We can look at the product composition. Lutein is a natural nutrient in plants, which has antioxidant and eye health protection effects. Normally, lutein is safe, but if it exceeds the recommended intake, it may cause some side effects. Therefore, when using lutein products, we need to take it according to the recommended dosage in the instructions to avoid unnecessary risks.
We can consider product quality control. Lutein, as a product endorsed by top athletes, must undergo strict quality inspection and control. As a spokesperson, ZhangJike will also review and confirm the safety of products. Manufacturers will also pass various certifications to prove the quality and safety of products. So from this perspective, lutein endorsed by ZhangJike should be safe and reliable.
Third, we can observe consumers' feedback on products. According to the recommendation and praise of skin care magazines, the essence of ocean wisdom time is a favorite product of consumers. This means that many people have no safety problems during use and are very satisfied with the effect and quality of the products. This is also an important basis for evaluating product safety from the perspective of consumers.
