Abstract: The present invention relates to a skin external composition containing an extract of green tea produced by an extreme light-shielding cultivation method, which is distinguished from a conventional light-shielding cultivation method of green tea. More specifically, the present invention relates to a skin external composition, which contains an extract of green tea cultivated by extreme light-shielding, in which the amino acid content is remarkably increased by cultivating the green tea by a light-shielding cultivation under a light-shielding rate of 99% or more, thereby obtaining more excellent skin moisturizing, skin protecting, and anti-aging effects.
