Description

Technical Field

[0001] The present invention relates to the field of skin care, and particularly to a skin care composition for anti-inflammatory acne treatment and repair of acne-prone skin, its preparation method and application. Background Art

[0002] Acne, as a common skin disease, its pathogenesis involves multiple factors such as excessive sebum secretion, abnormal follicular keratinization, proliferation of Propionibacterium acnes, and activation of inflammatory responses. Existing treatment methods such as topically applying chemically synthesized ingredients like salicylic acid and benzoyl peroxide can inhibit inflammation in the short term, but long-term use is likely to cause damage to the skin barrier, dry desquamation, and even lead to drug resistance. Antibiotic drugs can inhibit bacteria, but may exacerbate the imbalance of the flora and cannot achieve root cause repair.

[0003] Some natural plant ingredients are used in acne treatment products due to their anti-inflammatory properties, but their active ingredients have poor permeability and insufficient stability, making it difficult to reach the dermis layer to play a role. Moreover, they cannot meet the multi-dimensional requirements of antibacterial, oil control, and repair.

[0004] In summary, developing a skin care composition for anti-inflammatory acne treatment and repair of acne-prone skin has important value and significance. Summary of the Invention
