Why Some By Mi?
Some By Mi launched with a single, bold promise: visible skin transformation in 30 days. Their signature 30 Days Miracle line stacks three acid types (AHA, BHA, PHA) with calming botanicals to address acne, uneven texture, and hyperpigmentation simultaneously — without the irritation that usually comes with multi-acid formulas. Their approach combines Korean formulation precision with an accessible price point that made clinical-grade ingredients available to a wider audience than ever before.

AHA BHA PHA 30 Days Miracle Toner
AHA + BHA + PHA + Tea Tree 10,000 ppmThe triple-acid combination works across three depths simultaneously — AHA resurfaces, BHA decongests pores, and PHA provides gentle hydrating exfoliation — while 10,000 ppm tea tree extract keeps bacterial acne in check throughout the process.

AHA + BHA + PHA + Centella 4-Cica ComplexThis moisturizer pairs mild exfoliating acids with a 4-Cica complex to simultaneously turn over dead skin cells and rebuild the skin barrier, preventing the dryness that acid-heavy routines typically cause.

Salicylic Acid 5,000 ppm + PHA + Truecica5,000 ppm salicylic acid in a low-pH foam cleanser gives pores a medicated-strength deep clean without stripping, while 160,200 ppm Truecica immediately counters any inflammation the acids might trigger.

Snail Mucin 890,000 ppm + Truecica ComplexAt 890,000 ppm (89%), the snail secretion filtrate here delivers far denser mucin than most competitors; combined with cica's wound-healing triterpenes, this serum actively rebuilds compromised barriers and fades scarring.
