A good skincare routine is essential for maintaining healthy looking, fresh skin. To many people, getting a facial is a treat, something they do once in a while to freshen up their skin. Getting a facial every 4 to 6 weeks is a great supplement to your skincare routine. Just like any skincare regimen, facial treatments are best when done consistently and regularly. The reason behind getting monthly facials is that your stratum corneum (outermost layer of visible skin ) will completely renew itself approximately every 28 days. In this time your cells are constantly being replicated from the treated cells to replace old ones.
