Maybelline baby skin primer is a silicon based clear gel. When applied to the skin it makes it feel super soft & can be easily blended into the skin (I use a pea sized amount for the whole face). It immediately blurs my pores, mattify's my skin and smooths over dry patches. So for a day when you don't want to wear makeup but need a little something on your face to blur imperfection & give you skin a boost this does the trick.
When using baby skin as a primer, I like to let it rest on my face for a minute or so until it sinks into my skin & I can see the true effects of the primer. The primer helps for a smooth foundation application & a even finish.
For the price of just £7.99 Baby Skin primer has really wowed me, it's not a miracle worker but it is pretty amazing for the price. It doesn't make my foundation move around, get oily or patch up in dry areas as some would think a silicon based primer would do.
I really do struggle to see a difference between this & the smashbox photo finish primer, which is a lot more money than the £7.99 you pay for the Baby a Skin primer.
