For many, sunscreen is considered an everyday essential for beaches, sporting events, vacations, and outdoor work. It has become a major part of global skincare markets and is available in countless forms including lotion, spray, stick, gel, powder, moisturizers with SPF and cosmetic products with sun protection.

But what did people do to protect their skin from the sun prior to modern sunscreen? Long before modern SPF ratings and spray-on lotions existed, civilizations around the world were experimenting with ways to shield themselves from intense sunlight and heat.

This In The Mix blog reviews the history of sunscreen, exploring its scientific, cultural, and medical roots, as well as changing consumer trends, leading to today’s global industry producing millions of gallons annually.

Ancient Civilizations and Early Sun Protection

Thousands of years ago, people already understood that excessive sun exposure could damage the skin.

Ancient cultures used natural materials to help protect themselves from the sun, including:

  • Rice bran extracts in Asia
  • Jasmine and plant oils in India
  • Zinc oxide-like pastes in ancient Greece
  • Clay, mud, and mineral-based coverings in Egypt
  • Olive oil mixtures used around the Mediterranean

In ancient Egypt, lighter skin was often associated with status and beauty, leading many people to avoid direct sun exposure whenever possible. Protective clothing, shaded structures, and natural skin coverings were commonly used.

Although these early methods were primitive compared to modern sunscreen, they represented some of the first attempts at UV protection.

The Rise of Recreational Sun Exposure

For centuries, many cultures associated tanned skin with outdoor labor. In Europe and North America during the 1800s, pale skin was generally considered fashionable.

That perception began changing in the early 20th century.

As travel, tourism, and beach vacations became more popular, sun tanning increasingly became associated with leisure, health, and wealth. Outdoor recreation expanded rapidly, and spending time in the sun became a lifestyle trend.

This cultural shift created growing demand for products that could help people stay in the sun longer while reducing painful sunburns.

The Birth of Modern Sunscreen

Modern sunscreen development accelerated during the 1930s and 1940s. Several major innovations by ell-known chemists and the U.S. military helped shape the industry.

In the 1930s, chemists began developing products specifically designed to absorb or block ultraviolet radiation. One of the earliest commercial sunscreen products was introduced by French chemist Eugène Schueller, the founder of L’Oréal.

Around the same time, Austrian chemist Franz Greiter began researching sunburn prevention after experiencing severe sunburn while mountain climbing.

Sunscreen development advanced significantly during World War II. Military personnel stationed in tropical regions needed protection from intense sunlight during long deployments. The U.S. military experimented with various protective compounds to help reduce sunburn among soldiers.

One early solution was a thick red petroleum-based substance nicknamed “red veterinary petrolatum.” While not especially comfortable or cosmetically appealing, it helped inspire future sunscreen formulations.

The war accelerated interest in practical sun-protection products that could be mass-produced reliably.

The Introduction of SPF

One of the biggest milestones in sunscreen history came in the 1960s when Franz Greiter introduced the concept of SPF — Sun Protection Factor.

SPF provided consumers with a measurable way to understand how effectively a sunscreen product could protect against UVB radiation associated with sunburn.

SPF \approx \frac{\text{Time to Sunburn with Sunscreen}}{\text{Time to Sunburn without Sunscreen}}

This system helped standardize sunscreen labeling and became the foundation for modern sunscreen marketing and product development worldwide.

Advances in Modern Sunscreen Technology

Over the following decades, sunscreen formulations became far more sophisticated.

Manufacturers developed products with:

  • Broad-spectrum UVA and UVB protection
  • Water resistance
  • Improved cosmetic feel
  • Spray and gel formulations
  • Non-greasy textures
  • Mineral and chemical UV filters
  • Moisturizing ingredients
  • Sensitive-skin formulations

Today’s sunscreen products often combine skincare, cosmetics, and sun protection into a single formulation.

Mineral vs. Chemical Sunscreens

Modern sunscreens generally fall into two broad categories: mineral and chemical.

Mineral sunscreens typically use ingredients such as zinc oxide and titanium dioxide. These ingredients help reflect or scatter UV radiation away from the skin.

Chemical sunscreens use active compounds that absorb UV radiation before it can damage the skin. Common active ingredients may include:

  • Avobenzone
  • Octocrylene
  • Octisalate
  • Homosalate

Both approaches require highly controlled manufacturing processes to maintain product consistency and stability.

The Manufacturing Side of Sunscreen

As sunscreen formulations have become more advanced and sophisticated, the manufacturing processes used to produce them have also become increasingly precise and highly engineered. Modern sunscreen formulations often contain:

  • Oils
  • Water phases
  • Emulsifiers
  • Stabilizers
  • UV-blocking compounds
  • Fragrances
  • Preservatives
  • Skin-conditioning ingredients

These materials must be carefully blended to maintain:

  • Stable emulsions
  • Uniform SPF distribution
  • Smooth texture
  • Consistent viscosity
  • Reliable shelf life

Industrial mixing systems play an important role in helping manufacturers produce large volumes of sunscreen products while maintaining quality and consistency.

Final Thoughts

The history of sunscreen reflects changing ideas about health, beauty, science, and outdoor lifestyles. What began as simple natural sun barriers thousands of years ago has evolved into a sophisticated global industry supported by advanced chemistry and manufacturing technology.

Today’s sunscreen products help millions of people enjoy time outdoors more safely — and behind many of those products are carefully engineered industrial mixing processes that help ensure quality, stability, and performance.
