Doctor PA having a long scratch scar on hands.. Ask whether can use for the product.. 2 weeks from now the scar.. Also some acne mark... Doctor give the sample to her... Ask her to try on it first.. Doctor will see the result from his nurse.. If result okay he will consider start to use... Doctor now less major operation.. All. Minor procedure and consultation.. He prefer clinical paper rather than testimonials.. He had gone through the clinical paper... Know the product is good.. But less patient he having now... Agree with prevention is better than cure...
