How do Lancome members modify their phone numbers?

Hello, as a member of Lancome, you can change your phone number. There are many ways to do this. First of all, you can call Lancome's official customer service number, quote your name and membership card number, and inform you that you need to change your phone number.

Second, you can contact the customer service of the store or flagship store you bought and tell you that you need to change your phone number.

Finally, changing the mobile phone number is likely to affect Lancome's points and may be cleared, so there is no need to call or not to change. I hope my answer can help you.
