What is the capsaicin supposed to be doing in the product?
How would a consumer tell that it was doing it?

Used in analgesic product. Very strong skin/eyes/ lung irritant. Raw material should be handled very carefully.

@Vanessa thank you.

Gunther said:

Oral Vitamin C megadoses were already tried in the 70s, and no positive effects on skin were noticed, despite absorption being guaranteed in oral products, unlike topical products.

Vitamin C does nothing beneficial to the skin.

you may be right as all cosmetics do temporary job.

Still market is on.
