- Niacinamide is an active form of vitamin B3 that can improve skin barrier function and reduce fine lines and wrinkles.
- Niacinamide can also reduce sebum production, shrink pores, and smooth out texture.
- Purging of skin can happen when using a product with active ingredients that can exfoliate off the top layer of the skin.
- Purging will usually last for 6 weeks and the breakout will get better over time.
- Patch testing can be used to determine if a breakout is due to purging or is caused by a bad reaction to a product.
- The Ordinary's niacinamide serum has 10% niacinamide and 1% zinc PCA.
- Clinical studies have shown that niacinamide concentrations between 2-5% were effective with minimal irritation.
