Women wear makeup on various occasions, sometimes they want to place the makeup on themselves, while other times they may want someone who may know more and this is why there are full time makeup artists in some cities.
A professional artist will almost certainly have gone through a number of make up brushes in their career before finding one that seems to work best for them. A wedding for example is a prime example where the bride might be too busy to worry about her own makeup and instead hire an artist, some ladies feel more comfortable doing the makeup themselves and won’t actually hire an artist on such an occasion, in some situations the bride might not even wear makeup on their wedding day.
Makeup brushes are usually used to assist in spreading makeup around the face, and while there is no ideal way of getting makeup to spread on a face, usually artists are well practiced in the art of balancing the amount needed to achieve certain affects. Artists may also be used for performers doing musicals and other performances as makeup assists in helping to make a face glow and be visible to someone sitting far back in the audience.
