Attached Figure Description

[0031] Figure 1 The graph shows the test results of the moisturizing effect of the products obtained in Example 1 and Comparative Examples 1-5 of this invention;

[0032] Figure 2 The images show the repair test results of the products obtained in Embodiment 1 and Comparative Examples 1-5 of this invention. Detailed Implementation

[0033] This invention provides a plant extract composition based on the concept of plants, with purslane extract as the main component, combined with garlic extract and turmeric root extract in specific amounts, and the three components in a suitable ratio achieve a synergistic effect.

[0034] Currently, it is generally believed that:

[0035] Purslane extract possesses broad-spectrum antibacterial and anti-inflammatory properties, making it effective in preventing and treating skin diseases such as eczema, allergic dermatitis, and contact dermatitis. It exhibits excellent free radical scavenging ability, indicating a significant antioxidant effect, and also provides good skin moisturizing. Purslane contains many important metabolites and various chemical components, such as flavonoids, alkaloids, terpenes, organic acids, and polysaccharides. Its active ingredients demonstrate good efficacy in anti-inflammatory, antibacterial, anti-allergic, antioxidant, exfoliating, keratin repair, skin healing promotion, and sebum secretion inhibition, showing great potential in the treatment of acne. The stratum corneum is a crucial structure for the skin barrier function; a decrease in Caspase-14 levels in the stratum corneum can negatively impact the skin. Caspase-14 is a specific protease, and its reduction affects the dephosphorylation of profilaggrin, thereby decreasing the production of fibroin polymers (FLG) in human skin. A decrease in FLG content in the stratum corneum leads to a decline in the level of natural moisturizing factors, causing changes in skin pH. This change can activate protease-activated receptor-2 (PAR-2), resulting in reduced epidermal lipids and damage to keratinocytes, thereby impairing the skin barrier function. Simultaneously, damage to the skin barrier function increases the likelihood of exogenous harmful substances entering the body, thus worsening the patient's condition.

[0036] Turmeric root extract has a good inhibitory effect on Malassezia furfur, which helps reduce dandruff and can be used to treat dandruff; its strong activating effect on luciferase indicates that it has a good anti-inflammatory ability and can prevent and treat various skin diseases; it inhibits cerebromidase, thereby maintaining the amount of cerebromid in the dermis and can moisturize the skin.

[0037] The main component of the garlic extract is allicin, which has excellent antibacterial effect, strong bacteriostatic property, insecticidal property, no toxicity, no side effect, no drug residue, and anti-tumor effect. It can effectively reduce or eliminate acne.

[0038] In practice, when they are used alone, the moisturizing and repairing effects on the skin are not ideal and cannot achieve the expected effect, but after being combined in a set amount, a significant synergistic effect is obtained, which can be used to replace some commonly used polyol moisturizing agents, increase the use diversity of cosmetics, especially can improve the moisturizing and repairing effect, in addition, they are from natural plants, which is beneficial to the consumer experience.
