The mustard plant makes a condiment that is more likely to end up on your sandwich than on your face. But mustard seeds -- commonly distilled into an oil or crushed into a powder -- actually offer skin-friendly fats and proteins. Although no definitive proof that mustard fights acne exists, it is true that mustard contains potentially anti-inflammatory sinigrin and antioxidants -- which may reduce inflammation by curbing oxidative stress. You won't find mustard in store-bought skin products, however, so you'll have to get a little creative at home to fight acne with mustard.

Pour turmeric powder into a small mixing bowl -- a spoonful or two should do the trick. Use enough to make a paste that will cover existing pimples. Turmeric powder contains curcumin, which fights the inflammatory, acne-causing bacteria of the Propionibacterium species.

Add a few drops of mustard oil and pure lemon juice to the turmeric powder. Lemon juice acts as an oil-reducing astringent, while mustard oil combats bacteria and helps to keep the skin supple with its plentiful fatty acid and omega-3 content. Stir the mustard oil, lemon juice and turmeric powder with your fingertip until the mixture takes on a paste-like consistency.

Wash and dry your face as usual, then apply the paste to pimples. Allow it to rest for about 15 minutes, then wash it away with plain water. Repeat the process two to three times weekly.

Measure enough mustard powder to cover your pimples into a small mixing bowl.

Combine the mustard powder with pure honey to make a thick paste. Honey has naturally antimicrobial properties, which may help combat the pore-clogging bacteria that leads to acne breakouts.

Spread the paste over pimples on clean, dry skin and allow it to rest for about 30 minutes, then thoroughly rinse your skin with water.
