Methylsilanol Mannuronate is a compound of organic silicon with mannuronic acid, a sugar acid from brown algae. INCI: Methylsilanol Mannuronate. In a formula it works as a humectant and conditioning agent, marketed as a component for skin firmness and density. The silicon part and the sugar attract water, but topical clinical data on a marked firming effect are limited. It is a supporting humectant component rather than a lead active with a proven result. Pregnancy safety. Topical use, low systemic absorption, no evidence of harm. It can be used during pregnancy and lactation. Tolerance. Irritation and allergen potential are low, suitable for sensitive skin.
