Strangely, it is heavily used in the cosmetic industry. You now can find glucan in almost any type of creams and eye drops, whatever the women use. To some extent it is used as a filling material because of the fiber properties. Also, it’s used because the molecule glucan is a little bit strange. You can boil it. Say you change the molecule, it cools down and it goes back to the same. It has elasticity so it helps in creams too.
There are studies, not many, but there are published studies showing that it increases the elasticity of skin, less wrinkles and stuff like that. I didn’t do anything like that but I saw the studies and they looked quite legitimate. So, it surely is not a bad thing to do. I did study with a high school student once and she basically had a crème with glucan and put it on the skin cancer of mice and it significantly helped them. I don’t know why, I don’t know how, it was more anecdotal than anything else but it did work. I was surprised more than she was but it might be the next step.
