Product Warning! I have used No7 stay perfect lip lacquer, colour Nectar for years. It has taken me weeks to whittle down what is causing my lips to blister and burn but it is this without any doubt as I have tried it on my friend & my husband (!) who had the same reaction. Boots just sent a standard reply & haven’t asked for it back to test it so are either aware or are not taking it seriously but they must have had other complaints - it has to be a batch fault. Poor service Boots! I can’t get a refund in store as have not kept the receipt. I’ll be avoiding No.7 from now on as this was so distressing - standards have clearly slipped.
