Some By Mi vs Medicube vs Neogen: The K-Beauty Exfoliator Showdown
A triple-acid toner, a dual-textured pore pad, and the original gauze peeling disc — three ways to fill the exfoliator step. Here's which one fits which skin, and how not to overdo it.

The "exfoliator" step of the 10-step routine is the one people fill a dozen different ways, and it's also the one most likely to wreck a barrier when you get it wrong. These are the three most-recommended K-beauty options, and they're not interchangeable — they exfoliate at different strengths and suit very different skin.
Full reviews: Some By Mi AHA BHA PHA Miracle Toner, Medicube Zero Pore Pad 2.0, and Neogen Bio-Peel Gauze Peeling Pad.

How to choose
Go with Some By Mi if congestion and rough texture are your main problem and your skin already tolerates acids. It's the highest actives load of the three — glycolic-family AHA for surface texture, salicylic acid (BHA) for clogged pores, PHA to soften the overall sting, plus niacinamide. It's a genuine treatment, not a daily-forever toner. See it on Amazon →
Go with Medicube if visible pores and blackheads on combination or oily skin are the concern, and you want a lower-commitment format than measuring out a liquid. The two-sided pad adds real physical exfoliation on top of a meaningful 4.5% AHA / 0.45% BHA dose. Acids make pores look less prominent by clearing what's in them — they don't shrink pore diameter, which is mostly genetic. See it on Amazon →
Go with Neogen if your skin is sensitive or reactive and a straight AHA/BHA product has burned you before. PHA molecules are larger, so they work more on the surface and irritate less — this pad won't out-exfoliate the other two, but it's the one you can safely use several times a week. The green tea and centella in the solution are doing real calming work, not just marketing. See it on Amazon →
The mistake all three punish
Stacking. If you're already using a leave-on retinoid or a separate acid serum, adding any of these on the same nights is how you over-exfoliate — tight, shiny, stinging skin that looks worse, not better. Pick one exfoliating step, watch your total weekly load, and follow every exfoliation night with a plain hydrating essence and moisturizer.
Our take
For the broadest set of people, Medicube Zero Pore Pad is the easy middle pick — effective dose, hard to overdo, and the format converts well from "I keep meaning to exfoliate" to actually doing it. Choose Some By Mi if you want more power and can handle it, Neogen if your skin needs the gentlest possible version of this step.
