    The Significance of ‘Wrinkle Index’ 

    Wrinkles. Something we analyze consciously or subconsciously continually in our daily encounters with colleagues, friends, the TV, and the mirror. But the intuitive results are qualitative: “lots” or “a few.” “Deep” or “fine.” In order to measure the effect of a treatment, however, more precision is required.

    Toward that end, we at skinofmine.com have developed a method for quantifying wrinkles. Users can find their “wrinkle index.” But what does
    that index signify? The best way to get an intuitive feel for what the index is showing is by examining a few examples.

    The images shown below were analyzed using the wrinkle quantification tool at skinofmine.com. The tool requires the user to highlight the wrinkles as shown in the green masks in the lower rows, resulting in the wrinkle indices shown.

    The index seems to correlate well with visual inspection; the more wrinkles in the photo, the higher the wrinkle index. With some caveats.
    Shadows in the photos can artificially elevate the index. As can including hair, beards, eyebrows, moles, the jawline, or pimples in the highlighted area. Keeping lighting, zoom, and contrast levels consistent is also important for reliability.

    So, why is the wrinkle index important? Well, if I’m going to splurge on a $100 jar of hope, I’d like to see some results. And be able to measure them.

    Quantifying Acne 

    We used the Skin Of Mine Acne module at skinofmine.com to quantify acne of six individuals, where the severity of the acne of the individuals ranged from none to severe.  In each case, the computer mouse was used to manually highlight the areas of concern for each individual.  Results are shown below. The lower row of images shows the highlighted regions in green.

     

    Quantification results coincide well with visual assessments. Note that for individual 3 (Acne Index of 56) the index would likely be higher if the entire face were exposed.

    Experimenting with Focus on Lips: Plump & Reboost 

    I’ve been curious to see whether I could measure an effect due to an over the counter, topical  lip plumper. I somewhat randomly selected Focus on Lips: Plump & Reboost from CVS.

    I uploaded a “before” photo (mouth closed, no smile) to my account at skinofmine.com and tightly boxed my lips, following the pattern of the demonstration image shown. Lip plumpness: 42.

    I then applied the Plump & Reboost gloss and waited 10 minutes. A lot of tingling, but no discomfort.  I re-photographed myself, again with mouth closed, no smile. I uploaded the “after” photo to my account and again boxed my lips. Lip plumpness: 46. Cool!

    One diet soda and an hour later, it was down to 44. Time to reapply, I guess…

    Quantifying the Impact of Neutrogena Tone Correcting Targeted Treatment 

    I’ve recently become much more aware of the impact that uneven skin tone has on the perception of age. Wrinkles alone are not as good a predictor as a more comprehensive analysis which includes both wrinkles and evenness of skin tone. (And a few other dimensions too.) When I took a good look in the mirror, I noticed discoloration, especially along my cheek bones. A lingering “pregnancy mask” crossed with sun exposure I suppose.

    With uneven skin tone on my mind, I went shopping.  I came home with a tube of  Neutrogena® Tone Correcting Targeted Treatment.  I wanted to see first-hand whether I could measure a difference in the evenness of my skin tone after using the product.

    I uploaded a photo of my cheek  my account at skinofmine.com and measured the evenness of the skin tone, manually marking the area along my cheek bone as the region of concern.  This led to a discoloration index of  “25.”

    I’m now four weeks into the application of the cream.

    I  uploaded a new photo to skinofmine.com and again measured the discoloration along my cheek bone. The result:  “18.”

    These numbers seem to jibe well with my own visual assessment: less discoloration on my cheek. 28% to be precise.

    Yea!  I am glad to see on my own skin that the product is doing what it says it will: correcting tone.

    Experimenting with Olay Pro-X 

    I’m four weeks into an experiment with Olay Pro-X intensive wrinkle protocol. I wanted to see if I could quantify the effect of the cream on my own skin. I’ve been using the creams as the package insert directs, and documenting the effects by taking photos of myself using the PhotoBooth feature of my MacBook Pro.

    Executive summary: it’s working! And I can quantify the difference.

    To begin, I uploaded a photo of my face to my skinofmine.com account and used the wrinkle counter to measure my wrinkle index. Voila. My starting wrinkle index was 121.

    Now for the fun part.  I used Olay Pro-X intensive wrinkle cream twice a day for four weeks, trying to keep my diet and exercise programs unchanged. I again photographed myself using PhotoBooth. It’s really important here to keep lighting and camera conditions as consistent as possible, and also to have the same facial expression in both photos in order to minimize unwanted variability.

    Again, I measured my wrinkle index at skinofmine.com, this time using the “after” photo.

    Ta da!  Wrinkle index is 107.   That’s a 12% reduction.  Definitely worth smiling about.  I was also able to align my before and after photos using the “track changes” function at skinofmine.com and saw through animation that the wrinkles under my eyes were indeed lessened. Ole Olay!

    By the way, this experiment was in no way supported by Olay. Just an honest experiment to test an interesting product.
