A study published by the Smell and Taste Treatment and Research Foundation discovered that beauty and the perception of being younger may not be in the eyes of the beholder but in the nose of the beholder.
The researchers found that women wearing a grapefruity fragrance were perceived by as being an average of 6 years younger!
Two fragrances that have this grapefruity scent are Eau de Parfum Light Citrus Floral by Aubrey Organics or Trillium fragrances.
Or you can just go out and buy a grapefruit (probably pink), cut and squeeze!
