This facial oil from Boscia cannot prevent premature aging as claimed. No product should be making that claim unless it offers sun protection, which this doesn't. The numerous oils and emollient ingredients this contains can help dry skin look and feel softer, smoother, and, yes, younger, but the formula is far from perfect for dry skin or any other skin type. In fact, this is among the worst facial oils you could buy because it contains numerous fragrant plant oils research has shown are irritating to skin.

Chief among the problematic oils is lavender, which can cause cell death and oxidative damage (see More Info for details). This also contains orange, clove, and geranium oils, none of which are anti-aging or uniquely beneficial for skin. If the idea of a facial oil for dry or very dry skin appeals to you, go to the health food store and buy a couple small bottles of non-fragrant plant oil (like evening primrose and jojoba) to use alone or mixed with your moisturizer. Tsubaki Beauty Oil is a mistake owing to its potent fragrance.

Pros:
  • Contains several very good emollients and antioxidant-rich non-fragrant plant oils.
Cons:
  • Contains several fragrant plant oils, including lavender, which is among the worst for skin.
  • Doesn't prevent premature as claimed; only a sunscreen should be making that claim.
More Info:

Research indicates that components of lavender, specifically linalool, can be cytotoxic, which means that topical application causes skin-cell death (Source: Cell Proliferation, June 2004, pages 221–229). Lavender leaves contain camphor, which is a known skin irritant. Because the fragrance constituents in lavender oil oxidize when exposed to air, lavender oil is a pro-oxidant, and this enhanced oxidation increases its irritancy on skin (Source: Contact Dermatitis, September 2008, pages 143–150). Lavender oil is the most potent form, and even small amounts of it (0.25% or less) are problematic. Although it's fine as an aromatherapy agent for inhalation or relaxation, it is a must to avoid in skin-care products. (Sources: Psychiatry Research, February 2007, pages 89–96; and www.naturaldatabase.com).

Hydrates and replenishes, leaving skin smoother, softer and more supple. Helps prevent premature signs of aging by defending the skin against free radical damage.

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.

    boscia Animal Testing
    • boscia does not test on animals, nor have they ever tested on animals. This oil changed my life! It is the best out there. I thought this site was supposed to be "research-based"? I don't think this site does their "homework" very well.

    Hi, and thank you for your comments. There seems to be a bit of confusion here. We do not list Boscia as an animal tester here on the Paula's Choice website. Perhaps you're thinking of a different site?
