A: Algenist does not conduct animal testing, nor ask others to test on our behalf, unless required by law, regulation, or a governmental authority. We are committed to ethical practices and procedures through the entire process of product development – from R&D, to manufacturing, and to every step of the value chain; we rigorously vet our ingredient suppliers to ensure they share the same values and beliefs of non-animal testing. The safety and efficacy of our products are evaluated by clinical (non-animal) methods with volunteer human panels. As Algenist continues to expand and reach our customers around the globe, our support and commitment to eliminate animal testing is stronger than ever. Therefore, we are proud to share our partnership with the Institute for In Vitro Sciences (IIVS), a non-profit research organization dedicated to adoption and regulatory acceptance of alternative methods to animal testing worldwide.

A: We use a variety of fragrances in our products to further enhance the experience of our Algenist collections, however, these fragrances are used at very low levels. We thoroughly test all of our products to insure they are safe for consumer use. We offer both fragranced and unfragranced products within our line, due to feedback from our customers requesting both options. If there is a hyper-sensitivity to allergens or a preference not to use fragranced products, we suggest our Gentle Rejuvenating Cleanser, Regenerative Anti-Aging Moisturizer, Regenerative Anti-Aging Moisturizer SPF 20, Regenerative Anti-Aging Ultra Rich Cream, Targeted Deep Wrinkle Minimizer, Lip Renewal Balm and any of our eye creams.


A: Microalgae are, like their name denotes, microscopic forms of algae—amazing, single cell organisms that thrive in both fresh and salt-water environments, but unlike their larger counterparts, do not have roots, stems, or leaves.

A: No, different strains of microalgae are used to produce fuels and Alguronic Acid. Individual strains are chosen based on their ability to produce the desired oils and compounds efficiently and at large scale.

A: Algae are a large and diverse group of generally multicellular organisms, the largest and most well known of which is seaweed. Blue, green, and red algae all fall into this category. Alguronic Acid is not algae at all, rather a compound that is naturally produced by microalgae—amazing, single cell organisms that thrive in both fresh and salt-water environments, but unlike their larger counterparts, do not have roots, stems, or leaves. Whereas other skincare products use blue, green, or red algae as a direct ingredient, Algenist products use the powerful and rare microalgae-derived compound Alguronic Acid. Alguronic acid is made into a highly effective anti-aging skincare ingredient via a highly refined, 5 phase, 15-step extraction and purification process.

Alguronic Acid

A: Alguronic Acid is a group of complex polysaccharides, produced by specific strains of microalgae that function to protect and regenerate the microalgae cell. The team of biotechnology scientists behind Algenist developed a highly advanced process that allows us to grow microalgae and extract the patented Alguronic Acid compound.

A: After years of research into microalgae as a renewable energy source, our biotechnology scientists unexpectedly discovered a powerful protective and regenerative compound with incredible anti-aging properties known as Alguronic Acid.

A: Alguronic Acid was unexpectedly discovered by a team of scientists at a San Francisco based biotechnology company focused on the development of renewable energy solutions from microalgae. While researching thousands of microalgae strains, the biotechnology scientists identified a protective and regenerative polysaccharide compound produced by certain strains of microalgae that, when isolated and tested, showed significant anti-aging properties.

A: Alguronic Acid was discovered through researching thousands of microalgae strains over four years.

A: Alguronic Acid, a complex polysaccharide, is naturally produced by microalgae. Algenist utilizes a detailed, multi-phase proprietary extraction and purification process that allows for the isolation of Alguronic Acid from other microalgal cellular components.

A: Polysaccharides are carbohydrate structures consisting of repeating units joined together.

A: Alguronic Acid is a highly protective and regenerative compound that surrounds the microalgae cell.

A: Alguronic Acid is a purified microalgae exopolysaccharide extract. Alguronic Acid’s major anti-aging benefits for the skin are the same as those provided to microalgae cells by these powerful polysaccharide compounds.
