⚠️ Important (Real Talk):
- 15% niacinamide is high strength, so it may feel strong for beginners
- Some users report mild irritation, stinging, or redness if overused (common with high percentages)
- Works best when introduced slowly (2–3 times per week initially)
- Must use sunscreen daily for best results
- Not necessary for everyone—lower % niacinamide can be enough for sensitive skin
📌 Studies and dermatology insights show niacinamide is effective for brightening and oil control, but higher concentrations can increase irritation risk in some users
✨ Final Result:
Clearer, more even-toned skin with reduced oil and visible improvement in pores and acne marks over consistent use—best suited for users who can tolerate stronger actives.
