While I've admittedly worn concealer before, I'm not much of a concealer guy. I'm comfortable with my masculinity and I'm not going to go on talking about how it's feminine or anything such as that, especially on a male's grooming site. However, I will say that it's not something I would typically do in my routine. It isn't as though it would take a long amount of time; I would just forget about it.
I will keep this in case I need to conceal a blemish before an interview or meeting or something, but in the meantime, this will likely stay put on my bathroom shelf.
The product itself was decent. Birchbox did a great job matching my skin tone to the concealer they sent me, but I had to click the thing what seemed like too many times in order to even get a little on the brush. It concealed just fine, but not to the level in which I expected. I expected it to work like my girlfriend's concealer; which covers blemishes almost entirely.. but instead it merely covered up the redness.
Like I said, this may be used for an interview or meeting, but in the meantime... I can't see myself using it.
