Verify efficacy with science and define skin beauty with data.

Efficacy Validation

1. In Vitro Bioactivity Tests

• Based on a variety of human cell models (such as HaCaT keratinocytes, HDF human skin fibroblasts, B16 melanocytes, etc.).

• Verify antioxidant capacity (ROS removal), collagen production, tyrosinase inhibition, inflammatory factor regulation and other functions.

• Use ELISA, RT-PCR, flow cytometry and other methods for accurate quantification.

At NatureXcel™ Scientific, we are fully aware that every raw material carries scientific responsibility and skin care trust. Therefore, we provide systematic and detailed efficacy verification data for each functional raw material to support customers in the entire process of formula development, regulatory filing and marketing.

2. Pre-clinical Efficacy Assessment

• Evaluate the structure and physiological response in human skin reconstruction models or organoids (3D skin models)

• Including key indicators such as stratum corneum thickness, epidermal integrity, cell viability, elastin expression, etc.

• Some raw materials provide volunteers with before and after image comparison and skin quality data change trend

3. Skin Microbiome Modulation

• Applicable to female intimate care raw

• materialsTest the effect on vaginal natural lactic acid bacteria (such as Lactobacillus)

• Test pH stability, biofilm generation inhibition, microbial community diversity regulation and other dimensions

• Provide scientific basis for the concept of symbiotic microecology in line with the human body

4. Sebum & Skin Barrier Repair

• Use squalene model and sebum membrane simulation system to evaluate the ability to improve sebum metabolism

• Provide TEWL (transepidermal water loss) test, stratum corneum integrity assessment, ceramide expression data

• Can be combined with skin electrical impedance test (Impedance), infrared imaging and other means to quantify skin care results

5. Multidimensional Efficacy Profiles

• For different efficacy types (antioxidant, whitening, firming, sun protection, etc.)

• Provide heatmaps/radar maps to display the efficacy strength of each dimension

• Data sources include in vitro tests, pre-clinical tests and literature support, which facilitates brand positioning and formula main ingredient construction

• Press briefs, English technical documents, and regulatory summaries can be customized according to customer needs

• If you need more specific test reports, charts or customized technical documents for raw material selection or promotion, we can provide one-on-one support.

• NatureXcel™ Scientific is not only a raw material provider, but also a scientific research partner you can trust

6. One-on-One Support.
