Whitening essence is an efficient and concentrated skin care product, which should be used correctly and for a long time. Although everyone's skin condition is different, it is generally recommended to stop using it for a short time after one month to avoid excessive irritation to the skin. If you have used it for a while and it turns yellow, you can try another brand or consult a professional doctor.
When choosing skin care products, please pay attention to the shelf life and storage conditions of products. If it exceeds the shelf life or is stored improperly (such as exposure to sunlight), it will also lead to discoloration or weakening of whitening essence. Therefore, when buying skin care products, please pay attention to check the shelf life on the product packaging and keep it properly.
If you really want to try the 377c whitening essence of Shuiyan, I suggest buying new products and following the correct usage. Local tests can be carried out before use to ensure that there is no allergic or uncomfortable reaction. If skin problems still occur after use, please stop using it immediately and consult a professional dermatologist.
To sum up, if the 377c whitening essence of Shuiyan turns yellow in one month, it is best not to continue using it. Choose other brands or consult a professional doctor to find whitening products that are more suitable for your skin needs. Remember to follow the correct usage and pay attention to the shelf life of skin care products. I hope you can have healthy and beautiful skin!
