Some by mi Aha

Some By Mi is a Korean skincare brand that launched the AHA BHA PHA 30 Days Miracle Toner as its signature product and built a full routine around it after its initial viral success. The "30 days" positioning refers to the brand's claim that consistent daily use for 30 days shows visible texture and clarity improvement. The underlying mechanism is the three-acid exfoliant system: AHA for surface-level cell turnover, BHA for inside the pore, and PHA for light resurfacing with less irritation than AHA. Tea tree and Centella asiatica extract appear across the line as calming and anti-inflammatory support ingredients.

AHA (alpha hydroxy acid, typically glycolic or lactic acid) dissolves the bonds between dead skin cells on the surface, accelerating cell turnover and improving texture and radiance. It works on the outermost skin layer and is not oil-soluble, so it primarily addresses surface congestion and dullness rather than clogged pores deeper down.

BHA (beta hydroxy acid, typically salicylic acid) is oil-soluble and penetrates into the pore lining, dissolving sebum and debris inside the follicle. It is the acid used most specifically for blackheads, clogged pores, and acne-prone skin. Salicylic acid also has mild anti-inflammatory properties, making it useful for active blemishes as well as prevention.

PHA (polyhydroxy acid, such as gluconolactone or lactobionic acid) is the gentlest of the three. Its larger molecular size means it does not penetrate as deeply as glycolic or salicylic acid, producing a lighter exfoliant action suitable for sensitive or barrier-compromised skin. It also has humectant properties, drawing moisture into the skin as it exfoliates.

The 30 Days Miracle Toner (150ml) is the entry point and most popular product in the line. It contains all three acids at low concentrations, positioned for daily use as a leave-on exfoliant toner rather than a strong peel. Apply to cleansed skin by patting with a cotton pad or pressing with palms; the three-acid mix provides a progressive exfoliation with each application. The toner also contains tea tree extract and centella, which help counteract any sensitivity the acids might trigger. Both the English-labeled and Korean-labeled (Aha Baja Paha) versions appear in this collection; the formula is the same.

The Serum (50ml) delivers the acid and calming complex in a higher-concentration leave-on format applied after the toner and before the cream. It is the step for targeting specific texture concerns or active breakouts. Apply 3-4 drops to the full face or dot on problem areas; allow it to absorb for 30 seconds before the cream.

The 30 Days Miracle Cream (60ml) is the occlusive final step in the core routine, sealing moisture and the preceding active layers. It contains the same acid and centella complex but at lower potency suitable for a leave-on moisturizer. A two-pack option on the cream (2 x 60g) is available in this collection for buyers who go through it quickly.

The 30 Days Miracle Cleansing Bar (95g) and the Acne Clear Foam (100ml) are both rinse-off cleansers that bring the AHA BHA PHA complex into the wash-off step. Because these are rinse-off products, the acid contact time is short - roughly 30-60 seconds - so they contribute mild daily exfoliation rather than a treatment-level effect. The cleansing bar produces a dense foam and is slightly more targeted at oily or acne-prone skin; the Acne Clear Foam is a pump cleanser suited for daily double-cleanse or morning wash. Using both a cleanser and the leave-on toner from the same line in one routine is optional; for sensitive skin, starting with just one acid step (the toner alone) before adding the acid cleanser is a more gradual introduction.

The AHA BHA PHA 30 Days Miracle Truecica Clear Pad (70 pads) is a pre-soaked exfoliant cotton pad. Each pad is saturated with the toner formula; you wipe across the face after cleansing instead of decanting toner onto a separate cotton pad. The convenience is the main advantage: the pads are pre-measured, disposable, and useful for travel or gym bags. 70 pads at one pad per day covers 70 days of use. "Truecica" references tiger grass (centella), which is added to the acid formula to buffer irritation. These pads are an alternative format to the bottle toner, not an addition to it - using both in the same routine doubles your acid exposure unnecessarily.

The 14 Days Super Miracle Spot Allkill Cream (30ml) is a targeted blemish treatment product. At 30ml it is sized for spot application rather than full-face coverage; apply a small amount to active blemishes or clogged-pore areas after toner and before the main cream. The "14 days" positioning suggests a faster action timeline than the main 30 Days routine, reflecting the higher active concentration in a spot cream versus a leave-on full-face cream. This product is listed as the old formulation on this page; check the label on arrival for the current formula.

A simple starting routine with this collection: cleanse with the Acne Clear Foam or Cleansing Bar, apply the 30 Days Miracle Toner, follow with the Serum on targeted areas or the full face, then seal with the Cream. Morning routines should include an SPF after the cream; acid-exfoliated skin is more photosensitive, and skipping sun protection undoes the barrier-improvement work. In the evening, the same sequence applies without SPF.

For first-time acid users, start with the toner alone for two weeks before adding the serum. If any stinging, peeling, or redness develops, reduce frequency to every other day rather than stopping entirely. Combining Some By Mi's AHA products with other brand acid products (e.g., additional glycolic toners or retinol) increases irritation risk; keep additional actives to separate evenings or remove them temporarily while establishing the Some By Mi routine.
