Can This Miracle Toner Really Transform Your Skin In 30 Days?

Last Updated on February 6, 2026 by Giorgia Guazzarotti

Some By Mi AHA BHA PHA 30 Days Miracle Toner has quickly achieved cult status. You can’t google Korean BHA toner without this baby topping every list. How the heck did it do it when… well, I’m getting ahead of myself. Suffice it to say, I’m NOT a big fan of this toner. Here’s all you need to know about it and why I DON’T recommend you add it to your skincare routine (popular doesn’t always mean good in skincare, FYI):

Key Ingredients In Some By Mi AHA BHA PHA 30 Days Miracle Toner

AHA + BHA + PHA TO EXFOLIATE SKIN

You’ll find three types of acids in skincare: Alpha Hydroxy Acids (AHAs), Beta Hydroxy Acid (BHA) and Polyhydroxy Acid (PHAs). Some By Mi AHA BHA PHA 30 Days Miracle Toner uses them all. Let’s start with what they have in common. They all dissolve the glue that holds skin cells together, so they can slough off and reveal the brighter and smoother skin underneath. But each family of acids has its own specific superpower:

• AHAs: They hydrate skin by drawing water from the environment into the skin. This toner uses citric acid, one of the gentlest members of this family.
• BHA: A.k.a. salicylic acid, it gets inside the pores, removing all the gunk that’s clogging them up and giving you pimples.
• PHA: They have antioxidant properties that help fight free radicals. This toner uses Lactobionic Acid.

The catch? Some By Mi AHA BHA PHA 30 Days Miracle Toner contains only a few drops of each acid. That’s why it takes 30 days to see some significant results. If you have sensitive skin that doesn’t tolerate high concentrations of acids well, this could be a good option for you to try.

NIACINAMIDE TO… WELL, EVERYTHING

A form of Vitamin B3, niacinamide is one of my fave ingredients. Why? It does everything you ask it to do:

• It hydrates skin: it’s more effective than petrolatum at preventing water loss
• It soothes skin: it alleviates the symptoms of rosacea and irritations
• It lightens skin: it reduces dark spots, blotchiness (redness) and sallowness (yellowing)
• It helps treat wrinkles: preliminary research shows it can boost the production of skin-firming collagen
• It treats acne: its effects are similar to those of 1% clindamycin gel

It doesn’t matter what your skin type is or what problems it has, it’s always a good idea to add some niacinamide to your skincare routine.

TEA TREE OIL TO TREAT ACNE

Derived from the Australian plant melaleuca alternifolia, Tea Tree Oil is a natural acne remedy. Tea Tree Oil is an antimicrobial agent that kills P.Acnes, the bacteria that causes acne. Plus, it reduces inflammation. Guess what acne is? An inflammatory disease.

The catch? All the studies I’ve found used 5% Tea Tree. Some By Mi AHA BHA PHA 30 Days Miracle Toner uses considerably less. Does that mean it’s useless? Not necessarily. But it does mean it works more slowly. Again, there’s a reason why it’s called “30 Days Miracle Toner” and not “3 Days Miracle Toner.”

The Rest Of The Formula & Ingredients

• Water: This is just the base. It’s not “hydrating” in any meaningful way on its own, it’s just what everything else is dissolved in so the formula can exist and spread on skin.
• Butylene Glycol: This helps the product sink in, feel smooth, and not dry out immediately. It also helps other ingredients actually get where they need to go.
• Dipropylene Glycol: It keeps plant extracts stable and evenly distributed so you’re not getting a weird uneven dose each time.
• Glycerin: This is the real hydration workhorse. It pulls water into the outer layers of your skin and helps keep the barrier from freaking out.
• Polyglyceryl-4 Caprate: This is a formula glue ingredient. It keeps oily components mixed into a watery product and helps with preservation. Y
• Carica Papaya (Papaya) Fruit Extract: This sounds exfoliating, but realistically it’s doing very little of that here. Any enzyme activity is mild and secondary.
• Lens Esculenta (Lentil) Seed Extract: This is usually included for oil-control and pore-appearance claims. The evidence is modest, and the effects are subtle.
• Hamamelis Virginiana (Witch Hazel) Extract: This tightens things up temporarily and can reduce surface oil. Some people love that effect, others find it drying or irritating. It’s a very polarizing ingredient depending on your skin type.
• Nelumbo Nucifera (Sacred Lotus) Flower Extract: This is mostly here as an antioxidant and calming plant extract.
• Swiftlet Nest Extract: This is more luxury storytelling than hard science. It contains sugars and amino acids that can hydrate superficially. There’s no strong evidence it outperforms cheaper humectants.
• Sodium Hyaluronate: This is hyaluronic acid’s more stable form. It helps hold water at the skin surface and gives that plump, hydrated feel.
• Fructan: A sugar-based humectant that supports hydration and barrier comfort.
• Allantoin: It helps soothe irritation and makes the formula more forgiving, especially with actives and fragrance around.
• Adenosine: This supports skin repair and has some evidence for wrinkle improvement over time.
• Hydroxyethyl Urea: This is a very effective humectant that also softens rough texture. It helps skin hold onto water better without the irritation risk of classic urea.
• Xylitol: Another hydration-support ingredient that helps strengthen the moisture network in the skin.
• Sodium Citrate: This works with citric acid to keep the pH steady.
• 1,2-Hexanediol: This helps preserve the product and adds a small hydration boost.
• Benzyl Glycol: Another preservative-support ingredient that also improves texture.
• Ethylhexylglycerin: This boosts preservation and adds a bit of skin conditioning.
• Raspberry Ketone: This is mostly here for scent and marketing appeal. There’s no good evidence it improves skin when applied topically. It can be mildly irritating for some people.
• Mentha Piperita (Peppermint) Oil: This is added for that cooling, tingly feeling and scent. It doesn’t actually calm skin long-term and can irritate sensitive or acne-prone skin.

Texture

The first thing you notice is how watery it is, like a really light essence rather than a thick toner. It’s thin enough to spread with your hands or a cotton pad and sinks in almost instantly without feeling sticky or slippery afterward.

Fragrance

There’s definitely a scent, but it’s not obnoxious: herbal and a bit green from the tea tree and peppermint oil in there, not full-on medicinal. It fades quickly once you pat it in, so it never lingers around like perfume. If you’re sensitive to strong smells, you’ll notice it, but it doesn’t make me flinch when I use it twice daily. Still, it can irritate sensitive skin.

How To Use It

I’d cleanse first, then either pour a few drops into my palms and gently press onto skin or swipe lightly with a cotton pad over my face. It’s one you don’t need to rub aggressively – just smooth and pat until absorbed. Because it’s got exfoliants, I didn’t do every single day at first, and when I did, I always followed with moisturizer and SPF in the daytime.

Packaging

The bottle’s simple plastic and the opening is easy to control so you don’t dump half the bottle in one go. It feels lightweight and travel-friendly. No fancy glass or luxe touches, but it’s sturdy and functional.

Performance & Personal Opinion

Don’t let the name fool you. Some By Mi AHA BHA PHA 30 Days Miracle Toner has such a small amount of exfoliating acids, it won’t sting or burn your skin, like Glossier Solution does. Phew! But that means it doesn’t really exfoliate. So what does it do?

After the first application, my skin already felt more hydrated. A week later, I started noticing an improvement in its texture. It felt smoother and looked a little brighter, too (it’s the power of hydration). Fast forward a couple of weeks and other people were complimenting me on it, too.

I don’t have any acne, so I can’t vouch for how well the tea tree oil works for that. But if I did, I’d probably keep my sulfur mask at hand to give this toner a helping hand. One more thing: this toner contains a few drops of peppermint oil, which can be irritating for sensitive skin. If you know your skin doesn’t like it, this isn’t for you.

What I Like About Some By Mi AHA BHA PHA 30 Days Miracle Toner

• My skin felt hydrated immediately after the first use
• Over a week or two, my skin texture smoothed out noticeably and looked a bit brighter
• Lightweight, watery formula that absorbs fast; no sticky or heavy feeling afterward.
• The packaging is simple but practical

What I DON’T Like About Some By Mi AHA BHA PHA 30 Days Miracle Toner

• The exfoliating acids are so low that it doesn’t really exfoliate
• Peppermint oil is present and can sting or irritate sensitive skin
• Tea tree oil is in there for acne, but if you have breakouts, you might need additional treatments for real effect.
• The toner doesn’t really do anything dramatic beyond hydration and minor smoothing

Who Should Use This?

• People looking for a hydrating, soothing daily toner rather than strong exfoliation.
• Anyone wanting a simple, lightweight toner to layer under serums and moisturizers for texture and brightness improvement.

The Verdict: Should You Buy It?

No. It’s marketed as an exfoliating miracle toner, but the acids are so weak it doesn’t actually exfoliate. Sure, it hydrates a bit and feels nice on skin, but if you bought it expecting real results, you’ll be disappointed. This one’s basically a hydrating toner in disguise, not a chemical exfoliant.
