One happy reviewer said: "It really works! I've been using this for just two weeks and I can see an amazing difference in a deep frown line on my forehead. The product feels lovely to apply and most importantly it really works!"

Another customer commented: "Wow this does work. I was sceptical reading the other reviews but picked it up for £10 Tuesday offer. It really does work. After losing weight and gaining a few years, I noticed a few deep brow lines starting. After one week of they are virtually gone."

Unfortunately, some reviewers weren't happy with their results. One such shopper said: "Been using a while and not noticed any visible difference. Glad I bought this on offer would not pay full price."

A second wrote: "Bit disappointing. Goes on nicely but can't really see its making a difference and this is the second one I've purchased..so don't think I'll buy any more."

A different response read: "Have nearly finished the vial in a short amount of time. I do not see the slightest difference in my lines. If it weren't for the Tuesday offer I would not have tried it. I don’t think I will be repurchasing again. There are cheaper option on the market which are better."

Despite this, many of the reviews remained positive. Someone else said: "It takes years off you! I have been using this product for a couple of weeks and have found it really works and is beneficial for my wrinkled skin." A fan added: "Stops the lines & wrinkles. I love this serum, works so well on reducing lines. Always get this when on offer."
