Description

Technical Field

[0001] The invention belongs to the technical field of cosmetics and relates to a moisturizing and whitening body lotion containing a composite plant extract and a preparation method thereof. Background Art

[0002] As the climate cycle changes, the periodic fluctuations in light radiation and atmospheric water content will have a significant impact on the human epidermal tissue. The environmental differences between different regions are particularly prominent - the strong ultraviolet radiation in the south and the low humidity environment in the north may weaken the water retention capacity of the stratum corneum and induce epidermal dehydration. This damage to the epidermal barrier function may initially manifest as redness and microcracks. If dehydration continues, it may evolve into scaly desquamation. In severe cases, the cracks can penetrate the basal layer of the epidermis and invade the dermis, causing secondary infectious damage. Therefore, most of the existing moisturizing body lotions play a certain moisturizing role by reducing the contact between the skin and the air or increasing the retention time of moisture on the skin surface.

[0003] The moisturizing and whitening body lotions currently on the market generally have problems such as poor stability of active ingredients and insufficient moisturizing durability. Traditional plant extracts often lead to loss of effective ingredients due to deficiencies in the extraction process. For example, some products use ordinary water extraction or alcohol extraction processes, and the active ingredients are easily oxidized and degraded, affecting the efficacy of the product; other moisturizing formulas rely on moisturizers, which may cause skin irritation. In addition, the compatibility of plant extracts and formula matrices in the prior art is poor, which can easily lead to emulsion stratification and affect the user experience. In response to the above problems, the present invention optimizes the release and stability of active ingredients through composite plant fermentation technology and multi-step ultrasonic extraction technology, and combines specific emollients and thickener systems to develop a body lotion with high-efficiency moisturizing, whitening and stability, filling the deficiencies of the prior art.
