The first water solution remover I've tried was Bioderma Crealine (Sensibio) H20 and I've been using this for about a year now but it's not readily available in the US. You can buy it online for about $22-$25 for a 250ml bottle. (picture is the 100ml bottle)
NARS Makeup Removing Water just came to US counters last month and it retails for $28 for a 200ml bottle. The cost of NARS is a bit higher and it comes with less product than BIODERMA.
They both are gentle on my face and do not cause any breakouts. Both products contain water and cucumber. It leaves my skin feeling clean and soft. I've used them both as eye makeup removers and they take off all my gel eye liner, mascara, and eyeshadow without stinging my eyes. I just soak the cotton pad and rest it on my eyelids for a few seconds and wipe off the residual. I've used both to take off my face make-up on days I do not use my Clarisonic and I follow up with a cleanser.
There are slight differences between the two products. First is of course the price. Let's say I take the higher price spectrum for BIODERMA of $25 for 250ml. It cost .10 per ml vs. NARS .112 per ml. BIODERMA also comes in 3 sizes that I know of. They have a small travel size of 100ml, a regular size of 250ml and a bigger size which has 500ml of solution. NARS only comes in one size for now, so it's not convenient for travelling. However, NARS is available in the US and you can only purchase BIODERMA online if you live in the US so you probably have to factor in shipping cost (unless you get free shipping :)). Second is the packaging. NARS removing water is more luxurious and sleeker but has a twist on cap whereas BIODERMA has an attached flip-up cap. Not a deal breaker but I like the flip cap of BIODERMA since I don't have to use two hands to open it. Lastly, I do find NARS makeup removing water has a slight scent to it whereas BIODERMA does not. It's almost like an alcohol scent which it does not contain but that's the best way I can describe it.
Based on price for amount of prodcut and they both do pretty much the same thing, I would probably go back to BIODERMA when I run out of the NARS makeup removing water. I do however feel NARS is a bit more gentle to the skin which leaves it slightly softer and less red after cleansing, it might be because it contains Chamomilla. That being said, BIODERMA removes makeup a bit cleaner the first time around. I guess it just depends on your preference. Hope this helps!
