More extensive study is still needed. This is just the first step. I still would advise people to wear sunscreen. Sunscreen is better than no protection at all.So Susan, add to this all the data we have showing that sunscreen use actually prevents skin cancer IF it's broad spectrum, and I think we know what to do:
- Wear our broad spectrum zinc oxide sunscreen and know that we are taking good care of our skin.
- Cover as much skin as possible with clothing and shade our face with a broad brimmed hat when outdoors because wearing broad spectrum sunscreen does not mean it's safe to run around in the sun exposing our skin to UV rays.
- Seek out shade when possible.
- Eat lots of fresh fruits and veggies to load the skin from the inside out with free radical fighting antioxidants.
- Apply antioxidant rich skin care products to the outside of your skin. I think the best topical antioxidants for fighting skin cancer are green tea (Replenix CF or Green Tea Antioxidant Skin Therapy - Replenix Power of Three Cream being the best products for this and have the highest level of green tea antioxidants that I know of) and vitamin C if your skin can handle the acid pH. Professional Cell Repair Serum is the best of the best vitamin C products, again in my opinion.
Click here for the trustworthy zinc oxide sunscreens that I rely on for my skin cancer patients, my family and for myself. These products include some made with non-nano zinc and organic ingredients for people wanting "natural skin care" options.
Click here for the two Replenix products (that I've seen help my skin cancer patients reduce the number of skin cancers their skin develops) and Professional Cell Repair Serum, the vitamin C product that I use in my dermatology practice. I hope that helps you sort out the confusion surrounding sunscreens and your skin's health.
