Collagen

Explained

Collagen is a big structural protein that your body uses to keep skin firm and bouncy. Despite the marketing, topically applied collagen doesn't "refill" the collagen in your skin.

The molecule is too big to pass through your skin barrier so intact Collagen physically can't get past the surface.

What it actually does in your skincare is work as a humectant and film-former: it binds water, lays down a light moisturizing film, and reduces water loss from the surface. This helps make skin feel smoother and temporarily plumper.

This ingredient has been found safe for use in cosmetics with clinical studies showing no irritation, sensitization, or phototoxicity. It's typically used at low concentrations (often a fraction of a percent up to a few percent).

Collagen will not increase sun sensitivity, but you should always wear sunscreen during the day.

Q01Following your recent investment, what are the next steps to scale the platform and expand its capabilities?

From an operational perspective, the immediate challenge is to scale production while maintaining consistent, reproducible outputs across multiple client programs. The next challenge will be expanding the range of assays and disease models we can support. For example, can we build models using muscle samples from patients in different regions of the world, including those with muscular dystrophy? I believe we can. Beyond that, the greater challenge is modeling more complex conditions such as motor neuron disease, where multiple biological systems interact. Recreating those disease environments in a meaningful and physiologically relevant way will be essential to deepening our understanding of those conditions.

Q02What is AHCC?

A Japanese firm, Amino Up Co., Ltd., produces a standardized extract of the mycelia of the cultured mushroom Lentinula edodes. AHCC has shown the ability to increase dendritic cell numbers in the blood, enhance virus elimination, increase influenza antibody titers post-vaccination, and reduce cancer recurrences after liver tumor resection. In the last case, its use was also associated with a reduction in cirrhosis odds compared to the group that did not take this agent. This prompted the current study, where AHCC was examined for its potential to prevent the progression of liver fibrosis by inhibiting hepatic stellate cell (HSC) activation.

Q03What does collagen do?

Collagen helps to give strength to various structures of the body and also protects structures like the skin by preventing absorption and spreading of pathogenic substances, environmental toxins, micro - organisms and cancerous cells. Collagen protein is the cement that holds everything together. Collagen is also present in all the smooth muscle tissues, blood vessels digestive tract, heart, gallbladder, kidneys and bladder holding the cells and tissues together. Collagen is even the major component of the hair and nails.
