Haslea Ostrearia Extract is derived from the alga Haslea ostrearia, which belongs to the Naviculaceae family. This unique marine organism is often referred to as the “blue diatom” due to its distinctive blue-green pigmentation. The extract is rich in various bioactive compounds, including pigments, polysaccharides, and other organic molecules that contribute to its skin-conditioning properties.
Historically, Haslea ostrearia has been studied for its role in the marine ecosystem, particularly in oyster farming, where it imparts a blue-green hue to the gills of oysters, a phenomenon known as “greening.” Its journey into the cosmetic industry began when researchers identified its potential benefits for skin health, leading to its incorporation into skincare formulations.
The extraction process typically involves harvesting the algae from its natural marine environment, followed by a series of purification steps to isolate the desired bioactive compounds. This ensures that the final extract is both potent and safe for use in cosmetic products.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Haslea Ostrearia Extract:
Haslea Ostrearia Extract is primarily known for its skin conditioning properties. This means that it helps to maintain the skin in good condition. When included in cosmetic formulations, it can help to improve the appearance and feel of the skin, making it softer, smoother, and more supple.

Note: the listed benefits above are exclusively based on the officially recognized and defined functions of the ingredient, as documented by the International Nomenclature of Cosmetic Ingredients (INCI).
Haslea Ostrearia Extract is generally considered safe for topical application in cosmetic products. However, as with any ingredient, there are potential side effects that users should be aware of:
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Haslea Ostrearia Extract during pregnancy and breastfeeding are lacking. Therefore, it is recommended that they consult a healthcare professional for further advice.
Adverse reactions to Haslea Ostrearia Extract are relatively uncommon, but it is always prudent to perform a patch test before widespread use to ensure there is no sensitivity or allergic reaction.
In terms of comedogenicity, Haslea Ostrearia Extract scores a 1 on a scale of 0 to 5, where 0 is totally non-comedogenic and 5 is highly comedogenic. This low score indicates that it is unlikely to clog pores, making it suitable for individuals prone to acne, blemishes, or breakouts.
