Sake Hydrating and Brightening Essence
Sake Hydrating and Brightening Essence doesn't contain pure sake, but instead contains a fermented yeast that's derived from sake (rice wine). It's a good hydrating ingredient for all skin types, but the formula contains some seriously problematic ingredients making it impossible for us to recommend.
This is disappointing because Bosica includes several other hydrating ingredients, all in a texture that's easy to layer with other products.
The problem ingredients include menthol-derived cooling agent menthyl lactate, rosemary oil, and rose oil—OUCH! All of these pose a strong risk of irritation and diminish how your skin benefits from this product's good ingredients. See More Info for details.
Another issue: This essence is supposed to brighten skin, but lacks ingredients likely to produce noticeable results. Neither of the fermented ingredients in this product have research proving they can improve skin tone or dark spots. The licorice ingredient (dipotassium glycyrrhizate) and the beet root might help, but it really takes more than this to see a difference.
- Interesting mix of hydrating ingredients.
- Contains some plant-derived soothing agents.
- Texture is easy to layer with serum and moisturizer.
- Contains an irritating menthol derivative.
- Fragrant plant oils pose a strong risk of irritating skin.
- Lacks significant brightening ingredients, so is unlikely to improve skin tone.
Irritating Ingredients: We cannot stress this enough: Sensitizing, harsh, abrasive, or fragrant ingredients are bad for all skin types. Daily application of skincare products that contain these types of irritating ingredients is a major way we unknowingly do our skin a disservice!
Irritating ingredients are a problem because they can lead to visible problems that include redness, rough skin, dull skin, dryness, increased in oil production, clogged pores, and they contribute to making signs of aging worse.
Switching to non-irritating, gentle skincare products can make all the difference in the world. Non-irritating skincare products are those packed with beneficial ingredients that also replenish and soothe skin without any volatility, including those present in natural fragrant ingredients.
A surprising fact: Research has demonstrated that you don't always need to see or feel the effects on your skin for your skin to be suffering the impact and the visible damage may not become apparent for a long time. Therefore, don't get lulled into thinking that if you're not seeing signs of irritation, everything must be OK.
For this reason, it's best to eliminate, or minimize as much as possible, your exposure to ingredients that are known to irritate skin. There are many completely non-irritating products that contain effective ingredients, so there's no reason to put your skin at risk with products that include ingredients research has shown can be a problem.

An intensely hydrating gel-textured essence designed to deliver long-lasting moisture, soothing and reducing redness due to dry skin. Say cheers to this Sake-powered cocktail of essential hydration and brightness!
Strengths: All of the sunscreens provide sufficient UVA protection; the packaging not only keeps the plant-based and antioxidant ingredients stable but also helps minimize these preservative-free products' exposure to bacteria and organisms that can cause unhealthy changes; some good cleansers and moisturizers.
Weaknesses: Expensive considering the smaller-than-average sizes; several products are marred by the inclusion of irritating ingredients; no effective options for managing acne; only one poor option for lightening skin discolorations.
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 its 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 165168, and May 1994, pages 276279). 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 wouldnt 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 lineswhen 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 39543962). 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 airnot 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.
