As the summer season kicks in, many may find themselves increasingly exposed to the sun. Dr. Renee Beach, a dermatologist, told CTV’s Your Morning Monday that without skin protection, this exposure can cause DNA damage, which could turn into skin cancer.

According to Dr. Beach, although many people only wear sunscreen in the summer, skin protection should be done throughout the year.
“Even when we can’t see the sun…we still have UVA (Ultraviolet A) rays,” she explained. “These are the rays that pass through windows and windshields, these are the ones that we sometimes see in the reflections of the snow, for example. »
When there is direct exposure to the sun, Dr. Beach explains, people come into contact with UVA rays and ultraviolet B (UVB) rays. To protect the skin, it is necessary to apply sunscreen.
“SPF stands for sun protection factor, and we often hear that an SPF 30 is the right thing to put on the skin,” she said. “The reason for this is that it equates to about 97% protection against ultraviolet or UV radiation from sunlight during the day.”
Applying the right sunscreen and the right amount are other important factors in skin protection.
Dr. Beach recommends using about a quarter teaspoon of sunscreen on the face. If sunscreen is applied to both face and neck, about half a teaspoon should be used
“When we look at the whole body, it’s more like a shot glass or 30 milliliters,” she clarified.
This amount should be reapplied often depending on the activity, Dr. Beach said. If an adult is outdoors doing activities like running, biking, or swimming, she recommends reapplying sunscreen every two hours.
But for children, the reapplication and amount of sunscreen should be different, Dr. Beach added.
To make sure kids aren’t exposed to high levels of UV rays, the best thing to do is cover them up, she said.
“They should wear a blunt hat, as well as splash-proof clothing, i.e. long-sleeved clothing,” she mentioned. “Then it’s just about keeping them out [du soleil] during peak hours, which are usually between 11 a.m. and 3 p.m.
