Notes before manufacturing process

Recommended manufacturing process itself


I tested the cream first on one half of the face aginst a control consisting of hydrating lotion prescribed by dermatologist specialist. After some time I got convinced, the cream really works and makes the skin look younger.

I tried a commercial product before (Lab Series Age Rescue Face Lotion Anti-Wrinkle) but got a mild irritation. I am not sure about positive effects of this cream. In comparison to this commercial product, I am very satisfied with my cream.

Since then I cannot be without my cream, because I see my face so much more beautiful with the cream. I don't get any adverse reactions from the cream, not even eye irritation when put over the eyes.

The reviews from about 4 friends I gave the cream are not so clear-cut. Noone got adverse effects. Some people say the cream is good without citing any particular positive effects, one friend (40's of age) claimed he cannot see any effect, but I saw his skin as smoother.

Testing of anti-aging creams seems to be not easy to me. One study found that the best performing creams reduced wrinkles by less than 10% over 12 weeks which is not noticeable to the human eye. Another study found that cheap moisturisers were as effective as high-priced anti-wrinkle creams. ( Wikipedia: Anti-aging cream)

How and why the lotion was designed

I was concerned about the price of anti-aging cream and afraid and feeling helpless against the practice of angel dusting. I studied contents of several commercial creams and asked in pharmacies, which ingrediets can be bought. Then I decided to make my own cream.

I designed the cream based on numerous studies and references and reverse-engineering og the ingredients lists of many commercial products, which are listed in the Retune leaflet. I tried to aim at easy availability of the compounds and aimed at commodity compounds, avoiding specialized proprietary products.
