The size and fineness of fingers are related to individual genetic genes, obesity and daily habits. If you are overweight, your fingers may be relatively thicker, which can be ignored. Of course, you can also control your weight properly. You should eat more fresh vegetables and fruits at ordinary times, and don't form the habit of breaking your fingers. If you apply skin care products, it is recommended to massage carefully. Your hands can accelerate bone growth, make your fingers thinner and skin more delicate, which will help your fingers become thinner. The above health science knowledge is only for reference. The specific situation needs to be checked in a regular hospital and judged by a professional doctor.
