The Duchess is frequently seen wearing the pink-coloured plasters in public but with little explanation as to why
Kate Middleton ‘s fans have been left baffled after she appeared in public wearing a mystery plaster on her thumb once again.
Bemused royal watchers noticed the Duchess was wearing pink-coloured sticking plasters as she appeared at the RHS Chelsea Flower Show this week .
Sightings of of the unusual quirk have dated back years, with little explanation as to the cause .
The last time was in November when she was seen with a small circular patch on her finger.
In 2016, the Duchess wore the tape on her left thumb as she guided her then one-year-old daughter, Princess Charlotte, away from a church service in Berkshire.
Kate was then spotted with one of the items on her left hand – just a day after meeting the feline star of A Street Cat Named Bob.
Just days later, the Duchess was seen wearing a plaster on the side of her hand as she arrived at the Royal Albert Hall for the annual Royal Festival of Remembrance.
Speculation suggests that the green-fingered royal sustained minor injuries while out gardening, one of her favourite past times.
In recent days, Kate has been centre stage at the RHS Chelsea Flower Show as she presented her Back to Nature Garden which she helped design.
It’s thought that she may have picked up the minor cuts while working on the project.
When asked about the plasters previously Buckingham Palace insisted: “We have no comment on the plaster.”
While the bandages may cover up unsightly nicks and bruises, not all experts say they are entirely helpful for healing.
Dr Anton Alexandroff, a spokesman for the Consultant Dermatologist & British Skin Foundation, told the Express: “Wearing plasters isn’t that helpful because the skin doesn’t breathe as well and it takes longer to heal.
“As a mum, you are washing your hands all the time, so it is important to moisturise regularly.
“Using moisturiser is the best way to heal a scratch.”
