Can anyone objectively say that the products developed by Yan 'antang are reliable?

Recently, I started with his glycerin water-oil conditioning mask and said two personal opinions.

You can't say that it is comparable to thousands of ladies' skin care products such as sk2 and CPB, but it is definitely one of the best in the same price. Their R&D teams are all from big companies such as Estee Lauder, Procter & Gamble and Unilever. They can collect the needs and feedback of a large number of users, and then combine their own scientific advantages to develop products. The ingredients used are also very careful, and there are no miscellaneous things added, which makes passers-by like me feel quite reliable.
