Do Mineral Makeup Products Have An Expiration Date?

Expiration Dates On Mineral Makeup Products Have Some Significance

When purchasing your mineral makeup you may have been advised these products have no expiration date, or have indefinite shelf life.  As a rule in regard to mineral makeup products, this is true to a point.  Many individual ingredients possess an indefinite time line for expiration due to their composition which is what promotes their stability. 

Dry, raw ingredients when stored properly by the manufacturer maintain freshness levels beyond what a consumer would experience with the finished makeup product.  For instance, our ingredients are stored in airtight containers which are then stored in 'no light' and 'no humidity' conditions.  Moisture, air and light are what create the deteriorating process for mineral makeup products.  Plus the way a raw ingredient is utilized also creates a shorter shelf life. 

Liquid makeup products for instance, have a greatly reduced shelf life since the dry ingredient will go through a chemical reaction process once added to a liquid cosmetic formula.  This includes skincare products as well.  The graphic to the right is only an example and is dependent on the type of formulas and how they are used.

Some of you may have already seen this symbol, or weren't sure what it meant, but it is the indicator you want to see on any beauty product to be assured from the date of purchase which you should mark on the jar somewhere, to when opened, to when used by.

We have incorporated this same symbol on all of our mineral makeup products with our new packaging, advising our customers of the recommended 12M (12 months) after opening for superior results providing the ultimate in color and freshness.  However, you could extend our eye colors to 24M due to being highly pigmented and using the clean application we provide with each use.  Monitoring timelines is the best investment in keeping skin looking great and knowing when it is time to toss it.

Certain Factors Determine An Expiration Date

As a Mineral Makeup Look: If you are using your mineral makeup just for concealing imperfections or to simply enhance your complexion, then you may be able to enjoy the product for quite a long time, depending on the brand.  Deterioration as mentioned earlier is caused by light, air and humidity, so you may even see a loss in pigmentation of your minerals when looking at them in the jar.  However, once they meld with your moisturizer or you apply with the moist method, you can see a slight increase in the pigment that is lossed in the jar, restore on the skin.  Yet, the finished look still will not be as rich as when the minerals were new.

As a Mineral Makeup Sunscreen: If you're looking to use your mineral makeup products as an added sunscreen since we know that zinc oxide and titanium dioxide are FDA approved as sun blocking agents, then expiration dates do matter.  All OTC sunscreen manufacturers and dermatologists recommend purchasing new sunscreen every year.  Even if you have unused portions, they are deemed to lose their effectiveness (potency) after a year.  Mineral makeup is no different in this context.  Repeated opening and closing of the minerals eventually degrades the mineral ingredient portion.  Storage, such as on the counter, in your purse, or in your bathroom are all contributing factors for accelerating the process.

Our Recommendation For Your Mineral Makeup

Assess what and how you use your mineral makeup and then decide what is best for your skin.  If a jar remains unopened, since many of our customers stock up on their foundations for instance, indefinite shelf life holds true.  However, we do recommend discarding your mineral makeup foundation after it has been opened for at least a year.  And don't just do it based on the mineral content of your makeup foundation whether you use it as a supplement to your sunscreen or not, but also to enjoy the richer pigments and botanical ingredients we utilize in our formulas for the best skin conditioning makeup finish. 

All other mineral makeup products, if stored properly after opening, should for the most part retain much of their pigment due to the level of color intensity we create within the individual formulas.   But we have to preface this with ......

Fresh is always Best!
