Science
Mechanism of Action
This extract primarily provides skin protection. As a humectant, it effectively draws atmospheric moisture into the stratum corneum and supports the Natural Moisturizing Factor (NMF). It contains essential mineral salts, trace elements such as magnesium and zinc, and various vitamins, which contribute to its anti-inflammatory effects. Furthermore, compounds like fucoidan may impart anti-aging and photoprotective benefits to the skin.

Stability
Laminaria species seaweed extracts demonstrate stability within an acidic pH range of 3.5 to 5.5. These extracts do not exhibit strong reactions with either acidic or alkaline substances. Research with a similar Laminaria japonica extract indicates it maintains the overall physicochemical characteristics of formulations, including pH, refractive index, and viscosity.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel noted "insufficient data" in a March 2019 safety assessment for Laminaria Cloustoni Extract (also known as Laminaria hyperborea) for cosmetic use. However, it's relevant to note that 'Kelp,' which encompasses Laminaria cloustoni, holds a Generally Recognized As Safe (GRAS) status from the U.S. FDA for oral consumption as a food additive, suggesting a low risk profile for ingestion.

Verdict
While Laminaria Cloustoni Extract shows promise with its hydrating, soothing, and protective potential across all skin types, its overall safety for cosmetic use is currently limited by insufficient data from the CIR Expert Panel.
