What Is Ulva Ramulosa Callus Culture Extract?
Ulva Ramulosa Callus Culture Extract comes from Ulva ramulosa, a green seaweed that naturally grows in coastal waters. Scientists take a small sample of the plant, place it in a sterile nutrient solution, and encourage the cells to grow into a soft mass called a callus. From this lab-grown callus they collect and purify the extract. Because the process happens in a controlled setting, the final ingredient is free from ocean pollutants and seasonal changes.
The extract holds a mix of sugars, amino acids, vitamins, and minerals that seaweed cells naturally produce to keep themselves hydrated and protected against stress. These same compounds can help support the skin’s surface. Ulva Ramulosa Callus Culture Extract first gained attention as brands looked for sustainable marine ingredients that could be produced without harvesting large amounts of wild seaweed. Lab cultivation answered that need, letting formulators tap into seaweed benefits while protecting ocean ecosystems.
Today you will find this ingredient in a range of products: hydrating sheet masks, daily moisturizers, soothing after-sun gels, anti-aging serums, and lightweight eye creams. Its gentle nature makes it suitable for leave-on and rinse-off formulas alike.

Comedogenic Rating
Rating: 0/5
Ulva Ramulosa Callus Culture Extract is a water based botanical with virtually no lipids or waxes that could clog pores. Its molecules sit lightly on the skin and rinse away easily so it earns the lowest comedogenic score.
Because it does not add oil or create an occlusive layer this extract is generally suitable for people who are prone to acne or frequent breakouts.
The only time pore issues might arise is if the extract is blended into a very heavy cream rich in butters or silicones. In that case the overall formula, not the extract itself, would be the likely culprit.
Summary
Ulva Ramulosa Callus Culture Extract mainly conditions the skin. Its natural sugars and amino acids form a light film that slows water loss and keeps the surface feeling soft and supple. Minerals and vitamins also support a balanced skin barrier, helping calm dryness and minor irritation.
The ingredient sits in the “up and coming” category. It appears in sustainability focused lines and niche marine inspired serums but is not yet a household name like hyaluronic acid.
Safety data shows it is low risk for most users, including those with sensitive skin, since it is free of common irritants and produced in a controlled lab setting. Still it is smart to patch test any new product to rule out personal sensitivities before applying it more broadly.
