1. It’s just a tan

3. One person dies of melanoma every hour (every 57 minutes) Melanoma is the most common form of cancer for young adults 25-29 years old and the second most common form of cancer for young people 15-29 years old. 17 On average, a person’s risk for melanoma doubles if he or she has had more than five sunburns. 19 Sustaining 5 or more sunburns in youth increases lifetime melanoma risk by 80 percent

4. One indoor UV tanning session increases users’ risk of developing squamous cell carcinoma by 67 percent and basal cell carcinoma by 29 percent. People who first use a tanning bed before age 35 increase their risk for melanoma by 75 percent More people develop skin cancer because of tanning than develop lung cancer because of smoking

5. What does Tanning do? Wrinkles Increases the enzymes that break down collagen (structure of skin cells) Sagging skin Breaks down elastin (allows skin to bounce back) Age spots Cells that contain melanin enlarge and cluster together

6. Rough/Dry skin UVA/UVB damages collagen and elastin  water escapes easier, light absorbed so duller Spider veins UV dilates them and brings to surface Eye probs Early cataracts Skin Cancer

7. So what actually happens When you burn?
