How Niacinamide Helps Control Oil
Niacinamide regulates sebaceous gland activity, reducing the amount of oil the skin produces throughout the day. Instead of stripping the skin like harsh mattifying products, niacinamide strengthens the barrier and improves moisture balance.
A 2006 study in the Journal of Cosmetic Dermatology found that topical 2% niacinamide significantly reduced sebum excretion rates over four weeks.

Why Oily Skin Needs Niacinamide
Oily skin isn’t just about shine it’s often the result of dehydration, hormonal imbalances, or weakened barrier function. Niacinamide tackles the root causes by:
- Balancing oil and moisture levels
- Strengthening the skin’s natural barrier
- Calming inflammation and redness
- Preventing clogged pores
- Reducing post-acne marks and dullness

Dermatologists recommend starting at 5% and using it twice daily for best results.
Niacinamide vs Other Ingredients for Oil Control
Niacinamide vs Salicylic Acid (BHA):
BHA exfoliates; niacinamide regulates oil. Together, they’re ideal.
Niacinamide vs Retinol:
Retinol speeds up cell turnover but can dry skin; niacinamide balances it.
Niacinamide vs Zinc:
Zinc reduces inflammation but not oil glands directly. Niacinamide works at the gland level.
Best Ingredient Combinations for Oily Skin

- Niacinamide + Salicylic Acid – clears pores and smooths skin
- Niacinamide + Green Tea Extract – antioxidant + oil control combo
- Niacinamide + Hyaluronic Acid – keeps skin hydrated while balancing oil
