I'm not feeling well at the moment so my apologies if this post isn't as thorough as I would like it to be. I was spurred on to write this post after my recent mention of the MAC 226 crease brush which is re-released today. The Louise Young LY38 is quite similar in shape and function to the MAC 226 but I find the LY38 much softer on the eye.
The LY38 tapers to a point. The point allows precise colour placement in the crease whilst the tapered hairs blend the colour as you sweep the brush back and forth. The size and shape is great if you struggle with larger crease brushes. It does produce a more definite crease shape for me. If I am after a more smoky application of colour in the outer corner I would use a more fluffy brush to apply colour such as the RBR Crease brush.
It isn't as wide as the MAC 226 and the tapering gives the LY38 a more definite point. The hairs of the LY38 are beautifully soft and it feels gentle against the delicate eye area. However, it isn't so soft that the hairs splay and lose shape as you apply pressure. The feel and shape of the LY38 is also similar to the Cozzette S175. The Cozzette is a little bigger and doesn't grip colour quite as nicely as the LY38 but it is a reasonable alternative if you are looking for a vegan brush.
The LY38 washes well and maintains it's shape after washing. I have not experienced and shedding or breakage of the hairs either when washing or in use. I also like the shaping of the handle which allows for a comfortable grip.
I bought the LY38 brush in Harvey Nichols in London where they have a small display of the Louise Young brushes. You can also buy online from www.louiseyoungcosmetics.com and I noticed that they accept Paypal. The LY38 brush costs £17.
Disclosure: I bought the LY38 and MAC 226. The Cozzette brush was received without cost for review.
