This lotion is a water free lotion to maximize the stability of glutathione. 1ml of the lotion is usually applied daily and provides 200mg of reduced glutathione. Being a water free lotion it can take a little longer to absorb than some creams and may leave an oily residue on your skin for a few minutes before being absorbed. Our formulation is non gritty and also contains Vit E and liposomes to aid absorption. One bottle should last 50 days at the recommended dose.
