Product listings show two labeled options: a formulation for Normal skin and a formulation listed as suitable for All Skin Types. Check the specific product variant to confirm which option you are viewing.
Apply the ampoule after toner: dispense a few drops (or an ample amount), spread over desired areas, then gently pat to aid absorption. One listing also suggests prepping skin first with a 'First Essence 5X' for an extra boost before the ampoule.
The serums are described as lightweight and fast-absorbing, formulated to penetrate quickly without leaving a sticky or heavy residue and to layer well with other products.
The listings describe a multi-step process called an Extreme (triple) fermentation—warm/cold/other-stage fermentation—followed by a low-temperature, high-pressure extraction (referred to as a three-step Extreme Ferment method).
The product details list scents as Fresh and Unscented and note health facts such as Non-Toxic and Contains Probiotics.
