Detailed Answer:
Hello again.

Take these precautions.

Try to avoid sunscreen if there is injured or raw skin.
Dry the face to a fan (at mild speed) before going outside.
Don't go out with a wet sunscreen applied freshly on the face.
Another option would be to change the sunscreen.
The sunscreen can be combined with glutathione and vitamin c and then applied. It will also help in reducing the burning sensations.

Wishing you best of health

Thanks
