are all the formulas the same for these pencils, I get no irritation with zero, for years of wearing but if I switch to perversion or a blue, its bad
my eyes immediately itch and feel foggy, sleepy.
Never had this problem with the color zero.
Considering some shades have shimmer or even micro-glitter, not to mention that it takes different ingredients to produce different pigments, I'd say the short answer to your question is, "No, they do not all have the same formula." I know that Perversion tends to make my eyes a bit watery sometimes but that is because, compared to Zero, it is just a longer wearing product and irritation tends to occur more, at least for me, in longer wearing products. If I were you, I'd look over the list of ingredients in items you CAN wear without irritation and try to only choose colors with those ingredients/formulas. As for the colors that DO IRRITATE, avoid ANYthing you see in the formulas of those that are not in the formulas of products that do not irritate. If you try to stick as close to the non-irritating formula, then slowly branch out adding ONLY ONE NEW INGREDIENT AT A TIME, you will be able to better pinpoint what could potentially cause you trouble in ALL eye-makeups and always remember to use, store, and apply, etc. in a hygenic manner. If you are applying to your water-line, you may want to try only applying to your outer lids and see if you still have troubles. Perhaps you can still wear colors you love, but just not on the waterline. Goodluck!
