If you have oily skin, you're probably familiar with the cycle: excess shine by noon, clogged pores, frequent breakouts, and makeup that barely lasts. The good news? One ingredient consistently recommended for oily and acne-prone skin is Niacinamide (Vitamin B3).
Studies have shown that topical niacinamide can help regulate sebum (oil) production, reduce visible pores, support the skin barrier, and calm inflammation associated with acne.
Why Niacinamide Is Great for Oily Skin
1. Helps Control Excess Oil
Clinical studies found that topical niacinamide reduced facial sebum production after consistent use.
2. Minimizes the Appearance of Pores
When excess oil production is reduced, pores often appear less noticeable. Niacinamide is widely used in pore-refining skincare formulations.
3. Supports Acne-Prone Skin
Niacinamide has anti-inflammatory and sebostatic properties, making it beneficial for oily and acne-prone skin types.
4. Strengthens the Skin Barrier
A healthy skin barrier helps retain moisture while protecting against environmental stressors and irritation.
What Percentage of Niacinamide Is Best?
For most oily skin types:
- 5% Niacinamide → Ideal for beginners and daily use.
- 10% Niacinamide → Suitable for oily skin, enlarged pores, acne marks, and uneven texture.
- Above 10% is not necessarily better and may increase irritation in some people.
