Skin Genetics: What Your Family History Could Mean For Your Skin

Your skin is affected by numerous external factors, such as your environment or your skin care routine. Underneath the surface, your skin is affected by a more permanent factor: your genes.

Genes, are what make you, you. They are made up of DNA, which determines what you will inherit from your family members. DNA does this by telling your cells how to make proteins that create all the structures and functions in your body. You have an estimated 20,000 to 25,000 different genes.

With inheriting your dimples, curly hair or blue eyes, skin problems can also be inherited. This is collectively called genodermatoses, or genetic dermatological disorders.

Genes have a significant influence on skin because skin is made of so many proteins. The main structure of the skin is created by collagen, which is a protein. It provides strength and stability, and as you age the collagen strength decreases, which is why sagging and wrinkles develop over the years. Melanin is another type of protein, which is responsible for giving your skin its color.

Genetic factors are hereditary, which means if your parents had or have a certain trait or condition, there’s a good chance you’re going to develop it as well and carry it onto the next generation.
