Camellia Japonica: The Ideal Love for Your Skin

Camellia Japonica Extract

Part 1 – Ingredient Introduction

• Camellia Japonica, originally native to Korea, China, and Japan, now has many new cultivated varieties worldwide.
• The flowers and flower buds of the Camellia plant have been used in traditional medicine to treat bleeding and for their anti-inflammatory properties.
• The flowers contain various active components such as triterpenes, multiple hydrolysable tannins, acylated anthocyanins, purine alkaloids, flavonols, and polyphenolic compounds.
• Documented research highlights the antioxidant, anti-wrinkle, brightening, antibacterial, anti-allergic, anti-inflammatory, and anti-pollution efficacy of Camellia Japonica.

Part 2 – Product Introduction

• Camellia Japonica Extract (B) contains high concentrations of skin-effective components like saponins and flavonols. Through our proprietary testing, we have confirmed its antioxidant, anti-wrinkle, soothing, and moisturizing effects. Its antibacterial, anti-allergic, and anti-inflammatory properties are also supported by existing literature.
• Therefore, we recommend Camellia Japonica Extract (B) as a cosmetic ingredient for skin moisturizing, antioxidant protection, anti-aging, and skin soothing.

Part 3 – Experimental Theory

3.1 Anti-Aging & Anti-Wrinkle

• The skin, the organ most closely in contact with the external environment, is primarily divided into three layers: the epidermis, dermis, and hypodermis (subcutaneous fat).
• Collagen is the main structural component of the skin; Type I collagen makes up about 80%, and Type III collagen about 15%. Skin aging manifests as a decrease in skin cell count and thinning of the layers, triggered by external factors like UV radiation and pollution, as well as internal factors like stress.
• Over time, UV-induced damage accumulates in cellular components, promoting the production of protein-degrading enzymes. This disrupts the balance of synthesis and degradation pathways involved in skin ECM (Extracellular Matrix) remodeling.
• MMP-1 enzyme cleaves Type I and Type III collagen in the dermis into fragments. These fragments are then further broken down by gelatinases MMP-2 and MMP-9, a process that leads to the formation of skin wrinkles.

3.2 Skin Soothing

• UV radiation typically stimulates the production of skin inflammatory cytokines such as interleukins.
• Research indicates that IL-1, IL-6, IL-7, IL-8, IL-12, IL-15, MCP-1, TNF-α, and GM-CSF can trigger inflammatory skin conditions like psoriasis and atopic dermatitis.

Part 4 – Experimental Results

4.1 Antioxidant

Camellia Japonica Extract (B) inhibits DPPH radical activity in a concentration-dependent manner. Higher concentrations of the extract demonstrate stronger antioxidant effects.

4.2 Anti-Aging & Anti-Wrinkle

Camellia Japonica Extract (B) suppresses the expression of the collagen-degrading enzyme MMP-1, showing a concentration-dependent response. Higher concentrations result in better efficacy for maintaining skin elasticity and providing anti-wrinkle and anti-aging benefits.

4.3 Skin Soothing

Camellia Japonica Extract (B), across all tested concentrations, inhibits the expression of IL-1α and IL-6, cytokines known to induce skin irritation, thereby achieving a skin-soothing effect.

Part 5 – Formula Applications

5.1 Camellia Japonica Essence

A lightweight, transparent gel essence with a refreshing feel upon application. It spreads easily and absorbs quickly into the skin. The texture is smooth and offers excellent spreadability.

This formula combines Camellia Japonica Extract with Camellia Leaf Extract and Camellia Seed Oil, harnessing the natural healing power of the camellia plant to nourish and repair the skin.

5.2 Camellia Japonica Nourishing Cream

A fine, velvety cream texture that glides smoothly and effortlessly onto the skin upon application. It feels silky and comfortable.

Also enriched with Camellia Japonica Extract, Camellia Leaf Extract, and Camellia Seed Oil, this cream is further fortified with high-efficacy active ingredients that help repair the dermis and combat inflammation. It offers multi-dimensional protection for the skin against external aggressors.
