Hi,on 01/2012, I had a dermabrasion to remove sun wrinkles&freckles. My problem is ,wrinkles + freckles are gone but I got white scars on my face & burns on my chest&arms which look like a vitiligo. I visited my Dr & I'd to take psoralens with a PUVA therapy but it wasn't successful as my pigmentation haven't got back to normal. Now, we're trying Prototopic but I'm sacred of using it b/c of the risks of cutaneous cancers. Can Vitix be safer &as efficient as Prototopic to stimulate repigmentation? Tx.
