Laura Harker, Chief Screening Nurse at The Mole Clinic, said: This is because their skin is much more sensitive than adult skin, and the damage caused by repeated exposure to sunlight can lead to skin cancer in later years. “

She said, “Depending on the age and strength of the sun, parents recommend that their children use at least SPF30. Ideally, during the summer, children should be properly dressed and shaded. You have to spend time in, especially from 11:00 am to 3:00 pm when the sun is strongest. “

3. Why do sunscreens sometimes give you spots?

“This can often be due to the formula,” says Cleeve. “Physical formulations can adhere to the surface of the skin and cause irritation, and the presence of scents and emulsifiers can cause sensitive skin to react.”

“Waterproof sunscreens don’t really exist. Water resistant sunscreens do,” says Edmonds. That is, it has been tested to ensure up to 40 minutes of underwater resistance.

7. Are expensive sunscreens really good, or are you just paying for the brand name?

When choosing a sunscreen, regardless of brand or price, you need to consider the SPF number (UVB), percentage UVA filter, and formula, says Cleeve. “Choose an SPF of 30 or higher and a UVA percentage filter of over 90%. Ultrasun makes it easy to give percentages to your product.”

Harker recommends choosing products with a 4-star or 5-star UVA rating instead of ” [based on] High prices do not necessarily mean high protection. “

Beyond these important ratings, Edmonds states that the price difference between sunblocks results in “technology and texture.” Like many things in life, you get what you pay for. Better quality sunscreens generally provide better ingredients, joy, and better protection for your skin, but you can get enough protection from affordable products. “
