Excessive exposure to the sun early in life can make a person look older than he/she really is. Premature wrinkling and skin damage from sun exposure is also called photoaging. Photoaging, unlike natural aging, results in course, dry skin, freckling, skin discoloration, leathery skin, and deep wrinkles.
Now a new procedure that uses a carbon dioxide laser passed over the surface of the skin, improves the look of skin that has been damaged by the sun.
A study, involving 28 patients aged 48 to 78 years old, found that the laser resurfacing produced changes in the skin’s composition and that it was “clearly efficacious in producing cosmetic improvements in patients’ skin.”
Higher volume injections of botulinum exotoxin A at lower concentrations affects a larger area near the injection site. “In the present study, we saw an approximate 50 percent increase in area simply by increasing the volume five-fold. The results indicate that we can add another level of sophistication to the use of botulinum exotoxin A by varying levels of precision. To treat larger, confluent areas, such as the forehead, a larger volume can be used to achieve more spread,” the authors write.
