I personally use it in the morning and evening. I massage for 5-7 minutes before getting dressed in the morning and before going to bed at night, but it takes longer at night.
I used slimming first, and put the slightly thicker one at the back. But I only use slimming lotion in the morning and two at night.
Dose. . . I just apply the same amount of body lotion myself to lose weight and maintain my health.
