Purpose of Testing for Serum:
The purpose of testing a serum is to ensure its safety, stability, and efficacy for targeted skincare use. Key testing objectives include:

• Efficacy Testing – to validate claims such as anti-aging, brightening, or hydration through clinical or instrumental studies

• Dermal Safety – to assess irritation, sensitization, or allergic reactions via patch and use tests

• Microbiological Testing – to confirm the product is free from harmful microbial contamination

• Stability Testing – to evaluate how the serum performs over time and under different environmental conditions

• Active Ingredient Potency – to ensure the concentration and integrity of key actives are maintained throughout shelf life

These tests ensure that the serum is safe, effective, and meets quality standards for consumer use.
