I bought the TSV because, both onscreen and online, they state the eye cream can be used up to the lash and over the lid. However, inside the box was an instruction leaflet which said to avoid these areas. Does anyone know for sure if this product can used as stated onscreen?
If Michelle and/or Tom said it, you can probably rely on that. However, you cannot assume that for you it will be OK without a little bit of pre-testing.
I'd try a 24 hour patch test [close to the face, so the skin on your neck just below your earlobe is normally a good place - skin similar to your face, won't get washed off unnecessarily, and you can easily see it] with any of the products, including the eye cream before using on your face to make sure you don't generally have a problem with them. If you're OK with the eye product, use it around the orbital bone initially. When you first try taking it to the lash line, don't do it on both eyes (that way, if you get a reaction, you will only have one problem eye to deal with). Do you normally use eye treatments up to the lashline without any issues?
The advice you may be given verbally by therapists and staff on a beauty counter may not be identical to the advice on the instructions, as the instructions will have been through the legal department who will always err on the side of caution. Unless you can guarantee that 100% of people using a product in a certain way won't have a problem, they won't let you put it in black and white.
Generally, if you are planning to do something other than what is written on the instructions, proceed cautiously until you are happy with the way you are applying the product... the same also goes if you have a product that's been reformulated - you may have been fine before, but you can't assume you will still be reaction-free.
For example: I used to buy a particular deodorant... it was "improved" and I cannot use it any more as the skin on my underarms began flaking off. Others are still perfectly fine with the reformulation, but not me. I wouldn't even say I was particularly sensitive and reactive.
