Reddit mentions of Heliocare Skin Care Dietary Supplement: 240mg Polypodium Leucotomos Extract Pills - Antioxidant Rich Formula with Fernblock and PLE Technology - 60 Veggie Capsules

1. Vitamin C serum.
   
   The classic one is Skinceuticals CE Ferulic but there are cheaper versions around that give you nearly all the benefits that Skinceuticals has (Timeless Skin Care 20% Vitamin C Plus E Ferulic Acid Serum or Cosmetics Solutions CE Ferulic Combination Treatment are more affordable options). Other ingredients to look for is niacinamide, green tea, resveratrol, hyaluronic acid -- you need to make sure your skin is well hydrated and has ingredients that fight off free radical damage.

2. Heliocare.
   
   There is also a supplement called Heliocare that has Polypodium leucotomos fern in it that has been shown to protect your skin from the free radical damage that you get from sun exposure (you still need to wear sunscreen though).

3. UV film on your car.
   
   It sounds like you spend a lot of time outdoors and I'm not sure how much of that is spent driving but just in case you do drive quite a bit, it might be worth getting UV film on the drivers side window and on the windshield. I got mine done at a local shop that does tinting for cars.

I would recommend a pill called Heliocare in conjunction with sunscreen. If you can afford it, it's an oral, herbal supplement you take two of a few hours before going out in the sun. I was really skeptical at first, but eventually I started using just it, no sunscreen, and it kept me from even tanning. If you use both in conjunction(I recommend zinc sunscreen btw, the woolies brand is good if you're in Australia) you should be pretty darn well protected. Of course, a swim shirt is always an option if your ok not going shirtless.
