types of Acne

No matter how modest you are, your epidermis is always showing. It’s the top layer of your skin, the one you show to the world — and like your other organs, it has to work constantly to keep you alive. The very top layer is actually made up of dead cells, or corneocytes. This outer layer acts as your body’s natural suit of armor, protecting you from the sun, wind and rain. As your skin renews itself, the dead cells gradually slough off to make room for new ones, which are forming at the base of the epidermis. Once the new cells are ready, they begin to travel up through the epidermal layer, where they gradually replace the dead cells. If you followed the progress of one cell, the whole process would take about a month. But it’s happening constantly — in fact, in the time it took you to read this, you’ve probably lost about 40,000 cells. Luckily, 95% of your epidermis is working to create new cells. The other 5% are composed of melanocytes, which produce melanin, the substance that gives your skin its color; and Langerhan cells, which work with the immune system to help you fight off disease.
