I love Sonia Kashuk, but I mostly buy brushes from the brand. When I have bought cosmetics, I have been pleasantly surprised, and the Super Sheer Liquid Tint ($10) in Poppy was no exception.
This gel-like liquid blush is fantastic! There is a TON of product here, so you will probably never run out, and a little goes a long way. I am talking about a dab the size of your pinkie nail or less for each cheek. I used a stippling brush to apply and the results are flawless every time.
This product has a pump style applicator, which is really hygienic, but it does put out too much for a whole pump (which the next picture demonstrates). A half a pump is enough! Be careful!
