This lightweight moisturizer does not contain any ingredients capable of clearing breakouts. The only ingredient that’s even related to this claim is willow bark extract. Willow bark contains salicin, a substance that, when taken orally, is converted by the digestive process into salicylic acid (beta hydroxy acid, a staple anti-acne ingredient). The biological processes of converting willow bark to salicylic acid and then into salicin is complex, requiring enzymes and other chemical reactions, and skin cannot do to willow bark what the digestive tract can.
Further, salicin, much like salicylic acid, is stable only under acidic conditions, and this product isn’t acidic. Adding to the limitations is that the amount of willow bark in this product is too small for it to be effective, even if it could be converted into salicylic acid.
Willow bark may indeed have some anti-inflammatory benefits for skin because, in its natural form, it appears to retain more of its aspirin-like composition, but there are lots of anti-inflammatory ingredients that can benefit skin; willow bark is hardly the only one. This product also contains other antioxidant extracts, which is helpful; unfortunately, however, it also contains fragrant oils, all of which are capable of causing irritation—the very kind of irritation that triggers the base of the pore to produce more oil, potentially leading to more breakouts.
A non-drying, non-irritating formula that clears breakouts, leaving behind only lightweight hydration and skin that is smoother and healthier. It controls oil and reduces irritation, while preventing blemish marks and brightening areas of damaged skin.

Hailing from Japan and distributed through Fancl International in California, Boscia has two unique selling points: first, the entire line of products is preservative-free; second, almost every product contains both the anti-irritant willow herb plus jojoba leaf, which supposedly has superior antioxidant properties. The company's belief is that preservatives do not make skin-care products more effective; rather, they simply extend the product's shelf life, sort of like Tupperware keeps food fresher, longer.
They also believe that preservatives are responsible for skin troubles such as rashes and breakouts, and so our skin is better off without them. This is an interesting philosophy, and, as is true for many marketing ploys, there is some truth and some fabrication in their assertions.
Although preservatives can be sensitizing, they usually are present in such minute amounts that most consumers do not experience any trouble, and their skin barely registers a flicker of recognition. In reality, only a few people ever react to any amount of a preservative. A report that examined preservative sensitization in the United Kingdom tested 10 common preservatives on almost 7,000 subjects. The results? Only 2% of the participants exhibited an allergic reaction, and that was under conditions of patch testing and using a pure concentration of the preservative. That reaction rate is amazingly low, and it’s important to note that the exposure in the study (extremely high given the pure concentration and use of the patch method) is quite different from the exposure you get from the minuscule amounts of preservatives present in cosmetic products, which are there to keep potentially harmful bacteria and organisms under control.
Similar results were seen in a Swiss study that examined preservative sensitization rates among almost 2,300 subjects over a period of one year (Source: Contact Dermatitis, September 2007, pages 165–168, and May 1994, pages 276–279). Clearly, as demonstrated by these studies, preservatives are not the source of skin problems that Boscia makes them out to be.
What Boscia doesn't acknowledge is the research showing that preservatives do make cosmetics better. An effective preservative system absolutely does safeguard the integrity of fragile or inherently unstable ingredients by minimizing the growth of bacteria and microbes, which definitely are detrimental to any cosmetic and to your skin. Cosmetics chemists worldwide consider preservatives an essential element in providing safe, stable products (as do cosmetics regulatory agencies throughout the world).
Surely the chemists behind Boscia's products must know that it is impossible to keep a skin-care product entirely free of bacteria and pathogens, even with preservatives. If they disputed this point, they wouldn't sell their products with a "use by" date or recommend that their customers use the entire product within six months of opening. Instead, they'd assert their superiority and let their customers know that their innovative and specialized practices alone are enough to keep their products free of contaminants.
It's also important to note that, technically, Boscia products are not entirely preservative-free. Some of the plant extracts they include (such as rosemary and lavender) have mild preservative properties due to their volatile chemical components. Even zinc oxide, which appears in a handful of Boscia products, has been shown to inhibit the growth of fungus when used in cosmetics products (Source: Preservatives in Cosmetics, 2nd Edition, Allured Publishing, Steinberg, 2006, page 105). We personally wouldn’t choose one of these ingredients to preserve a water-based skin-care product over tried-and-true synthetic preservatives (including the unfairly and foolishly maligned parabens), but then again, consumers considering Boscia will likely perceive their products as being more natural (and, therefore, safer) than those from other lines—when that isn't at all the truth.
Besides, if Boscia is so concerned about reducing skin reactions and with being a viable option for people with sensitive skin, why do several of their products contain known irritants? Peppermint, menthol, eucalyptus oil, clove oil, and pepper resin are a much greater cause of concern for your skin than any preservative system available. Yet Boscia doesn't bother to explain that. Instead, they position their entire line as soothing for every skin cell, when that absolutely is not true.
Turning to the two ingredients Boscia highlights in their products, willow herb and jojoba leaf, both are viable options with value for skin. Willow herb, while not unique to Boscia (we've been using it in some of my products for years) is indeed a potent anti-irritant (Source: Journal of Agricultural Food Chemistry, October 1999, pages 3954–3962). As for jojoba leaf, there is no published research documenting its antioxidant ability. Like most plant leaves, it likely has some amount of antioxidant potency, but given the number of antioxidants that have been studied for use on skin, why would you hang your hopes on jojoba leaf, with no research behind it? Luckily, Boscia includes other antioxidants, too, and most of them have at least some research proving they are reliable additions.
There are some bright spots in this Japanese line. Each of the sunscreens provides sufficient UVA protection, and they offer a mineral-based version suitable for sensitive skin. They have a couple of good cleansers, and a few of the moisturizers are impressive and worth the splurge. It's also a plus that almost every Boscia product comes in packaging that keeps the contents protected from light and air—not a jar to be found! Given that only a small number of consumers need to avoid products with preservatives, we wish this line offered a more complete range of products to meet the needs of those consumers. As is, you'll have to think of Boscia as a nice pair of shoes with elegant accessories, and shop elsewhere to complete the ensemble.
