Isntree TW-REAL BIFIDA Ampoule 50ml

A 50 ml ampoule built on bifida ferment, the fermented ingredient family that Korean skincare inherited from a food culture where fermentation is the default preservation method, from doenjang to kimchi. Isntree gives it a double remit: tone care and wrinkle care, which in Korean labelling are two distinct regulated functional categories rather than one vague promise.

Who it's for. Mature or tired-looking skin, the appearance of uneven tone, and skin working on the look of fine lines. Suitable as a daily ampoule under a cream.

How to use. After toner, press two or three drops over face and neck, morning and night, then follow with moisturizer. It layers under the eye cream from the same line if you use both.

Key active. Bifida ferment lysate, a fermented conditioning ingredient used in Korean formulation for a smoother, evener-looking surface.

Sourced in Seoul. This is the Korean domestic SKU, not a reformulated export version.
