15+
SPF
Although you may tan very readily, you can still burn with prolonged or intense sun exposure.
When the sun is strongest (between 11am - 3pm in Northern Ireland) seek the shade and cover up with a T-shirt, hat and sunglasses.
During prolonged or intense sun exposure, wear sunscreen with SPF 15+ and 4 or 5 star rating. Apply sunscreen 30 minutes before going out in the sun and reapply every 2 hours.
