Gather all your ingredients together. I am using a cheap sun lotion, Rimmel Stay Matte foundation, and L'Oreal Studio Secrets primer. All these products are relatively cheap.
First add about half a teaspoon of primer. You may need to use a knife to scoop up the primer if the jar is too narrow.
Now add a small amount of foundation and mix well with the teaspoon.
The foundation should now look and feel like a mousse. After this, add a few small dollops of sun lotion.
Now it's time to test! I have applied this all over the top of my hand. It isn't very obvious on the camera, but my skin looks and feels a lot clearer and softer!
I've now put the foundation into a little Soap & Glory container, note it was clean! You're finished!
You've now created your 3-in-1 foundation! We added primer so that the foundation looked nicer on your skin, and the sun lotion so you're fully protected. Enjoy!
