Here it's been a week that I tried two oil on the face, the first days I thought the nickel it makes me very soft skin and beautiful skin texture, but that after one week was declared an allergy c !! ! Total patches on the face with itching !!! Knowing that I have a scar on his face that itch now. So I think the balance is slightly without servire but small dose 2 times per week this is enough !!! As against stretch marks I can not say anything because I don not have one. So fragile skin care !!! In small doses !!! Otherwise nothing to say fast delivery.
