The SPF 70 Sunburn That Cost Me $482

Seven blisters, in a row across both shoulders. Cancun, 8:15 at night on a Saturday in June, hotel bathroom, me standing in a strapless cover-up while my husband counted them out loud behind me like he was reading a grocery list. The skin under each one had gone from pink to the exact color of the terracotta tiles on the walk between the pool and our building. The good arm, which we had started calling the left one, had only four.

The calendar made it worse than a vacation story. My sister's wedding in Austin was 19 days out, the maid of honor dress cost $340 and had an open back, and I would be standing at the front of a sanctuary in front of 140 people with those shoulders in frame. The photographer had been paid $2,800. None of that could be rescheduled.

The stupidest part was sitting in the bathroom trash can the whole time. The bottle was a $21.99 reef-safe spray I had ordered off Amazon on May 30, and it claimed SPF 70 in letters tall enough to read from a pool lounger. What it never volunteered, at least not anywhere I had looked, was printed on the back panel under the word directions, and I read that panel for the first time on the flight home.

the $21.99 bottle from Amazon

I bought it cuz of the reef ban. Mexico restricts certain chemical filters, the listing said reef-safe twice in the title, and the review count sat at 1,847 with a 4.4 average, which felt like a crowd walking in front of me. I sprayed it once that mornin', 9 a.m. sharp, in the room, arms and shoulders and the back of my neck, and then I walked to the marina and got on a catamaran with eleven other people. The can went into the beach bag and stayed there. Five hours of snorkeling followed, 10 to 3, most of it face-down and shoulder-up in water that reflects like a lens.

day two, the blister row

By Monday mornin' the pink had become ridges. I wore a tank top to breakfast and a woman at the next table asked, kindly, whether I had fallen asleep in the sun, and the honest answer was that I had done everything except the one thing that mattered. That afternoon we walked into a clinic off the hotel zone, and a doctor named Guillermo Reyes looked at both shoulders for maybe three minutes and said the word second-degree in accented but altogether clear English. Silver sulfadiazine cream, prescribed on the spot, $42 at the pharmacy next door. The visit itself was $85 cash, no paperwork, and honestly the most efficient medical transaction of my life.

Here is what the back panel said, once I finally turned the can around somewhere over the Gulf. Apply 15 minutes before sun exposure. Reapply after 80 minutes of swimming or sweating. I had applied once, at 9, and swum from 10 to 3. Four missed reapplications. Each one was a door I did not open, and my dermatologist would later compress the whole failure into four words: reapplication is the product. The 70 on the front was real. The zero on the back was the product I actually used.

the Austin fitting, strapless

The dress fitting on June 12 lasted eleven minutes and ended early. Marge, the seamstress, took one look at the shoulders and pulled a sheer bolero from the rack in a shade the shop called champagne, $45, and the three of us, her pins, and my scabs held a silent conference in the mirror. The blisters were still crusting. The bolero covered the worst row and photographed like a style choice. I bought it on the spot and hated how relieved I was.

what the dermatologist charged for eleven minutes

Dr. Ferrell at Westgate Dermatology saw me on June 17, ten days before the wedding, and my copay tier billed $150. Eleven minutes in the room. She checked the healing, called the scarring risk low on the right shoulder and real on the left, where the deepest blister had sat, and sold me a scar gel off the office retail shelf, $95 for one ounce, twice a day through the wedding and well past it. With an $18 sunscreen stick she approved for reapplication over healing skin, that visit came to $263.

the deposit I ate

One more number, easy to forget because it bought nothing. The cenote tour on the afternoon of day two, the one with the underwater camera guide, was a $47 deposit, forfeited when I could not lift my arms high enough to pull a wetsuit on. My husband went alone and came back with photos I am in none of. Add it up with me: $85 clinic, $42 cream, $45 bolero, $263 at the dermatologist, $47 deposit. The burn cost $482. The snorkeling was free.

the left shoulder now

A month after the burn there is a spot on the left shoulder, about the size of a thumbnail, slightly lighter than the skin around it. The gel goes on twice a day, mornings before work and nights before bed, from a bottle that is a third gone. The wedding came off without a visible wound. The bolero stayed on through the ceremony, came off for the last dance, and the photographer's shots of the back row are the only evidence anything happened. I keep one on my phone. The shoulders in it are covered, which was the whole plan.

the carry-on, restocked

The can that began this went into a hotel trash chute on day three, empty, cuz I had finally read the entire panel. What lives in my carry-on now is the $18 stick from Dr. Ferrell's shelf and a phone timer that goes off every 80 minutes in salt water, a rule with no exceptions, including the one about looking ridiculous reapplying over a rash guard at a marina. My husband still counts things out loud behind me sometimes, the way he counted blisters that first night. Lately the count is reapplications. Nine on the last trip. Zero blisters.
