They say nature is the best medicine, and it’s no secret that it plays a vital role in various skincare formulas; think Aloe Vera, Argan Oil, and Bentonite Clay, all well-known skincare ingredients. Algae has an established reputation as a superfood, but can it also benefit your skin?
What is algae, actually?
The word algae brings to mind slimy green or brown plants washing up on the beach. Slimy they may be, but they’re also a good example of why we should never judge a book by its cover. LiveScience describes algae as a diverse group of aquatic organisms that can conduct photosynthesis. Certain algae are familiar to most people; for instance, seaweeds (such as kelp or phytoplankton), pond scum, or the algal blooms in damns. Yet, there are anything from 30,000 to over 1 million species.
Studies have indicated that algae, which is often used as an ingredient in Asian cuisine, may boost your immunity, lower blood pressure, and promote heart health. It is seen as a superfood in wellness circles, and this has led skincare brands to take a closer look.
What does algae do for the skin?
Algae isn’t a new beauty ingredient, as it has been featured in skincare products since the 1960s. More studies have been conducted on individual algae species to explore their capabilities further and Astaxanthin is a great example of this.
Astaxanthin, which is extracted from red microalgae found in Iceland, is thought to be 6,000 times stronger than vitamin C. This makes it one of the most potent antioxidants in the world.
What makes algae a great addition to your skincare routine is that all algae types are considered humectants. These are substances that attract water, making them extremely good at keeping skin moisturized and plump.
Most algae also contain a range of nutrients, vitamins, and minerals, including magnesium, zinc, vitamins A, B, C, and E, fatty acids, and lipids, and proteins. All these compounds contribute to moisturizing and protecting the skin barrier.
Know your algae
The most common algae used in skincare is macroalgae. These are multicellular organisms which are commonly known as seaweed.
I think often we forget that algae survive in harsh environments and are often forced to adapt. For example, during low tide, seaweed is exposed to the sun, which has forced the algae to produce UV screening abilities such as antioxidants. It makes sense to try incorporating some of those capabilities into skincare products.
There are four color groups of algae, each with different properties and skincare applications:
- Brown algae (for example, kelp) tends to be the most used type of algae in cosmetic applications. This is due to their high levels of antioxidants, which provide the best skin hydration and have been shown to increase skin elasticity.
- Red algae contain the highest number of carotenoids, which help smooth the appearance of fine lines and wrinkles. Red algae have also been shown to improve the skin’s UV protection.
- Blue algae, also known as spirulina, are rich in antioxidants and are an effective neutralizer of free radical environmental damage. This makes it an excellent morning application choice.
- Green algae have been shown to promote firm, smooth skin. Interestingly, it is often used as a thickening agent in skin care applications.
What skin types benefit most from using algae?
The good news is that algae is beneficial to all skin types.
Due to the wide range of biological benefits, skincare infused with algae is safe for even the most sensitive skin. I would suggest you check the formula for each product to see if anything within would react with your skin type. The best application would combine the different colors to maximize the benefits.
Five products I recommend:
- REN Everhydrate Marine Moisture-Replenish Cream: suitable for dry, dehydrated, dull skin types. This water-locking algae-activated cream is clinically proven to deliver up to 48-hour defense from dehydration.
- DERMALOGICA Circular Hydration Serum: for lasting hydration.

This powerful spot solution targets existing blemishes, helping to reduce their appearance through exfoliation. Natural extracts and a marine algae complex help to soothe treated areas and minimize the appearance of redness.

- LELIVE Seatox: an excellent mask for acne, uneven skin tone and texture.

Seatox includes algae, sea spaghetti, and chlorophyll. This gives your skin the reset it requires, treating acne in a flash while improving uneven skin tone and texture.
