Can Oral Sunshield Really Prevent Sunburn? What Experts Say

In recent years, the beauty and skincare industry has witnessed a surge in innovative products, and one of the most talked-about trends is the concept of oral sunshield. Also known as drinkable sunscreen or oral sun protect, these products claim to offer internal UV protection, reducing the risk of sunburn and long-term sun damage. But do they really work? In this blog, we’ll explore the science behind oral sunshields, the types of oral sunshields available, and what experts have to say about their effectiveness. We’ll also discuss how internal UV protection differs from traditional external sunscreen and highlight some of the best oral sunscreen in India.

What Is An Oral Sunshield?

An oral sunshield is a dietary supplement designed to provide protection against the harmful effects of ultraviolet (UV) radiation from the sun. Unlike traditional sunscreens that are applied topically, these products are ingested, claiming to work from within the body to neutralize free radicals, reduce inflammation, and boost the skin’s natural defense mechanisms against UV rays.

The idea of drinkable sunscreen might sound futuristic, but it’s rooted in the concept of photoprotection—using antioxidants and other compounds to mitigate the damage caused by UV exposure. Common ingredients in oral sunshields include Nutroxsun, polypodium leucotomos extract, astaxanthin, vitamin C, vitamin E, and beta-carotene, all of which are known for their antioxidant properties.

How Does Internal UV Protection Work?

To understand how oral sun protect works, it’s important to differentiate between internal and external sun protection methods.

• External Sunscreen: The Traditional Approach

Traditional sunscreens create a physical or chemical barrier on the skin’s surface. Physical sunscreens contain minerals like zinc oxide or titanium dioxide that reflect UV rays, while chemical sunscreens absorb UV radiation and convert it into heat, which is then released from the skin.

• Internal Sunscreen: The New Frontier

Oral sunshields, on the other hand, work internally by enhancing the skin’s natural ability to combat UV-induced damage. They don’t block UV rays directly but instead focus on reducing oxidative stress and inflammation caused by sun exposure. Here’s how they work:

1. Antioxidant Boost: Ingredients like astaxanthin neutralize free radicals generated by UV radiation, preventing cellular damage.

2. Anti-Inflammatory Effects: Compounds such as vitamin C and E reduce redness and inflammation associated with sunburn.

3. DNA Repair Support: Some oral sunshields contain nutrients that aid in repairing DNA damage caused by UV exposure.

4. Melanin Production: Certain ingredients may stimulate melanin production, providing a natural tan and reducing the risk of sunburn.

While oral sunshields don’t replace the need for topical sunscreen, they are marketed as a complementary layer of protection.

Types of Oral Sunshield

The market for oral sun protect products is growing, with various formulations catering to different needs. Here are some common types of oral sunshields:

1. A Citrus and Rosemary-Based Oral Sunshield

Nutroxsun is a scientifically formulated oral sun protection ingredient that leverages the power of natural antioxidants, specifically extracts from citrus fruits and rosemary. This formula is designed to combat oxidative stress and inflammation caused by UV radiation, helping to protect the skin from within.

2. Astaxanthin Supplements: A powerful antioxidant derived from algae, astaxanthin is praised for its ability to protect the skin from UV-induced damage.

3. Vitamin C and E Combinations: These vitamins work synergistically to neutralize free radicals and support skin health.

4. Beta-Carotene Supplements: Found in carrots and other orange vegetables, beta-carotene is a precursor to vitamin A and is believed to enhance the skin’s natural defense against UV rays.

Do Oral Sunshields Really Work? What Experts Say

The effectiveness of drinkable sunscreen has been a topic of debate among dermatologists and scientists. While some studies suggest potential benefits, experts emphasize that these products should not replace traditional sunscreen.

Several studies have explored the efficacy of oral sunshields:

- Studies found that rosemary and grapefruit extracts reduced redness and boosts UV tolerance by 30%.

- Research on astaxanthin has shown that it can improve skin elasticity and reduce the appearance of wrinkles caused by sun damage.

- A 2020 review highlighted the potential of oral antioxidants in reducing oxidative stress and inflammation caused by UV radiation.

While these findings are promising, experts caution that oral sunshields should be used in conjunction with, not instead of, traditional sunscreen.

Benefits Of Oral Sunshield

1. Convenience: Unlike topical sunscreen, which needs to be reapplied every few hours, oral sunshields offer long-lasting protection with a single dose.

2. Enhanced Protection: When used alongside topical sunscreen, oral sunshields can provide an extra layer of defense against UV damage.

3. Skin Health: Many oral sunshields contain ingredients that promote overall skin health, such as antioxidants and vitamins.

4. Suitable for All Skin Types: Oral sunshields are ideal for individuals with sensitive skin or those who struggle with the texture or smell of traditional sunscreens.

Limitations of Oral Sunshield

1. Not a Standalone Solution: Oral sunshields do not provide sufficient protection on their own and must be used with topical sunscreen.

2. Delayed Onset: Unlike topical sunscreen, which works immediately upon application, oral sunshields may take several days of consistent use to show effects.

How To Use Oral Sunshield Effectively

1. Combine with Topical Sunscreen: Always use oral sunshields alongside a broad-spectrum SPF 30 or higher sunscreen.

2. Start Early: Begin taking oral sunshields a few weeks before prolonged sun exposure to allow the ingredients to build up in your system.

3. Stay Consistent: For optimal results, take oral sunshields regularly, especially during sunny months.

Conclusion 

The concept of drinkable sunscreen is undoubtedly intriguing, and there’s growing evidence to suggest that oral sunshields can play a role in protecting your skin from UV damage. However, they are not a magic bullet. Experts agree that while oral sunshields can enhance your skin’s natural defenses, they should never replace traditional sunscreen.

If you’re considering trying an oral sunshield, consult with a dermatologist to determine the best product for your needs. And remember, the most effective sun protection strategy involves a combination of topical sunscreen, protective clothing, and avoiding excessive sun exposure.
