Background

CD19, also known as B-lymphocyte antigen CD19 or B-Lymphocyte Surface Antigen B4, is a 95 kDa type I transmembrane glycoprotein that belongs to the immunoglobulin superfamily and is encoded by the CD19 gene. It is primarily expressed on all B lineage cells, from early pro-B cells to plasma cells, and plays a crucial role in B cell development, activation, and signaling. As a co-receptor, CD19 enhances signaling through the B cell receptor (BCR) complex, lowering the threshold for B cell activation and promoting B cell proliferation and differentiation. It forms a complex with CD21, CD81, and other proteins, which helps in the recognition of antigens tagged with complement and amplifies BCR signaling. CD19 is also a biomarker for B cell-related diseases and a target for immunotherapies, including monoclonal antibodies and CAR-T cell therapies, due to its consistent expression on B cells and B cell malignancies.

Quality has gone way down from previous order
My first order was good but this last order had very little scent and had solid bits settled to one side and not distributed throughout the bar. I’m not sure if I want to continue buying this and I’m also concerned like everyone else that there’s no factual ingredient list.

Smells wonderful, but lacking a full ingredients list.
I have sensitivities in my household, and I've come to prefer products that have a full and transparent ingredients list. This soap does not offer one, only just the key ingredients featured on the outer packaging. Since I myself and some family members have to avoid certain ingredients in foods, drinks, and body products, transparency of ingredients means a lot to me. This soap has a delightful, soft, earthy scent that's clean and gentle, and not overwhelming. Don't let the patchouli throw you off- it doesn't smell like petrichor (wet dirt), it smells more of vanilla with powdery, earthy notes. It reminds me of the bags of vanilla flavored tobacco that my grandfather used to have around, and the scent is light, but long lasting on the skin. The soap bars are very soft, and oily to the touch when dry. I don't even need wet skin to get a lathering layer of this soap- I can rub it dry on my hands to get enough. I feel that if this bar were to exposed to water more frequently, it would quickly melt. The soap cleaves my skin feeling very fresh and clean, and isn't drying. I still prefer to use moisturizers, but my skin is dry in general. This soap does seem to help calm irritated skin and has not caused any irritation itself. I really like this soap, but I prefer to have full transparency of ingredients in my body products.

Best itchy soap.
This is has done more for my itching than about anything else. I was skeptical at first because "what works on both eczema and psoriasis?" But this is very effective. The instructions say "let dry out on skin for intensive treatment". I would NEVER let any ordinary soap do that. But this treatment truly works. It is excellent quality smells nice but scent is subtle and hypoallergenic. It is very emollient. Fair warning: you need to let it sit on your skin for a bit before you rinse it off. It kinda has to soak in before it rinses clean. And that's the other thing: you feel clean after using it instead of having gunky residue. If you have humid summer skin rash it even helps with that itch. It's very protective of your skin. If you want it to fit in a portable soap dish it fits a standard container if you cut it in half. It even does that well!
