Why is the Tightening Serum tube so small?

Our development team designed the size of this product to last 28 days, or 4 weeks, when used as recommended. Rather than an all-over facial product, the Tightening Serum is a targeted spot treatment and should be used on small areas of the face. However, because everyone's skin needs are slightly different, users may go through this product faster or slower than the average person. If you find you are going through your tube of Tightening Serum in much fewer than 28 days, we recommend decreasing your usage slightly, and focusing on the areas that really need the product (fine lines, wrinkles, puffiness beneath the eyes).
