The Some By Mi AC SOS Kit is a four-piece travel set built around one idea: hit congested, breakout-prone skin with a graded set of acids and a very large amount of tea tree. It is the cheapest honest way to find out whether the Some By Mi 30 Days Miracle range suits you before committing to full sizes.

Two things you should know before reading further. Some By Mi has sold out of this kit on its own Korean store and at least one European retailer now lists it as discontinued — what we have is stock, not a permanent line. And despite how it is often marketed, this is not a gentle set. The details are below.

Exactly What Is In the Box

Everything the Some By Mi AC SOS Kit contains, with real sizes:

Four minis, all Korean-made. This is the current packaging version:

Item	Size	What it does
Miracle Acne Clear Foam	30 ml	Cleanser. Carries the highest acid load in the kit, on a base of 15% centella asiatica.
Miracle Toner	30 ml	Tea tree leaf water at 10,000 ppm, with light acids.
Miracle Serum	10 ml	Centella at 14.77%, tea tree, and a very dilute AHA blend.
Miracle Cream	20 g	Centella at 70.78% — the barrier step.

Some By Mi refreshed the artwork in 2024. The contents and sizes did not change; only the box did. If you have seen an older-looking Some By Mi AC SOS Kit online, that is the same product in the previous packaging.

Not the Starter Kit — Know the Difference

The Some By Mi AC SOS Kit has a near-twin, and the names do not help:

Some By Mi sells two near-identical four-piece sets and the names do not help.

	AC SOS Kit (this one)	Starter Kit
Cleanser	Miracle Acne Clear Foam 30 ml	Cleansing Bar (25–30 g)
Toner	30 ml	30 ml
Serum	10 ml	10 ml
Cream	20 g	20 g

That is the whole difference: a foam instead of a bar. If you want the bar, you want the Starter Kit, not the Some By Mi AC SOS Kit.

You may also see a “30 Days Miracle Trial Kit” advertised. That is not an official Some By Mi product name — retailers use it as a loose alias, usually for the Starter Kit. Check the contents list, not the title.

The four items in the Some By Mi AC SOS Kit: Miracle Acne Clear Foam, Miracle Toner, Miracle Serum and Miracle Cream — All four items. The foam is the *Miracle Acne Clear Foam* — check the name if you are comparing kits.

The Acids, With Real Numbers

What is actually working in the Some By Mi AC SOS Kit, measured:

Korean labelling requires exact quantities for certain ingredients, which means the Some By Mi AC SOS Kit is unusually transparent. These are the published figures:

Acne Foam — salicylic acid 5,000 ppm (0.5%), gluconolactone 10 ppm, citric acid 10 ppm, plus tea tree leaf water and calamine.
Toner — tea tree leaf water 10,000 ppm (1%), salicylic acid 100 ppm, lactobionic acid 100 ppm, citric acid 500 ppm, with niacinamide high in the list.
Serum — centella asiatica extract 14.77%, tea tree leaf water 10,000 ppm. The AHAs here are measured in parts per billion, not parts per million — glycolic, lactic and malic at 3,150 ppb each. They are present, not potent.
Cream — centella asiatica extract 70.78%, tea tree leaf water 10,000 ppm, capryloyl salicylic acid 100 ppm, willow bark 1,000 ppm.

Read that honestly and the picture is clear. The 0.5% salicylic acid in the foam is the only meaningful acid in the Some By Mi AC SOS Kit. The “AHA BHA PHA” on the box is technically accurate and practically modest — the real work is being done by tea tree, centella and niacinamide. Some By Mi publishes no combined AHA/BHA/PHA percentage, and neither will we.

Two Things We Will Not Claim

Two claims made about the Some By Mi AC SOS Kit that we will not repeat:

1. We will not call it mild or suitable for sensitive skin. Several retailers do — one major marketplace sells it under the title “Mild Exfoliating Daily Skin Care Set”. Look at what is actually in the Some By Mi AC SOS Kit: peppermint oil in three of the four items, alcohol high in the serum’s ingredient list, and the declared European fragrance allergens limonene, citronellol and citral in the serum plus limonene in the cream. That is a well-formulated acne set. It is not a sensitive-skin set, and the cooling tingle people describe is peppermint, not acid.

2. We will not call it vegan. Some By Mi does not claim it is, and correctly so — the foam contains beeswax and the toner contains swiftlet nest extract, which is bird’s nest. You can check both against Some By Mi’s own Korean product page, which publishes the full declaration with quantities. If you are looking for a vegan routine, this is not it, and any listing that says otherwise has not read the label.

Neither of these makes the Some By Mi AC SOS Kit a bad product. They make it a product that should be sold accurately.

Who It Is For

Who the Some By Mi AC SOS Kit was built for, in the brand’s own words:

“AC” stands for acne care. Some By Mi’s own Korean copy calls it an emergency calming set for acne-prone skin, and the distributor lists it for oily and combination skin.

The Some By Mi AC SOS Kit suits you if you have oily or combination skin with active breakouts, you want to trial the 30 Days Miracle range before buying full sizes, or you travel and want a complete four-step routine in cabin-legal sizes.

Look elsewhere if you react to peppermint or to fragrance allergens, if you want a vegan routine, if your skin is dry or genuinely sensitive, or if you are expecting strong exfoliation — the acids here are gentle by design.

How to Use the Some By Mi AC SOS Kit

Some By Mi’s order is foam, toner, serum, cream.

Miracle Acne Clear Foam — lather with water, massage over damp skin, rinse thoroughly.
Miracle Toner — on a cotton pad, sweep along the direction of your skin texture.
Miracle Serum — a few drops on fingertips, press into the skin rather than rubbing.
Miracle Cream — the last step, pressed in until absorbed.

Two additions of our own, because Some By Mi does not provide them. Patch test the serum and the cream first — those are the two items carrying fragrance allergens. And wear sunscreen daily while using the Some By Mi AC SOS Kit; there is no sunburn alert on this set, but any routine containing salicylic acid deserves one.

How Often

How often to use the Some By Mi AC SOS Kit — and a gap in the brand’s own guidance:

Some By Mi publishes no frequency guidance, no AM/PM split and no minimum age for this kit. That is a real gap on a set whose cleanser carries 0.5% salicylic acid, and we would rather name it than paper over it.

What we would suggest: the foam once daily in the evening for the first week, moving to twice daily only if your skin is comfortable. Toner, serum and cream can be used morning and evening from the start — they are mild. If you already use another acid or a retinoid, alternate rather than stack.

Realistic Results

What the Some By Mi AC SOS Kit can reasonably deliver:

Timeframe	Reasonable expectation
First few days	Skin feels calmer and less oily by evening. Existing spots unchanged.
1–2 weeks	Fewer new breakouts. Redness around healing spots reduced.
3–4 weeks	Texture smoother, congestion reduced — if the minis last that long.

What the Some By Mi AC SOS Kit will not do: clear cystic or hormonal acne, fade established scarring, or deliver thirty days of anything at these sizes. Some By Mi publishes no timeframe claim for the kit, so the table above is our estimate rather than a brand promise.

How Long It Actually Lasts

The one thing people get wrong about the Some By Mi AC SOS Kit:

Worth being blunt about, because the name invites a wrong assumption. “30 Days Miracle” is the name of the product range, not a promise about how long the kit lasts.

At realistic usage, 30 ml of toner and 10 ml of serum give you roughly ten to fourteen days, not thirty. The 20 g cream will outlast them. Buy the Some By Mi AC SOS Kit as a proper two-week trial of the range, which is genuinely useful, rather than as a month of skincare, which it is not.

Authenticity and Storage

How to check the Some By Mi AC SOS Kit you receive:

Check the barcode: 8809647390527. The Korean statutory disclosure names the manufacturer and responsible seller as Peren Vel Inc. (주식회사 페렌벨), and the country of manufacture as South Korea.

Period after opening: 12 months, printed as 개봉 후 12개월 on the Korean label. Store the kit at room temperature, away from direct sunlight, and keep the caps on.

One honest note on availability: this kit is currently sold out on Some By Mi’s own Korean store and marked discontinued by at least one European stockist. We are selling from stock. If the range works for you, plan to move to full sizes rather than repurchasing the kit — browse our full acne and breakouts range for what to move on to.

Warnings and Precautions

Everything published for the Some By Mi AC SOS Kit, plus three cautions of our own:

Stop and consult a specialist if redness, swelling or itching occurs, including after sun exposure. This is Some By Mi’s own statutory wording.
Avoid use on broken or wounded skin.
Keep out of reach of children and away from direct sunlight.
Contains peppermint oil in the foam, toner and cream, and fragrance allergens in the serum and cream. Patch test if you react to either.
Wear sunscreen daily. Some By Mi does not instruct this for the kit; we do, because the foam contains salicylic acid.
Some By Mi publishes no minimum age and no pregnancy guidance for this kit. Ask a doctor if either applies to you.

Frequently Asked Questions

What buyers ask us about the Some By Mi AC SOS Kit:

Does the Some By Mi AC SOS Kit really last 30 days?
No. “30 Days Miracle” is the range name. At these sizes expect ten to fourteen days.

Is it the same as the Starter Kit?
No. The Starter Kit has a cleansing bar; this one has the Acne Foam. Everything else matches.

Is it good for sensitive skin?
We would not recommend it. Peppermint oil is in three of the four items and the serum carries fragrance allergens.

Is it vegan?
No. Beeswax in the foam, swiftlet nest extract in the toner.

How strong are the acids?
The foam is 0.5% salicylic acid. Everything else is measured in parts per million or billion. This is a gentle set, not a peel.

Can I use it with other actives?
Alternate rather than stack. Some By Mi gives no interaction guidance.

Why is it tingling?
Most likely the peppermint oil rather than the acids.

Is it discontinued?
It is sold out on Some By Mi’s Korean store and marked discontinued by one European retailer. We are selling from stock.

Should You Buy It?

The honest verdict on the Some By Mi AC SOS Kit:

Buy the Some By Mi AC SOS Kit if you have oily, breakout-prone skin and want a genuine two-week trial of the 30 Days Miracle range in one box, or you want a complete four-step routine for travel.

Skip it if you need vegan, you react to peppermint or fragrance, your skin is dry or sensitive, or you were expecting strong exfoliation.

What we like is the transparency — Korean labelling forces exact quantities, so you can see precisely what you are getting instead of guessing. What we do not like is how it gets marketed elsewhere: as mild, as sensitive-skin friendly, and as thirty days of product. It is none of those. It is a well-made acne trial set with real tea tree and real centella, and at that it is good value.
