What is Laminaria Ochroleuca Extract and what does it do in sunscreen?

Laminaria Ochroleuca Extract comes from a golden-brown seaweed, a marine algae. In skincare it is valued as a soothing, conditioning botanical that helps calm and hydrate the skin. In a sunscreen it is a supporting ingredient for skin comfort and feel rather than part of the UV protection. You will often see it in moisturizing and anti-aging SPF formulas.

What else is Laminaria Ochroleuca Extract called?

Laminaria Ochroleuca is the botanical name of a golden-brown seaweed, so this is essentially a golden algae or seaweed extract. On a label it appears as the INCI name Laminaria Ochroleuca Extract. Brands may describe it in marketing as a marine or algae extract, but the INCI form is what is printed in the ingredient list.

Is Laminaria Ochroleuca Extract safe?

Generally yes. It is a marine botanical extract used at low levels for soothing and conditioning, and it is widely used in cosmetics without notable concern for most people. Our data does not flag it as an allergen. As with any botanical, a patch test is sensible if your skin is easily sensitized.

Does Laminaria Ochroleuca Extract clog pores?

Generally no. It is a water-based algae extract used in small amounts, not a heavy oil or wax, so it is an unlikely pore-clogging culprit, and our data does not flag it as comedogenic. If a product breaks you out, richer emollients elsewhere in the formula are the more likely cause.

Is Laminaria Ochroleuca Extract vegan?

Yes. It is derived from seaweed, a marine plant-like algae, with no animal-derived material, so the ingredient itself suits vegan formulas. Whether a finished sunscreen is fully vegan still depends on its other ingredients.
