Your skin is made up of many cells and layers of tissue. The uppermost layer of the skin is known as the Epidermis. The cells in your skin renew themselves, or shed, every 28-30 days. This process is known as cellular turnover. Once the cells shed they are replaced with fresh, new, younger, healthier cells. Cells start out plump and full of moisture and as they age they rise through the layers of skin and become more flat and dry until they reach the surface. How quickly your cells age has to do with several factors including your age, environmental exposure, hormones, food that you eat, and if you smoke. Babies cell turnover happens every 2 weeks, which explains their super soft and smooth skin. By our teenage years it takes about 3-4 weeks for the turnover process. By our 40's, it can take as long as 45 days for the cellular turnover process to complete, and in our 50’s it’s about 60 days. The longer the cell turnover cycle takes the more dead cells are left to buildup on the surface of the skin, making it appear heavy and dull. The dead cells clog and stretch pores making them appear larger and more pronounced, oil and bacteria become trapped which can lead to breakouts. Wrinkles appear deeper as dead cells build up around them and pigmentation appear darker. By increasing cellular turnover you remove dead skin that accumulates on the surface and reduce the appearance of pores. Exfoliation is the key to boosting skin turnover. Exfoliation removes dead skin cells and encourages the generation of new cells. Chemical (acid) or physical (scrub) are both great forms of exfoliation. Exfoliating twice weekly is key to smooth and clear skin. Vitamin A is also another great way to increase cellular turnover. Vitamin A (Retinol) works to speed the process of cell turnover but it also acts as a cell regulator, signaling the production of collagen and elastin.
