As we age, our skin loses collagen, elastin and other factors which contribute to fine lines appearing. Just like a bed sheet that is constantly folded, a crease will appear when the muscles under the skin are constantly contracting and creating lines on our face.
There are many factors that can create wrinkles however sun damage is the number 1 cause for premature ageing. Other factors include genetics, diet, smoking, lifestyle/stress and dehydration. We create wrinkles when we make an expression, like a smile or squinting will make crows feet visible as an angry face will make frown lines. After expression some lines will disappear however others will become “static” and are visible signs of ageing.
