If you use a daily moisturizer for your face, you could mix it w/ your foundation. It’s best if you don’t mix into the entire bottle/tube of the foundation to make it lighter, instead every time you need/want to use foundation just mixes a few/couple(2) of drops/dollop of moisturizer to one drop/dollop of foundation. Keep doing that til you get enough to cover your face. This would make the foundation lighter in shade and act as a tinted moisturizer.

Using white foundation like what the previous answer suggested can also help too, just don’t mix it into the whole bottle like I explained above but try using both the white foundation and your reg. foundation in equal parts. See if it’s like enough, if it’s too like add a dab of the reg. foundation, if it’s still dark add a dab of white foundation; keep doing that til you get the color you need/want.

The white eyeshadow trick is something new, first time I’ve heard of it, if you really want to try that then make sure that the shadow is matte(solid color) w/ no shimmers/glitters. Also check the ingredients of the eye shadow and white foundation to make sure that none of the ingredients can cause breakouts for you.

what my friend uses because she is such a light skin color she cant find her fondation color, she put a little white eye shadow ( if you buy it be careful not to get sparkly white eye shadow )
Just blend it in when you put your foundation on, or you could buy white foundation and apply ONLY A LITTLE on =&h=350&w=350&sz=29&hl=en&start=13&um=1&tbnid=zs9yZin7w0NXEM:&tbnh=120&tbnw=120&prev=/images%3Fq%3Dwhite%2Bfoundation%26imgsz%3Dsmall%257Cmedium%257Clarge%257Cxlarge%26hl%3Den%26um%3D1
