This pudding-textured body butter doesn't contain enough indigo to support the "rich in" claim Tatcha makes, 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 (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 (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 soothing ingredients. Fragrance isn't skincare; in fact, it's an all-too-frequent source of skin aggravation, as we explain in More Info.
In the end, this body butter isn't one we can't recommend highly, even if the price doesn't faze you.
Why Fragrance is a Problem for Skin: Daily use of products that contain a high amount of fragrance, whether the fragrant ingredients are synthetic or natural, causes a chronic sensitizing reaction on skin.
This leads to all kinds of problems, including disruption of skin's healthy appearance, worsening dryness, redness, depletion of vital substances in skin's surface, and generally keeps skin from looking healthy, smooth, and hydrated. Fragrance free is always the best way to go for all skin types.
A surprising fact: Even though you can't always see the negative influence of using products that contain fragrance has on skin, the damage will still be taking place even if it's not evident on the surface. Research has demonstrated that you don't always need to see or feel the effects on your skin for your skin to be suffering. This negative impact and the visible damage may not become apparent for a long time.

Jar Packaging & Anti-Aging Moisturizers: This anti-aging formula is packaged in a jar, which means the beneficial ingredients won't remain stable for long once it's opened. All plant extracts, almost all vitamins, antioxidants, and other state-of-the-art ingredients are air-sensitive and begin to break down in the presence of air. Therefore, once a jar is opened and lets the air in, these important ingredients begin to deteriorate, becoming less and less effective.
Jars are also unsanitary because you're dipping your fingers into them with each use, contaminating the product. This leads to further deterioration of the beneficial ingredients.
When shopping for an anti-aging moisturizer, the ingredients that provide the most benefit for addressing visible signs of aging among many other concerns need to be in airtight or air-restrictive packaging.
