It's been asked so many times lately... Which is best?...The answer is there is no one type that fits all. Saying that one is better that the other is like saying that one wedding dress will suit everyone. Silly hey?? There are so many variables.
What is your skin like (fine lines, big open pores, oily, smooth, scarred, normal) ?
What finish are you looking for ?
The list goes on....
Different foundations can be used through the airbrush machine to give a different finish such as matte or dewy and heavy or sheer coverage.
Your makeup artist should stock a range of foundations in their kit for most skin types. If they are confident and competent they will tell you which is best for you and what will and won't give you your desired look.
Don't be tricked into choosing an artist based on their foundation application technique. Look at the individual artists portfolio and make sure you like what you see. There is so much more to makeup that just the foundation application.
Another thing to consider...What would your artist do if they only offered airbrushing and there was a power outage? Some but not all airbrushing foundations can be applied traditionally. I've actually worked on a wedding where there WAS a power outage, 30 floors up in Brisbane city on a Saturday morning and the power went off for 3 hours !! My trusty traditional foundation came out and the makeup was done in perfect timing.
Trials can be an added cost to your wedding budget but it's better to know what your getting and have experimented with what you like and what suits you than to have any unexpected surprises on your actual wedding day.
Do I personally have a favourite ? No... Is there a time and a place for each? Yes absolutely!!
