Blush Mark points/coupons have different expiration dates. If your points/coupons expire before being used, they will be deleted from your Blush Mark account. You can visit 'My points' or 'My Coupons' for the exact expiration dates.
Additionally, please be advised to check if you applied it to a previously unpaid order. If that's the case, you can cancel the unpaid order so the points/coupon would be credited back.
