ALA is known as a network antioxidant due to its ability to regenerate/
recycle itself, as well as other antioxidants such as vitamins C
and E, so that they can continue destroying free radicals [12]. Since
available data of formulations containing 5% ALA were successful
to produce a dramatic reduction in facial lines in cases associated
with photo-aging, this compound has gained the attention of cosmetologists
and dermatologists.
