The SPF number tells you how much longer you can stay outside without burning while wearing the sunscreen product as opposed to not wearing any sun protection product, example: An SPF 15 means that this will take your lips 15 times than they would without the sunscreen
Wear lip balm with a minimum SPF 30 for you (higher is better), and SPF 15 for your baby. But most famous lip balm usually only have an SPF with 15-20, it is still not protect your lips from.
- Apply sunscreen 30 minutes before going in the sun and re-apply every 2 -3 hours when swimming or sweating ( Water proof or Sweat proof).
- No sunscreen can protect your skin from all of the UV rays, but a higher SPF number indicates protection from more rays.
- Do not go in direct sun light without any sun protection factors. Apply lip moisturizer's which contain sun protecting factor in them.
- "It's winter! I don't need to protect my lips from the sun!" Snow can reflect about 80 % of sun rays and can result in skin damage and UVA rays are at constant levels all year
Thats it
