Here are some before, during and after pictures. Before using the beauty blender I always wash it with some handsoap first and rinse it until the soap is completely out. Then I squeeze the beauty blender 'dry' so it's damp when you use it.
Here is my skin 'before' only have moisturizer etc on, no filter. I know... It's scary and my skin is kinda bad.
After applying foundation, no filter.
After applying concealer, no filter.
I always use some matte transparant powder to set my foundation and to make it less shiny. It's a bit weird but I don't necessarily use the beauty blender to get a glowy look. I just love how it applies my foundation and makes it look perfect. However I have an oily skin so it's always shiny. That's why I use a matte setting powder so it will last all day. However if you are going for that glowy/dewy looking skin, even more reason to use a beauty blender!
After transparant matte setting powder, no filter.
