The Science

Clinically proven to be even more effective at reducing the appearance of lines and wrinkles

Setting a new benchmark for excellence, the experts at No7 asked more than 2,600 women to test their new No7 Protect & Perfect ADVANCED Serums.

In two key consumer trials, some of the women had previously used competitors’ serums, some used No7 serums, and some didn’t use anti-ageing serums at all. Of these, more than eight out of 10 gave the new No7 serums rave reviews for their anti-ageing effects, and preferred them to their current regime.

In clinical trials, the scientists at No7 put the new No7 Protect & Perfect ADVANCED Serums to the ultimate test. Not against a placebo – it is challenging enough to show results when testing against a placebo which contains no active ingredients. Instead, they went one step further and tested them against their original, well proven No7 Protect & Perfect Serums, with spectacular results.

2014

The new research, which proves the new No7 Protect & Perfect ADVANCED Serums are even better than before


  • More than 2,600 volunteers
  • 22 separate studies (consumer and clinical trials)
  • Four clinical trials including two key wrinkle clinical studies

The new clinical trials and consumer trials, provide definitive proof that No7 Protect & Perfect ADVANCED Serum and No7 Protect & Perfect Intense ADVANCED Serum are even more effective at reducing the signs of ageing. One of these studies is still continuing. Here are the results so far.

 

The key studies

Three new trials on 180 women

  1. A three month trial on 80 women using No7 Protect & Perfect ADVANCED Serum. This was done as a split-face trial over two separate groups. Group 1 was double blind and consisted of 50 women who used the new serum, No7 Protect & Perfect ADVANCED Serum, on one half of their face, and the original No7 Protect & Perfect Serum on the other half of their face. Group 2 was single blind with 30 women testing the new serum on one half of their face, and the other half left untreated (dividing the trial group like this enabled the scientists at No7 to observe any variations in the untreated group, which meant they could be more sure that the effects measured for the new serum were genuine). MORE >
    This trial was conducted by a clinical research organisation in South Africa, and wrinkles (crow's feet and under-eye) were assessed by a dermatologist using a published expert grading scale. The majority of the women were 24 - 40 years old (this product is primarily aimed at women aged 25-35) Wrinkle assessments were made before and during the trial period, at monthly intervals. Images were also taken with Visiosphere™ (a highly sophisticated face-scanning system that provides 3D images of the topology of the face) and skin moisturisation was measured using a Corneometer™

  2. A six month trial on 80 women using No7 Protect & Perfect Intense ADVANCED Serum. As with the trial using No7 Protect & Perfect Intense ADVANCED Serum (above), this was done as a split-face trial over two separate groups, with 50 women in Group 1 (double blind), and 30 women in Group 2(single blind). MORE >
    The majority of the women were 35-50 (this product is primarily aimed at women aged 35 – 45 years old). Wrinkle assessments were made in the same way as for the first trial.

  3. A 12 day patch test at The University of Manchester, comparing the existing serums to the new serums, involving 20 women. MORE >
    This trial was conducted by Professor Chris Griffiths and his Skin Research team at The University of Manchester, using the same patch test protocol that he carried out during his original research on No7 Protect & Perfect Serum in 2005-2006. The product was applied over 12 days under occlusion on photoaged forearm skin, before biopsies are taken and repair to the skin assessed by immunohistochemistry (tissue specific staining for markers of repair e.g. fibrillin).

Why conduct clinical trials? To provide robust, incontrovertible evidence of just how effective the new products are, and what they can achieve.

 
 
 

The results

No7 Protect & Perfect ADVANCED Serum: the proof that it’s even better

The serum was trialled both against the previous serum and against untreated skin, and the results were measured at four, eight and 12 weeks. Crow's feet wrinkles and under-eye wrinkles were assessed by expert grading by a dermatologist.

Crow's feet and under-eye wrinkles: clinically assessed
as less noticeable

The expert grading assessments for crow's feet wrinkles and under-eye wrinkles show that both the new serum and the previous serum show a statistically significant reduction in wrinkle grade, from as early as four weeks. As the trial period continues, the benefit increases with time and the wrinkle benefits for the new serum are even greater than those shown by the previous serum. Interestingly, the untreated group not only did not achieve a reduction in wrinkles, but the appearance of their wrinkles slightly worsened – as wrinkles have a habit of doing, over time, if left to their own devices.

Why trial a facial serum around the eyes, an area where you might expect to use an eye cream? Because the eye area is the one that shows the most overt signs of ageing, where lines and wrinkles are most easily measurable, and so gives the best assessment of the anti-ageing performance of the serum.
