Sephora Returns Policy
If for any reason you wish to return an item to Sephora, products must be returned in new or gently used condition. In order to obtain a refund, the goods must be returned within 60 days of purchase.
Sephora purchases can be easily returned for FREE to any in-store Sephora locations or by mail using pre-paid return shipping labels supplied with the goods when they are delivered.
It can take up to two weeks for your return to be processed if sent by mail to Sephora where the items will be checked before a refund can be issued. Once the return is processed Sephora will let you know via email and you will be refunded via the method used to make the original purchase.
