[INGREDIENT BACKGROUND] Comparing Different Types of Marine Algae

by When Beauty on June 10, 2021

The first thing you think of when someone mentions seaweed, is that you probably consider them as underwater plants—but actually, they’re not. Although they do have some similar characteristics with land plants like using chlorophyll for photosynthesis and having cell walls that are plant-like, they don’t have any roots nor do they produce seeds. 

In our previous blog, we talked about our WHEN REVIVIFYING Anti-Aging skincare line’s key active ingredient SEANOL®, which is derived from brown algae or more commonly known as seaweed. But did you also know that there is more than one type of marine algae?

<The Three Types>

 Red Algae: Rhodophyta


Red algae are mostly located in the sea and live at greater depths compared to brown or green algae because it absorbs blue light. There are about 7,000 species of red algae of different shapes and sizes. Coraline algae, a subgroup of red algae, is important in the formation of coral reefs. The pigment, phycoerythrin, provides the bright and vivid hue uniquely attributed to red algae. Red algae contain high quantities of sulfated polysaccharides, peptides, carotenoids, and fatty acids, and thus help to improve skin elasticity and smooth out uneven skin tone.

You can find red algae in several Asian and Eastern European cuisine and are used as food additives like nori and dulse.


Green Algae: Chlorophyta



Now, this type of algae is known to be very diverse. They can live in seawater and freshwater habitats, and some even can be found on most soil. There are more than 4,000 species of green algae and come in three forms: unicellular, colonial, or multicellular. Green algae contain large amounts of Vitamin C and magnesium so it can help moisturize and clear up acne prone skin.

Highly nutritious sea vegetables like chlorella, wakame, and sea lettuce are made from green algae!

Brown Algae: Phaeophyta


The most common type of seaweed is brown algae. It can be found in saltwater and can live in mild and arctic climates. Kelp is the typical kind of brown algae that is usually consumed. It contains several minerals and vitamins like vitamin K, A, C, E, B12, niacin, iron, calcium, riboflavin, and high in omegas 3, 6 & 9. Hence, it’s fantastic for anti-aging as brown algae can help improve e skin tone, texture, firmness, and elasticity.

Extracts of brown algae from Jeju Island in Korea, where the WHEN REVIVIFYING Anti-Aging Skincare Line’s key ingredient Seanol® is derived from, has become well-known as a super-food since it is rich in bioactive compounds and derivatives including phlorotannins, peptides, carotenoids, and fucoidans. Quality of brown algae from Jeju Island appears to be high thanks to the unique ecology and clean environment of Jeju Island, a UNESCO World Natural Heritage Site.
