- Non-comedogenic and dermatologically tested
- Visible results within 2-4 weeks
- Affordable K-beauty price point

- Lower acid concentration may not work for severe acne
- Small 50ml bottle size for daily use
- Initial purging period can last 2+ weeks
- Not suitable for very dry skin types

๐ฐ Budget-Friendly Alternatives (Dupes)
Same brand philosophy with gentle AHA/BHA combo. More of a toner format than serum. Lacks the high Centella concentration but excellent for beginners. Fungal acne safe!
Pure 2% BHA without the AHA/PHA combo. More potent for blackheads but lacks soothing botanicals. Better for targeted spot treatment than all-over use.
Gold standard BHA exfoliant with proven results. More expensive but larger bottle. Fragrance-free and fungal acne safe. Better for sensitive skin types.
Higher AHA concentration (8% vs trace amounts). More aggressive exfoliation. Good for stubborn texture issues. Missing the BHA pore-clearing benefits.

โ Frequently Asked Questions
Use with caution. This serum contains Salicylic Acid (BHA) at 50ppm, which is a very low concentration. While topical application of low-concentration salicylic acid is generally considered safe by many dermatologists, it's best to consult with your healthcare provider before using during pregnancy or breastfeeding. The AHAs (Citric Acid) and PHAs (Lactobionic Acid) are generally considered safe for topical use during pregnancy.
No, this serum is NOT fungal acne safe. It contains potential malassezia triggers. If you have fungal acne, consider the SOME BY MI Miracle Toner instead (which has 0 fungal acne triggers), or choose products from COSRX or Paula's Choice that are verified fungal acne safe.
Avoid using with Vitamin C, Retinol, or other strong acid products in the same routine to prevent irritation and over-exfoliation. If you want to use these actives, alternate them on different days or use them at different times (e.g., Vitamin C in AM, this serum in PM). Never layer multiple acids together.
This serum is best suited for oily, combination, and acne-prone skin types. The lightweight formula absorbs quickly without adding shine. It's also good for sensitive skin (with patch testing) due to its gentle acid concentrations and high percentage of soothing ingredients. Those with very dry skin may find it not hydrating enough and should pair with a richer moisturizer.
Most users notice smoother texture within 1-2 weeks. Reduced breakouts typically occur by weeks 2-4. The full "30 Day Miracle" results (faded acne marks, clearer skin, minimized pores) are usually visible after 4-8 weeks of consistent use. Note: Initial purging (temporary increase in breakouts) may occur in the first 1-2 weeks as skin adjusts.
Apply after cleansing and toning, before essences, ampoules, and moisturizer. The order is: Cleanser โ Toner โ THIS SERUM โ Essence/Ampoule โ Moisturizer โ Sunscreen (AM). Best used in your evening routine due to the acid content. Always apply SPF 30+ the morning after using.
No, this product has been clinically tested as non-comedogenic with a comedogenic rating of 1/5 (very low). It's specifically designed for acne-prone skin and contains pore-clearing BHA ingredients. However, everyone's skin is different - if you notice increased breakouts after the initial purging period (2+ weeks), it may not be suitable for your skin.
The serum has a PAO (Period After Opening) of 12 months. Once opened, use within one year for optimal effectiveness. Store in a cool, dry place away from direct sunlight. The 50ml bottle typically lasts 1-2 months with daily use (3-4 drops per application).
Verdict: The SOME BY MI AHA BHA PHA 30 Days Miracle Serum Light delivers on its promise as a gentler alternative to the cult-favorite original serum. With 89% calming botanicals and low-concentration acids, it's an excellent daily exfoliant for oily and acne-prone skin types who want results without irritation. The fast-absorbing, non-greasy formula is perfect for humid climates and those who found the original too heavy. While not suitable for fungal acne sufferers and those avoiding fragrance, this K-beauty staple offers impressive value with clinically-tested, non-comedogenic results. Best for: beginners to chemical exfoliation and those seeking a balanced approach to clearer skin.
Product Overview
Quick product notes are a great way to check if a product is free from commonly avoided ingredients by skincare enthusiasts. These preferences come about for different reasons depending on the ingredient such as personal experiences, sensitivities, health preferences & etc.
Just because a product is not free from a common preference does not mean it's a bad product! You can make a personal decision whether or not you want to use a product that contains these ingredients or not - click the labels of the preference to read more about them.
Quick Product Notes
Ever used a product that promised a certain effect but provided no results? It might not have contained any notable ingredients that could have been responsible for that promised effect. It doesn't matter what the marketing or packaging ยซpromisesยป it can do, if it doesn't contain anything that can help - then the likelihood of it helping is low.
We help you identify key notable ingredients that have been shown to help with effects such as acne-fighting, brightening, UV-protection, wound healing & anti-aging to help you achieve your skincare goals smarter. Please note that different notable ingredients have varying levels of research behind them, some are extremely well proven yet some have mixed research in their efficacy.
Just because a product doesn't contain any notable ingredients doesn't mean it's bad. And a product with notable ingredients (or even many) doesn't necessarily guarantee the efficacy of the product performing these effects either. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine this.
Be smart and use this as just a starting point for you to make more informed and smarter choices and compare it with reviews to see if the product is right for you
Notable Effects & Ingredients
Why are some products great for some people and horrible for others? Well everyone has different skin types and different reactions to the same ingredients.
We've identified a range of ingredients that are commonly regarded as potentially good or bad for those with Dry, Oily/Acne-Prone or Sensitive skin.
A product that contains good or bad ingredients for your skin type doesn't always flat out make the entire product good or bad for your skin. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine your skins reaction.
One of the best ways to use this section is to troubleshoot products you've had bad experiences with in the past. Check if it contains any of the marked ingredients to point out suspect ingredients to avoid in the future!
Ingredients Related to Skin Types
Ingredient Safety Breakdown refers to the percentage % of ingredients in different risk categories as classified by EWG (Environment Working Group) if they are available. There are almost endless cosmetic ingredients and they are one of the few organisations globally that have assigned ratings to a lot of the more commonly used ingredients which is why we reference them.
EWG is seen by many to be more on the alarmist side in their assignment of health ratings resulting in rating ingredients as riskier than they actually are. We recommend using this a reference point rather than a strict guide of ingredient safety and to always do further research if into ingredients that you may find suspect.
