Fibroblast Protect

Fibroblast Protect at a glance

Fibroblast Protect is a marine appearance-focused cosmetic extract made from kombu, a brown seaweed of the kelp family harvested on the French coast. The seaweed is extracted with water, and the extract is carried in glycerin, which gives the INCI Glycerin, Water, Kombu Extract. The liquid is light brown to brown, dissolves in water and has a pH of 5.0 to 6.0. It is used at 1 to 5% of the finished product. Its name points to its role: fibroblasts are the cells in the skin that produce collagen and elastin.

Kombu as a cosmetic source

Kombu is well known in Japanese cooking, where it gives the savory umami taste to broths. That taste comes from glutamic acid, an amino acid that kombu contains in high amounts. Glutamic acid is also a building block of skin proteins and part of the skin's natural moisturizing factor. Together with the minerals and polysaccharides of the seaweed, this makes kombu a valuable base for skin care.

What it does

The supplier presents Fibroblast Protect as an extract that supports the skin's own renewing cells and their collagen production. In cosmetic terms, products with it help wrinkles look shorter and less deep, make the skin surface look smoother and more refined and give skin a firmer, more youthful look. The supplier also lists it for formulas with an antioxidant message. On the pack, keep claims visual and avoid cell level promises that cannot be seen.

How to formulate

Add the extract to the water phase of a gel or serum, or to an emulsion at cool-down below 40 °C. Its pH of 5.0 to 6.0 matches most face care, so no adjustment is usually needed. Use 1 to 3% in daily creams and up to 5% in intensive serums and lifting products. The light brown color can show in clear gels at higher levels. For an appearance-focused cosmetic serum, it combines well with hyaluronic acid and with a vitamin C derivative such as magnesium ascorbyl phosphate.
