Science
Mechanism of Action
Myristica fragrans powder exerts its effects on the skin through several mechanisms. It acts as an antioxidant by actively scavenging free radicals, thereby enhancing the activity and concentration of endogenous antioxidant enzymes such as catalase, superoxide dismutase, glutathione peroxidase, and glutathione reductase, which collectively reduce lipid peroxidation. Its anti-inflammatory properties are attributed to the potential inhibition of chemokines, cytokines, and nitric oxide, contributing to skin calming. The powder also demonstrates antimicrobial activity against various bacteria and fungi, aiding in the reduction of skin irritations and combating acne-causing bacteria. Furthermore, it functions as a skin conditioning agent, maintaining the skin in optimal condition, and may offer astringent qualities to assist in the constriction of skin pores. It can also contribute to a more uniform skin tone by reducing hyperpigmentation.

Safety Profile
Myristica fragrans Houtt. (Nutmeg) is classified by the FDA as 'Generally Recognized As Safe' (GRAS) for its use as a spice and natural flavoring in food. In cosmetic applications, it is listed in CosIng with 'FRAGRANCE' and 'MASKING' functions, without explicit SCCS opinions or restrictions for the powder form. However, myristicin and safrole, which are major components particularly prevalent in nutmeg essential oil, have been associated with potential hepatotoxicity and carcinogenic potential in rodents at high doses. For enhanced safety in cosmetic formulations, the use of degreased nutmeg is suggested to mitigate these potential risks.
