Re: "Over 90% of subjects saw an improvement" Clinical Results on Beauty Products

@SilleeMee 

 

first, i want to thank you for stating your occupation.


i had a friend that was a biochemist and she would just laugh when she watched the beauty product presentations. like you, she knew that the claims weren't right because while they may have an ingredient to help problem x, she would say, "ok, but at best, there was a very small amount of the ingredient, just enough to be able to list it on the label".

 

for a few products, she would say that for people that had the worst skin to begin with, would see some improvement, for that reason only.

 

i am not a bio chemist, but just looking at people on and off air that say that they have been using product such and such wrinkle cream or whatever for years and they have more wrinkles then linen, is a clear indication that the product isn't working.

 

i also think that if one doesn't start with truly clean skin, nothing is going to work.

 

like many other things, many of the beauty products are more gimmick then fact.

 

my friend said the first 10 ingredients listed on the label had the largest percent and the rest were mainly fillers and preservatives, or something like that. i don't remember the exact number that she said, but i think it was 10.

 

while this will never be said out loud, on air, but some medication will do a number on ones skin. by that i mean, some medication will dry out your skin.

@SilleeMee Yes.  Thank you.  When I was younger I used Retin-A for acne and kept using it for wrinkles and skin texture issues.  It has worked wonders as long as I use a very small amount in the evening and the next morning I use my SPF.  And speaking of SPF, that is very important as well. But  I am still searching for a product to use on my body because using Retin A all over my body is not an option for me.  So when I have free time to watch beauty shows hoping to find something for my body, I quickly get discouraged because the clinicals sound too good to be true.  When I see that 100% of people saw improvement I gasp in disbelief.  100% of how many people?  And where did you find them?  And oddly enough many of my relatives and friends fall for the clinicals only to find out the products don't work as well for them.  Individual results may vary for sure, but we fall for the hype sometimes.

Sometimes the fine print at the bottom will say the number of participants. It's always small, from around 10 to 100. Also, they are "paid participants" in the study, given products for free. Everything encourages them to report positive results.

I put vendor "clinical results" in the same category as political polling ... i.e.  I don't believe a word of it.

Great points. I want to also add that this figure is based on self reports of what participants “saw” in themselves. There’s no measurement used to quantify or describe what “improvement” is. Self reports are highly subjective.

This is the Gospel Truth!!!  I have wasted alot of money in the last few yrs trying all kinds of different lines claiming this or that and well that really do nothing much at all except hydrate my skin and some inflame it or break me out with bumps!  Since I have rosacea it's a gamble when I buy any of it and likely to cause a flare up most times.

My vent... there should be a disclaimer.  Many of the hosts and vendors have had cosmetic enhancements(surgery).  I tune in rarely so when I do I see a definite difference.  I will not name names but it seems dishonest to claim results from the product when the product was not the determining factor in wrinkle reduction. 

 

And to add----- while I have had no cosmetic surgery I do have connections to those who are in the field and they tell me none of the products really work.  Lots of money is spent for a dream result that does not happen over time.  .

I would add to this list: vitamin C & AHAs. (But there is an etcetera...)

I've always wondered why they don't test at least 100 people.  One hundred people is a good-enough sized group.  I'd feel better if they say "93% of people tested..." because I'd get a better idea of how good (or not good) the product is.  To test 30 people is such a small grouping.  Just my two cents.  :-)
