FYI My Dermatologist suggested Neutrogena Sun block with Helioplex SPF 45 or 70. I tried the SPF 70 on our cruise and liked that it doesn't have the greasy feeling. I tan easily but I like to protect my skin nonetheless. The sun is strong and HOT in the Caribbean and it reflects it's rays off the waters underneath your umbrella! It kept my entire family from sun burn....except on the spots that got missed.
But here's something interesting. I had funny tan lines, white feet from playing tennis, shorts marks and a perfect sports bra tan on my back from road cycling. Doc had also suggested using a spray on tanning product (Magic Tan, etc) if one didn't want to look too white or burn on the first day(s) out. Well, I used it to even out the shorts tan, on my feet, and back. I looked nearly even in my low back evening gown and slip on shoes. But what surprised me that after it wore off (in about a week) I had no tan underneath! So I STILL have white feet, shorts marks and a bra tan on my back! But the rest of me looks tan!
) If you want to look tan and get sun protection you can use a tanning spray with sun protection factors.....I used Banana Boat Spray On Tan.
In case you are like me and didn't understand fully how sunscreen works, it protects you from getting the most damaging rays of the sun too deep into the layers of your skin but you will still tan. A tanning booth will tan you but the rays go too deep. Doc says suit iw worse to use a tanning booth be in the sun without sunscreen!
