Styledotty.com Authenticity Guarantee:

By purchasing directly from the brand and its authorized retailers ( listed on the brand's website) we guarantee the authenticity of products. We recommend customers should research the products well in terms of expiry, packaging seals, skin compatibility, and product performance before making a purchase. Western retailers typically do not print the expiry dates or seal the products. Instead, a PAO (Period After Open) symbol is printed as a reference for the expiry date or best before use time period. Certain US-based retailers may not even print PAO hence in this case use best practices to store and use the product within six months.

 12 M indicates: Use the product within 12 months after open.
