There was once I time where I stayed far far away from any shine inducing/glowy products for fear of them accentuating my already oily complexion. Fast forward a few years and I can't get enough of the glow. I finally managed to get my skin to a place where it was more on the normal side. Surprisingly, it seemed to be producing more oil because it was so dehydrated! Praise the lord for the Glamgldw Thirsty Mud.
Recently, everyone (well mostly everyone) in the beauty community has become obsessed with having the most blinding highlight and I'm no different. I don't have a great deal of cheekbone-age going on so I'll do anything I can to fake it. One of my favourite products to use for this are liquid highlighters. Ones that you can apply to the tops of your cheekbones or mix in with your foundation to change the finish and add luminosity.
From the swatches you can see that opacity wise they're almost identical. The only differences are the textures and slight difference in colour. On the left the Cover FX has a more rose golden tone and is slightly more reflective if you're wanting that tin man look. On the right the Maybeline has a lighter more frosty pink tone.
Price wise the Cover FX Enhancer Drops come in at an eye-watering £34 for 15ML. For the quality of the product I get it - it does exactly as it says on the bottle and last for a long time. You get a molten metal like highlight with the smallest amount when you use it on the cheekbones and you can mix it with your foundation to change the overall finish (my favourite use for this.) The packing is beautiful, it feels expensive with its snazzy dropper. The Maybeline Strobing Liquid is a more reasonable price at £7.99 for 25ML (so you get even more product for your money) but I don't enjoy mixing it in with foundation. It has a far more mousy texture that I notice doesn't gel well with whatever foundation I use it with but alone as a highlight its simply stunning.
Do you need both? Of course not. But if you want both then you do you.
If you want to treat yourself and you enjoy making custom foundations then I'd say go with the Cover FX Enhancer Drops. But for the purpose of purely highlighting and if you're not 100% sure on liquid highlighters Maybeline all the way.
