  2. The Initialization Stage – involves a series of preparatory steps aimed at priming the skin for the subsequent treatment. This may encompass deep cleansing, exfoliation, and gentle massage techniques, all of which serve to rebalance and revitalize the skin, laying the groundwork for optimal absorption of active ingredients.
  3. The Treatment Stage – targeted interventions are deployed to address specific concerns and optimize skin health. Drawing upon a rich repertoire of potent formulations, including the brand’s renowned range of serums, masks, and concentrates, the esthetician tailors each step to the unique needs of the individual’s skin.
