Science
Mechanism of Action
This extract operates by modulating immune responses and suppressing inflammatory pathways. It has been shown to reduce key proinflammatory cytokines, including TNF-α, IL-4, IL-6, and IFN-γ, while also decreasing mast cell presence and immune cell infiltration. Pinus Koraiensis Cone Extract supports dermal structural integrity by increasing filaggrin mRNA expression and decreasing IgE levels. Its anti-inflammatory action also involves reducing lipid peroxides and inhibiting iNOS and COX-2 activity, thereby lowering PGE2 and IL-1β production. Furthermore, it exhibits antioxidant activity, promotes collagen synthesis, inhibits MMP-1, and may suppress melanin production, contributing to anti-aging benefits and improved skin tone.

Key findings
- 01 Topical application of a 30% butylene glycol extract of Pinus koraiensis cone extract significantly alleviated clinical atopic dermatitis symptoms in AD-induced mice, including reduced erythema, edema, excoriation, and itching. This was accompanied by increased filaggrin mRNA expression and reduced IgE content in the skin.
- 02 In vitro studies (at 25 µg/mL) demonstrated anti-inflammatory activity, with Pinus koraiensis cone bark extracts inhibiting COX-2 expression by 50% and IL-1β production by up to 50% relative to controls.
- 03 Cosmetic compositions containing this extract, particularly within a range of 0.01% to 10%, have shown multiple skin improvements, including enhanced collagen biosynthesis, inhibition of MMP-1 production, suppression of melanin production, reduced inflammatory cytokine expression, antioxidant effects, and improvements in skin wrinkles and elasticity.
Transparency
Dusting Analysis
Effective concentrations for general skin improvement are reported from 0.01% to 10%, with targeted atopic dermatitis relief shown at 30%. These percentages indicate it is utilized at functional levels, suggesting it is not commonly 'dusted' for marketing claims.
The Formula
Formulation
Stability
This extract can be prepared using a wide range of polar and non-polar solvents, including water, lower alcohols, acetone, and various esters and hydrocarbons, indicating its components have diverse solubilities. It generally exhibits good stability, with related pine cone extracts showing high stability in emulsion systems. However, concentrations exceeding 30.0% by weight may compromise formulation safety and stability.
Safety
Safety Profile
Specific safety reviews by CIR, SCCS, or FDA for cosmetic use are currently unavailable. In an in vitro study, Pinus koraiensis cone bark extracts at concentrations of 25-50 µg/mL significantly reduced cell viability, indicating potential cytotoxicity at higher in vitro concentrations, though this specific dose does not directly translate to cosmetic application percentages. A related patent suggests that concentrations exceeding 30.0% by weight might lead to problems with formulation safety and stability.
