Each one of these products I have used, both the high end and low end brand. I hope this helps!
In order to get some brighteness under your eyes, you may consider using an eye brightener. Yves Saint Laurent's Touche Eclat (by the way, I just love saying that with a fancy French accent) is a cult favorite among many, and an awesome product. However, I honestly feel like these products are so similar in the effect that they give. The Maybelline is a great product, and not to mention I really like the sponge applicator.
Mat Velvet + foundation is a wonderful mattifying foundation, loved by many women who have oily/combination skin. The price tag, however, is pretty hefty. A great alternative is my beloved Revlon Colorstay foundation! The consistencies are a bit different, but both are medium to full coverage foundation with mattifying properties!
Laguna is probably my favorite bronzer I have found. I love the packaging, and the color that is buildable. It is also not too shimmery, which I think is perfect for adding warmth to the face and contouring. I found the Sephora Brand bronzer for fifteen dollars cheaper, and an almost exact color. However, this bronzer is completely matte, which doesn't make it an exact dupe. I actually like this better because I love a matte bronzer.
I think MAC makes the best gel eyeliner of the high end brands, but fear not, there is something just as good. The E.L.F. Cream Liner is seriously just as good, and a fraction of the price. The brush it comes with is useless, so make sure you get a good eyeliner brush (be it angled, tapered, or flat). Stay tuned to the bottom of this post for good brush recommendations.
You might have read this post on how I compared the two of these products, but I would be silly not to include these powders in this post. So go and read my other post for more details. Bottom line, the E.L.F. powder is not completely identical, but it is a great HD powder!
I have only used MAC brushes ever since I started getting serious about makeup. I built up a pretty good collection. However, I lost quite a few of my brushes (much to my dismay) and wanted to replace them without breaking the bank. I did a ton of research and ultimately decided on Sigma brushes because they are modeled exactly after MAC brushes (which I feel are the best). The numbers of the brushes even used to be the same. I have been so pleased with these brushes, I am only going to buy Sigma here on out. Check out a full review of these brushes here.
