First of all, this article is suitable for ladies over 17 years old. Girls under 17 years old do not need detailed skin care if they do not have acne problems. They only need to do basic cleaning, moisturizing and sun protection. Many people say bad things about skin care, but finding a skin care method that suits you is an arduous and tortuous road. There are many online experts, but experts are not omnipotent. If there are professional vocabulary in the article, I will try my best to explain it in detail. After all, some professional vocabulary about skin care is not known by Baidu. Also, I don't recommend any of the products. Welcome to ask questions.
