I never normally used to use a primer, in all honesty all of the ones I have previously tried only served to make my skin oilier, making my make up last for less time that it would normally! The concept of using a primer is to increase the longevity and durability of your make up, and to provide a good base for your make up in the first place. This new Studio Secrets primer is designed to "mask wrinkles and uneven textures in the skin, making the complexion incredibly smooth with a velvety touch. Skin feels soft as if resurfaced". It is also meant to reduce the appearance of dark circles, skin redness and pores, which was the main reason behind my purchasing it. I was worried that this primer may just 'bulk up' underneath my foundation, and not work at all, however I was pleased to be proved wrong. From initial impressions, after first use, this primer definitely softens the skin, leaving it feeling as silky smooth as a babies bottom! It evens out skin tone, dulling the redness I have along my cheeks, forehead and chin. It does make a slight difference to the appearance of my dark circles, but I wouldn't say it eliminates them completely. My pores do not look as visible after application, which is definitely something that gets a thumbs up from me
