How do you apply sunscreen correctly?
Qmusic
On Qmusic, Dr Griet Voet answered questions about sunscreen: how often to apply it, spray or cream, sun behind glass and in winter.

In a live interview on Qmusic, Dr Griet Voet answered listeners' questions about sun protection. She explained that both burning and tanning are signs of skin damage, and that this damage increases the risk of skin cancer over the years.
Topics included how often to apply sunscreen, whether a spray protects as well as a cream, whether you can burn behind glass and whether sunscreen is also needed in winter. She also talked about choosing a sunscreen according to skin type, sun protection for children, recognising a conspicuous mole and the trend of salmon sperm in skincare.
Key advice
Reapply SPF 50 every two hours when you are really out in the sun.
A spray often gives too thin a layer; a cream protects better.
Apply sunscreen behind glass and in winter too, as UVA radiation keeps ageing the skin.
Have a mole that looks different from the rest checked by a dermatologist.
