Skin Soothing Test

Cosmetics protect the skin from external aggressors to reduce irritation and redness. They have a soothing or calming effect and make the skin look healthier.

Protheragen-ING recognizes the importance of soothing and calming effects in cosmetics. Our Cosmetic Soothing Efficacy Testing Service aims to provide valuable insights by assessing the effectiveness of various cosmetic products in soothing and comforting the skin.

Protheragen-ING's Testing Services

We tailor testing protocols to specific needs, such as comparative testing, long-term efficacy studies, or sensitivity testing in specific populations.

The testing service will analyze samples for their active ingredients and formulations and conduct in vitro testing to understand their potential soothing properties and identify any potential irritants or allergens.

We use cutting-edge technology to obtain objective measurements to evaluate the soothing benefits of cosmetic products, including assessing skin redness, inflammation, irritation, and hydration levels. Subjective factors, such as participant comfort, are also taken into consideration.

We have a variety of molecular biology techniques at our disposal for in-depth analyses, such as Western blotting, enzyme-linked immunosorbent assay (ELISA), and enzymatic assays.

Once the testing phase is complete, we will provide a comprehensive report summarizing the findings.

Product Evaluation Method

This test method is used to evaluate the soothing and sedative efficacy of test samples at different evaluation intervals, focusing on the product's ability to reduce redness and improve skin smoothness.

Measurements were performed in a dark room. Baseline, one hour, two hours, or four hours following use are among the time intervals.

Melanin and hemoglobin (erythema), the two main pigments that determine skin tone, are measured using equipment based on the absorption and reflection of two particular wavelengths.

Calculating the amount of light absorbed by the skin is possible once the amount of light emitted is known. Calculate the average by taking several readings. It is possible to quantify the calming and energizing effects.
