Abstract

The invention discloses a ligustrum lucidum leaf extract capable of resisting fatigue and reducing fine lines and a preparation method for the ligustrum lucidum leaf extract. The preparation method comprises the steps of weighing 20g-50g of ligustrum lucidum leaves, 10g-30g of mirabilite, 100g-200g of polyols and 100g-200g of water, carrying out crushing with a juicer, carrying out ultrasonic treatment for 1h, carrying out suction filtration, and carrying out extraction, so as to obtain a reddish brown extract. The extract has the functions of improving or relieving asthenopia symptoms such aseye sleepiness, ache, lacrymation, foreign body sensation, eye dryness and ophthalmospasm, reducing the fine lines, improving eye region skin darkness, relieving eyelid pouch, avoiding eye perimeterskin early-aging and the like. All substances of the extract are safe and non-irritating, are free of toxic or side effects, can be used directly and can also be added into various eye region nursingcosmetics such as eye region essences, eye region patches and ointment to improve a nursing effect of products. In addition, the extract is simple in formula, readily available in raw materials, low in cost, simple and easy in preparation method and convenient in commercial popularization.

Description

technical field [0001] The invention relates to a privet leaf extract liquid for resisting fatigue and reducing fine lines, and belongs to the technical field of traditional Chinese medicine. Background technique [0002] Visual fatigue refers to a group of syndromes that cause visual disturbance, discomfort or systemic symptoms when the human eye exceeds the load that its visual function can bear due to various reasons, so that it cannot perform normal visual work.
