Recent studies show that lactic acid can support the "good" bacteria living on skin's surface (healthy skin microbiome)
Moisturizing

An oil that is naturally part of skin sebum that helps to soften its upper layer, reduce water loss and neutralize free radicals. It might be comedogenic. Avoid applying large concentrations (or pure oil) before sun exposure as oxidized squalene can clog pores and lead to skin irritation. Today squalene is mostly derived from vegetable oils or synthetized by yeast
