Gigartina Stellata Extract description

_Gigartina stellata_ extract is the extract of the thallus (plant body) of the alga, _Gigartina stellata_. The accepted scientific name for _Gigartina stellata_ is Mastocarpus stellatus; however, the former is the agreed-upon cosmetic ingredient name. Like most algae, _Gigartina stellata_ has antioxidant and moisture-binding (humectant) properties. It’s a red macroalgae rich in hydrating polysaccharides known as carrageenans that can help contribute to the viscosity (thickness) of a cosmetic formulation. Clinical studies have shown that when fractions of this algae are enriched via biotechnology it has a visible effect on skin’s firmness and tightness, making it an intriguing ingredient for first signs of sagging, such as along the jaw line. It does so by influencing key collagens and fibular proteins in skin, helping to review their supportive abilities which results in visible improvements to facial architecture, including a feeling of renewed firmness. In essence, topical application of this specialized algae performs housekeeping duties within skin’s uppermost layers, ensuring the elements that keep skin strong and resilient are in their proper places and organized so they can do their jobs as intended. Human clinical trials on skin explants and in vivo testing on people has shown this extract helps re-densify and visibly lift skin for a more youthful appearance and remarkably supple feel. Use levels of _Gigartina stellata_ extract in skin care is 1% when supplied in a water and glycol base. It has broad compatibility with other anti-aging and hydration-boosting ingredients and is not believed to be sensitizing.
