|Increase ceramide production in your skin with yogurt.|
You can improve all these things by applying plain live-culture yogurt to your skin topically. A study found an increase in ceramide production and reduction in inflammation after 7 days of topical use yogurt. And a reduction in acne. Some strains of the beneficial bacteria also secrete peptides, another thing you've no doubt seen on your moisturizer bottle. And then moisturize with plant oils such as safflower, grapeseed or hemp seed to make up for the loss of the lipid barrier.
