There are no natural ways to remove tattoos without interference of the dermal layer of the skin. Some have utilized aldara or alphahydroxyacid in combination with laser which apparently helped the treatment. Many of my patients told me that they were using topical cream to get rid of the tattoo, which they soon realized it did not work. They had purchased it over the internet and it was a scam. Professional tattoos are done in a way that the tattoo pigment is placed deep into the skin that needs laser or surgical intervention.
