The Science of Personalized Care

The skin iD clinical trial is the largest Neutrogena has conducted to date, with 500 acne sufferers. skin iD personalized regimens were compared with proactiv's acne solution in a randomized double-blind, placebo-controlled Neutrogena clinical trial. The results are in and they're incredible!

Over 500 qualified subjects were enrolled in a 8-week treatment to determine the safety & efficacy of a personalized acne treatment.

Background

Neutrogena Dermatologics™ conducted a double-blind, randomized, placebo-controlled clinical trial – considered the gold standardfor clinical research trials – that evaluated the safety and anti–acne efficacy of our personalized acne treatment. A clinical trial is a research study used to determine whether new drugs or treatments are both safe and effective as governed by the Federal Drug Administration. While clinical trials aren't required for over-the-counter acne care products, Neutrogena Dermatologics wanted to go above and beyond to prove we're effective.

Clinical study design

This clinical study was conducted by a board certified dermatologist, Dr. J.H. Herndon, of the Presbyterian Hospital of Dallas, Dallas, TX, and Dr. Thomas J. Stephens of Thomas J. Stephens and Associates in Carrollton, TX from September 2007 to January, 2008. Over 500 acne sufferers of different ethnicities, both female and male, ages 13 and older, enrolled in the study. The subjects were randomly assigned to one of three groups: skin iD™, proactiv™ or placebo control. Subject assignments were balanced across groups with respect to the acne severity, gender and age. Subjects were tracked for a total of 8 weeks to evaluate the effectiveness of skin iD™ personalized acne solution in breaking the acne cycle. Neither the subjects nor the study investigators knew the identities of test regimens during the study. In the lexicon of the clinical testing, this study is conducted under double-blind, randomized, and placebo-controlled conditions, which is the most rigorous, objective and unbiased way to evaluate and compare product performance.

What's a double-blind study?

In a randomized double-blind, placebo-controlled study, some of the participants are given the treatment while others are given a "placebo" (or fake) treatment. Participants are randomly assigned to either the treatment or placebo products and neither the researchers nor the participants know which is which until the study ends-that's what makes it "blind."

In skin iD™'s study, over 500 subjects were divided into the following groups:

• skin iD™ participants
• proactiv™ acne solution participants
• Placebo participants

Why do double-blind studies matter?

When it comes to acne, common sense observations aren't reliable and objectivity is key. Because a double-blind study is one in which neither participants nor investigators know who's using what product, there's no preference or bias in the results. For most types of treatments, the question of how "Treatment A" benefits "Condition B" is therefore best answered by double-blind studies.

How were results measured?

To measure the effectiveness, safety, and irritation of skin iD™, proactiv™ and placebo treatments, these are the key factors that the clinicians examined:

• How fast acne goes away
• Prevention of new acne from showing up
• Reducing total amount of acne
• Visual noticeability of acne condition
• Gentleness and mildness on skin
