To accomplish that; the Princess used to exercise every morning after she wake up at 7:00 am. After having her healthy breakfast; she would start running around Kensington Gardens for an hour, and at 8:00 am, she headed to the gym for another hour of hard workout.

Since that Diana was addicted to exercise, she would often do some extra moves at night. At the floor of her living room, she would do some upward crunches and side-to-side crunches to get a stronger stomach and a proper waistline.

Although Diana knew that starting the day with a cup of coffee is unhealthy, she thought that it would give her the kick-start to the day. So, every morning, she has a regular cup of coffee that was freshly made from ground beans. 

However, when she first woke up, Diana prefers to have a hot cup of water and lemon. Her favorite juices were a mixture of organic cucumber, beetroot, celery, or carrot and apple. Diana believed that this fresh mixture of fruits are very healthy and good for detoxing and that it will help keep the liver function properly.

For food, she usually have muesli, a slice of organic toast or her favorite; croissant! The Princess made sure that her fruits and vegetables were organic. They were bought from Planet Organic Market in Notting Hill.

• Skin Care

Diana always scrub her face well after washing it with a plain glycerine soap, because she had a sensitive skin, and then apply a toning lotion made of rosewater and glycerine and a pre-moisturising mix of one drop of rose oil to two of geranium oil she made herself.

Diana loved to use Guerlain moisturizer. She also preferred to use body lotions from Johnson & Johnson as well as Vaseline. The Princess also loved to tan her skin at least three times a week by an electric sun-bed she used at home.

She was also keen in creating natural and healthy facial masks inside her laboratory; her kitchen. For a softer skin and cleaner face after wearing make up all day, Diana would made a mixture of avocado, a white of an egg, lemon juice and honey. 

To refresh her tired skin, she mashes avocado in the blender and put it on her face, or whip a white of an egg, brush it on her face and add two slices of cucumber cut at an angle and place it over her eyes and lie down for 40 minutes. 

If a spot was notices in her face, she would dab it with witch hazel, or lightly steam her face with water that had just boiled and had two spoons of sea salt in it. After applying these natural masks on her face, Diana would wash it with warm then cold water for good results.

• Make Up & Perfumes

Diana loved Kenzo perfume and was fond of Penhaligon. She used their Gardenia scent in the shower and Bluebell when having a long soak in the bathtub.

Moreover, Diana's favorite make up style was wearing simple colours. Her first choice of make up collection were from Guerlain. For cheeks, Diana used a light pink blusher. For lips, she opted for a pinkie brown lipstick worn under a natural gloss. For eyelashes, she would never curled them. Instead, Diana used a hyper allergenic mascara. Inside her eyes, Diana used to highlight them with a very fine blue or black pencil.

For her hair, Princess Diana regularly visits her favorite Hair Dressers, Sam McKnight and Daniel Galvin, to cut her hair or do blonde highlight. For waxing and facial; Diana visits an Iranian woman’s salon at Kensington High Street.
