Flourish Facial Cream officially launched this week, and I’ve been asked about the collagen stimulating peptide that we use.
First, it’s worth reminding ourselves what collagen is, and why it’s important.
Collagen (a strand is pictured above) is the most abundant protein in the body, and provides a scaffold or matrix for strength and structure. It gives our skin an impression of thickness. In the dermis, or the middle layer of skin, collagen helps form a fibrous network of cells called fibroblasts, upon which new cells can grow. It also plays a role in replacing and restoring dead skin cells. With age, our body produces less collagen. The structural integrity of the skin declines, and wrinkles form. Women experience a dramatic reduction in collagen synthesis post-menopause.
Environmental factors such as UV exposure, smoking, and a diet high in sugar are also thought to be factors that can deplete the level of collagen in our body.
Many skincare products are available with collagen as an added ingredient, claiming to replace the lost collagen. However, collagen molecules are too large to pass through the skin, so it is unlikely that these claims can be realised.
Our approach is to include a particular peptide which stimulates the skin’s ability to produce new collagen. A peptide is essentially a protein fragment, and we use a small peptide which was specifically developed to reduce any type of wrinkle, by stimulating collagen synthesis.
We always seek evidence when we are researching our ingredients. In a clinical trial of the peptide, objective improvements were measured in skin smoothness, and reduced wrinkle depth.
Generally, peptides are thought to work best when combined with other active ingredients. More on those in further blogs!
