Manuka honey
While you may not have heard of this particular kind of honey, you’ve likely crossed its path in natural skin care products, as it boosts cytokine production which in turn fights off pathogens and protects you from infections. When it’s applied to your skin directly (or even just consumed along with coffee or tea), this kind of honey rejuvenates skin and boosts immunity to harmful pollutants in the air, according to Hayim.
