If you buy her a set, generally speaking, a set of mid-range cosmetics is almost no less than 500, because a set includes a lot: facial cleanser, water, lotion, essence, cream, cream, eye cream, and generally does not help the poor. The effect on dark yellow skin is not obvious, and a set can not be improved. Dark yellow skin is more caused by internal reasons of the body, and it is of little use to rely solely on skin care.
As for eye cream, the effect is both visible and relatively affordable.
If you feel that you don't like face, add a box of Yangshengtang vitamin E, which is specially used for freckle removal and beauty, improving dark yellow skin and conditioning from the inside. Generally, people over 25 can eat one tablet a day. You can see the effect every month or so. I am 2 years old. After each month, the sunburn on the face as big as a grain of rice becomes very light, and the skin around the eyes is not so dark.
All the above are my own personal experiences, and I hope I can help you!
