Brand Overview

Peter Thomas Roth's Blue Marine Algae Intense Hydrating Mask comes with a slew of anti-aging claims that certainly sounds impressive. As it turns out, this mask has a mainly ho-hum list of ingredients and sub-par packaging—it just isn't a product we can get excited about.

Blue Marine Algae Intense Hydrating Mask is a fragrance-free, ice blue-colored gel that comes in a clear plastic jar with a screw-top lid. The packaging is the first of the dings against this product: It allows the delicate ingredients inside to be exposed to both light and air, meaning they'll start to lose their effectiveness as soon as it's opened (see More Info for all the details on why jar packaging isn't ideal for skincare products).

What about its blue color? That's not the result of the plant extracts included, rather, it's due to the inclusion of artificial blue dye. That isn't a bad thing (the dye isn't harmful to skin), but it's something to point out since the product's color is part of its name!

So what about Peter Thomas Roth's claims this provides "maximum anti-aging moisture" and the ability to create a protective "eco-bubble" over skin? Blue Marine Intense Hydrating Mask does include some good ingredients that have water-binding properties such as glycerin, pseudoalteromas ferment extract (a type of bacteria found in seawater), algae extract, and sodium hyaluronate. However, it lacks a more potent mix of antioxidants, vitamins, and moisturizing ingredients that would truly give it an anti-aging boost—and again, what antioxidants are included won't remain potent for long because of the jar packaging.

We should also point out that even though a big deal is made of the origins of some of its ingredients (marine algae from Arctic glacial ice and green tea from a specific island in Korea), those have nothing to do with how the ingredients perform; the descriptions just makes the product sound more exclusive and exotic.

Overall, because of its lack of more impressive anti-aging ingredients and its jar packaging, Peter Thomas Roth Blue Marine Intense Hydrating Facial Mask just isn't more than an average offering, especially considering its price. You'll find superior options on our list of Best Facial Masks.

Jar Packaging: The fact that it's packaged in a jar means the beneficial ingredients won't remain stable once it is opened. All plant extracts, almost all vitamins, antioxidants, and other state-of-the-art ingredients break down in the presence of air. Therefore, once a jar is opened and lets the air in, these important ingredients begin to deteriorate. Jars also are unsanitary because you're dipping your fingers into them with each use, adding bacteria that further deteriorate the beneficial ingredients.

The vast majority of ingredients that are most beneficial for your skin are not stable in the presence of light and air, which is exactly what happens when you take the lid off a jar (Pharmacology Review, 2013 & Journal of Biophotonics, 2010).

One of the critical factors in any anti-aging or skin-healing formula is the amount and variety of antioxidants, cell-communicating ingredients, and skin-repairing ingredients, and the more the better. These function in a variety of ways to reduce the effects of the constant environmental stresses your skin experiences (Dermatology Research and Practice, 2012 & The Journal of Pathology, 2007).

Once you open that jar you bought, you immediately compromise the stability of the anti-aging superstars it contains. (You can visualize their benefits disappearing like puffs of air each time you open up that lid!)

  • Contains some good water-binding ingredients.
  • Fragrance-free.
  • The ingredients included don't have the potent anti-aging benefits claimed.
  • Jar packaging means many of the mask's beneficial ingredients will start to lose their effectiveness once it's opened.

Peter Thomas Roth At-A-Glance

Peter Thomas Roth is a large but straightforward line with mostly uncomplicated formulations that, for the most part, are quite good and state-of-the-art. Unlike many product lines, most of the acne, AHA, BHA, sunscreen, and moisturizing products contain what they should to be effective and helpful for skin.

Even more impressive are the well-formulated cleansers, sunscreens, AHA products, and skin brighteners. The moisturizers have improved somewhat, and most are now packaged so that the light- and air-sensitive ingredients remain stable. In fact, Roth's packaging deserves special mention because it is exceptionally utilitarian.

After all that glowing praise, what you should be aware of are the instances of products containing potential irritants (noted in their respective reviews) as well as the products in jar packaging that contain ingredients which are sensitive to air and light.
