Can i use a normal paintbrush to apply concealer under my eye ?

I suppose so, but brushes created for makeup application are much better, or just use your fingers -- that's what I actually do with concealer, and so does a good friend that is a make up artist.Can i use a normal paintbrush to apply concealer under my eye ?
sure, i don't see why not, but why would you?Can i use a normal paintbrush to apply concealer under my eye ?
You can but i suggest u not to, cuz the skin under our eyes are really delicate . Why not use your fingertips its more better and be gentle with the eye area, u dont want a lot of wrinkles or worse under there do u?
yes
You could, but makeup brushes are made with finer bristles for better results when applying makeup. The brushes are all designed differently for different makeup applications. You can get good but fairly inexpensive one at drug store like CVS. The have a good selection at a reasonable price (not that much more than a normal paint brush) but well worth it.
try a makeup sponge or your fingers- the paintbrush hairs may come lose and the concealer may not go on too evenly
Yes you can but you need to be careful about how stiff your brush is. Because paint brushes tend to be extremely stiff and the skin under your eye is delicate, it can get painful if not scratch your skin.
