primrose oil

I just bought a face mask with primrose oil in it. It's for soothing redness and such. My skin has been a mess since 8 weeks and I am now 19 weeks.  Anyways I happened to come across an article that evening primrose oil is not safe during the first two trimesters as it can induce labor basically. Do you think this is when taken orally? Does anyone know if it's safe for skin? I am not going to chance it unless I find out that it can't cause harm just placed on my skin
