Silymarin Milk Thistle Extract Oil-Soluble Antioxidant Anti-Inflammatory Brightening Anti-Photoaging Cosmetic Raw Material(CAS 22888-70-0)
Silymarin is a high-efficiency natural plant-derived dual-phase antioxidant and anti-photoaging active extract. Breaking the limitation of traditional single water-phase antioxidants, it has unique oil-water dual-soluble antioxidant activity, which can comprehensively scavenge free radicals in both lipid and aqueous skin layers.
It specifically solves the core skin pain points of oily skin lipid oxidation, yellow dullness and UV-induced photodamage aging.
It can effectively resist ultraviolet radiation, reduce sunburn erythema and inflammatory redness, inhibit photo-induced pigmentation, and repair rough and dull light-aged skin texture.
As a mild and safe plant anti-aging factor, it realizes multi-dimensional skin care effects of anti-oxidation, anti-photoaging, anti-inflammation and brightening without irritating fragile skin. It is an indispensable core upgraded plant raw material for oily skin brightening maintenance, sun damage repair and high-efficiency anti-light aging formulas.
Key Benefits
• Water-Oil Dual-Phase Anti-Oxidation, Full-Dimensional Anti-Aging: Different from single-function antioxidants, silymarin acts on both water phase and oil phase of the skin, comprehensively scavenges various free radicals, inhibits lipid peroxidation, cuts off the skin aging chain from the source, and solves the aging problem that traditional antioxidants cannot cover.
• Targeted Anti-Grease Oxidation, Improve Oily Yellow Dullness: Specialized in solving the pain point of oily skin oxidation and yellowing, effectively resist sebum oxidation and dull precipitation, improve long-term greasy, yellowish and dull skin tone, restore skin translucent and clean texture, and create non-greasy brightening skin state.
• Professional UV Photoprotection, Efficient Anti-Photoaging: Form an invisible ultraviolet defensive barrier on the skin surface, reduce UV penetration damage, relieve sunburn redness, swelling and peeling, inhibit photo-induced pigmentation and light wrinkle formation, and delay skin light aging progress.
• Mild Anti-Inflammatory Soothing, Repair Sun Damaged Skin: Effectively inhibit the release of inflammatory factors caused by ultraviolet stimulation, calm acute sun sensitivity, redness and burning sensation, reduce skin fragility after photodamage, and quickly repair stressed skin state.
• Pure Plant Source & Ultra-Mild, Safe For Long-Term Use: Extracted from natural milk thistle seeds, pure plant active ingredients, zero irritation, zero sensitization, no hormone dependence. Safe for oily skin, sensitive skin and sun-exposed fragile skin, suitable for daily long-term anti-oxidation maintenance.
• High Activity & Stable Formula, Strong Synergistic Effect: Stable active components, not easy to inactivate in oil phase and emulsified systems. It can form a super anti-oxidation combination with ferulic acid, VC and VE derivatives, significantly enhance the full anti-aging efficacy of the formula, and improve product market competitiveness.
Applications
• Oily Skin Anti-Oxidation Brightening Series: Core targeted active for oily and combination skin, improving sebum oxidation, yellow dullness and greasy dark complexion.
• Anti-Photoaging & UV Protection Products: Exclusive plant anti-light aging raw material, resisting UV photodamage, delaying skin light aging and smoothing light-induced fine lines.
• Post-Sun Repair Soothing Formulas: First-choice soothing repair active for sun-exposed skin, calming sunburn redness, heat sensation and inflammatory sensitivity.
• Dull Yellow Skin Translucent Brightening Essence: Professional anti-oxidation and yellow-removing active for sallow and dull skin, brightening complexion and enhancing skin translucency.
• Sensitive Skin Anti-Inflammatory Stabilization Series: Mild plant soothing factor for light-damaged sensitive skin, reducing inflammatory flushing and stabilizing fragile skin state.
• High-End Compound Anti-Oxidation System: Perfectly compatible with ferulic acid, vitamin C/E derivatives and various soothing extracts, building a closed-loop system of "dual-phase anti-oxidation + UV protection + anti-inflammation + brightening".

Frequently Asked Questions (FAQ)
• Q1: What is the MOQ of Silymarin?
A1: The standard MOQ is 25KG, support sample orders for formula testing, anti-oxidation brightening and anti-photoaging efficacy debugging and finished product trial production, and support customized purity specifications for mass production.
• Q2: What is the core formula positioning of Silymarin?
A2: It is a high-purity natural plant extract integrating water-oil dual-phase anti-oxidation, anti-photoaging, anti-inflammatory soothing and dullness brightening. It focuses on solving oily skin oxidation yellowing and UV photodamage aging problems, and is used for high-end oil-control anti-oxidation and anti-light aging formula upgrading.
• Q3: What is the recommended dosage in cosmetic formulas?
A3: Conventional anti-oxidation maintenance: 0.05%–0.2%; Oily skin brightening anti-yellow series: 0.1%–0.5%; Post-sun repair soothing formulas: 0.2%–0.8%; High-efficiency anti-photoaging products: 0.5%–1.0%, adjustable according to product efficacy positioning and oil-water formula system.
• Q4: What are the advantages of Silymarin over ordinary antioxidant ingredients?
A4: Ordinary antioxidants such as VC and VE only have single water-phase or oil-phase antioxidant capacity, with limited anti-aging coverage. Silymarin has unique water-oil dual-phase anti-oxidation activity, specially targets sebum oxidation and yellow dullness, and has additional anti-photoaging and anti-inflammatory repair efficacy, with more comprehensive and stable efficacy and stronger formula synergy.

The compound system can form a closed-loop efficacy system of "dual-phase anti-oxidation + UV protection + inflammatory stabilization + translucent brightening", greatly improving the full-dimensional anti-aging and brightening competitiveness of finished products.
• Q6: What are the formula usage notes?
A6: Oil-soluble plant powder, recommended to pre-dissolve in oil phase or ethanol first; suitable for weak acid and neutral formula systems; recommended feeding temperature 40–65℃, avoid long-term high temperature above 75℃ to prevent active inactivation; finished products should be sealed and stored away from light to ensure stable anti-oxidation and anti-photoaging efficacy, suitable for industrial mass production.
• Q7: Can it provide stable supply and professional technical support?
A7: Strictly control core indicators such as extract purity, moisture, ash content and heavy metals to ensure consistent batch stability. Support long-term bulk order supply, and provide one-stop professional services including oily skin anti-oxidation formula optimization, anti-photoaging efficacy upgrading, formula debugging and after-sales technical guidance.
