Wow - 54 pounds in a lifetime! Yikes!
Let's say that she ingests 1 pound per year for 54 years (ages 18-72). That's 16 oz per year or 1.33 oz per month. Yikes!
The typical tube of lipstick is .12 oz - just scanning the Sephora website at a variety of brands. This means that a typical woman must ingest 11 tubes or so in order to hit the 1.33 oz monthly diet. This would be almost 3 tubes a week, or one every other day! Yikes!
And since the study is for an average woman - it includes some not wearing any at all, some wearing less than the average, and others wearing more than the average. Can you imagine - some gals are eating more than 11 tubes a month. Yikes! Better stay with the natural products, I suppose!
