beplain Mung Bean Pore Tight-Up Serum

What is this product?

A 30 ml water based pore serum from beplain's mung bean line, registered in Korea as a functional cosmetic for brightening and wrinkle improvement. Its 31 printed ingredients run water, glycerin, dipropylene glycol, niacinamide, with mung bean extract at position 10, a menthol derivative cooling agent at 16, adenosine at 17, pomegranate flower extract at 21 and one peptide, acetyl hexapeptide-8, last. There is no oil, butter, wax or fatty alcohol anywhere in the list, no acid, no retinoid, no fragrance compound and no alcohol. The brand publishes seven tests with named institution, dates and panel sizes of 20 or 33, reporting pore, hydration, elasticity and skin cooling changes, but every headline figure is a maximum and no report is linked. Best suited to oily or dehydrated oily skin that wants a light pore step; needs an occlusive after it on dry skin, and the cooling agent is the thing reactive skin should weigh.

What makes it different?

A pore serum with no oil phase, no acid and no retinoid at all, which is a narrow build for the category, paired with a cooling agent that gives it an immediate sensory signature. Its test disclosure is the other separator: institution, dates and panel size are printed for all seven studies, while every result is given as a maximum and no report is published.
