You only need a tiny bit of this product, my last one is easily going on a year now. It keeps my face free from freckles and is gentle. I use it in combination with Obagi's tretinoin, and together they keep your face smooth.
Obagi products have improved my complextion since I started using it. Blender, used along with the other Nu Derm products, has proven to bring positive results. I was fortunate to have been introduced to this wonderful product.
