I have this one eyeliner, not sure how long I've had it. I'm thinking it might be time to throw it away, but I don't wear a lot of makeup and I finally found this one, but I can't remember where I bought it.

Hi Dianne,

If the eyeliner is still unopened, it should be fine for many years. Once products are opened, they will degrade since they've been exposed to air.

I usually keep pencil eyeliner for 2-3 years. If it's been a while since I've used it, I'll resharpen to expose new product.

If it's liquid (and has not dried up), I'd say 2 years should be safe.

I would go longer on foundation or blush, but don't like to take chances on any products that I'll be using close to my eyes.

Hope that helps!

I use an eyeliner for 2-3 years maximum.

Great advice, thanks so much...I really should start paying attention!

You should only keep products for 3-4 months. Although they have a longer shelf life, they are meant to be used before that. Generally someone who uses mascara (for example) every day will not have it for 2 years. It will be gone by then. you should be really careful with anything that is going near your eye and use only new products.

If you are using natural cosmetics, these should be thrown out sooner. Regular cosmetics contain ingredients that do help prolong shelf life.

Most store-bought makeup will last for years, as long as it is stored in a "cool, dry place" at room temperature, just as most labels say.

I throw away my eyeliner every half a year before. Now i don't use it. Find it is troublesome.

I use pencil eyeliner since last 2 years.

I keep mine for 1 year then I toss it after. There was a time that I continued using my eyeliner and mascara for more quite awhile since I don't really use it that often, I ended up having a sty on my lower eyelid. the doctor told me it can be caused by bacteria which can come from cosmetics. It was awkward, going through my meetings wearing sun glasses in doors! lol....
