If you keep seeing some by mi in skincare routines, it is the Korean line built around the AHA BHA PHA 30 Days Miracle toner and its cica, snail and retinol relatives. Here is the brand shelf, plus the exfoliating pads, toners and soothing cica picks I would put next to it.
SOME BY MI Explained: the Miracle Line and the Exfoliating and Cica Picks Beside It

The name SOME BY MI is a little sentence. A 2019 brand spotlight explains that "something" and "by a miracle" were combined with "mi," which means beauty in Korean. Once you know that, the whole catalog makes sense, because almost every product carries the word Miracle. The brand's own product pages describe the mission as sticking to the essentials of cosmetics, with safe and clean ingredients and proven efficacy. I would read that as a promise to keep formulas focused, and I think it shows.
The range I see people start with is the AHA BHA PHA 30 Days Miracle family, which that same piece lists as a cleansing bar, toner, serum and cream. The AHA BHA PHA 30 Days Miracle Toner has 2% niacinamide and is written for blemish-prone skin, and the Truecica Clear Pad is the same idea in 70 toner pads. The Miracle Serum is a centella ampoule with tea tree water extract. The Bye Bye Blackhead Green Tea Tox Bubble Cleanser uses 16 tea ingredients, including green tea, centella, bamboo tea and pine needles. Then the shelf branches out: Retinol Intense Reactivating Serum, V10 Hyal Air Fit Sunscreen SPF 50, Snail Truecica Miracle Repair Cream and Beta-Panthenol Repair Cream.
My test for the toner, since it carries three acid families: start every other night, and only go daily when your skin feels comfortable the next morning.

Exfoliating pads and toners to compare
The toner is the gateway, so the obvious question is what else does the same job. Glow Recipe Watermelon Glow PHA + BHA Toner uses 3% PHA and 2% BHA in a watermelon base. Paula's Choice Skin Perfecting 2% BHA Exfoliating Toner is a leave-on liquid with green tea, and Alpyn Beauty Pore Perfecting Liquid pairs 2% salicylic acid with borage and tremella mushroom.
The pads are more hands-on. Dr. Dennis Gross Alpha Beta Extra Strength Peel Pads are a two-step peel with glycolic, mandelic and salicylic acids, and Dr. Loretta Micro Peel Peptide Pads have 10% glycolic acid at a 3.5 pH. Eighth Day Resurfacing Tonic Pads are textured bamboo rounds with both physical and chemical exfoliation. Retrouve Skin Brilliance Priming Pads use fruit-derived AHAs and are designed for twice-weekly use, and epi.Logic Even Balance Toner is a cushiony water with azelaic and lactic acids.
Pairing tip: pick one exfoliating step for the evening and leave the morning for hydration and sunscreen.
What I would skip: using a pad and an acid toner in the same night. The Miracle Truecica Clear Pad already does the pad job, so it makes more sense to compare than to stack.

Cica, snail and niacinamide picks for calmer skin
Cica and snail are the soothing half of the Miracle story, and the brands here take different routes to calm. Dr. Jart+ Cicapair Sensitive Skin Serum is fragrance-free and pairs a cica complex with allantoin. Erborian Centella Red Serum has 2% Korean centella, and Eau Thermale Avène Cicalfate+ Restorative Protective Cream is a rich, non-greasy cream for skin that feels overworked. Hanyul Korean Artemisia Soothing Gel Cream combines artemisia, cica and vitamins B5 and B3 in a lightweight moisturizer.
For barrier support, AESTURA ATOBARRIER365 Cream is a rich ceramide cream with visible capsules that melt on application. innisfree Green Tea Hyaluronic Acid + Niacinamide Serum is a daily, quenching serum with encapsulated hyaluronic acid. Glow Recipe Watermelon Glow Niacinamide Dew Drops is a gel serum you can wear under makeup, and Dr. Barbara Sturm Better B Niacinamide Serum pairs vitamin B3 with marine plankton extract.
Pairing tip: serum on damp skin, then a cream over it, and the Miracle Repair Cream from the first row is a good bridge.
What I would skip: a rich cica cream over oily skin that already feels comfortable. A serum alone does the soothing job without the weight.

Keeping a Miracle routine gentle
Think of a Miracle routine as one active and one soother. Use the toner or pad a few nights a week, then follow with a cica or snail cream and sunscreen in the morning, such as the V10 Hyal Air Fit Sunscreen SPF 50. If you add the Retinol Intense Reactivating Serum, keep it away from the acid nights. Patch test new products, and give your skin a few weeks before you judge. The best some by mi routine I can imagine is short, boring and consistent. That is exactly what the brand's own words about sticking to the essentials ask for.
The Korean sunscreens, serums and masks I add next
If SOME BY MI is where you start with Korean skincare, this shelf covers the steps around it, and I would begin with sunscreen. innisfree Invisible Barrier is an SPF 47 serum with Jeju Green Tea, Beauty of Joseon Day Dew leaves zero white cast, and innisfree Daily UV Mineral is green-tinted to neutralize visible redness. Dr. Jart+ Every Sun Day is a matte physical sunscreen with zinc oxide and titanium dioxide, and Glow Recipe Dew Shield is a fluid SPF 30 with clean UV filters.
For serums, LANEIGE Water Bank uses blue hyaluronic acid, Torriden BALANCEFUL has a 5D CICA Complex with five types of centella, and AESTURA A-CICA365 is a lightweight serum with pH4.5CICA. Yepoda The Repair Hero is a peptide serum with niacinamide, and Hanyul Red Rice is lightweight with fermented red rice extract and ceramide. Sulwhasoo First Care leans on aged ginseng extract.
For the evening, Yepoda The Calm Balm is a cleansing balm with olive oil, Glow Recipe Watermelon Glow is a hydrogel mask with centella asiatica, and Biodance Bio Collagen Real Deep is a gel-type mask with low-molecular weight collagen.
What I would skip: three serums in one night. Pick one and let the sunscreen do the morning work.
