Q. I’ve recently started to use a primer by bareMinerals.  I love the effect and the way it allows foundation to glide on more easily…. But I’ve started to have tiny dry and spotty patches …. Is this a coincidence – should I stop using the primer? Can your skin still breathe through the primer or is it ‘sealing’ up the pores?

A. The main ingredient in bareMinerals Prime Time Foundation Primer,

is a chemical called cyclopentasiloxane (CPS), a type of silicon, which is very commonly used in skin and hair products.  According to bareMinerals, there is no reason why it should cause your little dry spotty patches: CPS should even out your skin and provide a protective layer but still allow your skin to breathe through it.

We have two thoughts: firstly, you could try leaving off the primer for a week or two and see if it makes a difference.

Secondly, we wonder if you are still applying a day moisturiser or whether you may think the primer is moisturising?  Because it isn’t!  Primers are great at what they do – prepping the skin for foundation but they are not moisturisers.  Choose a good light moisturizer: we suggest opting for one which is free of mineral oil – a villain at blocking pores.
