I use Neutrogena Ultra Soft Hydrating Sunblock in SPF 45 for my body. It goes on like a body lotion. This is important to me because I've found that some sunblocks can leave my skin feeling coated and sticky. For my face I use Ultra Soft Dry Touch Sunblock in SPF 45. Again because it absorbs well and doesn't leave me feeling coated. According to my dermatologist friend anything above an SPF 45 is more or less a waste of effort. Just some extras about sunblock
- reapply after swimming or sweating heavily
- apply atleast 15 mins before you go out in the sun
- Look for one that blocks BOTH UVB and UVA
- When applying sunblock dont forget your neck, back of your neck and shoulders and cleavage.
When Im' not going to be in the sun excessively I use a facial moisturizer with an SPF in. I use Oil of Olay Complete for Normal Skin in SPF 15, for daily sun exposure. I work nights so this may be excessive, but I'm establishing a routine so that should I ever have to start working in the day again I won't have to change much. When you are vegas another suggestion would be to avoid being outdoors during the hours of 11-2. I know I know its a huge chunk of time but that when the sun is at its most intense. I'm sure you can busy yourself in the Forum Shops at this time. MAC Pro maybe?
If you have to be outside during this time make sure you wear a wide brimmed hat.
Enjoy your trip and have fun.
