Brand Overview

Algenist’s AA Barrier Serum is a good option for restoring skin’s healthy appearance and defending it from the damage airborne pollutants trigger – but it has one caveat you’ll want to keep in mind.

Housed in an opaque bottle that protects its antioxidant ingredients from exposure to light and air, this serum has a lightweight, fluid texture that applies easily and absorbs quickly. There’s not a trace of a residue left behind, just smooth skin, meaning it works well both over and under other skin care ingredients.

One of the first things you’ll notice about this serum is the smell, which isn’t the result of added fragrance. Rather, it’s the natural scent of the ingredient phloretin, an apple wood-derived antioxidant with an initial smell similar to that of acetone, a common ingredient in nail polish remover. The scent dissipates very quickly and isn’t bad for skin, but it’s worth pointing out because it is very apparent when you first apply this serum.

Backing up the phloretin are several other antioxidants, among them alguronic acid (from algae) common in most Algenist products, as well as ergothioneine (from mushrooms), green tea-derived epigallocatechin gallate, and vitamin E. There’s also the skin brightening antioxidant niacinamide, but it’s towards the end of the ingredient list, so you’re not getting as much of it as this product’s claims imply.

The formula also contains two skin-replenishing peptides and numerous hydrating amino acids that support this product’s claims of fortifying skin’s barrier.

All in all, it’s a great serum that can perform as claimed – as long as you can get past the initial odor!

Pros:
  • Lightweight, fluid texture absorbs quickly.
  • Includes several antioxidant ingredients.
  • Contains skin-replenishing peptides and amino acids.
  • Packaged to protect is light- and air-sensitive ingredients.
  • Fragrance free.
Cons:
  • The natural smell of phloretin might be off-putting for some.

Tested on animals: Yes

This anti-oxidant rich, fortifying serum is formulated to help defend the skin barrier against pollutants and environmental aggressors. Formulated with the highest concentration of Alguronic Acid from algae, our benefit-boosting ingredient, this fortifying serum combines with nutrient-rich niacinamide (Vitamin B3) and an anti-oxidant power house: Phloretin (from apple wood) and Ergothioneine (from mushroom). Skin barrier is fortified to help improve the appearance of dullness, redness, discoloration, lines, and skin tone.

Algenist At-a-Glance

Strengths: Good facial cleanser and toner; select serums and moisturizers formulated with an impressive mix of anti-aging ingredients; Targeted Deep Wrinkle Minimizer really does make wrinkles less apparent.

Weaknesses: Expensive; the star ingredient (a modified form of algae) doesn't have reliable research to support its anti-aging efficacy; jar packaging; some of the moisturizers contain eucalyptus oil, which can be a potent irritant.

Algenist is a small range of skin care products sold at Sephora with a focus on anti-aging. Like several other cosmetics companies, Algenist has based their brand on a single ingredient, an ingredient they claim has superior benefits for skin and that, therefore, is worth the steep price tag. In this case, it was the "accidental" discovery of a substance found in algae. As the story goes, a group of biotechnology scientists were looking for ways to use something called microalgae as a renewable source of energy when they stumbled upon a compound known as alguronic acid. Their research revealed that alguronic acid is one of the compounds responsible for regenerating and protecting algae cells.

Figuring they were on to something, the company did further in vitro testing (although the details of their tests are not available) and, of course, found that alguronic acid had anti-aging benefits on skin, too. Aside from having no idea what their studies did or didn't really show, in vitro means this ingredient was examined in a petri dish, not directly on human skin. They did limited testing on human skin, but many key details of these "studies" are not available. Instead, we're asked to accept that their ingredient made a remarkable difference. At the time of this writing, there isn't a single published study attesting to the claims Algenist makes for alguronic acid, so you're taking an expensive leap of faith in buying these products! We should note, there are several forms of algae that are valuable when it comes to providing skin with anti-aging benefits - it's just that the research surrounding alguronic acid remains scant.

Whether the story about alguronic acid being the answer for your skin is true or not, it is critical to keep in mind that skin, and skin care, is far more complex than one allegedly miraculous ingredient. Think of it like your diet: As healthy as green tea is, if that's all you consumed, you'd soon be malnourished. Just like your diet should contain a healthy mix of nutritious foods, your skin (which is your body's largest organ) needs a wide array of helpful ingredients to become and remain smooth, healthy, and, yes, able to look and act younger.

To Algenist's credit, their products contain more than just alguronic acid. Most of them have a good blend of skin-repairing and antioxidant ingredients, although the ones they call out as key ingredients (such as apple stem cells) have no real published research proving their efficacy. Despite the fact that their products contain some tried-and-true anti-aging ingredients, Algenist makes the same mistakes as many other lines, such as using jar packaging (which won't keep any of the beneficial ingredients stable during use) and including fragrance or fragrant plant extracts to give the products an appealing scent. Fragrance isn't skin care and, in fact, more often than not, will cause irritation that hurts your skin's ability to look and act younger!

In the end, Algenist is not a must-have line, and it certainly isn't worth expanding your beauty budget to afford. There are some acceptable to impressive options for those who don't mind spending more than they need to for effective products, but you'll find a wider, often better range of options on our list of Best Anti-Aging/Anti-Wrinkle Products.

Note: Algenist lists the alguronic acid in their products as algae exopolysaccharides, which is the accepted cosmetic labeling name for alguronic acid.
