pound was shown to protect and repair
y-radiation-induced lesions. In the following
years, many clinical tests proved
its efficacy at treating different types of
skin lesions and illnesses.4,5 Scientists
looked at its nucleotides, the basic units
of nucleic acids. They found that nucleotide
segments of DNA with a molecular
mass from 250 to 500 kD were able to
control the formation of wrinkles. Moreover,
intradermal administration ofDNA
fragments in aesthetic surgery patients
accelerated wound healing.6,7 This paved
the way to research on sodium DNA as
an antiaging active in cosmetics.
