It is easy to make a list for trips to the supermarket. For other kinds of shopping, it can be harder. For makeup, get in the habit of keeping track of which products are running low. When you are forced to walk through the field of cosmetics at the store, and you find yourself tempted, pull out your list and make sure that you actually need what you are considering.

Another effective strategy is to bring a friend. It is easier to resist temptation when you have someone with you as support. When your eye wanders toward a new dress that you don’t need, your friend can drag you along to another department. Just make an agreement ahead of time that you are going to keep each other’s impulses in check.

Go somewhere else in the store and keep shopping. If the product that captivated you is still appealing later in the shopping trip, you can go back and get it. This is just a fancy way of counting to 10 before you go ahead and buy something that you might not need.These three simple tips will help you from adding more lonely trial sizes to your makeup drawer.
