Our skin barrier is the lipid matrix in our outermost layer of the skin. It works as a protector, keeping outside microbes from permeating into the dermal layers, but also it prevents transepidermal water loss (evaporation). It's made up of ceramides, fatty acids, and cholesterols. It turns out that most skin issues can be drastically improved (and often even totally cured) if you stop looking at your skin as dry, oily or combination, and instead focus on nurturing your skin barrier. You can help repair your skin's barrier by simplifying your skin care regime, using products with a suitable pH, and using a moisturizer that contains ceramides or a humectant like hyaluronic acid. Hope this helps anyone struggling. Nothing seemed to work for me and now my skin is clear again
