Description
A high-concentration serum delivering 15% niacinamide to calm breakouts, control excess sebum, and refine congested pores. N-acetylglucosamine gently exfoliates to fade hyperpigmentation, while zinc PCA balances the skin's oil-water ratio and supports recovery. The formula's lightweight texture absorbs quickly and is gentle enough for daily use on all skin types dealing with blackheads, enlarged pores, or uneven texture.

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.
