Cosmetics Checker, developed by Miniapp, is a free Android app that helps users check the expiration dates of their cosmetics. The app sources its information from CheckFresh.com and CosmeticsWizard.net, providing accurate and reliable information. Many people are unaware of the expiration dates of cosmetics, which can lead to skin irritation, infections, and other health issues. Cosmetics Checker is a useful tool for anyone who wants to ensure that their cosmetics are safe to use. The app is particularly helpful for those who have a large collection of cosmetics and find it difficult to keep track of expiration dates.

The app covers a wide range of cosmetics, including perfumes, skin care products, and makeup. The expiration dates of these products can vary depending on the manufacturer, but the app provides general guidelines. For example, perfumes with alcohol typically last about 5 years, while skin care products have a minimum shelf life of 3 years. Makeup products such as mascara have a shelf life of 3 years, while powders can last more than 5 years. It's important to note that the batch code is not the same as the barcode, and users should be careful when entering the code into the app.
