A doctor warned about using factor 50 sun cream before the hot weather. Many people think using factor 50 sun cream is enough to protect them from the sun all day.

Using factor 50 sun cream can make people feel safe, but it's not enough to stay safe in the sun. Dr. Amber Woodcock said people should do more to avoid sunburn.

Dr. Woodcock talked about a social media post where someone got burned after using factor 50 sun cream and said it was bad.

Dr. Woodcock said sunburn can be completely prevented and that it's important to avoid it because it can cause skin cancer and damage.

Dr. Woodcock said people with fair skin are not stronger than the sun, even with sun cream on.

On very hot days, factor 50 sun cream does not provide 100% protection, Dr. Woodcock said. This is an important thing to understand.

Dr. Woodcock said people often don't apply enough sun cream. Little packets and sprays are not enough because some of it gets wasted.

Dr. Woodcock said to use a lot of sun cream, like a shot glass full, and apply it all over the body. If using a spray, it should be dripping and then spread all over.

People forget to apply enough sun cream and then blame the sun cream.

Dr. Woodcock's top tip is to apply sun cream when you're not wearing clothes so you can see it on your skin.

People make a mistake by not putting on sun cream often enough, leaving their skin unprotected. Dr. Woodcock said people should reapply sun cream after some time.

Dr. Woodcock said to reapply sun cream every two hours, or every hour in tropical countries, until you can see it on your skin.

Dr. Woodcock said fair-skinned people should not stay in the sun for too long, even with sun cream, and should seek shade.

Dr. Woodcock ended by saying the sun is very dangerous and that sun cream does not cause cancer, it saves lives.

Dr. Woodcock said we are lucky to have sun cream because it saves lives.
