I have an allergy to pdd and as these products contain no nasties I am pleased to say I have had no reaction to them. The eyeliner is the best product! I use it for a natural look or you can go heavier for a Smokey evening look. It is soft but you can sharpen for a more precise finish if you like. Thank you so much, I was worried I wouldn't find a product that would perform the same as ones containing pdd, but this one is even better!
