Already lasers can obliterate skin blemishes, topically applied drugs can smooth facial lines and injected agents can remove deep wrinkles. Future products will be faster, better and longer lasting. "New substances will be developed by entrepreneurs," says Brian Mayou, an aesthetic plastic surgeon, "that will be more successful than liquid silicone that we use today to eradicate wrinkles." The next major breakthrough, says Mel Braham, plastic surgeon and chief executive of the Harley Medical Group, will be laser treatment that needs no recovery period.
Nicholas Lowe, clinical professor of dermatology at the University of Los Angeles, adds: "There will be more efficient anti-oxidants to help reduce sun damage and aging. There will also be substances that increase the production of new collagen and elastic tissue to maintain the elasticity of youthful skin."
Lee Shreider, a research cosmetic chemist, says that we may be able to look better without any kind of operation as semi-permanent make-up gets better. "Crooked noses will be improved by effectively sealing on shaded colors that either enhance or subdue areas of the face. We will be able to straighten eyebrows and lips making the face more metrical—which remains one of the keys to beauty, and even close blocked pores with permanent, custom-designed foundation."
The development of the safe Sun tan is a potential gold mine. Being researched at the University of Arizona, but a long way from reality, is the injectable tan. Professor Lowe is optimistic: "There will almost certainly be a safe way of developing a sunless tan that protects against sun damage. In animal research, we've applied creams to guinea pigs that can actually 'turn on' some of the genes that produce pigmentation without any sunlight exposure."
