This foundation is the holy grail for those that cant stand anything on their face and need medium to sheer coverage, like a better version of their skin.
Over the years I have purchased more around 10-12 foundations from the cheap drugstore ones, to the high end ones and they're all sitting full (and expired) on a shelf. I have a combo/T-zone oily skin and I am not the person who will spend a lot of time applying primers and moisturizers before the foundation itself, as I am lazy and would rather spend this time in extra minutes walking the dog or oversleeping, but first and foremost I can't stand the feeling of having anything on my face. Many layers of products and the foundation & powder on top of them, is my nightmare. I do use the Make Up Forever Step 1 Skin Equalizer, but only for the nose part.
I have been having my eye on this foundation for more than 1,5 year. This would be my last and ultimate effort in search of the right foundation and the last money I would spend. I'm glad I decided to spend 57eur on this one, as it came up to be the only foundation I can stand using and covers my needs. It has medium to sheer coverage, and would not satisfy people who need a good coverage effect. It applies very well, but I would suggest you rather use a firm flat brush instead of the sponge, as it applies way better and minimizes the cake effect. Actually, I have not noticed any cake effect for the 10 hours I am wearing this, so this is another plus. I like to finish it with a translucent powder, as it really gives this nice matte look and doesn't change my natural color to some orangey, yellowish hue. I am going for a very natural look, a better version of my skin, and would rather have some red spots here and there showing, so if you need compete coverage, again... the GA Fusion is not for you.
I didn't find it hard to apply and it doesn't set as quickly as some other users have written, but then again it all depends on how much time you spend doing your make up.
The bottle is a potential deal beaker, I don't like the fact that I have to wipe the fluid (the texture is very liquidy) of the pipette with my finger and the bottle stays open for as long as I'm applying it on my face. I find the liquid formulas way much better for combo skin,that thick formulas. I have also purchased the Bourjois healthy Skin mix foundation, that has great reviews here and combo skin users swear by, but it definitely didn't work on my face, as I cant apply it well, it oxidizes and changes color during the day and will leave you oily pretty soon.
The FA Fusion holds very well during the day, let's be honest there's nothing you can do and no product launched yet that will give you flawless, matte look for the entire day, and I don't even apply more powder during the day. I just go with what I applied in the morning.
You need to have your skin moisturized before applying, but if you can't stand anything on your face just like me, I would suggest moisturizing the night before and washing your face well before applying the foundation. If you use a good moisturizer and you have combo/oily skin, your face should not be dry and flaky the next morning (probably, as every person is different).
No stains on your clothes or fingers, I touch my face all the time, and responds very well to sweat. Well moderate sweat I guess, I have not (and will not) tried it with 32C/90F, as I live in a hot Mediterranean country and would not want to look like a clown when it can get up to 40C/104F easily in the summer.
Overall, until they find the perfect formula for flawless, matte skin all day, this is the last foundation I will probably ever buy in my life. It is well worth the investment (VERY pricey) and if you're thinking going for a dupe or a similar one which promises the same results, I would recommend saving the money to buy the GA Fusion.
