Balancing & Clarifying Serum

Yes, this serum is considered safe for use during pregnancy and breastfeeding. It contains no retinoids, salicylic acid, hydroquinone, or other ingredients typically avoided during pregnancy. The formula relies on gentle amino acids, NAG, adenosine, and barrier-supporting ingredients that are safe for topical use. However, as DECIEM notes, their products haven't been specifically tested on pregnant individuals, so consult your healthcare provider if you have concerns.

Yes, this serum is fungal acne safe. It's oil-free and doesn't contain fatty acids, esters, or polysorbates that feed malassezia yeast. While it does contain Lactococcus Ferment Lysate, this is a lysate (broken down bacterial cells) rather than a live ferment, making it safe for fungal acne-prone skin. This is one of the few multi-active clarifying serums that's FA-safe.

Yes, this serum is compatible with most other actives including retinol, vitamin C, AHAs, and BHAs. The formula is gentle and doesn't contain direct acids, so it won't cause pH conflicts. Apply this serum first, allow it to absorb, then layer your other treatments. If using with strong actives like retinol or acids, start slowly and monitor your skin for sensitivity.

This serum is especially suited for oily and combination skin types dealing with excess shine, enlarged pores, and congestion. However, it's tested and suitable for all skin types. It's particularly beneficial for acne-prone skin due to its non-comedogenic, oil-free formula. Dry skin types can use it but should follow with a richer moisturizer. Sensitive skin should patch test first.

Clinical testing shows visibly clearer skin within 1 week of use. The full 7-benefit results (reduced pores, controlled oil, improved texture, faded post-acne marks, enhanced radiance, all-day hydration, and strengthened barrier) typically emerge by week 2. A 20% reduction in pore appearance was observed with continued use. Maximum results are seen with consistent use over 4-6 weeks.

Apply this serum after cleansing and toning, but before heavier serums, treatments, and moisturizers. The water-based formula should go on clean, slightly damp skin. Shake well before use, apply a few drops, and allow it to absorb before continuing with your routine. Use both morning and evening for best results. Follow with sunscreen during the day.

No, this serum has a comedogenic rating of 0/5. It's completely oil-free, silicone-free, and contains no heavy emollients or pore-clogging ingredients. The formula is specifically designed to reduce congestion and improve pore appearance, making it ideal for those prone to clogged pores and breakouts. The NAG ingredient actually helps clear existing congestion.

The serum has a PAO (Period After Opening) of 12 months. Store in a cool, dry place away from direct sunlight to maintain efficacy. The 30ml bottle typically lasts 2-3 months with twice-daily use (3-4 drops per application). Always shake well before use and ensure the dropper cap is properly sealed after each use.

At $19.90, this is one of The Ordinary's higher-priced products. The brand explains that the price reflects the seven different active technologies included in the formula, each targeting multiple signs of congested skin. While single-ingredient products like Niacinamide ($6.70) focus on 1-2 technologies, this multi-active approach offers a more comprehensive solution in one bottle.
