Some By Mi AHA BHA PHA 30 Days Miracle Toner Review: Gentle Acids, Big Promises

Some By Mi AHA BHA PHA 30 Days Miracle Toner is a mild acid toner that suits oily and acne-prone skin looking for a light daily exfoliant. Its acids are low on the list and the brand gives a pH of 5.5, so expect gentle smoothing over time. It also contains peppermint oil and tea tree, so sensitive and very dry skin types have better options.

If you want to check how its ingredient list fits your own skin type, you can scan the bottle's barcode or label with the ingredient scanner in Pori.

Below we go through the full ingredient list, how strong the acids really are, who should buy it and who should skip it, the price per ounce, how to use it and what to buy instead. We compared published ingredient lists, brand claims and listed prices; we did not test these products on skin.

What is the Some By Mi Miracle Toner?

It's the best-known product from Some By Mi, a Korean brand whose "30 Days Miracle" line promises visible change in a month. Soko Glam, a US K-beauty retailer, describes it as a toner with three types of chemical exfoliants (AHAs, BHAs and PHAs) plus papaya and witch hazel extracts, a high concentration of tea tree water, and adenosine and niacinamide, and says it's dermatologically tested for sensitive skin with a pH of 5.5. The brand still sells it on its Korean store.

What's in it? The full ingredient list explained

Soko Glam lists: water, butylene glycol, dipropylene glycol, glycerin, niacinamide, Melaleuca alternifolia (tea tree) leaf water, polyglyceryl-4 caprate, Carica papaya (papaya) fruit extract, Lens esculenta (lentil) seed extract, Hamamelis virginiana (witch hazel) extract, Nelumbo nucifera (lotus) flower extract, swiftlet nest extract, sodium hyaluronate, fructan, allantoin, adenosine, hydroxyethyl urea, xylitol, salicylic acid, lactobionic acid, citric acid, sodium citrate, 1,2-hexanediol, benzyl glycol, ethylhexylglycerin, raspberry ketone, Mentha piperita (peppermint) oil. The same list appears on INKEEDecoder.

• Water, butylene glycol, dipropylene glycol and glycerin: a hydrating base.
• Niacinamide: fifth on the list, the most prominent active. Studies link it to lower sebum at 2% and fewer spots and less blotchiness at 5%, though this toner doesn't state its level.
• Tea tree leaf water: the water left after distilling tea tree leaves, milder than tea tree oil. A systematic review found the evidence for tea tree oil in acne still needs more and better trials.
• Polyglyceryl-4 caprate: a solubilizer that keeps the small amount of oil dispersed.
• Papaya, lentil, witch hazel and lotus extracts: plant extracts. Papaya carries the enzyme papain, but how much survives in a toner isn't stated.
• Swiftlet nest extract: an edible bird's nest extract popular in Asian skin care. It makes the toner not vegan.
• Sodium hyaluronate, fructan, hydroxyethyl urea and xylitol: humectants. Sodium hyaluronate is a form of hyaluronic acid.
• Allantoin and adenosine: a soother and a skin-conditioning ingredient used in anti-wrinkle products.
• Salicylic acid, lactobionic acid and citric acid: the BHA, PHA and AHA of the name, all in the bottom third of the list. Sodium citrate pairs with citric acid to buffer the pH.
• 1,2-hexanediol, benzyl glycol and ethylhexylglycerin: preservative-boosting solvents.
• Raspberry ketone and peppermint oil: the last two ingredients. INKEEDecoder classes both as perfuming. Peppermint oil gives a cooling tingle and can irritate sensitive skin.

A second version of the list on INKEEDecoder has tea tree leaf extract in place of leaf water and adds pentylene glycol, caprylyl glycol, ethyl hexanediol and phenoxyethanol. Both versions have been sold, so check the box you receive. There is no glycolic or lactic acid in either list; the AHA is citric acid.

How strong are the acids?

Mild. Three things point that way. The acids sit below the plant extracts and humectants, so they are present in small amounts. The pH is 5.5, close to skin's own; acids exfoliate more at a lower pH. For comparison, the FDA's guidance for AHA cosmetics accepts a concentration of 10% or less and a pH of 3.5 or greater as safe for consumers, so this toner is far gentler than that ceiling. And citric acid often works as a pH adjuster here, with sodium citrate as its buffer.

The PHA has a friendly track record. Polyhydroxy acids such as lactobionic acid give effects similar to AHAs without the sensory irritation and add humectant benefits, according to a 2004 review written by researchers working on PHAs. Our guide to PHA for sensitive skin explains more.

Salicylic acid is the ingredient with the most relevance for clogged pores, because it's oil-soluble. A Cochrane review of salicylic acid, niacinamide and fruit acids for acne found that the quality of evidence was low or very low for most comparisons, so these ingredients are reasonable helpers; none is a proven acne treatment on its own. See AHA vs BHA and salicylic acid for blackheads for the basics.

Who is it for, and who should skip it?

It's a good fit if you:

• Have oily or combination skin with occasional clogged pores and want a gentle daily acid.
• Are new to exfoliating acids and want a mild start. Our exfoliating acids for beginners guide covers the options.
• Like a cooling, refreshing toner step.

Think twice if you:

• Have sensitive or rosacea-prone skin: peppermint oil and raspberry ketone are fragrance ingredients, and tea tree can irritate. Our guide to fragrance and essential oils explains why that matters.
• Have very dry or damaged skin: even mild acids can sting a damaged barrier. Repair first.
• Have moderate or severe acne: a toner won't control it. Adapalene, benzoyl peroxide or a dermatologist's plan will do more.
• Avoid animal-derived ingredients: the bird's nest extract rules it out.

The AAD advises that sensitive skin may sting or burn after exfoliating and to choose your method by skin type. It also suggests testing a new product on a quarter-sized area twice a day for 7 to 10 days first; our patch test guide shows how.

How much does it cost per ounce?

As of November 2026, Soko Glam lists the 150 ml (5.07 fl oz) bottle at $22.44, about $4.43 an ounce. Other K-beauty retailers and Amazon sellers stock it too, often at different prices; buy from an established retailer to lower the risk of counterfeits. That's mid-range for a Korean toner and cheaper per ounce than most serum-strength exfoliants, though you'll use more of a toner.

How do you use it?

Soko Glam's directions are to soak a cotton pad after cleansing, wipe it over the skin and tap to help absorption.

1. Start every other evening after cleansing. Increase to daily only if your skin stays calm.
2. Wipe it on with a cotton pad, avoiding the eye area and any broken skin.
3. Follow with a hydrating serum and moisturizer.
4. Use sunscreen every morning. The FDA recommends a sunburn alert on AHA products, advising sunscreen, protective clothing and limited sun while using them and for a week afterwards. Many Korean sunscreens use UV filters not approved by the FDA and are sold in the US as imports; our Korean sunscreen guide explains.

Don't stack it with a retinoid or a strong peel on the same night. Our guides to how often to exfoliate and ingredients not to mix help you plan.

Is it worth buying?

It's a reasonable buy for oily skin that wants a gentle, refreshing acid step and doesn't mind a minty tingle. It is not a miracle, and the "30 days" name oversells a formula with low-placed acids at pH 5.5. If clogged pores are your main concern, a fragrance-free 2% BHA will do more; if your skin is sensitive, a PHA or hydrating toner without peppermint is the safer choice.
