Dermis – This layer gives your skin its elasticity and is made up of collagen and blood vessels. This layer also contains your oil ducts and hair follicles. This is why if the dermis is damaged, your hair won’t grow back.
Any damage up to the dermis (partial thickness wound) can easily be regenerated by your body! It’s when wounds are deeper (full thickness wound) that things get more challenging.
Effects of aging on your skin: The dead skin cells of your epidermis are constantly falling off and getting replaced by new cells from below. This process takes longer as we age, and it is why older people have thinner skin and wrinkles!
- The first 2-3 weeks of life: Skin is very thin and extremely absorptive
- Young Adults: Takes three weeks for base layer of epidermis to fully replace top
- By Age 35: Takes twice as long to replace, or six weeks
- By age 60: Cell replacement slows and the skin becomes thin and dry
