Log into Clarins.com and go to '
Upload my receipt' in My Account, where you can submit a photo of your receipt. Make sure the photo clearly shows the entire receipt, including the name of the store, date, item(s) purchased, and price.
As of October 2022, you no longer need to upload your Clarins factory store receipts to earn points as they are automatically credited to your Club Clarins account if you are an active member.
