This anti-acne product earns its stripes, containing an effective amount of the topical disinfectant benzoyl peroxide in a fragrance-free lotion formula that contains antioxidant vitamin E and a good anti-irritant to help reduce redness from blemishes. Although pricey (there are definitely cheaper options with great formulations), it should help clear breakouts without leaving skin dry or flaky.
The claims mention 0.4% micro-exfoliating LHA, which is listed as capryloyl salicylic acid. The only study on this ingredient's benefits comes from L'Oreal, the company that owns La Roche-Posay. Interestingly, their study had nothing to do with acne; rather, it compared the effects of relatively low concentrations of LHA with the effects of relatively high concentrations of AHAs (that is, the concentrations dermatologists or aestheticians use in performing AHA peels), not to the effects of AHAs at the concentrations found in skin-care products (talk about comparing apples to oranges!). There isn't any research proving LHA helps heal breakouts or somehow improves clogged pores.
If you decide to try this product (keeping in mind that companies such as Clearasil, Paula's Choice, and Clinique offer less expensive, equally effective options), it is best to use it with a well-formulated BHA exfoliant (the exfoliant is applied first).
- Medicated with gold standard anti-acne ingredient benzoyl peroxide.
- Lotion texture is easy to apply and reduces the chance of dryness.
- Contains an anti-irritant to reduce redness.
- LHA ingredient isn't proven effective for exfoliation or reducing acne.
We had to comment on this product's claim that it can dry out blemishes. A blemish or other acne-type breakout has nothing to do with skin being wet, and water is the only thing you can "dry up." Products that make breakouts dry up and flake may make them look smaller, but it also trades one unsightly problem for another, and it prolongs healing time. Luckily, this product isn't formulated with drying ingredients (although some may find any amount of benzoyl peroxide intolerable), but we need to let go of the concept that blemishes need to be "dried up"!
