Hi, I'm hoping someone can help me with this; I usually use a Chanel eyeshadow base which is pearlescent white like a liquid when it goes on and then dries to almost a powder, it makes my eyeshadow look so much deeper and last all day... but apparently it has been discontinued with no alternative product, so if anyone uses an amazing eyeshadow base or primer which does the same thing could you please tell me what it is as my eye make up looks rubbish today
