Cosmetic Safety and Expiration Dates:
How to know when a product becomes contaminated or expires
Cosmetics aren't required by law to have expiration dates, so you can't just look at the label to know when a product has expired. Experts vary in their guidelines, and expiration dates are simply "rules of thumb". A product's safety may expire long before the expiration date if a product hasn't been used, or stored, properly. For example, products exposed to high temperatures or sunlight may deteriorate well before their time.
From the moment you open it, the life of a product decreases and bacteria grows. It is important to treat cosmetic products with care. Keep all cosmetic products (make up and skincare) in a cool, dry, place and remember that any product which changes color or smells should be discarded immediately.
We don't think twice about throwing away milk when the expiration date comes, and it should be the same with make up and skincare products. The preservatives added to cosmetic products can degrade over time and may no longer be able to fight bacteria. The cosmetics you use should be as fresh as the food you eat. As a general rule, expiration dates begin the moment a consumer uses a product. After products are opened, they will lose their effectiveness.
The preservatives present in cosmetics should kill common bacteria. But, as FDA studies show, a little bacteria is present in cosmetics before we buy them. As soon as you open a new product, airborne bacteria rush in. Touching cosmetics with unclean hands, unclean applicators and/or brushes adds to the bacterial contamination. Another possibility for product contamination is sharing. Never share cosmetic products with anyone, not even other makeup artists. Sharing cosmetics means sharing germs and the chance of contamination is very high. It isn't worth risking infection.
General Rules to ensure Cosmetic Safety:
ü Never use Professional Make-Up Kit products for personal use.
ü Good hygiene is key. Before applying cosmetics, sanitize hands.
ü Always use spatulas to remove product from containers and work off of a palette.
ü Keep container lids tightly closed when not in use.
ü Keep out of sunlight and heat (which deteriorates the preservatives).
ü Never keep cosmetics (make-up and skincare) in a hot car for long periods of time.
ü Never use cosmetic products if a client has an infection (such as pinkeye, conjunctivitis or skin breakouts).
ü Immediately throw away any cosmetics if a problem is found or contamination may be evident.
ü Immediately throw away any products if its color or smell changes.
ü Never add liquid to a product to bring it back to it's original consistency (adding water can introduce bacteria that can easily grow out of control)
Another form of cosmetics which have a shorter shelf life are: "All Natural" products that may contain plant-derived substances conductive to microbial growth. Consider the risk of contamination of products that contain non- traditional preservatives or no preservatives at all. The shelf life of eye-area cosmetics are limited due to repeated microbial exposure.
Product Expiration
The following is a guideline for expiration of cosmetic products. Keep in mind that if the dates have not been reached yet the product changes color, or smells different, throw it away immediately.
Skincare:
Facial Cleansers & Moisturizers – 6 months
Facial Toners (Astringent) – 1 year
Natural Skincare products (all natural body wash, sugar scrubs, etc) – 6 months
Make Up:
Crème Foundation – 4 to 6 months
Liquid Foundation (in a bottle) - 3 to 6 months
Concealer – 6 to 8 months
Powder (loose) – 1 year
Powder (pressed) – 1 year
Eye Shadow & Blush (powder) – 1 year
Lipstick and Gloss – 1 year
Eye & Lip Pencils – 1 year
* Mascara – maximum 3 months. Never keep mascara for longer than 3 months. Never "pump" mascara (air pushes bacteria back into the tube). When a slight odor is present in mascara it is time to throw it out. DO NOT wait until the odor becomes stronger. This usually means that there are high concentrations of bacteria present and infection can occur.
Throw out any cosmetic containers (along with the cosmetics themselves) which have become cracked or are broken.
Brushes and Tools:
Oil and bacteria can get trapped in the bristles of brushes. Wash natural hair brushes with mild shampoo and synthetic brushes with antibacterial dish soap daily. Reshape the hairs and lay brushes over the edge of a counter to dry so that air may circulate. Cleanse all reusable tools with alcohol and discard disposable applicators (sponges, puffs, etc) immediately after each use.
Adhering to these guidelines will not only ensure the safety of your cosmetic products, but that of your client as well.
