Lactacyd Liquid was the first product of Lactacyd. It is a very mild natural skin cleanswer made of simply two ingredients--Lactoserum and Lactic Acid.
I used this way back in college when I had pimples. I was advised to use a mild cleanser because they said that my skin could be allergic to harsh cleansers. As it turned out, Lactacyd is so mild that it could not remove oil and grime off my face. It does not lather and is not soapy. The result was a disaster! I got more pimples than ever! As it turned out, my face needed a stronger cleanser in order to remove the dirt and oils. So I had to stop using the product I bought, except that I had to endure many more pimples for several for months just because I used Lactacyd.
I believe Lactacyd works for other people with sensitive skin but not for me.
Aside from the face, Lactacyd liquid may be used on infants as baby wash, because it is so mild. It could also be used as shampoo, but it is not for me still because I have oily hair.
