We do get a lot of question re the expiry dates on Korean beauty products. I know there's nothing better than receiving new make up. You get super excited, and then you see May 2016 on it. Of course that is worrying and you feel cheated. The last thing you want is an old expired lipstick or face mask.
No panic, stay calm!!! You're probably looking at the manufacturing date and not the expiry date. Korean dates on products are EITHER the manufacture date OR the expiry date. The trouble is it is usually written in Korean. General rule of thumb is that a product is okay for about three years from the manufacture date. So next time you get really confused, this is what to look for.
Using expired products or products that have been open for too long can be harmful to your skin because it’s had time to change chemically and even take on other parasites that can cause your skin problems like irritation and break outs.
If you’re unsure of the manufacturing/expiry date because you can’t remember when you opened it or the date is smudged, a general rule is that it can be 3 years from the manufacturing date if unopened and 1-2 years after opening. See below a guide that gives an idea how long you should keep your products. However, remember that if your cosmetic has a weird smell or it's colour has changed, don’t hesitate to throw it away. It’s better to be safe than sorry.
Perfumes with alcohol - about 5 years
Skin care- minimum 3 years
Makeup- from 3 years (mascara) to more than 5 years (powders)
Expiration dates may vary depending on the manufacturer.
Do I follow the rules above, yes but I have one lipstick that expired years ago and I still cannot throw it out. I don't use it anymore, the colour is wrong but it is the lipstick I wore at my wedding. A bit silly but I somehow cannot get rid of it. Otherwise I am very good of clearing out my cupboards of stuff I do not use anymore. They are either the wrong colour, or a bit of impulse buying or I totally forgot about them. On my last trip to Havanna, Cuba I brought with me all my unused make up that had not expired yet. I made all the chambermaids in my hotel very happy! Have a good clear out!
