So Clicks always has sales on, where they try to get rid of products that are discontinued etc etc so I found this Essence product for R10!
They have had this product in their sales for over a year now and seem like they have an endless supply (I shop at the Clicks in Cavendish Square)
It definitely helps illuminate the skin by creating a glowy/dewy effect under your foundation but without being too much (eg. some illuminating products are too glittery or make you oily)
I also finds that it helps my foundation blend better when applying to the skin because a base creates stickiness for the foundation to suction onto (I also find that it helps prolong the wear of my foundation)
