I'm 24, and a few years ago, I tried using a concealer brush for my concealer. I continued using the brush for a few days and then noticed fine lines around my eyes. Afterwards, my concealer started to settle in my fine lines. This had never happened to me prior to using the concealer brush. Then, last week, I tried using my MAC 217 brush for concealer. At first, I was very impressed. It blended amazingly. I used this brush for a few days and then while I was out one day, I noticed more fine lines! I won't ever use a concealer brush again. My question is, has anyone had a similar experience? Is there anything I can do about these fine lines? Any advice or shared experiences would be greatly appreciated. Thanks in advance.
