Camellia oil made my red marks and other pigment problems look better almost immediately. And I'd been using Neutrogena products that claim to help and retin-A for a long time with no noticable results. You should try it. Or Rosehip oil. I've recently come across a recommendation for Rosehip oil and it seems to have similar properties as camellia oil, plus tretinoin which is retin A. If you google it, the first vendor will be a UK vendor.

Also, home microdermibrasion kits along with the oil. I've not been very good about doing it regularly, but everyone raves about their results saying it gets rid of redmarks pretty quickly and actual scars in 3-6 months.
