I went to Dollar Tree today and i went to look at some of the make up they have there. Usually i dont buy much make up from DT as most of it is LA Colors and im not much of a fan of their stuff except for their lipstick and glosses. Well anyway my local DT had some pretty good brands of make up, i found some mascaras from Almay and Loreal which normally cost upwards of 7 to 10 dollars at places like Walmart. I love the Almay mascara its wonderful and since they were all only a dollar i proceeded to buy 1 of each color, black, blackest black and brown. I also bought a tube of the Loreal brand which is also great. Anyway i looked at the back of the packaging and saw that they were made in 2010, i heard that opened mascara must be tossed after 3 to 4 months of use and since i only use 1 mascara at a time im wondering what the shelf life of a unopened tube is? i looked online but with no clear answer. Does anyone know how long a unopened package of mascara can last? im guessing i have enough tubes of mascara for about a year. Any answer is appreciated.
