SKINN unfortunately uses a few irritating ingredients in almost every product. I've wanted to try a few of their items in the past but unfortunately, they always contained menthol, peppermint oil or other irritating ingredients so I had to pass. I would love if he'd omit those kind of ingredients in a few of his products as many of the other ingredients are very nice. Still hoping for a mint and menthol free lip balm!
I do like his Collagenisis body oil (love the scent!) and his hand cream. Both really nice products.
Regarding Isomers, I have tried a few of their products and just never had any results from them. I think they ones I tried were ones she rated fairly well or didn't rate at all because they were newer at the time. I know they use some irritating ingredients too but not nearly as many products contain them as in SKINN's. Isomers frustrates me though because they are always changing formulas and not letting consumers know. That isn't good for those of us who like to avoid irritating ingredients or ingredients like Triclosan, which she added in her deoderant at some point and which we know isn't a good ingredient to be exposed to on a regular basis.
I've said this a million times and I know people like to ignore it or just simply like to ignore scientific evidence in general but Paula's info on ingredients stems from scientific evidence, not her opinion.
That said, there are many things she rates highly that I haven't liked. They aren't ingredients issues as much as how the product feels, looks, wears or applies. Mostly this in regards to makeup.
