Some By Mi AHA-BHA-PHA 30 Days Miracle is one of the best-known K-Beauty lines for acne-prone, combination and oily skin. Its idea is to combine gentle exfoliation, sebum balance, pore care and soothing ingredients in one routine — without aggressively “drying out” the skin.
Why did this line become so popular?
In acne-prone skin care, the same mistake is often made: the skin is cleansed too aggressively. As a result, it becomes dry, tight and sensitive, while breakouts do not always decrease. The Some By Mi 30 Days Miracle approach is different — it combines acids with soothing and hydrating ingredients to work on texture, pores and excess sebum in a gentler way.
At the centre of the line is a three-acid concept: AHA, BHA and PHA. They help remove dead skin cells, work on clogged pores and make the skin surface look smoother. But tea tree, centella, niacinamide and hyaluronic acid are just as important — ingredients that help maintain skin comfort.
- Pore care The BHA direction helps work with sebum build-up inside pores, which is why the line is often appreciated by oily and combination skin.
- Skin texture AHA and PHA help support gentler exfoliation, so the skin can look smoother and more even.
- Soothing care Centella and tea tree help balance active care, so the routine is not only about cleansing and exfoliation.
- Hydration Hyaluronic acid, glycerin, betaine and other hydrating ingredients help reduce the feeling of dryness.
What do AHA, BHA and PHA mean?
These abbreviations often appear in products for acne-prone skin, but they do not mean the same thing. Each acid type works slightly differently, so the combination may be useful when the skin is oily, uneven and prone to clogged pores at the same time.
Water-soluble acids that mostly work on the skin surface, dullness and the feeling of uneven texture.
An oil-soluble acid type often chosen for pore care, sebum balance and the appearance of comedones.
A gentler exfoliating direction that is often better tolerated by more sensitive and dehydrated skin.
Who is Some By Mi 30 Days Miracle suitable for?
This line fits best into a routine when the skin is oily, combination, has the appearance of enlarged pores, blackheads, closed comedones or occasional breakouts. It may also be useful when the skin tone looks uneven after breakouts or when the skin texture appears rough.
However, very dry, damaged or strongly irritated skin should not introduce an acid-based line too quickly. If the skin burns, flakes or feels weakened after active ingredients, it is better to restore the skin barrier first and only then carefully add acids.
- For oily skin If the skin quickly becomes shiny during the day and the pores look congested.
- For combination skin Especially for the T-zone, where sebum build-up and blackheads are more common.
- For acne-prone skin If the skin tends to develop breakouts, comedones and uneven texture.
- For sensitive skin It may be suitable with caution, but should be introduced gradually and without other strong actives on the same evening.
What should you not expect from the “30 days” name?
The name “30 Days Miracle” does not mean that everyone will have completely clear skin without acne after one month. Skin condition is influenced by hormones, stress, diet, sleep, medication, cosmetic tolerance and the state of the skin barrier. It is better to see this line as the idea of a consistent 30-day routine, not as a guaranteed result.
If breakouts are painful, deep, suddenly become worse or leave scars, cosmetics can only be a supportive step, not a replacement for dermatological treatment.
4-step routine: Some By Mi 30 Days Miracle products
The classic 30 Days Miracle routine consists of four steps: cleansing, toner, serum and cream. You do not have to introduce all of them on the same day — for sensitive skin, it is better to start with one or two products and observe how the skin reacts.
Some By Mi AHA-BHA-PHA 30 Days Miracle Cleansing Bar
A cleansing bar for acne-prone skin with acids, tea tree, argan oil and olive oil base. It is designed for facial cleansing and can also be used on other problem-prone areas, such as the back or neck.
This step helps remove daily impurities and prepare the skin for the next products. If your skin is dry or sensitive, watch whether it feels tight after washing.

An acid toner for acne-prone skin that combines AHA, BHA and PHA acids with tea tree, witch hazel, papaya, lotus and other extracts. It helps work with dead skin cells, clogged pores and sebum balance.
You can apply the toner with your palms or a cotton pad. Start with a few times per week if your skin is not used to acids.

Some By Mi AHA BHA PHA 30 Days Miracle Serum
A two-phase serum with centella, tea tree, niacinamide, plant extracts and an acid complex. It is intended as a more targeted step for acne-prone skin that needs support for texture, pores, the feeling of redness and post-breakout tone.
Shake the bottle before use so the two phases mix together. If your skin is sensitive, do not use it on the same evening as other strong peels or retinoids.

Some By Mi AHA BHA PHA 30 Days Miracle Cream
A lightweight cream for acne-prone skin with 3 types of acids, tea tree and a high concentration of centella extract. It helps complete the routine, gives the skin comfort and fits well into combination or oily skin care.
Use the cream as the final step in the evening or before SPF in the morning, if your skin tolerates it well during the day.
View productHow to introduce this line without overloading the skin?
Because the line contains acids and tea tree, it is better to introduce it gradually. This is especially important if the skin is sensitive, dehydrated or has not used AHA/BHA/PHA products before.
Most often, it is better to start with the toner or cream, not the entire line at once. This makes it easier to understand how the skin reacts.
If the skin is sensitive, it is better to use the toner and serum with acids in the evening routine 2–3 times per week at first.
Acne-prone skin needs moisture too. If the skin becomes dry, tight or flaky, reduce the frequency of acids and add a barrier-supporting cream.
Acids can make the skin more sensitive to the sun, so use sunscreen during the day, especially in spring and summer.
What can you combine with 30 Days Miracle?
To keep the routine balanced, do not add too many other active ingredients next to acids. It is better to choose simple hydrating and soothing care.
- Can be combined with: hyaluronic acid, panthenol, ceramides, centella, lightweight moisturising creams and SPF.
- Combine carefully with: retinol, strong acid peels, scrubs, benzoyl peroxide and intensive vitamin C products.
- If the skin becomes dry: reduce the frequency of acids and switch to a calming routine for a few days.
Cosmetics with AHA/BHA/PHA can help improve the appearance of acne-prone skin, but they are not a medical acne treatment. If you have painful under-the-skin breakouts, a sudden acne flare-up, scarring or long-lasting inflammation, it is best to consult a dermatologist.
- Do not start using all products every day at once if your skin is not used to acids.
- Do not use acid products on damaged, strongly irritated or sunburned skin.
- If burning, noticeable redness or strong peeling appears, reduce the frequency of use.
- Use SPF during the day, because acids and sun exposure are not a good combination without protection.
Mini set or full-size products?
If you do not yet know whether this line will suit your skin, a mini set or one product from the line can be a good start. The set helps you understand the full logic of the routine, while a separate toner or cream is a safer option if your skin is sensitive and you do not want to change your entire routine at once.
Some By Mi 30 Days Miracle Starter Edition
The Starter Edition set includes the cleansing bar, toner, serum and cream in mini formats. It is a convenient way to get to know the line before choosing full-size products.
Frequently asked questions about Some By Mi 30 Days Miracle
Does the line really help with acne in 30 days?
For many people, skin texture and oiliness may improve with regular care, but the result is individual. It is better to see “30 days” as a period of consistent routine, not as a guarantee of completely clear skin.
Can this line be used every day?
If the skin is used to acids and tolerates the products well, some steps can be used regularly. However, sensitive skin should start with 2–3 times per week and increase the frequency only if there is no dryness or irritation.
Is Some By Mi 30 Days Miracle suitable for dry skin?
Dry skin should be careful, because the line contains acids and tea tree. If the skin is dry, it is better to choose only one product from the line and combine it with a richer moisturising cream.
Can it be used together with retinol?
It is better not to combine acids and retinol on the same evening, especially for sensitive skin. Choose separate days: retinol on one evening, an AHA/BHA/PHA product on another.
Why does the skin start peeling after acids?
Mild dryness may be related to using acids too often or not introducing them gradually. Reduce the frequency of use, add hydrating care and SPF. Strong burning or irritation should not be ignored.
