This pudding-textured body butter is indeed rich in the emollient squalane, as claimed, but the amounts of indigo and liquid silk are too low to support the "rich in" claim Tatcha makes on this product's page, so you're getting a fairly basic, overpriced body butter for dry skin.
Research has shown that indigo is a rich source of a type of antioxidant known as flavonoids. That's encouraging, but it's only one of many plant-based antioxidants for skin. Indigo is also notable for being able to improve signs of atopic dermatitis (eczema is a common example) when applied to skin (Sources: Phytomedicine, March 2014, pages 453–460; and Natural Product Research, ePublication, January 2014, pages 492–495).
It's a shame Tatcha didn't give indigo more prominence, but even if they had, the choice of jar packaging wouldn't have kept it stable and effective for long, as we explain in the More Info section.
As for "liquid silk," they're referring to the ingredient sericin, which is one of the two proteins that make up silk; the other is fibroin. Sericin is the minor portion (approx. 20–30%), which makes the "liquid silk" name a bit misleading. Still, sericin is a beneficial ingredient for skin due to its amino acid content and smoothing texture, and it does have some impressive research behind it (Source: Journal of Scientific & Industrial Research, volume 63, April 2004, pages 323–329).
Although this body butter contains some intriguing ingredients, it's disappointing that the formula contains more fragrance than antioxidants, silk, and anti-irritants. Fragrance isn't skincare; in fact, it's an all-too-frequent source of irritation, as we explain in More Info.
In the end, this body butter isn't one we can recommend highly, even if the price doesn't faze you.
- The core ingredients and pudding-like cream texture moisturize dry skin.
- Lingering, eucalyptus-like fragrance poses a risk of irritation.
- Contains far more fragrance than exciting ingredients to benefit skin.
- Jar packaging won't keep this product's most exciting ingredients stable once opened.
Jar Packaging: The fact that this product is packaged in a jar means the beneficial ingredients won't remain stable once it is opened. All plant extracts, vitamins, antioxidants, and most other state-of-the-art ingredients break down in the presence of air, so once a jar is opened and lets the air in, these important ingredients begin to deteriorate. Jars also present a hygiene issue because even if you wash your hands or use a spatula to remove the product, you're introducing bacteria, which cause further breakdown of key ingredients (Sources: Free Radical Biology and Medicine, September 2007, pages 818–829; Ageing Research Reviews, December 2007, pages 271–288; Dermatologic Therapy, September-October 2007, pages 314–321; International Journal of Pharmaceutics, June 12, 2005, pages 197–203; Pharmaceutical Development and Technology, January 2002, pages 1–32; International Society for Horticultural Science, www.actahort.org/members/showpdf?booknrarnr=778_5; and www.beautypackaging.com/articles/2007/03/airless-packaging.php).
Fragrance in Skincare Products: Daily use of products that contain a high amount of fragrance, whether the fragrant ingredients are synthetic or natural, causes chronic irritation that can damage healthy collagen production, lead to or worsen dryness, and impair your skin's ability to heal. Fragrance-free is the best way to go for all skin types. If fragrance in your skin-care products is important to you, it should be a very low amount to minimize the risk to your skin (Sources: Inflammation Research, December 2008, pages 558–563; Skin Pharmacology and Physiology, June 2008, pages 124–135, and November-December 2000, pages 358–371; Journal of Investigative Dermatology, April 2008, pages 15–19; Journal of Cosmetic Dermatology, March 2008, pages 78–82; Mechanisms of Ageing and Development, January 2007, pages 92–105; and British Journal of Dermatology, December 2005, pages S13–S22).
