This company, which can be found beautymp.com, sells pumps for many different foundations. They usually have a 20% off coupon code on the top of their site. I purchased the pump for Maybelline's Fit Me Matte and Poreless Foundation (which is a great drugstore foundation). This is what the foundation looks like with the pump on it:
MAC Foundation Pump
I wanted to compare Beautymp's pump to MAC's. The MAC foundation pump is more easily accessible, as it can be found at MAC counters, MAC stores, and various sites online. While it is made specifically for MAC foundations, I found in doing research that it also fits several other brands of foundation. Here is what the Maybelline foundation looks like with the MAC pump on it:
This pump comes with a cap and also twists to lock. Like the Beautymp pump, it has good control and allows you to pump out as much as you want. It is also not a perfect fit on the bottle, but it's an improvement over the Beautymp one. It covers more of the screw portion of the bottle and creates less of a mess. I also like how it's black--this gives it a more sleek look (I know, this is a petty detail). This pump retails for $10, and you can usually get free shipping when you order online.
Overall Thoughts
If you pay full price for the Beautymp pump, it ends up being around the same price as MAC's with shipping. I have read many reviews on Beautymp's products, and it appears that some pumps fit the foundations they are meant to work with better than others. Maybe they just missed the mark a bit on Maybelline Fit Me. I do think their site is innovative, and it's a very cool concept. They are definitely on my wavelength when it comes to the importance of foundation pumps.
If you plan to order the MAC pump for a non-MAC foundation, it's a good idea to do a little research beforehand to see if you can find any information about whether or not it is a good fit for your particular product. If it fits, even if it's not perfect, I think this is a good way to go. It's also worth mentioning that NARS sells a foundation pump for $6, and this is an option that may be worth exploring as well.
I hope this gave you some good ideas to improve your foundation's packaging. While both of these options worked for me, I prefer MAC's pump for my Maybelline foundation. Thank you for reading! Please let me know if you try either of these and let me know how they work for you.
