How it works

Synergy Effect BTX Mask 80g carries a full manufacturer ingredient list, built around a base of common Korean-formula humectants and conditioning agents rather than a single headline active. MAXCLINIC is a derma-cosmetic brand built around concentrated ampoule and shot-format treatments, and this treatment mask follows that formulation approach. It belongs to a treatment-mask step, used a few times a week in place of the regular moisturizer step, and its finish and feel are the point of the format rather than any one named ingredient. This is the Korean-market formula, the version sold on shelves in Korea rather than one reworked for a different market.

Key benefits

  • What it is: Synergy Effect BTX Mask 80g from MAXCLINIC, a Korean-market treatment mask.
  • Fits into the routine: belongs to a treatment-mask step, used a few times a week in place of the regular moisturizer step.
  • MAXCLINIC is a derma-cosmetic brand built around concentrated ampoule and shot-format treatments.
  • Original Korean Formula: the same version sold on shelves in Korea, not a US-shelf reformulation.
