One of the companies I really love whose products are nut free, gluten free, and vegan is Ofra Cosmetics. I have only tried a select few of their products such as their Nikkie Tutorials Everglow Highlighter and Long Lasting Liquid Lipstick in Nude Potion. But, I have not had any issue with a flare up of dermatitis or an allergic reaction! I have used the highlighter on my cheeks, as an eye shadow, and highlighting my nose & lip. As for the lipstick its a product that did not cause any reaction, however I am not usually a matte finish lips kind of girl, so I typically pair it with my lip gloss from Red Apple Lipstick. For those of you who do like a matte finish, this is a product that is safe for someone with gluten, nut, dairy, or egg allergies.
