Benefits / What It’s For
This serum is designed to help with:
-
Reducing visible blemishes, congestion, and breakouts.
-
Improving skin texture (making skin feel smoother) and reducing uneven tone.
-
Controlling excessive oil / shine, reducing the appearance of enlarged pores.
-
Supporting the skin barrier (helping reduce dryness, irritation) over time.
Usage Instructions
-
Use after cleansing the skin, before heavier serums / moisturizers.
-
Recommended usage is morning and/or evening.
-
Perform a patch test before first full‑face use, especially if your skin is sensitive.
-
Avoid combining with pure vitamin C (ascorbic acid) in the same routine (may reduce effectiveness or cause irritation).
-
Follow up with sunscreen during the day. Active/nutrient serums like this can make skin more sensitive to UV. (General skincare practice, and implied in product guides)

Limitations & What to Watch Out For
-
At 10% niacinamide, some people (especially with sensitive skin) may experience stinging, slight irritation, or purging at first. Start with less frequent use and then increase.
-
The presence of Zinc PCA helps, but it does not treat acne medically — serious acne should be treated under dermatologist guidance.
-
Avoid layering it directly with strong actives (strong acids, etc.) in the same regimen without caution.
-
Always use with sunscreen during daytime to protect from UV damage.
