Selaginella Extract

Harvested from the drought‑resistant resurrection plant Selaginella tamariscina, our Selaginella Extract is a premium botanical raw material concentrated with biflavonoid complexes, with amentoflavone acting as the signature bioactive marker. Unlike ordinary plant‑derived antioxidants, this extract delivers outstanding radical‑neutralizing potency, supporting skin cellular resilience against UV‑triggered photo‑damage, environmental pollutants and internal oxidative stress.

Rich in polyphenolic biflavonoids, the material modulates key skin‑relevant gene pathways including SIRT1 expression, helping sustain keratinocyte activity and reinforce epidermal structural integrity. It exerts gentle anti‑redness and bacteriostatic effects without harsh irritation triggers, making it well‑suited for high‑end anti‑aging skincare, sensitive‑calming formulas, post‑procedure repair products and select nutraceutical blends.

Our production applies controlled low‑temperature solvent extraction plus HPLC‑guided fraction purification to preserve thermolabile active biflavonoids. Every batch passes multi‑layer safety and contaminant screening, aligning with global cosmetic regulatory frameworks for cross‑border brand formulators.

• Advanced Anti‑Photoaging Antioxidant Agent Neutralize reactive oxygen species and lipid peroxide buildup caused by sun exposure and external aggressors. Mitigate matrix protein degradation, slow visible photo‑aging signs including dullness and rough texture for long‑term skin youth preservation.
• Soothing & Anti‑Redness Functional Component Regulate inflammatory mediator release, ease transient skin irritations, calm flushed and reactive complexion. Restores comfortable skin state for sensitivity‑targeted skincare and post‑aesthetic care lines.
• Skin Barrier Reinforcement Ingredient Elevate keratinocyte vitality and support SIRT1 longevity‑related gene activation, reducing transepidermal water loss. Improve dry, fragile skin condition and strengthen natural skin defense barrier.
• Acne‑Prone Skin‑Friendly Additive Exerts mild bacteriostatic property, non‑comedogenic formula compatibility, helps optimize skin surface micro‑environment for oil‑control and blemish‑care cosmetic series.
• Dietary Supplement Raw Material Qualified for select health supplement formulations focused on antioxidant maintenance (please conduct finished‑product safety validation before commercial launch).

Q1: What is the core working mechanism of Selaginella Extract for skin care?

A: Its primary marker amentoflavone belongs to biflavonoid compounds. It scavenges free radicals, modulates SIRT1 gene expression and inhibits pro‑inflammatory signaling pathways, combining antioxidant, soothing and barrier‑strengthening multi‑effects for skin cells.

Q2: What is the recommended adding percentage for cosmetic finished formulas?

A: Typical recommended addition range is 0.5%‑3.0% in finished cosmetic products. Actual dosage needs fine‑tuning based on product type, target efficacy and formula solvent system. Our technical team can provide further formulation guidance.

Q3: Is Selaginella Extract safe for sensitive and damaged barrier skin formulas?

A: Safety test results show non‑irritating to intact and abraded skin, non‑sensitizing and non‑phototoxic. It is widely adopted for sensitive‑calming and post‑procedure skincare lines. Pre‑formula patch test is still suggested for your specific finished‑product system.

Q4: Does this ingredient comply with global cosmetic regulatory requirements?

A: It complies with EU EC 1223/2009 cosmetic regulation, FDA cosmetic guidance and China GB 7916 cosmetic safety standard, and is recorded in China 2021 Cosmetic Ingredient Catalogue (No.04062). We provide complete supporting documents for your filing.

Q5: What solvents can Selaginella Extract dissolve in? Any formulation limitation?

A: It presents better solubility in alcohol‑water mixed systems. Pure‑aqueous formulas may show partial precipitation; you may need co‑solvent or solubilizer adjustment. Contact our technical team for compatibility advice.

Q6: What is your MOQ for Selaginella Extract? Can I get free samples?

A: Standard MOQ is 1kg. Small lab‑test samples are available upon request; freight cost may be covered by buyer. Reach our sales team to apply for sample service.

Q7: How should I store opened bags of Selaginella Extract powder?

A: After opening, squeeze out air and seal tightly. Keep stored in cool, dry, shaded and ventilated location. Avoid frequent temperature fluctuation and high‑humidity environment to prevent active‑component degradation.

Q8: What shipping options can I select for bulk orders?

A: Express courier for small‑volume orders under 100kg; air freight for 100‑1000kg cargo; sea freight for heavy bulk above 300kg. Different transit time and customs‑handling requirements apply for each logistics method.
