SOME BY MI AHA BHA PHA 30 Days Miracle Toner

If you’re dealing with stubborn acne, clogged pores, and uneven texture, this toner is the miracle worker you’ve been searching for.
Its star ingredient is a 10,000ppm complex of AHA, BHA, and PHA. Think of the BHA like a deep-cleaning vacuum that goes into your pores to dissolve gunk, while the AHAs act like a gentle polisher on the surface to smooth away dead skin. This one-two punch is why many users see a noticeable reduction in breakouts and blackheads within the first few weeks.
Despite its power, the formula is surprisingly gentle enough for daily use. It’s packed with soothing ingredients like tea tree oil and snail mucin to calm irritation and prevent redness. This careful balancing act between effective exfoliation and skin-soothing care makes it a standout in the crowded world of acid toners.
Pros:
- 🟢 Effectively reduces acne and blackheads
- 🟢 Gently exfoliates without major irritation
- 🟢 Improves overall skin texture and brightness
- 🟢 Great value for the large bottle size
Cons:
- 🔴 Can be slightly drying for some skin types
- 🔴 The tea tree scent might be strong for some
- 🔴 Requires consistent use to see the best results
My Honest Opinion:
This toner is absolutely worth the hype and the money for anyone struggling with acne-prone or congested skin. It’s a true workhorse that delivers visible results, making it an easy recommendation for those starting their K-beauty skincare journey.
COSRX Niacinamide 2% + BHA 4% Blackhead Exfoliant Toner

If you’re looking for a gentle yet effective exfoliating toner to tackle blackheads and enlarged pores without irritation, this COSRX toner is a perfect match.
This toner combines a 4% BHA complex with 2% Niacinamide. The BHA dives deep into your pores to dissolve the gunk that causes blackheads, while the Niacinamide works on the surface to control oil and minimize pore appearance. For example, using it after cleansing feels like a deep clean for your pores, helping to prevent those pesky blackheads from forming in the first place.
I really appreciate its gentle, water-like formula that doesn’t strip or dry out the skin. It’s also fragrance-free, which is a huge plus for sensitive skin types.

Pros:
- 🟢 Gently exfoliates and clears pores without irritation
- 🟢 Helps visibly reduce blackheads and control oil

My Honest Opinion:

COSRX AHA/BHA Treatment Toner

If you’re looking for a gentle yet effective daily toner to tackle texture and clogged pores, the COSRX AHA/BHA Treatment Toner is a perfect starting point.
Its key feature is a low concentration of AHA and BHA acids, which gently exfoliate without the harsh sting of stronger formulas. Think of it as a daily polish for your skin; it helps to slowly dissolve dead skin cells and clear out gunk from pores, leading to a smoother, more even complexion over time.
I also love that it’s incredibly lightweight and hydrating, unlike some acid toners that can feel drying. This makes it a fantastic, non-intimidating gateway into the world of chemical exfoliation, building up your skin’s tolerance while consistently delivering results.

- 🔴 Contains alcohol, which can be a concern for very sensitive skin
My Honest Opinion:
This toner is absolutely worth the money for anyone new to acids or with sensitive skin that needs a gentle touch. It’s a reliable workhorse that delivers on its promise of smoother, clearer skin, as long as you’re patient and consistent with it.
Medicube Zero Pore Pads 2.0

If you’re looking for an easy way to tackle blackheads and texture without a complicated routine, the Medicube Zero Pore Pads 2.0 are practically made for you.
The star ingredient is PHA, a gentle exfoliant that clears out pores without irritating sensitive skin. Think of it like a tiny, soft sponge that sweeps away dead skin cells and gunk every time you swipe it across your face. This consistent, mild exfoliation helps prevent clogs before they even become visible blackheads.
I also love the two-sided design; one side is textured for light physical exfoliation, while the other is smooth for gentle toning. The pre-soaked pads are generously saturated with solution, so one jar lasts a surprisingly long time. It’s a no-fuss product that delivers visible results, making it a staple for maintaining smooth, clear skin.
Pros:
- 🟢 Gentle PHA formula is great for sensitive or reactive skin
- 🟢 Dual-textured pads offer both physical and chemical exfoliation

- 🟢 Extremely convenient and travel-friendly format
- 🟢 Pre-soaked pads are saturated with plenty of liquid
Cons:
- 🔴 The textured side can be a bit rough if you have very sensitive skin
- 🔴 The jar can dry out if not closed tightly after each use
- 🔴 Results are cumulative and require consistent use
My Honest Opinion:
This is absolutely worth the money for anyone seeking a beginner-friendly, low-commitment BHA/PHA alternative. It’s the perfect gateway product into the world of Korean chemical exfoliants for maintaining pore clarity with minimal effort.
SOME BY MI AHA BHA PHA 30 Days Miracle Cream

If you’re dealing with stubborn acne, enlarged pores, and uneven texture all at once, this miracle cream is your new best friend.
Its star ingredient is a complex of AHA, BHA, and PHA. Think of these acids as a dream team; the BHA dives deep into pores to dissolve gunk and blackheads, while the AHAs and PHAs work on the surface to gently exfoliate away dead skin, revealing a smoother, brighter complexion underneath without the usual irritation.
Despite being packed with powerful exfoliants, the cream itself has a lightweight, gel-type texture that absorbs quickly and doesn’t leave a sticky film.

- 🔴 Those with very sensitive skin may still find it a bit strong
My Honest Opinion:
This is absolutely worth the money if you have acne-prone or congested skin and want a powerful yet relatively gentle all-in-one solution. Just be patient through the initial purging phase, and you’ll likely be rewarded with much clearer, refined skin.
Buyer’s Guide: 3 Key Factors to Consider
Skin Type & Sensitivity
Your skin type dictates the BHA formula you should choose. If you have oily, resilient skin, you can handle stronger exfoliants like the COSRX Niacinamide 2% + BHA 4% Blackhead Exfoliant. For sensitive or dry skin, look for gentler, multi-acid blends that include soothing ingredients, like those found in the SOME BY MI AHA BHA PHA products.
Product Format & Ease of Use
Consider how the product fits into your routine. Toners are versatile and great for all-over treatment, while a cream like the SOME BY MI AHA BHA PHA 30 Days Miracle Cream is perfect for targeted application and added moisture. Pre-soaked pads, such as the Medicube Zero Pore Pads 2.0, offer maximum convenience and are ideal for travel or quick exfoliation.
Ingredient Synergy
Don’t just look at the BHA percentage. The most effective products combine BHA with other beneficial ingredients. Look for additions like Niacinamide (to control oil and minimize pores) or PHA (to gently hydrate and exfoliate). This synergy enhances the overall benefits and health of your skin.
Frequently Asked Questions
Q1: Can I use a Korean BHA product every day?
A1: It depends on the product’s strength and your skin’s tolerance. Gentle, multi-acid formulas like the SOME BY MI AHA BHA PHA 30 Days Miracle Toner are often designed for daily use. Stronger exfoliants, however, should be used 2-3 times per week. Always start slowly and monitor your skin’s response.
Q2: What’s the difference between the COSRX AHA/BHA Treatment Toner and the COSRX Niacinamide + BHA Toner?
A2: The COSRX AHA/BHA Treatment Toner is a mild, daily-use toner that preps skin for better absorption of subsequent products. The COSRX Niacinamide + BHA Toner is a more potent treatment toner specifically formulated with a higher BHA percentage to actively exfoliate inside pores and combat blackheads.
Q3: Should I use a BHA toner or a BHA cream?
A3: A BHA toner is typically used after cleansing to exfoliate and refine the skin’s surface. A BHA cream is applied later in your routine and is excellent for providing targeted treatment while also delivering moisture. You can use both, but not on the same night to avoid over-exfoliation.
Q4: Are these BHA products suitable for sensitive skin?
A4: Yes, but you must choose carefully. The SOME BY MI line, with its combination of AHA, BHA, and the gentler PHA, is often well-tolerated. The Medicube Zero Pore Pads are also a good option as they are physically gentle. Always patch test any new product behind your ear or on your jawline first.
Q5: How long does it take to see results with a Korean BHA?
A5: You may notice smoother skin and a brighter complexion within a few weeks. For more stubborn concerns like blackheads and enlarged pores, consistent use for 4-8 weeks is typically needed to see significant improvement as the BHA works to deeply clean and decongest pores.
Final Verdict: Which One Should You Buy?
Our top all-around pick is the COSRX Niacinamide 2% + BHA 4% Blackhead Exfoliant Toner for its potent, targeted action on blackheads and oily skin. For those with sensitive or acne-prone skin seeking a gentler, multi-tasking solution, the SOME BY MI AHA BHA PHA 30 Days Miracle Toner is exceptional. If you crave ultimate convenience, the Medicube Zero Pore Pads 2.0 are unbeatable, while the SOME BY MI AHA BHA PHA 30 Days Miracle Cream is the perfect choice for a hydrating, treatment-focused moisturizer.
