What is it? While grapefruit is typically associated with one's diet, it can also do amazing things for the skin. First documented in 1750 by Reverend Griffith Hughes in a theological discussion on Biblical fruit, grapefruit is considered one of the "Seven Wonders of Barbados" because of its health and skin benefits. Today, skincare companies are taking full advantage of this natural ingredient by including grapefruit in a variety of products.

You'll find it in: Not only does grapefruit contain natural exfoliators, but the smell is also uplifting, making it an excellent addition to scrubs, lotions and bubble baths. Many high-quality anti-aging serums, oils and creams also contain grapefruit to promote smoother, younger looking skin.

Our product picks: Infused with grapefruit, hazelnut oil and sandalwood, Pevonia Face Oil - Combination provides a healthier, hydrated complexion. Also, try Murad Essential-C Daily Renewal Complex, whose blend of grapefruit, mandarin oranges and basil boosts collagen production, calms the skin and increases elasticity, giving you powerful protection against free radical damage.

What to expect: Rich in citric acid (an alpha hydroxy acid), grapefruit extract is a powerful exfoliator and will loosen dead skin cells and exfoliate dry skin. Additionally, the smell of grapefruit has some unique anti-aging benefits: According to the Smell & Taste Treatment and Research Foundation in Chicago, research has shown that men believed women wearing grapefruit were, on average, six years younger.

Who should avoid it: As an alpha hydroxy acid, grapefruit can be potentially drying or irritating, so it might not be ideal for those with sensitive skin. If you're interested in trying a grapefruit product, first do a patch test. Most people, however, can safely use products containing grapefruit.
