What ever SPF you choose, look for sunscreens that protect you against both UVA and UVB radiation, and have antioxidants to provide you with a secondary line of defence against damage by free radicals.
In addition, where your face skin is super sensitive to sun and prone to spots or blistering, like the nose and area around the cheekbones, generously apply some Chapstick SPF35 or Blistex30. Both are invisible and they will save your skin. Remember, damage to the face from sun is cumulative.
