No. 7 Laboratories range. Any good?

[peaceanddove]

I've used the No. 7 Protect & Perfect Advanced Serum for years and love it but wondering whether to upgrade to the laboratories range? I'm particularly interested in the line eraser serum. Anyone tried it?

I’ve been using the serum since it came out, I’m on my fourth bottle. It really is very expensive for only 15ml of product but it lasts me 4-6 months. It doesn’t work for everybody if you read the reviews on Boots lots of disappointed customers.
It works for me but only up to a point. It completely removed my 11ses in about 6-8 weeks but couldn’t see a difference anywhere else.
I use a tiny bit and only apply to actual lines , on clean dry skin, rub it in gently wait a few minutes then continue normal routine. First tube I used it twice a day, now only once. I know it won’t turn back the time anymore but I secretly hope it has a preventative effect.
I was intrigued by the other 3 products but after reading the ingredients I decided they are too harsh and too reliant on marketing hype so would never use them even if I got them as a present.

Thank you x
