Hi Emma, We received your review on the heart shape skin buffers this morning and wanted to reach out personally. We're very sorry that your daughter is not seeing the benefits that many of our other customers are and would love to assist with that. Is she using the full 2-3 pumps of cleanser? It's important that there is enough product on the buffer for it to work most effectively. Is she using the buffer to massage for about 30-60 seconds all around her face, paying particular attention to the t-zone where she is likely most congested? Is she cleansing twice a day? There are many other factors that may contribute to how quickly you'll see results, including her skin type but also any other products she might be using, including sunscreen. We noted she's been using the products for around two weeks and while this is a relatively short time to see huge improvements, particularly with blackheads which can be quite stubborn, you are still within your 30 day return policy window. Of course, we'd love to help you get the most out of your products but you are also very welcome to return them for a refund if you just don't feel they are the right fit. We look forward to hearing from you either way. Petite Skin Co.
