This moisturizer’s big claim is that its camu camu ingredient contains thirty times more vitamin C than an orange, as if that’s supposed to be a compelling reason to buy it. First, even if camu camu does have more vitamin C than an orange (more on that in a moment), so what? Kiwi has more vitamin C than an orange, too, as do papaya, bell peppers, and strawberries. The numbers game may seem impressive, but the formula would be more impressive if it contained a form of pure, stabilized vitamin C rather than a plant extract that contains the vitamin. Depending on how the plant extract was cultivated and stored prior to manufacture, who knows how much vitamin C would remain? Interestingly, a study sought to find that out and even under ideal storage conditions the vitamin C content of this fruit degrades over time (Source: Archivos Latinamericanos de Nutricion, December 2000, pages 405–408).
As for camu-camu, this shrub bears a fruit whose vitamin C content is higher in the peel than it is in the pulp (fruit) yet Peter Thomas Roth is using the fruit rather than the pulp, which is odd considering their boasts of camu camu being a superior source of vitamin C. The fruit, which has a strong sour taste, can be considered a skin irritant due to the volatile components it contains, including limonene (which can make skin more sun-sensitive) and eucalyptol (Source: www.naturaldatabase.com). Despite this, research has shown that components in camu camu juice can have antioxidant and anti-inflammatory benefit when consumed (Source: Journal of Cardiology, October 2008, pages 127–132).
Ultimately, this moisturizer (packaged in an airless jar to protect the light- and air-sensitive ingredients) contains a frustrating mix of beneficial and potentially problematic ingredients. It’s almost as though for every good antioxidant such as superoxide dismutase there’s a questionable fragrant one, such as ginger, lemon, and fennel, and that’s not a helpful way to give your skin the best of this important group of ingredients. Peter Thomas Roth added some good cell-communicating ingredients, too, plus repairing fatty acids, making this ideal for dry skin showing signs of aging—but again, the formula’s drawbacks (and price) should give you pause.
Powerful antioxidant camu camu, four potent antiaging peptides, intensive moisturizers, and vitamins A, D and E help improve collagen production, brighten, smooth, and firm the skin. Together, they improve the appearance of uneven skintone, fine lines, and wrinkles, deeply moisturize, and fight free radical attack, leaving a healthy, younger looking complexion.

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.
