Having used liquid developers in the past, I can say that this cream is so much easier to deal with! You can easily dispense the proper number of drops from the bottle tip, and it when it's mixed the tint you end up with a good consistency. I got perfect results using it with the Refectocil Chestnut 4 tint. Will definitely repurchase when the bottle runs out (although this won't be for some time as you only need a few drops per application).
This developer works very well with the Refectocil eyelash and eyebrow tint. It stays in place,does not stain your skin and deepness of coloring is easily controlled with time. I've only used it once yet, but it seems very promising.
Bought this to use with a Bly/black eyelash tint and a brown eyebrow tint. Really pleased with it. As it is a cream it's easier to control the amount of drops you need so less messy. Good size bottle so will last a good while.
