Hello everyone
My name is Reuven Lahav.
I am from Israel. I am the manager and the formulator of " Diva -Cosmetics & Parfumes Industry" (Est. !905) third-generation manufacturer of boutique cosmetics. Although I have a degree in Physics and not in Chemistry all the knowledge from my father in law and his father before is available to me, so it is sometimes very easy for me to formulate a new product.
