What a great idea!

A skincare infused primer type of serum is genius! It has a pearly look that you can wear on your own, under your makeup or just on the high points of your face.. options are always good so this is a great product to have being so versatile.. great for a pearl like look!!!

So far loving it. Tried it out today to thin out my Haus Labs foundation. It made it so much better! It was a little too full coverage for me and was drying within an hour or two. Not with this base thinner! Wore it for several hours and looked so glowy! First time using One/Size. Will be trying other products!

Cool product but I’m on a learning curve with it. So far I’ve added too much and have been very very glowy. I have normal combination skin
