Suits those who want a fresh clean-up with no irritation.
Applied to the skin it foams up, pushing debris and dead skin out of the pores to the surface. It uses a reaction in which the ingredient releases oxygen and swells, so it clears without any rubbing. Irritation is low, there is a cool sensation during the session, and calming and moisturising steps often follow.
It is done in four to five sessions at one to two week intervals. The skin feels fresher between immediately and two weeks, which is how long it takes for pore debris to clear and the surface to settle. The irritation is low, so a single session changes little and completing the course is better.
