SOME BY MI AHA BHA PHA 30 Days Miracle Toner – 5.07oz, 150ml – Korean Refining Face Toner for All Skin Types – Daily Pore Care & Oil Control with 2% Niacinamide – Korean Skin Care

Why it's worth it

This Korean toner stacks AHA, BHA and PHA with 2% niacinamide, so it smooths the surface, clears out pores and dials back oil in a single step. It's the one to get if your skin is oily, rough and breaking out all at the same time.

Three acids cover three different depths. AHA loosens the dead cells sitting on the surface. BHA drops into the pore and dissolves the sebum plug. PHA has a larger molecule, so it works slowly and hydrates while it exfoliates, which makes it kind to a stressed barrier. Most toners pick one lane. This one runs all three, so it suits skin with both rough texture and visible blackheads.

The niacinamide is the quiet reason this works on pores. At 2%, niacinamide regulates oil output and calms the inflammation that makes a pore swell and gape. It isn't an exfoliant, so it works alongside the acids instead of piling more of the same onto your skin. If you were planning to layer a niacinamide serum over an acid toner anyway, this saves you a step and the waiting in between.
