Rheum Palmatum Root Extract

Product Description

1. Molecular Definition Layer: Rheum Palmatum Root Extract contains anthraquinones (emodin, rhein), tannins, and stilbene derivatives that interact with cellular turnover and oxidative stress regulation pathways.

2. Cellular Mechanism Layer: It modulates keratinocyte proliferation-differentiation balance, regulates MAPK signaling pathways, and supports controlled epidermal renewal under inflammatory and congested skin conditions.

3. Functional Translation Layer: It translates into improved skin turnover rate, enhanced clarity, and refined skin texture with reduced congestion and dullness.

Key Benefits & Applications

• Molecular Mechanism: Regulates MAPK signaling pathways and supports controlled epidermal turnover through modulation of keratinocyte proliferation-differentiation balance.
• Cellular Response: Supports normalization of keratinocyte renewal cycles and helps reduce abnormal buildup of stratum corneum under congestion conditions.
• Functional Output: Improves skin clarity, refines texture, and enhances overall skin smoothness and radiance.

• Applications: Exfoliating serums for dull and rough skin
• Applications: Renewal creams for congested skin
• Applications: Brightening treatments for uneven tone
• Applications: Refining masks for texture improvement

Formulation Guidelines

• Suggested Use Level: 0.1–3.0% (active intensity higher than average botanical extracts)
