GIGARTINA STELLATA/KAPPAPHYCUS ALVAREZII EXTRACT

Description

Gigartina stellata/Kappaphycus alvarezii extract is a potent marine-derived ingredient widely used in skincare formulations. This extract is sourced from red algae species found in coastal waters worldwide. Rich in polysaccharides, particularly carrageenan, it offers significant hydrating and skin-conditioning properties.

The extract's high mineral content, including calcium, magnesium, and potassium, contributes to its skin-nourishing effects. It forms a protective film on the skin's surface, helping to lock in moisture and prevent transepidermal water loss. This action results in improved skin hydration and a smoother, more supple complexion.

Gigartina stellata/Kappaphycus alvarezii extract also exhibits antioxidant properties, helping to neutralize free radicals and protect the skin from environmental stressors. Its anti-inflammatory effects can help soothe irritated skin and reduce redness.

In skincare formulations, this extract is often used as a thickening agent and emulsion stabilizer. It's compatible with a wide range of other ingredients and suitable for various skin types, including sensitive skin. The extract is particularly beneficial in products designed for dry, dehydrated, or mature skin, where its moisturizing and protective properties can significantly improve skin texture and appearance.
