The research, carried out by the British Association of Dermatologists, also revealed that a "shocking" 72% of people admitted having been sunburned in the previous year.
With sunny days already making an appearance in parts of the UK, it is likely that this figure will remain high this year.
"This is a reflection of poor sun protection habits - people underestimate the damage that sunburn can do to their skin, and many think that skin reddening is just a harmless part of the tanning process, rather than a sure sign that you have damaged your skin irreparably..
The research, carried out last summer, surveyed 1,018 people and found 84% were worried about skin cancer in the UK climate.
People who have been sunburned before are doubly at risk of developing melanoma, the deadliest form of skin cancer, than those who have not been, the Association said.
Today marks the beginning of Sun Awareness Week, which aims to inform people of the dangers of the sun and how to protect themselves.
