AHA, BHA, PHA 30 Days Miracle Serum

Use with caution. This serum contains AHAs (glycolic, lactic acid) and BHA (from wintergreen extract) at low concentrations. While topical use of low-concentration AHAs is generally considered safe during pregnancy and breastfeeding, medical professionals recommend avoiding high-concentration acid treatments. The American College of Obstetricians and Gynecologists considers products with 2% or less salicylic acid acceptable. This serum has very low acid concentrations (ppb levels), but we always recommend consulting your healthcare provider before use during pregnancy or nursing.

No, this serum is NOT fungal acne safe. It contains multiple ingredients that can feed malassezia yeast, including: olive oil, caprylic/capric triglyceride, cetyl ethylhexanoate, and various seed oils. If you have fungal acne, consider the Some By Mi AHA BHA PHA 30 Days Miracle Toner instead, which is fungal acne safe, or look at alternatives like COSRX BHA Blackhead Power Liquid.

Use caution when combining with other actives. While this serum has gentle acid concentrations, layering multiple exfoliants can compromise your skin barrier. Avoid using with: strong retinoids (use on alternate nights), high-concentration vitamin C (use at different times of day), other AHA/BHA treatments (redundant and potentially irritating). You can use gentle vitamin C serums in the morning and this serum at night. Always introduce new combinations slowly and watch for signs of irritation.

This serum is best suited for oily, combination, and acne-prone skin types. The tea tree and BHA help control sebum, while centella soothes inflammation. It's also excellent for those with post-acne marks or uneven texture. Sensitive skin types can use it but should patch test first due to the alcohol content. Dry skin types may find it insufficient for moisture and should pair with a heavier moisturizer. Not recommended for those with fungal acne or extremely compromised skin barriers.

Despite the "30 Days Miracle" name, results vary by individual. Most users report: Week 1-2: Smoother texture, possible mild purging. Week 2-4: Reduced breakouts, less oiliness, cleaner pores. Week 4-8: Fading of post-acne marks, more even skin tone. 30+ days: Overall clearer, healthier-looking skin. Some users see immediate improvements in texture, while dark marks may take 2-3 months of consistent use to noticeably fade. Patience and consistency are key.

Apply this serum after cleansing and toning, before heavier serums and moisturizer. The routine order is: Cleanser → Toner → This Serum → Essence/Ampoule (optional) → Moisturizer → Sunscreen (AM only). Because it contains AHAs that increase sun sensitivity, it's best used in your PM routine. If using in AM, always apply SPF 30+ as the final step. Remember to shake well before each use to mix the bi-phase formula.

No, this serum has been clinically tested and proven non-comedogenic (rating: 2/5). Despite containing oils like olive oil and various seed oils, the overall formulation is designed not to clog pores. However, individual reactions vary. If you're very acne-prone or sensitive to certain oils, patch test first. The exfoliating acids actually help keep pores clear by removing dead skin cells that could otherwise cause congestion.

The serum has a PAO (Period After Opening) of 12 months. Once opened, use within one year for optimal efficacy. The 50ml bottle typically lasts 1.5-2 months with daily use (3-4 drops per application). Store in a cool, dry place away from direct sunlight. If the product changes color, smell, or texture significantly, discontinue use even if within the 12-month window.
