Re: beauty blender?
I bought the original one online from Sephora, here:
beautyblender® - beautyblender | Sephora
I’ve tried the dupes as well and have found that there is a definite difference. The dupe didn’t seem any different to me than the normal sponge applicators. It was also more difficult to clean and began to wear out in a couple of weeks. The original though leaves a very nice finish, almost airbrushed, and lasts quite a long time.
