Most male actors like using WetOnes because they're unscented, and very fast to remove make-ups including out-of-kit effects. Female actors like the make-up branded ones better, but are surprised by how effective the WetOnes are, (of course, they already come into my make-up room with the preconceived idea that WetOnes are bad for the face from other MUA's). I have worked on several sets where this is a very contensious issue among different Keys.
My experience with this issue, is that most Keys are against using WetOnes. I believe due-to-the-fact that we are dealing with very well-known famous A-listers, so we treat them with high-end products, also they are given the time, then again, those productions have well manned make-up departments.
I find WetOnes are better than baby wipes and generic wet wipes. Make-up branded wet wipes are too expensive for the limited quantity they offer. (Sometimes I use 200 wet wipes in one day, so cost effectivness is important, as well as how well they clean).
Baby wipes are too gentle to remove make-ups so you have to use more than three just to get basic foundation off, also the 650 sheet bulk sized ones tend to dry out faster, even when you reseal the packs as best as possible.
The generic wet ones sheets are too small and flimsy to remove make-ups effectively, hence you have to use more than three.
Make-up branded ones are great for ease of removal, but they only come in small quantity sized packs and are too expensive for bulk purchases.
The LAST thing any actor wants is to have a MUA use several wipes rubbing at their face after a 14 hour day on set. So quicker the better and less steps is key, (That's why I don't use the standard 3 step cleansing routine on most actors because of on-the-clock time, and it's too messy). The exceptions are on certain A-listers as I mentioned above. Then there is the pot-able water issue... But that is for another post, we are talking about wet wipes here.
The only limitation WetOnes have is, is removing S F/X make-ups, here you have to use specialized removers, but WetOnes are great for quickly removing the residue from the removers left on the skin.
