timeblock® 4 WEEKS is recommended as a primary course of treatment for over-nourish-ed, tired and stressed skin to help it regain its natural regenerative ability. Repeating the treatment at the start of spring/autumn pre-pares the skin perfectly for the challenges of the new season.
We also recommend using 4 WEEKS after long periods of travel, such as business trips, or after exposing your skin to the stressful effects of the elements, such as a beach or a skiing holiday.
