Hello, I recently purchased the EL Double Wear foundation. But I definitely got a shade that was way too cool and clear for me – it looks so gray and ashy to me. I saw that a simple solution would be to add turmeric, but does anyone here have any first hand experience? Does it stain / irritate your skin? How to avoid it being grainy? Pls this foundation was so expensive i want to make it work Thank you very much!
