Okay, first up let's talk about how great value they are; you get a whopping 8g of product for just £4.30. To put things into perspective, at MAC you'll pay £17 for a 6g product, and at NARS you'll pay £20.50 for just 4.8g of product.
What's more is that Sleek blushes are seriously pigmented, so you need only use a tiny amount; lightly tap your brush in once and you'll have more than enough. The staying power is also amazing, and there really is no need at all to re-apply/'top-up' your blush throughout the day. They last significantly longer than both my MAC and Benefit blush, and they honestly do last all day. I also noticed that they fade extremely slowly but evenly, meaning the remaining product won't cling onto dry patches of skin and make you look like you've got some unusual skin condition.
I also love that they make a lot of matte shades. As much as I love shimmery blushes, it's great to find high-quality matte blushes from the drugstore. Most are either chalky or unpigmented (or both, in many cases), but Sleek blushes are neither. You can always dust a little highlighter over the top if you do decide that you want a shimmery shade.
The packaging is pretty great too. As the same suggests, they're sleek; black matte packaging with "Sleek" written in shiny lettering, and "blush" written in matte gold. They're also great for travelling, as there is absolutely no 'air-space' or domes of wasted space and plastic. The clasp can be a little tricky to open, but having used mine for a while now, they seemed to have loosened up a little. The packaging is also extremely sturdy, and it contains a handy little mirror.
Sleek blushes can be purchased at most Superdrug stores, or at http://www.sleekmakeup.com/.
I'll now talk about the individual shades...
Pixie Pink (above) - Very 'barbie'! A light, very cool-toned, bubble gum pink; perfect for pale, cool-toned girls. It's the lightest of the bunch, yet still smooth and pigmented. Pixie Pink is matte, with a particularly smooth texture.
Rose Gold (above) - A supposed dupe of NARS Orgasm, this one is perfect for summer. Rose Gold is pretty much just a medium/dark pink blush with golden shimmer and slightly red undertones. The gold shimmer is very obvious on the cheeks but not to the point where it looks obnoxious, and the shimmer particles give a sheen to the skin, as opposed to the chunks of glitter many drugstore blushes contain. The slight red undertones scared me initially, but it looks so healthy - almost like sunburn, but in a good way! I also have a lot of redness in my cheeks, but the redness in this blush does not highlight this or make my redness look worse.
Flamingo (above) - My favourite! This is a warm-toned hot pink, and it gives the prettiest flush to the cheek. I reach for this one everyday; you can apply it with a heavier hand for nights out, or apply a small amount during the day for a really natural look. Flamingo is definitely matte, yet I feel like it has a slightly healthy, dewy finish to it... I can't quite place my finger on it, but it's definitely not as matte as the others!
Santorini (above) - This was/is limited edition from the Mediterranean collection, and unfortunately I'm not as in love with it as I expected to be. In the pan it's a fantastic bright neon fuschia, but it does not transfer to the cheeks this colour. It's still extremely pigmented, but on the cheeks it's more of a cool-toned hot pink. The texture is also nowhere near as smooth, soft or blendable as my other Sleek blushes. Having said this, Santorini is still a very good quality product and a gorgeous colour, just not what I expected to be. If you love the look of Flamingo but you're cool toned, this is perfect for you as they are fairly similar, with exception to the undertones. I can also see Santorini looking gorgeous on darker skintones.
Pan Tao (above) - I know it's a terrifying colour in the pan, but this is my second favourite Sleek blush! This blush was/is limited edition from the Avoir la Peche collection. It's a delicious peachy-orange colour, and is a perfect summer shade. You can be brave and fashion-forward by wearing it more heavily, or wear it lightly during the day, which gives a surprisingly natural look. The main reason I love Pan Tao is because it's wonderful for layering; put a small amount of Pan Tao on your cheeks, then pop a little pink blush over the top and you've got a gorgeous coral. Doing this means that all your pink blushes are now corals, too! Pan Tao is such a versatile and surprisingly wearable colour, and I honestly would recommend it to everyone, even if you only end up using it for layering under other blushes.
I hope I've created new cravings and I honestly do hope you run (don't walk!) out and pick up some Sleek blushes. The only downside to Sleek blushes?... I now have all the ones I want!
