Does megadose Vitamin C have beauty benefits?

The megadose method of taking high doses of Vitamin C has been popular for a long time.

A doctor is personally promoting the vitamin he created, saying that he takes 6,000 mg a day.

I heard that Vitamin C is effective for boosting immunity, preventing cancer, and improving skin health.

I was particularly intrigued because I heard it is effective for beauty.

I observed that it provides antioxidant benefits, promotes collagen formation, inhibits melanin production, and even improves skin tone.

I'm curious if those of you taking megadoses feel any beauty benefits.
