|You may want to stock up on cotton swabs after you read this!|
Once you open a jar of skin cream, you are introducing the product to bacteria from the air and then your fingers when you apply. If you want to minimize contamination, then I suggest skip dipping your fingers in. Instead, load up a pretty container with a package of cotton swabs to keep on your vanity for this purpose. Using a fresh cotton swab is far more sanitary than fingers for keeping your skin care products germ-free.
Another thing that I like to do is refrigerate my products, especially during the heat of summer. Just remember that the hotter it is, the faster those formulations can deteriorate. This is especially true for water-based products. Thus, the best way to safeguard those creams, lotions or serums is to keep them cold for sustaining the life of the product.
By making these two simple changes to how you apply and store your skin care, you will improve its shelf-life and the beauty of your complexion with less chance of using any tainted products!
