The product's description on the Boots website says: " L'Oreal Paris 7 Day Cure Retightening Ampoules have been specially formulated for mature women. With our key component, Collagen Amino Acid Fractions, your skin feels tighter and firmer in only 7 days...
"Presented in 7 individual ampoules, each containing a concentrated dose of Collagen, sealed until use to preserve its benefits and freshness."
Buyers are advised to use one ampoule a day, for seven days.
One five-star reviewer said: "This is a fantastic product! I used this for the full seven days and was really surprised at how effective it was. My skin felt beautifully smooth and tightened - I would definitely recommend."
A second added: "They seemed to make a big difference[,] even my husband commented on the change."
A third said: "I feel like I have seen very visible results from using this product. Has left my skin/face looking and feeling plumper again and my skin texture looks better. Was really surprised at how effective this product is. Will definitely purchase again and I really enjoyed using the little capsules for quantity needed for effective results."
However, one shopper said the ampoules were "very moisturising but left oily residue".
