When was Sunscreen Invented? Protecting Your Skin Through Time
Published: 15 Feb 2025
Sunscreen plays a crucial role in protecting our skin from harmful UV rays. It’s an essential part of daily skincare, helping to prevent sunburn, premature aging, and skin cancer. Over the years, sunscreen has become more advanced, offering better protection and easier application.
But have you ever wondered when was sunscreen invented? The development of sunscreen has come a long way from its humble beginnings. Let’s take a look at how this life-saving product evolved and became the must-have skincare item we use today.
When Was Sunscreen Invented?
Sunscreen was invented over time, with key developments happening in the 1930s and 1940s. These decades marked the beginning of sunscreen’s creation, as chemists worked hard to find ways to protect the skin from the harmful effects of the sun. The progress made during this period helped shape the sunscreen we use today.
Here’s a simple timeline of sunscreen’s early development:
- 1930s: Early forms of sunscreen were created, mainly as thick creams. While these didn’t offer full protection, they helped reduce sunburns.
- 1936: Eugene Schueller, founder of L’Oréal, created one of the first commercial sunscreen products, providing the public with a way to protect their skin.
- 1946: Franz Greiter introduced sunscreen with SPF (Sun Protection Factor), marking a major breakthrough in sunscreen technology.
- 1950s-1960s: Sunscreen products continued to improve, with higher SPF levels becoming available to offer better protection.
The 1930s and 1940s were crucial for sunscreen’s invention because they laid the foundation for the more advanced formulas we use today. These decades turned sunscreen from a simple idea into something that could help people protect their skin from long-term sun damage.
Who Invented Sunscreen?
Sunscreen wouldn’t be what it is today without the work of a few key scientists and chemists. These brilliant minds paved the way for sunscreen products that protect our skin from the sun’s harmful rays. Let’s take a look at the key figures behind its invention.
Here are the main inventors and their contributions:
- Eugene Schueller (1936): Schueller, the founder of L’Oréal, created one of the first commercial sunscreens. His work made sunscreen more accessible to the public and started the movement toward sun protection.
- Franz Greiter (1946): Greiter is credited with introducing the first sunscreen with SPF (Sun Protection Factor). This was a huge step in understanding how to measure sun protection and led to the development of stronger, more effective sunscreens.
- Benjamin Green (1944): A U.S. Army doctor, Green developed a sunblock formula during World War II to protect soldiers from sunburns. His work also contributed to the sunscreen we use today.
These innovators helped make sunscreen a part of our everyday lives, ensuring that we have better protection from the sun’s dangerous effects.
How Does Sunscreen Work?
Sunscreen works by blocking or absorbing harmful UV rays from the sun, which can damage your skin. The ingredients in sunscreen create a barrier that helps protect your skin from sunburn and long-term damage like premature aging and skin cancer. There are two main types of sunscreens: physical and chemical. Each works in a different way to protect your skin.
Here’s a breakdown of how both types of sunscreens work:
- Physical Sunscreens: These contain minerals like zinc oxide or titanium dioxide. They sit on top of the skin and act as a shield, reflecting UV rays away from your skin.
- Chemical Sunscreens: These contain ingredients like avobenzone or oxybenzone. They absorb UV rays into the skin and convert them into heat, preventing the rays from damaging your skin.
Both types of sunscreens help protect your skin, but they work in different ways. Choosing the right one depends on your skin type and how you prefer the sunscreen to feel.
What Does SPF Mean?
SPF stands for Sun Protection Factor, and it measures how well a sunscreen protects your skin from UV rays. The higher the SPF, the more protection it provides. SPF is a simple way to understand how long you can stay in the sun without getting burned when wearing sunscreen.
Here’s how SPF works:
- SPF Number: The number on a sunscreen bottle tells you how long you can stay in the sun before burning. For example, if you usually burn after 10 minutes of sun exposure, an SPF 30 sunscreen will protect you for about 30 times longer (around 300 minutes).
- SPF and UVB Protection: SPF mainly protects you from UVB rays, which are the main cause of sunburn. It doesn’t tell you about protection from UVA rays, which can cause long-term skin damage.
So, the SPF number is an important factor in choosing the right sunscreen for your skin. Just remember, no sunscreen can block 100% of UV rays, so it’s also important to reapply every two hours or more often if swimming or sweating.
The Evolution of Sunscreen: Pre-21st Century vs. 2017 Sunscreen
Sunscreen has come a long way since its early days. The formulas we use today are much more advanced compared to the early sunscreens of the 20th century. Let’s take a look at how sunscreen has evolved in terms of ingredients, effectiveness, and consumer awareness.
Here’s how old sunscreens compare to modern ones:
- Early Sunscreens: The first sunscreens were thick, greasy, and often difficult to apply. They mainly offered basic protection and had low SPF levels. Many early formulas didn’t protect against UVA rays, which are responsible for long-term skin damage.
- Modern Sunscreens (2017 and beyond): Today’s sunscreens are lightweight, easy to apply, and offer a broader spectrum of protection against both UVA and UVB rays. Ingredients like zinc oxide and avobenzone are commonly used for better coverage. Many sunscreens also now come in water-resistant formulas, making them more practical for outdoor activities.
- Consumer Awareness: People today are much more aware of the importance of sun protection, thanks to education and better labeling. SPF ratings are now clearer, and consumers are more conscious of choosing sunscreens that offer full-spectrum protection.
Overall, sunscreen has improved in both performance and ease of use, making it a key part of our skincare routine.
When Did the FDA Approve Sunscreen?
The FDA (Food and Drug Administration) plays a key role in making sure sunscreens are safe and effective. It took time for sunscreen to be officially regulated, but the FDA’s involvement helped ensure that the products we use today meet safety standards.
Here’s how the FDA has been involved in sunscreen regulation:
- 1970s: The FDA started reviewing sunscreens and their ingredients. However, there were no clear guidelines or standards for sunscreen products.
- 1980s: The FDA began working on developing rules for sunscreen labeling, such as how to measure SPF and what terms like “waterproof” meant. This helped improve consumer understanding.
- 2011: The FDA issued new rules requiring sunscreen labels to include both UVA and UVB protection and to limit the use of terms like “waterproof.”
The FDA’s involvement has made sunscreen products safer, more reliable, and easier to understand, so you can confidently choose the right sunscreen for your skin.
When Was SPF 50 Released?
SPF 50 is one of the highest levels of sun protection available today. Over time, sunscreen formulas have evolved to offer stronger protection, and SPF 50 was introduced as a significant milestone in the fight against skin damage from the sun.
Here’s how SPF 50 came into play:
- Early Sunscreens: In the past, sunscreens had lower SPF levels, usually ranging from 2 to 15. These were helpful but didn’t provide as much protection for longer sun exposure.
- SPF 50 Introduction: SPF 50 became widely available in the 1990s, offering stronger protection against both UVA and UVB rays. It was a game-changer for those who needed extra defense, especially for sensitive skin or longer outdoor activities.
- Significance of SPF 50: SPF 50 provides 98% protection from UVB rays, which is much higher than lower SPF levels. This helped people feel more confident in protecting their skin from sunburns and long-term damage.
SPF 50 is a great option for people who want extra protection, especially for outdoor activities or long exposure to the sun. It’s one of the strongest choices for preventing sunburn and skin damage.
Can Sunscreen Prevent Tanning?
There’s a common misconception that sunscreen stops you from tanning completely. While sunscreen is great for protecting your skin from harmful UV rays, it doesn’t completely block tanning. It helps to reduce skin damage while still allowing some tanning, depending on the SPF.
Here’s how sunscreen and tanning work together:
- SPF and Tanning: Sunscreen blocks most of the harmful UVB rays, but it doesn’t stop the skin from producing melanin, the pigment that causes tanning. With a higher SPF, you can protect your skin while still getting a tan, but it will take longer and be less intense.
- Lower SPF vs. Higher SPF: A lower SPF will allow more UV rays to reach your skin, which means you might tan faster. A higher SPF (like SPF 30 or 50) will protect you better, but it will slow down the tanning process.
- Safe Tanning: Sunscreen is important for protecting your skin from harmful effects like sunburns and long-term skin damage. It helps keep your skin safe while you enjoy a tan, but remember, tanning too much can still harm your skin.
So, while sunscreen doesn’t completely stop tanning, it makes sure that your skin is protected from sunburn and other serious damage. Always reapply for the best protection!
Modern Sunscreen Formulas: The 21st Century
Today’s sunscreens are more advanced than ever. Modern formulas offer broad-spectrum protection, which means they guard against both UVA and UVB rays. Plus, there are more options than before, including water-resistant formulas and eco-friendly choices, making it easier to protect your skin while keeping the planet in mind.
Here’s what you can find in today’s sunscreens:
- Broad-Spectrum Protection: These sunscreens protect against both UVA rays (which age the skin) and UVB rays (which cause sunburn). This helps provide full protection for your skin.
- Water-Resistant Formulas: Many sunscreens today are water-resistant, making them perfect for outdoor activities like swimming, running, or sweating.
- Eco-Friendly and Reef-Safe: Some sunscreens are now made with natural ingredients that are safe for the environment, particularly coral reefs. These sunscreens avoid chemicals like oxybenzone and octinoxate, which can harm marine life.
- Trendy Ingredients: Modern sunscreens are being made with nourishing ingredients like antioxidants, vitamins, and hydrating formulas, which help your skin stay healthy and moisturized.
With these new developments, it’s easier to find a sunscreen that fits your needs, whether you’re swimming, protecting your skin long-term, or choosing an eco-conscious product.
