Start Simple
When trying new products:

Quality Over Marketing

Storage and Expiration

Conclusion
Understanding labels and ingredient lists empowers you to make informed decisions about the products you use. Take time to read labels carefully, research unfamiliar ingredients, and choose products from reputable companies that provide transparent information.
