Evaluating the efficacy and safety of cosmetics is a comprehensive process that involves multiple considerations. The following are the main aspects of the efficacy and safety evaluation of cosmetics:
Efficacy assessment
Moisturizing effect: Evaluates whether the product can effectively lock in moisture and provide long-lasting moisturizing effect.
Sun protection efficacy: Test the sun protection index of a product and evaluate its ability to block ultraviolet rays.
Whitening effect: Through the measurement of **color, evaluate whether the product can effectively reduce melanin and brighten the skin tone.
Anti-wrinkle effect: Observe whether the product can improve the elasticity and firmness of ** and reduce the formation of wrinkles.

In addition, the safety assessment of cosmetics also needs to consider the raw materials of the product and possible risk substances, including the toxicity, carcinogenicity, allergenicity and other aspects of the raw materials. During the evaluation process, methods such as calculating the safety margin, lifetime carcinogenic risk (LCR), and comparison of acceptable exposure levels with actual exposures can be used to comprehensively evaluate the safety of the product.
