Everyone’s skin type is different, which can be roughly divided into dry, oily, neutral, mixed and sensitive types. Knowing your skin type and choosing suitable skin care products is the key to keeping your skin healthy and beautiful.
Nowadays, many women are using cosmetics, but some women buy a lot of cosmetics, but they don’t know how to distinguish the cosmetics after using them for a long time. So how to judge the expiration date of cosmetics? Let’s take a look.
Numbers and [M] letters: represent the expiration date after opening.
Starting from the first day of opening the product, it must be used up within the specified opening period. The expiration date of the product after opening also depends on the ingredients. Products with pure natural ingredients and a small amount of preservatives will also have a shorter expiration date after opening. Pay attention to the bottom of the product, there will be a small bottle logo with numbers and [M] printed on it.
[M] represents the month: and the number in front represents the opening time. The expiration date of the product after opening is 12 months.
Use the product batch number: check the production and expiration date online.
Sometimes the production and expiration dates of products may not be listed in detail on the packaging, so we don’t even know whether the product has expired.
In fact, each product has a product batch number, which consists of numbers and letters. Using this batch number, you can check the production date and expiration date.
By product category: estimate the expiration date.
Product category and container will affect the expiration date.
Recommended use for 3 months: Mascara
It is recommended to replace one every 3 months to prevent bacteria from growing. Because mascara will come into contact with the eyes, it needs to be replaced more frequently.
Recommended use for 6 months: Air cushion foundation, eyeliner
Some products have containers that make the foundation more susceptible to air and bacteria, such as air cushion, foundation, and containers with large bottle mouths. These products cannot be stored for too long. They can only be used for 3-6 months after opening. Long-term contact with air will cause microorganisms to continue to multiply, and there is even the possibility of excessive bacterial content.
Used on the face, it will cause severe skin inflammation and continuous acne. When you buy these products, remember to pay attention to hygiene and replace them regularly.
It is recommended to use for 1 to 1.5 years: foundation, concealer, sunscreen.
If it is unopened, it should be stored for 3 years, but once it is opened, it can only be used for 1 to 1.5 years.
It is recommended to use for 2 years: lipstick, eye shadow.
Generally speaking, lipstick can be used for 2 years. If it is left for too long, it may dry out and become difficult to spread. You should also smell it carefully to see if there is any peculiar smell. If the smell changes, you have to throw it away even if you cry.
The above is some introduction on how to judge the expiration date of cosmetics. I hope it will be helpful to everyone.
