What is b-silk™ protein?

Our ingredient

Our first proprietary ingredient is a high molecular weight structural protein that complements the vital functions of your skin and reinforces its extracellular matrix (aka collagen and elastin).

How we make b-silk™ protein:

B-silk™ protein is engineered in our labs using a simple fermentation process in which the inputs are yeast, water, sugar, and salt. Our method is clean, sustainable and cruelty-free.

How we test b-silk™ protein

Clinically-tested efficacy lies at the heart of our process. We rely on quantitative measurements, expert grading, and customer surveys to develop our products and distill their benefits. In our first clinical trial, 33 women with a mixture of normal, dry, and combination skin tested products containing b-silk™ protein. Here are the results.

Elasticity

Firmness

Hydration

Texture

Lifting

How is b-silk™ protein unique?

Our difference

B-silk™ protein is whole, never processed

Currently, most silk proteins used in skincare are fragmented into smaller pieces using molecular hydrolysis. Hydrolyzed silk proteins are highly processed and degraded, which can compromise their valuable properties and effects.

The size of a protein is often measured in Daltons. B-silk™ protein is ~80,000 Daltons, while hydrolyzed silk can be less than 500 Daltons. That is two orders of magnitude (or 100 times) smaller.

Naturally inspired, not derived from animals

Most silk ingredients sold in skincare products are made from silkworm cocoon derivatives. B-silk™ protein was inspired by the amazing properties of spider silk, whose unique molecular makeup makes it stronger and stretchier than silkworm silk. It is produced in the lab, without any animal inputs, making it 100% animal-free.

B-silk™ protein is not hydrolyzed. Through rigorous testing, we came up with a formula that includes b-silk™ protein without compromising its molecular structure, delivering more benefits, for better results.

Silk 101
An introduction to the material that started it all.
The material
Silk fabric is well-known for its luxurious, soft, and lustrous qualities. Despite its lightweight feel, silk’s molecular structure makes it an incredibly strong and biocompatible material. This combination of soft, yet strong makes silk ideally suited for regenerating and rebuilding human tissues.
The molecule

On a molecular level, silk is a structural protein made up of a long chain of repeating amino acids. If you imagine that the silk protein is like a necklace, each amino acid is an individual bead. The unique pattern of amino acids and repeating segments (FYI, b-silk™ protein has 18 of these) gives silk proteins their amazing properties.

Silk proteins are similar to other structural proteins found in our skin—collagen and elastin. As we get older, collagen and elastin start to break down, causing visible aging.

We include high molecular weight silk proteins in our products to support and protect the natural structure of your skin

Develop. Evaluate. Test. Repeat.

OUR FORMULATION PROCESS

01. Every ingredient counts

We consider the risk profile of every ingredient to minimize potential for any negative impact or irritation.

02. Conduct industry-standard tests

We test all products according to FDA standards. We test for skin sensitivity and irritation potential using the Human Repeat Insult Patch test and microbial testing. We test for efficacy through clinical studies and large consumer panels.

03. Validate using 3rd party testing

To keep us honest and unbiased, we use a third party testing service to determine our benefits.

P.S. Our products are not, and will never be tested on animals. Ever.

OUR STANDARDS
We use only the most trusted ingredients for healthy humans and a healthy planet.
Proprietary ingredients:
B-silk™ protein is made through fermentation, using simple, clean, and renewable resources like sugar, water, yeast, and salt. We actively seek to limit and eliminate any petroleum inputs from our process.
Additional ingredients:

We make no compromises when it comes to what we can and cannot put in our formulations. Many skincare ingredients are controversial due to an insufficient amount of information being available. As a company, we are committed to conducting thorough research, performing our own tests and taking a realistic, evidence-based approach to our formulations, so you know Eighteen B is effective and safe.

We support our knowledge by consulting peer-reviewed studies, established ingredient databases (like the EWG Database), and other leading industry lists (Sephora and Whole Foods), to evaluate ingredient risk profiles and eliminate controversial ingredients.

We will never include any of these ingredients in our formulas:

  • Synthetic fragrance
  • Phthalates
  • Parabens
  • Petrolatum
  • Petrochemical distillates
  • Mineral oil
  • Animal by-products

Our future is your future too.

Our commitment

We want to deliver skincare products that are better for your skin and better for the planet in every way possible. We want to disrupt the status quo and help move the industry forward in product safety and sustainability.

Innovation:

Science and technology guide our innovation and product development process. We are inspired by the amazing properties of b-silk™ protein, not the latest fad in skincare. When we let the science guide us, the possibilities are endless.

Safety & Sustainability:

We pledge to perform a life cycle analysis (LCA) on our b-silk™ protein manufacturing process to improve our impacts on the planet. We will build-out a holistic program for evaluating our ingredient supply chains to ensure that we are using the cleanest, safest ingredients available. We pledge to work towards packaging our product in the most sustainable way possible.
