The humble sheet mask isn't so humble anymore. A microcurrent version from Franz Skincare, a Seoul-based company, uses a mild electric current to push its ingredients deeper into the skin than a normal sheet mask. "Imagine panning for gold," says cosmetic chemist Ni'Kita Wilson. "You put the dirt, clay, and rocks in the pan, and they just sit there — that’s a traditional sheet mask. Now shake the pan around, and you are going to move more dirt through that pan." That's the microcurrent mask, but instead of moving dirt through a pan it's moving hyaluronic acid and a ceramide through the uppermost layers of the skin. Franz’s Microcurrent Facial Dual Mask comes in three parts (and costs $50 for two sets): a classic sheet mask soaked in a serum, and a dry mask and booster vial that together produce the current. You might not feel anything when you use it, says Myounghoon Jang, CEO of Franz Skincare, but one 25-minute treatment left our faces dewy, hydrated, and ever-so-subtly buzzing.
Next up: imperceptible acne patches, made with "electrospinning" technology at Franz HQ. Applying an electric field to a polymer solution creates nano-size fibers, which are then used to form a thin, flexible film. It is infused with skin-care ingredients and invisible under concealer — it's 20 times thinner than the average acne patch.
