Colour changing foundations

I tried putting on my foundation with a brush yesterday, something I’ve never done before. It looked and felt much better. So how often should I wash the brush if I continue to do so? If I wash it after each use it won’t be dry by the next time I need to use it. And are some brushes better than others? And which foundation is better suited to the use of a brush? What I find is that the older I get the less make up I use but the longer it takes to apply.

I have also used the one from Avon for years , it is good and cheap as chips but recently someone said the formula had changed and they weren’t as happy.
I can’t comment on that as I haven’t bought any recently, when I did buy it I got it from Amazon as I don’t use an Avon rep.

I have used a similar product from Avon for several years and it is light and easy to apply and looks very natural.

I bought some recently, as the reviews looked so good. It felt lovely on my skin, went on easily with a brush, and changed colour as it said. But after a couple of hours, it was really greasy (I hadn't used moisturiser beforehand), so I've gone back to using my Revlon foundation.

I bought Smooch it goes on white adapts to actual skin tone. Initially I was impressed but later on in the day it showed up my orange peel skin. It settled in every single pore and line not impressed at all.

Just checked - on Amazon -;£42 for 2 small bottles

Dr Jart colour correction cream is similar, that it adapts to your skin colour.set it with powder. Hides the redness on my cheeks.
I now don’t bother with foundation.
I have never heard of your recommended one, but I would give it a go. Is it expensive?

I’ve heard of it and have been wanting to try. Will buy this week
