Hi Prudvi. How can I stop pilling? It happens only when I use Azelaic acid or granactive retinoid before NMF? Other products in my routine include niacinamide 10%, hyaluronic acid, alpha arbutin and caffeine. They are all water based and nothing happens if I apply NMF directly after them, but if I use Azelaic acid suspension or granactive retinoid, it pills.
