Science
Mechanism of Action
Poria Cocos Extract significantly boosts skin's intrinsic hydration by leveraging β-glucans and polysaccharides to enhance water retention and fortify the lipid barrier, thereby minimizing transepidermal water loss. Its unique triterpenoids and fungal polysaccharides demonstrate potent anti-inflammatory effects by inhibiting nitric oxide production (by approximately 60.3-60.4% in water extracts), effectively soothing irritation and reducing redness. Furthermore, this extract modulates sebum production, making it beneficial for achieving skin balance. It delivers robust antioxidant protection against environmental aggressors, while its triterpenoids support collagen integrity and stimulate the production of both collagen and hyaluronic acid, leading to improved skin elasticity and firmness. The extract's capacity to reduce elastase activity (by 96.7-98.3%) and collagenase activity (by 60.0-72.2%), alongside its proliferative effect on integrins, contributes to a visible tightening effect, addressing skin sagging and deep wrinkles. Additionally, it promotes a more uniform complexion through gentle exfoliation, tyrosinase inhibition, and reduction in melanin synthesis, complemented by its broad-spectrum antibacterial and antifungal properties.

Key findings
- 01 Demonstrated significant elastase inhibitory activity (96.7% and 98.3%) and collagenase inhibitory activity (60.0% and 72.2%), indicating anti-aging effects.
- 02 Showed superior anti-inflammatory effect through Nitric Oxide production inhibitory activity (60.4% and 60.3%).
- 03 A fermented extract of Poria cocos sclerotium is preferably used in topical compositions within this range, with 15-35% being more preferred and 20-30% most preferred.
- 04 Specific Poria cocos lanostane triterpenoid compounds enhanced type I collagen expression in human dermal fibroblasts.
Transparency
Dusting Analysis
Given that a fermented Poria Cocos extract is suggested for use in topical formulations at substantial concentrations (up to 40%, with 20-30% being most preferred), it is unlikely to be utilized merely for 'dusting' at sub-efficacious levels.

Formulation
Stability
The polysaccharide structures within Poria Cocos Extract are susceptible to degradation in alkaline conditions and at high temperatures. Its slight hygroscopic nature during handling necessitates careful storage to maintain stability.
Conflicts
- strong oxidizers
- nitric acid
- alkaline environments
- high temperatures
Safety
Safety Profile
Poria Cocos Extract is generally considered safe and well-tolerated by most skin types, including sensitive skin, exhibiting a low risk of irritation. It has not been formally reviewed by the CIR or SCCS for cosmetic use. While the FDA does not pre-approve individual cosmetic ingredients, its use in cosmetics aligns with general regulatory guidelines. It is important to differentiate Poria Cocos, a fungal extract, from Cocos Nucifera (coconut) to prevent misidentification.
