Dendrobium-extract-containing composition and preparation method thereof

Abstract

The invention relates to a dendrobium-extract-containing composition, and the dendrobium-extract-containing composition can improve the problems of skin roughness, dryness and the like caused by skin water shortage, and can effectively resist oxidation and prevent aging. The dendrobium-extract-containing composition comprises the following components: a dendrobium extract, hydrogenated lecithin and plant sterol. The dendrobium extract is prepared by solvent extraction, and a solvent is selected from the group consisting of water, methanol, ethanol, isopropanol, n-butanol, ethylene glycol, 1,2-propylene glycol, 1,3-propylene glycol, 1,3-butanediol, acetone, ethyl acetate, or a combination thereof. The dendrobium-extract-containing composition can well promote expression of keratinocyte AQP3 (3th aquaporin) and enhance the penetration capability of cells, and at the same time has good water locking and moisturizing effects due to the synergistic effect of the various components. The invention also includes a preparation method of the composition, the preparation method has the advantages of simple process and low cost, and a produced product has excellent quality.

Description

Technical field [0001] The present invention relates to the field of cosmetics. Specifically, the present invention relates to a moisturizing and water-locking composition containing Dendrobium extract and its preparation for skin moisturizing and water-locking, anti-oxidation and anti-aging. Background technique [0002] People living in a high-stress and fast-paced life, due to irregular long-term work and rest, unhealthy diet, mental stress, and long-term radiation, etc., it is easy to affect the metabolism of the skin and damage the skin's moisturizing mechanism, which may cause dehydration and cause the skin Rough and dry. [0003] The skin is composed of epidermis, dermis, and subcutaneous fat tissue, and each layer contains water. Modern studies have shown that the root causes of skin dehydration are: the moisturizing structure and activity of epidermal keratinocytes and the continuous weakening of the water supply capacity of dermal cells, which gradually loses the water c...

AI Technical Summary

Problems solved by technology

Modern research shows that the root cause of skin dehydration lies in: the moisturizing structure and activity of epidermal keratinocytes and the water supply capacity of dermal cells themselves are constantly weakened, so that the water circulation function of the water protein channel of epidermal cells is gradually lost, and the sebum membrane loses its defense. , which is not conducive to water infiltration, the structure of epidermal keratinocytes is damaged, and the cells of the dermis cannot circulate and replenish water normally, resulting in dry skin
