Grapefruit, Citrus grandis or Citrus paradisi, is a citrus fruit indigenous to the West Indies and is now cultivated in warm subtropical climates throughout the world. Grapefruit contains Vitamin C & B5, potassium, iron, calcium and folate. Pink and red grapefruit also contains lycopene, a phytonutrient that can help fight oxygen free radicals. For this reason, this powerful antioxidant is commonly found in anti-ageing and anti-wrinkle products. Due to the antioxidant and detoxifying nature of phytonutrients found in grapefruit, it is used as a beneficial natural ingredient in skin and hair care.
