Scarlett Johansson has revealed she likes to clean her face with cider vinegar because it keeps her spots at bay.The 'Lost in Translation' actress admits the product can be "harsh" on skin, but she has discovered it is very effective at keeping spots at bay.She said: "I researched natural skincare and found that apple cider vinegar is really effective. Using it as a toner can be harsh, but if you have breakouts it can be really healing."The 28-year-old beauty has favourite fragrances, but doesn't stick to the same ones at all times.She said: "I love Dolce & Gabbana Desire - it's a very feminine fragrance that's best worn at night."For day, Bourbon French Parfums in Louisiana has these essential floral fragrances. I like to mix."And the 'Avengers' star also recommends using lipsticks with built-in conditioners to get her trademark stand-out red lips.She added in an interview with ELLE magazine: "Dolce & Gabbana Passion Duos have conditioner on the inside so if you like to wear red or coral lipstick, like me, you're not using a dry red, which can be chalky."
