I write what I studied about itchy.
This theme is collagen!!
What is collagen?
Collagen is substance in the skin, exactly in the dermis. |
| Skin structure |
Collagen decrease when human are older.
Softness and fresh skin will disappear.
So, cover with collagen supplement.
Really cover?
I researched about it.
Collagen effect
I write both effective paper and subtle effect paper.At first, effective paper
An open-label multicenter study was conducted to investigate the effect of Pure Gold Collagen ingestion on aged skin.
In total, 217 subjects in arm 1 completed the study. The volunteers were aged 23–69 years and all were Caucasians. All subjects had some photodamage and fine lines/wrinkles. One hundred and fifty-seven subjects had a medium or high distribution of fine lines and/or wrinkles (69 of these subjects agreed that their skin was wrinkled).
Easy summary
217 people drank "pure gold collagen". And it says that it has verified.
157 people had fine lines and wrinkles.
What was the result?
At the end of the study, the dermatologists noted that 109 of these 157 subjects (69%) had either visible or significant improvement in their facial lines (Figure 2A).157 people had fine lines and wrinkles.
65% of people improved.
Just be careful.
This is not about collagen, about the effect of "pure gold collagen"
It can be said that collagen is effect.
The second, sbtle paper
In this experiment, women in their twenties took drinks containing collagen for 8 weeks, and various measurements were performed.This is Japanese paper, I translate it into English. (Google Translation)
This experiment was an experiment conducted by a double blind method, and experiments were conducted to obtain objective results as much as possible. There was no significant difference in the moisture content of the skin between the collagen-ingested group and the control group at three time points at the start of the experiment, 4 weeks, and 8 weeks.
However, in the collagen-ingested group, the stratumumabsorption capacity increased statistically significantly after 8 weeks compared with the start of the experiment. Other measurements showed no significant difference, but from this result it is suggested that oral ingestion of collagen improves the moisture retention of the skin.
Easy summary
There was no significant difference in skin moisture content.
Water absorption function increased.
It can be said that collagen reached the skin.
My view
Both of them can not prove that collagen reaches the skin.Both paper can not prove "Collagen that ate both of them reaches the skin".
So, it is effective for those who think that it is effective.
It is ineffective for those who think it is ineffective.
I think so.
Thank you for reading.
