Here’s Why You Should Check That Small Number On The Back Of Your Current Beauty Products
For example, 6M means that the product is best used within six months after the package is opened. 12M means 12 months, 24M means 24 months, and so on. Using the product after the recommended timeframe is still pretty alright, however, it may not be the best. You can usually find this symbol on skincare, makeup, shower gels, toothpaste, and other toiletries.
