The LHA in this product refers to lipo-hydroxy acid, a term La Roche-Posay made up to make the form of salicylic acid they use (capryloyl salicylic acid) seem more impressive than it is. The only research on this ingredient comes form L’Oreal, La Roche-Posay’s owner. Their single study showed that an LHA peel at 5–10% strength was as good as, but tolerated better than, a glycolic acid peel at a concentration range of 20–50%, which can be quite irritating, so the comparison doesn’t make sense; it’s like comparing apples to lettuce. The take-home message is this quote from the study: “there were no statistically significant differences between the two groups.” Clearly, not even L’Oreal believes there is much to be gained from going with LHA peels over AHA peels (Source: Journal of Cosmetic Dermatology, December 2008, pages 259–262).

Regardless, your skin has nothing to gain but much to lose if you apply this serum because it contains a skin-damaging amount of alcohol. Alcohol causes free-radical damage, dryness, and irritation. Interestingly, glycolic acid is the predominant exfoliant in this serum, again proving that L’Oreal doesn’t believe their LHA concept is the best thing going for obtaining smoother, younger looking skin.
LHA serum contains LHA, glycolic and salicylic acids to minimize fine lines and wrinkles, diminish acneic breakouts, extract impurities and smooth uneven texture. Ideal for use before and after a chemical treatment, LHA Serum encourages cell proliferation for an overall healthier tone and texture. Suitable for all skin types, except extremely sensitive.

Brand Overview

La Roche-Posay At-A-Glance

Strengths: A few good cleansers; anti-aging formulas tend to be stably packaged to get the most out of the air/light-sensitive ingredients; many fragrance-free options; a unique lip moisturizer; some praiseworthy specialty products.

Weaknesses: Some problematic, overly irritating exfoliants; several ho-hum moisturizers and sunscreens; ineffective skin-lighteners; disappointing toner.

L'Oreal-owned La Roche-Posay has a pharmaceutical lineage based in France, and the company speaks of their thermal spring water as the cornerstone of their commitment to dermatological skin care. Sound familiar? L'Oreal-owned Biotherm makes similar claims for the water in their products, yet their marketing niche is spas, while La Roche-Posay caters to doctors and consumers interested in effective, no-frills skin care. Regardless of the source of their water, or how many minerals there may be in it, or the other benefits they assert it has, water is water and skin can't tell the difference. Even if the water were somehow "special," it takes a lot more than water to create and maintain healthy skin. This is something La Roche-Posay is aware of, because they do offer a fairly broad range of products to address the various needs of skin.

Their thermal spring water is said to be a rich source of selenium. Selenium is a nonmetallic element that has potent antioxidant ability. However, almost all of the research surrounding its benefits pertains to dietary or supplemental consumption, not to topical application. According to the research, selenium is absorbed into skin and helpful when applied topically only when applied as l-selenomethionine (Source: Journal of Cosmetic Dermatology, July 2004, pages 149–155). It is unknown whether the water La Roche-Posay uses contains this form of selenium, but we wouldn't bank on it for a unique benefit.

For a dermatologist-oriented line like La Roche-Posay, most of the products are surprisingly devoid of state-of-the-art or other interesting ingredients. There are some standout products, such as those with retinol and stabilized vitamin C; however, most of them are one-note options that offer the help of their promoted ingredient but don't commingle it with anything else of value to skin. It's ironic that although there's not a jar package to be found in this line, most of the moisturizers lack light- or air-sensitive ingredients, so jar packaging actually wouldn't be a problem. In fact, most of the moisturizers are downright monotonous. For the money, these products will leave your skin wanting more.

If you steer your way to the well-formulated products La Roche-Posay offers, you will find some first-rate options. They're not as varied as what many other lines offer, but for a pragmatic, no-frills approach to serious skin care, they'll do just fine. In fact, among all of the L'Oreal-owned skin-care lines, La Roche-Posay comes closest to successfully competing with the best of the best. It's up to you to decide if "close" is good enough. However, if you need to avoid fragrance and a range of potentially irritating plant extracts prevalent in the products of many brands, this line may suit your skin to a T.

Note: La Roche-Posay is categorized as a brand that tests on animals because its products are sold in China. Although La Roche-Posay does not conduct animal testing for its products sold elsewhere, the Chinese government requires imported cosmetics be tested on animals, so foreign companies retailing there must comply. This requirement is why some brands state that they don’t test on animals “unless required by law.” Animal rights organizations consider cosmetic companies retailed in China to be brands that test on animals, and so does the Paula’s Choice Research Team.
