During VLCD, you can only use personal care products that do not contain food oils. During the VLCD phase, your body is extremely sensitive and can absorb oils placed on the skin and metabolize them as fat. Your body has adapted itself to only allow for the 500 calories from the food you are eating, and it is possible that any oils placed on the skin can cause gains or stalls. You will find a list of oil-free personal care products in our HCG Diet Guide. Once the HCG is out of your system and you are in the Maintenance phase of the protocol, you are free to resume using your personal care products as usual.
