Hi, a dermatologist gave me some rather controversial information. He told me that he stopped using Erbium because, due to the fact that it is "too cold and doesn't heat up the deep layer of the skin enough, it is also not helpful in smoothing out wrinkles", He did say that it was (because of it) very safe though, and then proceded to recommend the Genesis laser (non-ablative). Is this actually a scientific fact? The erbium laser is used widely. Thanks.
