Ferment Radiance Serum gives buyers a brightening-led concept that does not have to feel harsh or overly corrective. Yeast/rice ferment filtrate and Lactobacillus ferment form the center of the brief, while Damask rose water and a wide botanical profile help the product sit naturally within daily radiance and comfort-focused ranges.
Two ferments, one quieter product story
The formula information card pairs the ferments with portulaca, houttuynia, Chrysanthellum indicum, prickly pear, Stephania and gentiana. That combination gives brands room to build a more nuanced story around dull-looking, tired skin—one that brings hydration, botanical care and a fresh serum ritual together instead of relying on a single headline ingredient.
In use, the serum is applied in a small 3-4 drop dose after cleansing and followed with moisturizer. A dropper pack supports that controlled ritual and makes clarity, flow and absorption easy to review during sampling.
What buyers can decide before pack approval
BIO-TIDE can use the sample stage to align serum viscosity, formula appearance, botanical emphasis and dropper performance with the intended brand position. Final ingredient order, sensory language, packaging decoration and market-facing claims should follow the approved formula and destination-market review.
