Useful to add to your makeup kit or collection - 31-12-2018 by

this is super useful to add to your makeup kit or collection and is very versatile! Even though glossier is not in Australia and I love their skin tint, I find I can achieve a similar consistency through mixing this in with drugstore foundations. You can also add a tiny little bit of this into dried up eyeliner pots or other creams and liquids!

Very essential for cream based foundation - 06-11-2018 by

Foundation thinner is absolutely an essential for cream based foundation like RCMA 5 part series or VK palette. Thinner made a huge difference in texture which made it so much easier to apply and blend it on face also it saves amount of cream foundation I used. Without thinner, I scoop RCMA foundation about a pea size and warm it up but now I use thinner and add one drop for a quarter of pea size or sometimes half size of pea foundation for extra coverage.

Thinner is liquid and feels like oily texture however it doesn’t affect my skin type/ foundation as I have combination skin. The bottle is small but a little goes a long way and will last long time!

Handy to have - 31-10-2018 by

I've bought this for my kit to use with my pallet.
Tried it last week end for my sis in law baby shower and loved it. It helped spreading the foundation beautifully!

Absolute must have - 25-10-2018 by

I initially bought this product for the rcma foundation I have in my kit (which it works excellently for) but have since used it with other foundations and cream products that are too thick, drying out, heavy or even slightly cakey (such as kat von D's foundation) and it also works perfectly at liquefying them and making them a more workable product. I generally use 1 drop to liquefy a product and 3+ to sheer it down to a softer coverage, so the bottle lasts you forever as well.

must have for cream contour products! - 06-09-2018 by

I purchased this for my cream concealers and cream contour palette as I noticed the product was getting a bit dry and hard to budge. One drop of this every so often on your product and it works wonders, highly recommend

Also, if you have kat von d's foudnation....it'd be AMAZING for that i reckon!

Does the job well - 27-08-2018 by

This blends in very well with cream and liquid foundations to thin them out if they are either too thick, or you want to give a foundation more sheer/light coverage. This has been the only thing that allows me to use my Becca Ultimate Coverage foundation without looking like I’m wearing a mask. You only need a tiny bit so the bottle will last forever. A great product to allow you to customize any foundation you have to the preferred coverage and texture.

Awesome - 12-06-2018 by

This works really well. I do love a full coverage foundation, but sometimes i want it to look a little more natural and this is the perfect product to help me. It has saved me from buying multiple other foundations because it transforms the ones i have!

Beautiful product. - 28-05-2018 by

Mixes great and looks amazing on all skin.

Essential - 22-05-2018 by

What can be said for a product like this? It's not flashy or sexy. It just works. It does a boring job, but it's an important job, and it does it well. You can use it to thin any cream product, especially important for foundations, or as a blender to make powders pop. Honestly, I would usually make my own thinner as it's just two ingredients that are easy enough to buy, but in some class and professional environments products need clear labels and listed ingredients for liability purposes, and given how affordable this is, how little you use, how rarely you use it, and how long you can keep it I don't begrudge buying it.

It's the sort of thing that many people would forget to add to their kit, but really you should not be without it.
