No, surprisingly, as the cream is quite thick.

Does it leave you shiny?
Is it sticky?

Both labelled 'Very water-resistant'

Yes. Baicalin - to protect against UV, including long UVA.

Both available from Boots.com - word of caution - Boots.com says that it contains fragrance - they're wrong. Relax. It doesn't. Someone is clearly confused by the term 'sans parfum'. ;)
