Science
Mechanism of Action
The Inositol Hexaphosphate (IP6) component functions as a robust antioxidant, actively neutralizing reactive oxygen species to prevent oxidative damage and support DNA repair mechanisms. It has demonstrated the ability to protect skin cells from UVB-induced apoptosis, thereby increasing cell viability and survival. Furthermore, inositol derivatives can influence hormonal pathways, potentially decreasing total testosterone, which is beneficial for managing hyperandrogenism-related skin concerns like acne. The Pyrrolidone Carboxylic Acid (PCA) component is a vital Natural Moisturizing Factor (NMF), enhancing the skin's capacity to attract and retain water, ensuring optimal hydration and barrier function.

Key findings
- 01 Topical application of a 4% Inositol Hexaphosphate (InsP6) rich gel has been shown to be absorbed through human skin, with detectable levels excreted in urine, indicating bioavailability.
- 02 In laboratory studies, Inositol Hexaphosphate (IP6) at a concentration of 0.5 mM effectively protected human keratinocytes (HaCaT cells) from damage induced by UVB radiation, enhancing cell viability and survival.
- 03 A combination of myo- and D-chiro inositol in a 40:1 ratio has demonstrated potential in ameliorating acne and excessive facial hair, particularly in conditions related to Polycystic Ovarian Syndrome (PCOS), by improving insulin resistance and decreasing total testosterone.
- 04 Inositol is commonly incorporated into face and neck cosmetic formulations at concentrations reaching up to 4%.

The Formula
Formulation
Stability
Both Inositol (myo-inositol) and Inositol Hexaphosphate (IP6) exhibit inherent stability, with IP6 notably enhancing the stability of certain enzymes. The optimal pH range for Inositol is between 5 and 7. The combined Inositol Hexa-PCA is expected to maintain good water solubility and stability within a neutral to slightly acidic pH environment.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has affirmed the safety of Inositol, including its phosphorylated forms, in cosmetic applications at current use concentrations. While specific safety assessments for 'Inositol Hexa-PCA' as a combined ingredient are not available, its individual components (Inositol, phosphorylated inositols, PCA) are well-established as safe, with Inositol generally recognized as safe (GRAS) by the FDA for food and dietary supplement uses. The maximum reported concentration for Inositol in face and neck preparations is up to 4%.
