texture.
Who Can Use Hydrolyzed Ulva Pertusa ExtractThis ingredient suits most skin types including normal, dry and oily as its light film-forming sugars and proteins hydrate without leaving a heavy residue. Sensitive complexions usually tolerate it well thanks to its gentle marine origin, though anyone with a known seaweed or iodine allergy should avoid it.
Because it is derived from plant-based seaweed and processed without animal derivatives, Hydrolyzed Ulva Pertusa Extract is appropriate for vegans and vegetarians.
No specific warnings exist for pregnancy or breastfeeding, and topical use is not thought to affect hormonal pathways, yet this is not medical advice and those who are pregnant or nursing should ask their doctor before adding any new skincare product.
The extract does not heighten photosensitivity so it can be used morning or night without increasing the risk of sunburn. There are no known conflicts with common actives like retinol or vitamin C, making it easy to slot into most routines.
Potential Side Effects/Adverse Reactions
Responses to Hydrolyzed Ulva Pertusa Extract vary from person to person. The points below outline possible but uncommon reactions; most users experience none of these when the ingredient is included at standard cosmetic levels.
- Redness or mild stinging on very reactive or broken skin
- Contact dermatitis in individuals allergic to algae or iodine
- Occasional blemishes in those highly prone to acne if the finished formula is too occlusive
- Exacerbation of thyroid concerns if large areas of broken skin are repeatedly treated in those with extreme iodine sensitivity
- Rare contamination-related irritation if the extract is sourced from polluted waters containing heavy metals
If any discomfort or unusual reaction occurs stop use immediately and seek advice from a healthcare professional or dermatologist.
Comedogenic Rating
Rating: 1 / 5
Hydrolyzed Ulva Pertusa Extract is mostly water soluble and leaves only a light, breathable film on the skin so it is very unlikely to block pores. It contains no heavy oils or waxes that typically trigger comedones. This makes it generally suitable for those prone to acne or breakouts. If the finished formula also includes rich butters or occlusive silicones that could raise the overall pore-clogging potential, check the full ingredient list.
Summary

Safety profiles are strong with low irritation reports and a minimal comedogenic footprint. Still, skin is personal so perform a patch test when trying any new product that lists this extract near the top of the label.
