Oilless Oil 100% Purified Squalane
Peter Thomas Roth makes much ado about their Oilless Oil 100% Purified Squalane, and while squalane has its benefits as a moisturizing agent, it is not more beneficial or unique than plain canola oil when it comes to the health of your skin. This is a good, basic fragrance-free option for adding moisture to your routine and is best for normal to dry skin.
Packaged in a clear container with a dropper applicator, Peter Thomas Roth derives their squalane from sugarcane. Squalane is a hydrogenated version of squalane, the latter being the pure component found in plants and animal sources. Squalene is rather unstable, however, and thus squalane is nearly all you'll find in cosmetics (the process of hydrogenation creates the stable squalane). It's important to note that all ingredients in cosmetics are purified, which includes squalane—thus, Peter Thomas Roth isn't doing something that other brands aren't.
Adding a few drops of this to a moisturizer or serum or applying it directly to skin is quite similar to doing the same with a facial oil (or plain oil, like avocado or argan, for example). As mentioned above, squalane is as basic as it gets for a moisturizing ingredient, but it does have some antioxidant properties that are, again, not much different from many non-fragrant plant oils.
Squalane isn't technically an "oil," but that differentiation is somewhat pedantic, because many emollients aren't technically oils, but still behave similarly when it comes to their effect on skin (like jojoba oil isn't technically an oil, for example, it's a liquid wax).
Ultimately, Oilless Oil 100% Purified Squalane is a fine option to add to your routine for extra moisture. This didn't earn our top rating like many facial oils relying on a single ingredient due to the fact that it is incredibly overpriced in comparison to its simplicity and alternatives available from other brands, like Acne.org Jojoba Oil or Physicians Formula Argan Wear Ultra-Nourishing Argan Oil.
Note: The non-comedogenic claim isn't accurate, as any ingredient or product can result in a breakout. More to the point, there are no standardized or universally accepted methods for testing comedogenicity—check the More Info section for more details.
- Squalane is a good moisturizing ingredient for dry skin (like any non-fragrant oil, i.e. olive oil or almond oil, etc.).
- No more special than any other ordinary plant oil, like those you would find in your kitchen cupboard.
- Overpriced for such a simple ingredient.
Under the conditions of this study, 100% pure concentrations of ingredients were layered five times per application over a period of two weeks, without cleansing the skin at any time. The manner in which these tests were conducted is not remotely similar to how we use skincare or makeup products—plus very few products are formulated with 100% of any one ingredient. What really determines whether an ingredient present in your skincare or makeup products is likely to trigger a breakout is how much of the ingredient is present in the formula and what else you apply as part of your skincare routine.
The researcher largely credited for developing the concept of comedogenic, Albert Kligman, said as much in his 1972 study, "Acne Cosmetica":
"It is not necessary to exclude constituents which might be comedogenic in a pure state. The concentration of such substances is exceedingly important. To exile such materials as lanolin, petroleum hydrocarbons, fatty alcohols, and vegetable oils from cosmetics would be irrational. What is ultimately important is the comedogenicity of the finished product (Archives of Dermatology, 1972)."
Last, the terms non-comedogenic and non-acnegenic are not regulated so they're not beholden to any agreed-upon standards. Any product, from the richest cream to the thinnest lotion, can use these claims and not have to prove they really don't clog pores or trigger acne breakouts.
Oilless Oil 100% Purified Squalane is for anyone looking for all the benefits of an oil without leaving an oily or greasy after feel. It is lightweight, clear, and odorless. Oilless Oil is derived from farmed naturally-sourced sustainable sugarcane (not from sharks or olives). NON-COMEDOGENIC will not cause breakouts.
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 lighteners. 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.
