Shopping for sunscreen can be confusing with all the terms and claims on product labels. You may have heard of therapeutic or cosmetic sunscreens and wondered about the difference—or why some sun protection products are labeled with terms like "sun balms," "sun sticks," or "sun drops." In this guide, we’ll explain what therapeutic and cosmetic sunscreens are, how they’re regulated around the world, and how to choose the best option for your skin and lifestyle.
What Is Therapeutic Sunscreen?
Therapeutic sunscreens are specifically designed to meet stringent safety and efficacy standards. These products are regulated as over-the-counter (OTC) drugs in many countries and are tested to ensure they provide effective protection against harmful UV radiation.
Key Characteristics
- Regulated for Efficacy: Therapeutic sunscreens undergo extensive testing to ensure they protect against both UVA and UVB rays, reducing the risk of sunburn, premature aging, and skin cancer.
- Broad-Spectrum Protection: To qualify as therapeutic, sunscreens must provide comprehensive coverage against both UVA and UVB rays.
- Globally Regulated: Therapeutic sunscreens are regulated by government agencies like the Therapeutic Goods Administration (TGA) in Australia and the Food and Drug Administration (FDA) in the U.S.
How to Identify Therapeutic Sunscreens
- In Australia: Look for the letters "AUST L" or "AUST R" on the packaging, which indicates the product is listed in the Australian Register of Therapeutic Goods (ARTG). You can also search for the product in the ARTG online database.
- In the U.S.: Check for the Drug Facts label, which confirms the product meets FDA standards for broad-spectrum protection and SPF efficacy.
What Is Cosmetic Sunscreen?
Cosmetic sunscreens are designed with an emphasis on aesthetic appeal and skincare benefits, offering features like lightweight textures, added moisturizers, or a seamless finish. While they do provide UV protection, they are typically subjected to less rigorous testing compared to therapeutic sunscreens. These products are often marketed under names like “sun balms,” “sun sticks,” or “sun drops,” blending sun protection with skincare and cosmetic appeal.
Key Characteristics
- Minimal Regulatory Oversight: Cosmetic sunscreens may not meet the same testing standards as therapeutic sunscreens. Their focus is typically on improving the feel or appearance of the product rather than maximizing UV protection.
- Not Always Broad-Spectrum: Cosmetic sunscreens may not offer broad spectrum protection and only protect against UVB rays, leaving your skin vulnerable to UVA damage.
- Popular for Everyday Wear: These products are often marketed for daily use, especially under makeup, due to their lightweight and non-greasy formulas.
Therapeutic vs. Cosmetic Sunscreens: The Key Differences
Understanding the key differences between therapeutic and cosmetic sunscreens can help you choose the best product for your needs. Here's a quick comparison:
| Aspect | Therapeutic Sunscreen | Cosmetic Sunscreen |
|---|---|---|
| Purpose | Provides robust protection against UV rays | Focuses on aesthetics and skincare benefits |
| Regulation | Heavily regulated (e.g., by TGA, FDA) | Minimal regulatory oversight |
| Broad-Spectrum Protection | Required to protect against both UVA and UVB rays | Not always broad-spectrum |
| Testing Requirements | Must pass extensive safety and efficacy tests | Limited testing requirements |
| Usage | Ideal for long outdoor exposure | Great for lightweight, everyday protection |
How Are Therapeutic Sunscreens Regulated Globally?
Different countries regulate therapeutic sunscreens in unique ways, reflecting their respective safety and efficacy standards.
- Australia: The TGA oversees therapeutic sunscreens, which must undergo pre-market approval to ensure they meet rigorous standards. Look for "AUST L" or "AUST R" labeling.
- United States: The FDA regulates sunscreens as OTC drugs. Therapeutic sunscreens must have a Drug Facts label and provide broad-spectrum protection with SPF labeling.
- European Union: Sunscreens are classified as cosmetics but must meet high standards for UVA and UVB protection. The EU allows advanced UV filters like Tinosorb S and Mexoryl SX, which are unavailable in the U.S.
- Asia: In countries like Japan, China, and South Korea, sunscreens often combine therapeutic protection with skincare benefits. These products are tested for only UVA protection under the PA system.
- Canada: Sunscreens are regulated by Health Canada as either natural health products or non-prescription drugs, depending on their active ingredients.
The Pros and Cons of Testing and Regulation
The strict testing and regulation of therapeutic sunscreens ensure that consumers receive effective and safe sun protection. By meeting rigorous standards, these products can provide confidence and peace of mind for those looking to shield their skin from harmful UV rays. However, these regulations can also present certain challenges, particularly when it comes to innovation and accessibility.
Benefits of Testing and Regulation
- Reliability: Regulatory oversight guarantees that sunscreens deliver on their promises, such as accurate SPF ratings and broad-spectrum protection.
- Safety: Thorough testing ensures that the active ingredients in therapeutic sunscreens are safe for human use, minimizing risks of irritation or adverse reactions.
- Global Standards: Countries with strict regulations, like Australia and the U.S., set benchmarks that help protect consumers from subpar products.
Drawbacks of Regulation
- Limited Filter Options: Some regulatory bodies, like the U.S. Food and Drug Administration (FDA), have not updated their approved lists of UV filters in decades. This restricts the availability of newer, more advanced sunscreen ingredients.
- Innovation Barriers: Lengthy approval processes for new filters can stifle innovation and delay the introduction of cutting-edge products.
- Access and Usage Restrictions: Because sunscreens are considered over-the-counter (OTC) drugs in the U.S., their use is banned in many schools unless provided with a doctor’s note. This poses a significant issue given that sun protection during childhood is vital for reducing the risk of skin cancer later in life.
- Travel and Access: Travelers often purchase sunscreens in places like the EU, Japan, or South Korea, where more advanced filters (such as Tinosorb S, Mexoryl XL, and Uvinul A Plus) are widely available. These filters offer superior UVA and UVB protection, lightweight textures, and enhanced stability, making them highly desirable.
For instance, the EU and Asian markets prioritize both efficacy and cosmetic elegance, allowing consumers to access sunscreens that combine advanced filters with a lightweight, non-greasy feel. In comparison, some countries' slower regulatory processes mean consumers might not have access to these innovations at home.
Key Takeaway
While strict regulations ensure that therapeutic sunscreens are safe and effective, they can sometimes limit the range of products available to consumers. Exploring sunscreens abroad, especially in regions with advanced offerings, can provide new options for those seeking enhanced protection and skin-friendly formulations. Additionally, advocacy for changes in local policies, like allowing sunscreen use in schools, is critical for improving sun protection practices for future generations.
How to Choose the Right Sunscreen
Whether you prefer therapeutic or cosmetic sunscreen, protecting your skin from UV rays should always be the priority. Here are some tips to help you make an informed choice:
- Look for Broad-Spectrum Protection: Ensure your sunscreen protects against both UVA and UVB rays.
- Check for Regulatory Approval: In Australia, look for "AUST L" or "AUST R." In the U.S., check for a Drug Facts label.
- Choose SPF 30 or Higher: Dermatologists recommend SPF 30 for daily use and SPF 50+ for prolonged outdoor activities.
-
Consider Your Skin Type:
- Sensitive Skin: Opt for mineral sunscreens with zinc oxide.
- Oily Skin: Choose lightweight, non-comedogenic formulas.
- Supplement with UPF Clothing: Pair sunscreen with UPF-rated clothing, wide-brimmed hats, and sunglasses for comprehensive sun protection.
The Bottom Line
Understanding the differences between therapeutic and cosmetic sunscreens can empower you to make the best choices for your skin’s health. Therapeutic sunscreens provide reliable, broad-spectrum protection and meet rigorous regulatory standards, making them an excellent option for extended sun exposure. Cosmetic sunscreens, while less regulated, offer lightweight and skincare-focused options for everyday use.
Whether you prefer therapeutic or cosmetic sunscreen, the best choice is one you’ll use consistently. Choose a sunscreen that meets your standards and fits seamlessly into your routine to ensure effective, everyday sun protection.
