OH. EM. GEE. I can honestly say that I was blown away by these brushes. Okay, okay... let me start off by saying that I had heard of Sigma in the past, and sort of put the company in the same category as ELF in my mind (cheap, but better than nothing). I have a 21-piece set from Sephora, have various MAC Cosmetics brushes, and have acquired several Quo brand brushes as well. I was watching videos of Gregory Gorgeous (and yeah, I thought he was a girl at first) and heard him mention that he loves Sigma brushes. I look into them and it turns out you can get 12 brushes for $89 in the "Essential Kit". The price struck me as super affordable, so I decided to buy them and try them out.
Thus far, I have only seen maybe two bristles shed from any of the brushes, and those came from the large powder brush... which isn't uncommon. The brushes are a great weight, the perfect length, and wash very well. I use Johnson and Johnson's extra gentle baby shampoo (tear free) to wash my brushes, btw.
They grab onto product, apply product evenly across the eye/cheek/face/wherever, and hold their shape. Obviously, if you can afford to drop $500+ and get an all MAC Cosmetics set - go for it. But, if you're not into being mental totally broke... I'd recommend you check out Sigma. The set that I purchased comes with the following (as described by the Sigma website):
Eye Liner - E05 - Creates a precise, firm and even stroke to line the eyes. Synthetic bristles.
Pencil - E30 - For precise application of color on the crease, outer corner, upper and lower lash line. Natural bristles.
Tapered Blending - E40 - Specially designed to apply and blend color on the crease. Natural bristles.
Eye Shading - E55 - Evenly applies pressed or loose eye shadows and pigments on the lid. Natural bristles.
Large Shader - E60 - Creates a smooth application of cream formulas and eye shadow primers. Natural bristles.
Small Angle - E65 - Essential for the application of gel or cream eye liner on the upper and lower lash line. Also ideal for filling in the brows. Synthetic bristles.
Medium Angled Shading - E70 - Applies highlight shades on the brow bone and lightly blend the crease area. Natural bristles.
Large Powder - F30 - Perfect for flawless, even blending of powder products on face and body. Natural bristles.
Large Angled Contour - F40 - Best for application of blush, bronzer and contouring powder. Natural bristles.
Duo Fibre - F50 - Specially designed to generate an airbrushed finish when used to apply liquid foundation, blush and highlighter. Blend of synthetic and natural bristles.
Foundation - F60 - Perfect to apply liquid or cream foundation. Can also be used to conceal large areas. Synthetic bristles.
Concealer - F70 - Ideal to conceal small and defined areas of the face using cream and liquid products. Synthetic bristles.
The one complaint that I have is that the blending brush is a tad large for my liking. I've got larger than average eyes, too, so I think that this blending brush would really be too big for most people. The angled shading brushes, however, are absolutely perfect. All in all, and considering brushes from Sephora or even drug stores can cost you upwards of $20-$35 a brush... $89 is a total steal. I'll let you know if the quality changes over time. But, again, I'm pretty impressed at the moment and am happily surprised with the quality of an online-only brush company.
Have you tried out Sigma? What did you think?
