It is done in three to four sessions at three to four week intervals. Tone and texture tidy up over four to eight weeks, because it works on the skin repairing itself and the response takes time to build. Keeping the interval lets each session settle before the next is added.

From around the second session tone is felt evening out, and it becomes clear over four to eight weeks. It does not break pigment directly — tone evens out as the skin recovers — so change comes gradually. In exchange the stimulus is mild enough for sensitive skin.

Its focus is regeneration and tone. Hydrating types feel plump at once but disappear as they are absorbed, whereas this evens out tone as the skin recovers, so the change lasts. The exact ingredients and blend differ by clinic, so confirm in advance.
