If you had to ask me to pick only one makeup product to use for the rest of my life, the answer would be mascara time and time again.  This past week I’ve been testing out the Avon Mark Big & Extreme mascara.  I have tried many, many mascaras over the years so the Avon Mark Big & Extreme mascara had a lot to compete with.   I was especially curious when I noticed that it claims to have an innovative Elastovolumeric formula that increases the length of lashes by up to 54%.
