Brand Overview

Peter Thomas Roth hits a home run with their Prostrength Niacinamide Discoloration Treatment 15% Brightening Complex, an innovative dark spot and dullness treatment for all skin types.

Packaged in a sleek, opaque squeeze tube that’s topped with a wider cap to keep it from tipping over (seems someone at the brand is just as annoyed with this as we are!), this dispenses as a white cream that feels silky and light, absorbing quickly whether you apply all over or just as a spot treatment to areas of concern.

Research supports the efficacy of the brightening ingredients this contains includings niacinamide, tranexamic acid (a newer topical whose results rival gold standard hydroquinone), kojic acid, white mulberry root, and resveratrol. All of these work on various pathways involving the creation and/or transport or dispersion of excess melanin in skin.

The brightening complex is claimed to be 15%, a claim we believe is accurate, although it would be better to know the specific percentages of ingredients niacinamide, tranexamic acid, and resveratrol, as these three have concentration minimums when the goal is improving dark spots, post-acne marks and areas of patchy discoloration. The amount of niacinamide is plenty to address dullness and uneven skin tone, and tranexamic acid needs to be used in at least a 3% concentration for best results, which seems to be the case here. It’s the other ingredients we’re not as confident about, but at least what precedes them is enough for visible improvement.

Despite this small letdown, we’re confident ongoing use of this treatment will produce visible results for most; however, as with any such treatment, daily use of a broad-spectrum sunscreen rated SPF 30 or greater is essential for best results.

The brand includes supporting antioxidant plant extracts like Scutellaria lateriflora, Hydrangea arborescens root as well as vitamin E (tocopheryl acetate) and emollient squalane, all kept stable in this product’s smart packaging.

We also appreciate the healthy glow this leaves behind due to the cream’s non-shimmering finish. It helps to instantly reverse a dull look, and Peter Thomas Roth omitted fragrance, score!

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.
