A personal care composition includes an ozone-stressed yeast lysate; and a preservative, in which the preservative is selected from phenoxyethanol, isopropyl alcohol, benzyl alcohol, propylene glycol, butylene glycol, pentylene glycol, methylparaben, propylparaben, butylparaben, benzalkonium chloride, Quaternium 15, methylisothiazolinone, methylchloroisothiazolinone, DMDM hydantoin, imidazolidinyl urea, diazolidinyl urea, butylated hydroxytoluene, tocopherol, triclosan, chlorohexidine digluconate, and combinations thereof, and the ozone-stressed yeast lysate is produced by a method including exposing growing yeast to ozone by aerating the yeast for a time period of between five minutes and seventy-two hours with an aeration gas having an ozone concentration of from 0.0001 millimolar (mM) to 1.0 millimolar (mM) based on the total volume of the fermentation broth to produce ozone-stressed yeast lysing the ozone-stressed yeast to produce an ozone-stressed yeast lysate comprising water-soluble and water-insoluble components; and separating the water-soluble components from the water-insoluble components to produce an ozone-stressed yeast lysate containing the water-soluble components.
