We shed a lot skin, constantly. In fact, your skin seems to completely renew itself every 30 days or so (ideally). Why? Because you skin there to protect the rest of your body – it is designed to grow quickly from the deepest layers through to the uppermost, so that it can shed. This process allows your skin to keep impurities out of your body.
Your skin has to fend off a barrage of attacks from pollutants, chemical, ultra violet rays, climate, bacteria and a host of potential infections and your skin is there to save the day. Fending off these elements has an impact on your skin.
This “impact” (damage) can show up in a few ways, from wrinkles, lines and sagging to hyper-pigmentation and even acne.
