Medicube: Inside The K-Beauty Device Brand Everyone Is Suddenly Buying

In 1786 the Bologna physician Luigi Galvani touched a frog's nerves with a pair of scissors during an electrical storm and watched the muscle jump. He spent years on frogs after that, and in 1791 he published his conclusion that living tissue holds an electricity of its own. Britannica says he was the first to establish that bioelectric forces exist inside living tissue. Two centuries later, a small pink device on a bathroom counter is still a conversation between electricity and the body.

Medicube is the brand that put that conversation in front of everyone. It launched in 2016 under APR Corp, a Seoul company, and the story it tells is that clinic-level care should come home as the real thing, not a watered-down version. The first products were dermocosmetics, including the Collagen mask, Zero Pore Pads and the Red Line treatments, which the brand says sold well in Korean pharmacies. The device came later. The AGE-R Booster Pro launched in 2023 after about three years of work at the brand's Seoul research center, and a viral clip of Kylie Jenner using it turned a pharmacy label into a household name.

The trick is to walk in the way the brand did, through the pores. The Zero Pore Pad is a BHA and AHA toner pad, used two or three times a week according to the instructions, and it is still the clearest way in. Around it sit the Zero Pore Blackhead Deep Cleansing Oil, the Blackhead Mud Mask and the SA Clear Capsule Facial Deep Cleanser, plus the Zero Foam Cleanser for a simpler wash. The Red Succinic Acid Peeling Pad and the One Day Exosome Shot 2000 and 7500 are the concentrated extras, one step at a time.

Here is how I would choose from this line: by step, not by shade of pink. Every product here has a job, so decide whether you want a cleanser, a toner, a serum, a mask or something for the eyes, and buy one of those first.

The PDRN Pink line is built around polydeoxyribonucleotide, which the brand and retailers describe as salmon-derived and used to visibly firm and revitalize skin. The Niacinamide Whip Cleanser and Niacinamide Milky Toner open the routine, and I like that the line starts there rather than at a serum. The Peptide Serum is the middle of the routine, with the Peptide Eye Serum as its small sibling. The Collagen Capsule Cream closes it up, and the Collagen Volume Multi Balm is the extra layer for the days that call for it.

The masks and patches are where the line gets fun. The PDRN Pink Collagen Gel Mask is a weekend evening, and the Caffeine Collagen Eye Patch is the small extra for the eye area. A pairing I like: the eye patch on while the gel mask sets, so one sit-down covers your whole face.

What I would skip: the PDRN line if you avoid animal-derived ingredients, since the active comes from salmon. The brand's collagen and kojic lines are the ones to look at instead.

One rule for these two lines: pick the concern, not the packaging. Collagen is about texture and bounce, according to the brand's own framing, and the Kojic Acid Turmeric line is aimed at tone, which is a different problem.

On the collagen side, the Collagen Niacinamide Jelly Cream is the daily one, the Triple Collagen Cream is the second cream option, and the Triple Collagen Serum is the serum step. The Collagen Night Wrapping Mask is the overnight version, the thing you put on before bed and wash off in the morning. If skin feels dull and uneven rather than loose, look at the Kojic Acid Turmeric side: the Turmeric Pad and the Niacinamide Serum for the everyday steps, the Vita Capsule Cream as the cream, and the Night Wrapping Mask for the end of the week.

A pairing I like within one line: a serum, then its own cream. The two are built to work together, and mixing lines makes it hard to tell what is helping.

What I would skip: both night wrapping masks in the same week. Put one on, see how your skin feels in the morning, and let it be the only overnight mask you change that week.

A habit worth borrowing: never run the device on bare skin. The Booster Pro is built around electroporation, which the brand says opens temporary micro-channels so a serum can absorb better, and a serum is the point of the whole exercise.

The Booster Pro is the one that changed the company. A third-party magazine describes it as combining six technologies, from microcurrent and LED light to vibration and thermal RF, and calls it the top-selling skincare device in South Korea. The absorption figures quoted for it differ between the brand's own site and press coverage, so I read any specific percentage as a claim rather than a fact. The Booster Pro X2 is the follow-up, and the V-Roller Head is the attachment for spreading the same idea over more of the face.

The serums are the part I would actually study. The Deep Vita C Capsule Cream and Deep Vita C Pad are for brightening, the Azelaic Acid 16 Calming Serum is the one for a face that gets red, the TXA Niacinamide 15% Serum is for tone, and the Hyaluronic Multi Peptide Serum is the hydration-and-peptides option.

What I would skip: the device on skin that is sunburned, freshly peeled or already irritated. Read the manual first and ask a doctor if you have a medical implant or a skin condition.

I think medicube is at its best when you treat it as a pharmacy shelf that happens to have a gadget attached. Start with the Zero Pore Pad and one cleanser from the same group. Add the PDRN Pink Peptide Serum or the Triple Collagen Serum once your skin is calm, depending on whether you want firmness or brightening. Leave the Booster Pro until last, and use it with a serum from its own group. Galvani needed a frog and a thunderstorm. You need a pad, a serum and a quiet Tuesday night.
