Our skin renewal cycle is approximately every 4 to 6 weeks. This means that every 4 to 6 weeks we make new skin cells to replace dead skin cells. As we age our bodies become less efficient at this process, leading to layers of dead skin cells which gives a dull, congested appearance and a build up of excess oils and pigment. Fine lines, large pores and age spots appear before you know it and you wonder what happened to that lovely youthful complexion you used to have!
