    I have seen one advertise and its mentioned that our hair oil content 300 % more vitamin E.

    What does it mean i don’t know

      It’s not clear from the way you have written it. That could simply mean it has 300% more vitamin E than skin sebum or some product. When analyzing claims it’s important to write down exactly the words that they use.

    You mention in the audio that we need to use a “control”. Supposing you take 100 people with psoriasis. You give your cream to these people and in less than 30 days, 87 of those 100 people have noticeable reductions in the inflammation, itching and other symptoms. So without a control, one could say “87% of people trying our cream show noticeable improvement in symptoms within 30 days”. So to add a control, you take what? a competitors cream? or a placebo? What would you use as a placebo cream? Any thoughts on this?

      Without a control you could say that, but your test doesn’t prove your cream works and you wouldn’t be able to make that claim in advertising. To do a proper test you need to have two groups of 100 (or two groups of 50 people). To one group you give them your cream. To another group you give them a placebo cream or some standard treatment for psoriasis. If your cream showed a statistically significant number of people who had an improvement then that would help support a claim that your product worked as a treatment.

    A question about anti-age claims. I think I could come up with some way to demonstrate a reduction of wrinkles but how can someone demonstrate to prevent signs of aging?

    Claims can be supported by ensuring that the ingredients in the panel do what the product claims to do.
