Los Angeles: Scarlett Johansson has opened up about her skincare obsession in the February issue of Elle UK, confessing that she washes her face with apple cider vinegar.

The common household product is what she uses to keep her porcelain complexion in check and camera-ready, media reported.

"A while back, I started researching natural skincare. It's a nice way to treat your skin if you don't want to use all those harsh chemicals that a dermatologist would recommend," she told the publication.

Turns out the acidity of apple cider vinegar balances your skin's natural pH levels and restores your luminous glow much like toner.

"If your skin is problematic or you're having a lot of breakouts, it's really healing. It's a little bit stinky but if you're not sleeping over at your boyfriend's, it's really effective!" she said.

Apple cider vinegar actually has endless beauty benefits. You can use it as a DIY hair rinse to remove dirt and add shine, or use it to treat warts and nail fungus, soothe sunburns, and soften calloused skin.
