About this ingredient
Inositol is a sugar alcohol related to the B-vitamin group, found in human and plant cells. INCI: Inositol. In cosmetics it works as a humectant and conditioning agent: it holds water, softens skin, and supports stratum-corneum comfort. It is added to moisturizers, masks, and sensitive-skin products. Its standalone activity is mild: it is a supporting component, and claims of anti-aging or anti-stress action on skin lean on biochemical logic rather than clinical trials. 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.
