It’s clean, it’s sustainable, and it really works
B- SILK™ PROTEIN is our very own proprietary ingredient, and we think it’s pretty incredible. It’s clean, it’s sustainable, and it really works. To find out how it works, we’ll need to get a little technical. Read on to nerd out!
B-SILK™ PROTEIN was inspired by the properties of spider silk but it was designed in a lab and manufactured using a fermentation process. This means our B-SILK™ PROTEIN is vegan and made using bio-based and renewable inputs.
Why were we inspired by spider silk? Spider silk has a unique molecular makeup that combines the power of collagen and elastin into one. This means our B-SILK™ PROTEIN is both strong and soft. Moreover, silk has been widely studied in the biomedical field as a material for tissue regeneration, showing that it is highly biocompatible. These are just some of the reasons why silk and skin are a match made in heaven.
You might be asking, isn’t silk already available in other skincare products? Silk proteins from silkworms are used in other skincare products, but they are usually fragmented into smaller pieces using a process called molecular hydrolysis. This process breaks down a bigger molecule (polymer) into many smaller molecules (monomers) by severing the bonds that hold monomers together. Hydrolyzed silk proteins are highly processed and degraded, which can compromise their valuable properties and effects.
B-SILK™ PROTEIN, on the other hand, is not hydrolyzed. Through rigorous testing, we came up with a formula that keeps the molecular structure intact. This means B-SILK™ PROTEIN passes the multifaceted benefits of silk onto your skin in a way that hydrolyzed silk cannot.
What’s in it for me?
Clinically-tested efficacy lies at the heart of our ethos at Eighteen B so we put B-SILK™ PROTEIN to the test. We ran a 33-person clinical trial (third-party and double blinded), made up of women with a mixture of normal, dry, and combination skin. Here are the results after four and eight weeks:

How does B-SILK™ PROTEIN work?
B-SILK™ PROTEIN works like an extension of your skin barrier creating a lightweight shield to defend your skin against environmental aggressors while locking in hydration and stabilizing active ingredients against your skin so they can work harder resulting in reduced fine lines, smoother texture and overall firmer skin.
We liken the barrier B-SILK™ PROTEIN creates on the skin to Wonder Woman’s invisible jet. Super defensive, incredibly powerful, but you can barely tell it’s there.

This is why we call B-SILK™ PROTEIN your skin barrier’s new best friend. Not only is it defending your skin, improving its firmness and elasticity, it is also clean, sustainable, and vegan. In short, there’s a lot to love.
