What are the active ingredients in sunscreen?
There are two main ways that UVA and UVB are blocked – by chemicals that absorb the rays or mineral sunscreens, which are physical barriers.
Chemical sunscreens are adequate for two weeks in Florida but are not advisable for daily use all year round especially if you have sensitive skin or allergies.
Mineral sunscreens; namely zinc oxide and titanium dioxide are gentler on the skin. These used to be chalky, thick and sticky but they are now more user friendly with new formulations including some that are tinted.
In conclusion, a suntan is tempting but to prevent sun-damaged skin and reduce your skin cancer risk, a year-round SPF is advisable.
A high factor goes some way to counteracting the effects of not applying enough product and mineral ingredients are preferable to harsh chemicals being applied daily to the skin.
