Photostability Testing

Overview

When we go outside, our bodies are exposed to the sun and its UV rays, and we have learned how UV rays can cause significant damage to our bodies. Cosmetics and packaging can also be damaged by UV rays. Exposure to light can significantly alter formulations and cause degradation of product ingredients and unpleasant changes in packaging. When products are displayed on shelves for sale, they may be exposed to prolonged lighting, which can affect the color, odor, and overall appearance of the product. Cosmetics whose packaging allows the product to be exposed to light should be tested for light stability. Light stability testing includes products in actual packaging and products in glass, placed as controls under a controlled light source with broad-spectrum output to account for the lighting variations they may encounter. Samples are compared to samples of products not exposed to light to determine if significant changes caused by illumination have occurred.

Specific Services We Offer

• UV Exposure Testing

We subject your cosmetics to controlled UV exposure to simulate real-world conditions. This testing evaluates the product's adaptability to UV radiation and helps you understand its stability and potential for fading or degradation.

• Accelerated Aging Studies

By utilizing accelerated aging techniques, we can determine how your cosmetics will hold up over a longer period of time. This testing allows us to predict long-term stability and ensure that your product retains its desired properties when exposed to light.

• Color Fastness Assessment

We evaluate the color fastness of your cosmetics to determine if they will retain their desired color without fading or changing dramatically when exposed to light. This assessment helps ensure the visual appeal and consumer satisfaction of your products.

• Efficacy Assessment

We analyze the effect of light exposure on the efficacy of your cosmetic formulations. This testing helps determine if there are any noticeable changes in performance, such as UV protection, moisturizing properties, or anti-aging effects.
