There is no scientific basis for any of these claims. Retin-A has been approved by FDA as a topical treatment for acne. The agency, however, has not determined whether it is safe and effective as a wrinkle remover. RIFE generator promoters claim that they can insert a person's photograph into their device and diagnose medical conditions. FDA has not approved the marketing of this device, nor is there any scientific basis for this claim.
Promoters claim it rejuvenates old cells, improves memory, and prevents wrinkling.
But there have been no controlled scientific studies to back up these claims. A survey of a large number of different animal species revealed, in fact, that the longest-lived species, human beings, had the highest tissue levels of superoxide dismutase. It's effective for a wide range of disorders, such as cancer, arthritis and sexual dysfunction. It's all natural. It's inexpensive and has no side effects.
