Three questions we hear

Can I use it with vitamin C?

Yes, modern formulas work fine together. If your skin feels sensitive, use one in the morning and the other in the evening.

Why does my skin feel warm or red?

At high strength, niacinamide can cause brief flushing in some people. Use it less often, or a lower strength if it does not settle.

When will I see a difference?

Oiliness can improve within weeks; marks and tone take eight to twelve weeks of daily use.
