This should never be applied to the waterline itself, but should be between the lashes for tightlining.

I can't use it because it burns my eyes and it horrible to remove form eyelids, brushes, and the cake eyeliner itself.

Being chemist, if you really know what was in all of our beauty products, you really wouldn't put any of it on. We've come a long way from the beauty products of decades ago. It's been dermatologist test, so yes it's safe.
Eye drops contain PEG (polyethylene glycol) 400 which is a low molecular weight polymer. So if a polymer is sage for eye drops, the tightline activator is safe for you also. Be beautiful knowing your product is safe to use!!

Question
Can you switch between using water and this product in the cake liner?
Once you add this product to the cake liner, does it actually change the consistency of the liner, making it difficult to use water when you want to. Or is it easy to switch between water and the activator?

NO! Once you use water, the activator won't work, and vice-versa.

You can't really switch between water and tightline activator. The activator forms a kind of waterproof film on the product which prevents it you from being able to use plain water to make a paste. The only way you cango back to using water is by scraping off the top layer and you will lose a lot of product. I have a Black Ebony single and just bought the 3 pan with black, purple, and brown. I've been using the purple with plain water and it does not perform nearly as well as with the activator. It transfers to my lower water line and smudges all over the place. My idea was to have one to use with activator and one for plain water but unless you use the activator the cake eye liner doesn't perform any better than any other dark eye shadow I use to line my eyes with.
It is also very hard to remove it from the brush if it gets a chance to dry before it is thoroughly clean. I've had to soak the tip of my brush in eye makeup remover to make them soft again, so make sure to clean your brush thoroughly after each use.

With this product, you need to use one or the other. I use one half of my cake with the activator, and the other side with water. From what i was told, the activator does not mix well with water. Also, clean your brush after each use of the bristles get very stiff. I have been using it for months, and love it!

I haven't tried the other one, but this one does require you to thoroughly clean your brush after each use or it will become completely stiff and stuck together. I had to soak the bristles of mine in a little bit of liquid eye makeup remover before I could clean properly. I used a mu remover meant for long wear/waterproof eye makeup and just put a little in the cap, just enough to really wet the bristles avoiding the ferrule because water and cleansers can decrease the effectiveness of the glue that holds the brush together. I took it out a couple of times while it was soaking to wipe off as much as I could on a paper towel before it was soft enough to wash.

Just soap and water, but immediately after using. Otherwise, get the brush soft with an application of the activator again, then clean it.

I shampoo mine. It takes awhile to get it clean.
I asked someone at a LM counter, who told me he uses alcohol to get it off. I haven't tried that yet though :)

I clean it with a tissue first, and try to get as much off before I clean with anything water based.

Yes. MUFE makes something with very similar, if not the same, ingredients called Eye Seal

Probably, but you won't be able to go back to using plain water without sanding down the waterproof film that this creates and that will waste a lot of product. I think it is best to have a dedicated cake or shadow liner for use with this product only.

Question
Is this the same as Trish McEvoy's Finish Line?
I have some Finish Line I used to love for a clear-coat eye-makeup setting lotion type of thing, but now that I'm using higher-end makeup, I don't need it (over YSL and Guerlain eye shadows, etc.). I just ordered the Mercier Tightline kit from Sephora, before reading that this activator is "needed" - wondered if the Finish Line would do the same job. Looks identical, similar pricing & size. Thanks.

I've never used the product you mention, but I'm sure it will work well, too. The activator is used to wet the product as you apply instead of water, and it looks like yours is applied over the lid after application.

No, you can still use just water (preferably filtered or distilled) with the cake eyeliner / tightliner.

However, once you use this activator, or any other activator, you can't go back to water. It somehow stays on the brush, and affects the surface of the cake eyeliner.

I would only recommend the activator if you need something really waterprooof, and don't have a problem with sensitive eyes. It is a type of plastic after all.
