A Brief History of Low-SPF Products: From Baby Oil to Modern Tanning
There was a time — not that long ago — when the ideal outcome of a beach day was the deepest, darkest tan possible. SPF didn't exist as a consumer concept. Sunburn was considered the price of admission, an unpleasant but necessary step on the way to the golden color that signaled health, leisure, and a life well-lived outdoors.
That was the landscape in which Panama Jack and a generation of beach brands were born. Their early products tell the story of American beach culture's evolving relationship with the sun — a relationship that went from unguarded worship to cautious respect over about fifty years.
The Pre-Sunscreen Era: Baby Oil and Iodine
Before commercial tanning products existed, resourceful sunbathers mixed baby oil with iodine to create a DIY tanning accelerant. The baby oil created a sun-focusing effect on the skin surface while iodine provided dark pigmentation people associated with a deep tan. This mixture provided essentially zero UV protection and accelerated both tanning and burning indiscriminately.
The First Commercial Sunscreens: 1940s–1950s
The first commercially marketed sunscreen was developed by Benjamin Green, a Miami pharmacist, in 1944. Originally created for US soldiers in the Pacific to prevent severe sunburn, Green's formula was the precursor to Coppertone, which launched its consumer version in 1953. These early products were not rated by SPF — the rating system wasn't standardized until the 1970s. They were marketed primarily on tanning benefits, not protective properties.
The SPF Rating System Arrives: 1970s
The 1970s brought standardization of the Sun Protection Factor rating system, developed by Franz Greiter and later refined by the FDA. This created the numbered system that has defined sun care ever since.
It was in this context that Panama Jack launched in 1974, with a coconut-scented tanning oil at SPF 4. At the time, SPF 4 was not considered dangerously low — it was in the middle of the commercial range. SPF 15 was considered high protection. The idea that SPF 50 would become a standard beach product would have seemed extraordinary.
Panama Jack's original heritage formula — the coconut-scented tanning oil that launched in 1974 — is still available on Amazon. The scent is the same. The summer feeling is the same.

The 1980s: Tanning Culture at Its Peak
The 1980s represented the absolute zenith of American tanning culture. Deep tans were a status symbol; low-SPF products dominated the beach market. Panama Jack, Hawaiian Tropic, and Coppertone were household names. The dermatological community was beginning to understand the link between UV exposure and skin cancer more clearly, but the message had not yet reached mainstream consumer culture.
The 1990s: The Great SPF Shift
The 1990s were the decade when sun protection science finally began changing consumer behavior at scale. The FDA's strengthened sunscreen regulations, the American Cancer Society's increasing public outreach on melanoma, and a generation of dermatologists who came of age with skin cancer prevention as a core priority all converged. SPF 30 became the consumer standard by the mid-90s.
2000s–Present: SPF Escalation and the Modern Era
The 2000s and 2010s saw SPF values escalate — SPF 50 became widely available, followed by SPF 70, 85, and eventually 100. The FDA ruled in 2012 that SPF claims above 50+ were misleading, but the cultural arms race had already normalized very high SPF numbers.
Concurrently, the low-SPF heritage category never disappeared. Panama Jack's classic tanning formulas have maintained consistent sales among consumers who understand the tradeoffs and value the specific experience these products provide.
