RCMA Makeup Color Process Foundation Thinner – Adjust Foundation Consistency for Smooth Application – Softens, Revives & Restores Dried Foundations – Pro MUA Essential – Vegan and Cruelty-Free- 1 oz

It certainly works, and you just need a drop or two at the most. Good solution!

Does what it says. It is basic castor oil to help thin RCMA foundations to a light consistency. The advantage is that it is pretty cheap for how far it goes. One drop per application. It will last forever! It is packed in a tight-sealed, small plastic dropper bottle when makes it very, very convenient in a MUA bag. Nothing like cleaning up an oily spill. Thanks for the secure lid RCMA!! :)

This product is a must have in every cosmetic toolbox. My daughter and I mixed this with concealer, and found foundation, and it worked flawlessly in both mediums. This enables us, to use our current foundation and concealer without having to purchase a summer and winter color . This will be a staple in our collection!

Have already used once in a foundation that was just too thick. Worked great! I will continue to experiment. Thank you for this product.

Match’s perfect with current foundation. Does not change the color, only thins it.

I bough this for a foundation I had that seemed a bit too thick for my liking. I put a little foundation in the palm of my hand and literally one drop of the liquid and it was the perfect consistency and went on smoothly and lasted all day!

I bought this to mix with a new bottle of face makeup that was too thick. It worked great as a thinning agent The plastic bottle was sealed but leaked all over had to wash off my hands twice along with the bottle before I used it

Muy buen producto, definitivamente si funciona
