Hi Jeanne. You will be just fine for you reunion; and you'll be so pleased w/the results of your treatment once the healing is well under way. I ordered the Sunblocks via the internet from Drugstore.com and also from the product label...here is the info? Ti-silc is available at Drugstore.com..when I ordered it several weeks ago, it was on sale $16.00 for 4 oz. The BEST is Fallene Total Block SPF 60. it covers beautifully and evenly even when your skin is "eroding." The web address is www.totalblock.com, phone # 800.332.5536. This will lead you to Total Block, and COTZ, SPf 58 which is great, too. They're a little pricy but well worth it. Yes, my sun bathing regimen was not mentally well; I'd be late for dates and events just to make sure I got my hours in between noon and 2 pm..the WORSE time to be in the sun. And, I started in March, ended in Nov. every year for way too long. I would compete w/everyone and anyone for the darkest tan...I HAD to have it. Consequently, I'm also having problems on my arms. I can't even imagine doing that now and I always wear a hat, sunglasses and sun block on my face and any other exposed areas. Well, good luck to you. And stay healthy. Kathy
