The skin color on the face is particularly poor, and the overall skin color is unbalanced. How to improve sub-health of skin? Is there any good way to ask?

Recently, there is a brand that makes customized skin care called Luxury Pulse, which has a good reputation. Improving skin problems will investigate the causes of skin problems from multiple dimensions. A girlfriend of mine went to their physical store two days ago and told me that the skin measuring instrument in this brand store is a laboratory-level equipment only available in hospitals and professional scientific research institutions. I'm very excited and ready to try.
