De-Spot Skin Brightening Corrector
Peter Thomas Roth's addition to the growing crop of hydroquinone-free skin lighteners contains a small amount of ingredients with limited research about their ability to lighten dark spots and improve an uneven skin tone.
The only ingredient of note is niacinamide, which is present in a high enough concentration to potentially improve discolorations, but you can fine less expensive products with this B-vitamin ingredient. The other significant skin-lightening ingredient is the mineral ingredient zeolite. A single in vitro (petri dish) study indicates it has the potential to suppress excess melanin (skin pigment) production. However, at this time, it's a novel approach without published research supporting its efficacy on human skin (Source: Biological and Pharmaceutical Bulletin, January 2010, pages 72–76).
So, although this zeolite may have benefit, it would be far better to seek out skin-lightening products with proven ingredients, such as hydroquinone (still the gold standard), forms of vitamin C (this formula contains a tiny amount of a form of vitamin C, but not enough to impact dark spots), arbutin, azelaic acid, or kojic acid.
All of these have considerably more research than the zeolite, which makes it less compelling. On balance, this serum-like skin lightener contains some intriguing ingredients, but most of them are present in tiny amounts that belie this product's high price. Although this appears to be fragrance-free, it contains a small amount of fragrant plant extracts. The formula is suitable for normal to dry or oily skin, but its benefits for brown spots or uneven skin tone are mostly due to the niacinamide content, and again, you can find good concentrations of that ingredient for less money.
- Amount of niacinamide may have a positive impact on discolorations.
- Contains some helpful anti-aging ingredients, including sodium hyaluronate and lecithin.
- Lightweight, silky texture works well with other products such as moisturizers.
- Expensive, considering that the efficacy and amount of most of its skin-lightening ingredients is questionable.
- Contains more preservatives than helpful antioxidant plant extracts.
Hydroquinone-free proprietary formula helps dramatically reverse the appearance of dark spots & discoloration due to aging, sun damage, pregnancy mask, and post-acne discoloration.
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.
