By the end of this article, you’ll be an expert on sunscreen and on your way to protecting yourself from the sun’s harmful rays. So, let’s dive in. 

What Is the Best Sunscreen – How Does the Best Sunscreens Work?

Sunscreen works by providing a protective barrier on the skin that helps to shield it from the harmful effects of ultraviolet (UV) radiation from the sun. UV radiation consists of two main types: UVA and UVB. These rays can cause damage to the skin, including sunburn, premature aging, and an increased risk of skin cancer.

The best sunscreen contains active ingredients that work in different ways to protect the skin from UV radiation:

  • Chemical Filters: These compounds absorb UV radiation and then release it as heat. They work by converting UV rays into less damaging forms of energy. Common chemical filters include avobenzone, octisalate, octocrylene, and oxybenzone.
  • Physical (Mineral) Filters: These ingredients, such as zinc oxide and titanium dioxide, sit on the surface of the skin and act as a physical barrier. They reflect and scatter the UV rays away from the skin, preventing them from penetrating the skin and causing damage.

When you apply sunscreen, it creates a protective layer on your skin that reduces the amount of UV radiation that reaches the deeper layers. Sunscreen should be applied generously and evenly to all exposed skin areas, including face, neck, arms, and legs, to ensure effective protection.

Sunscreen products are typically labeled with a Sun Protection Factor (SPF) rating. SPF indicates the level of protection the sunscreen offers against UVB radiation. The higher the SPF number, the greater the protection. For example, an SPF 30 sunscreen will block about 97% of UVB rays, while an SPF 50 sunscreen will block about 98%. However, no sunscreen can provide 100% protection.

It’s important to note that sunscreen should be reapplied regularly, especially after swimming, sweating, or toweling off, as these activities can remove the sunscreen from the skin. Also, sunscreen should be used in combination with other sun protection measures, such as wearing protective clothing, seeking shade, and avoiding excessive sun exposure during peak hours (usually between 10 am and 4 pm).

How to Choose the Best Sunscreen

Selecting the right sunscreen is crucial for protecting your skin from the harmful effects of UV radiation. Here’s a breakdown of important factors to consider.  

SPF (Sun Protection Factor)

The Sun Protection Factor (SPF) is a numerical rating that indicates a sunscreen’s ability to shield your skin from the harmful effects of UVB rays. SPF values represent the multiplier of time you can spend in the sun without getting sunburned compared to how long it would take without any protection.

An SPF of 30 blocks about 97% of UVB rays, offering moderate protection. However, it’s important to note that an SPF 50 blocks about 98%, showing only a slight increase in protection. Going higher in SPF might not provide significantly better protection, as no sunscreen can provide 100% protection.

Broad-Spectrum Protection

Sunscreens labeled as “broad-spectrum” protect your skin from both UVA and UVB rays. UVA rays contribute to premature skin aging, while UVB rays cause sunburn. Opting for a broad-spectrum sunscreen ensures comprehensive protection against various types of UV radiation.

Water Resistance

Water-resistant sunscreens maintain their effectiveness even when exposed to water through swimming, sweating, or other water activities. However, it’s crucial to remember that water resistance does not mean waterproof, and regular reapplication is still necessary for continuous protection.

A sunscreen labeled as “water-resistant” can typically maintain its SPF protection for around 40-80 minutes of water exposure. This feature is especially important for those engaging in water-related activities.

Active ingredients

Sunscreens utilize either physical (mineral) or chemical (organic) active ingredients to absorb or reflect UV radiation. Common physical blockers include zinc oxide and titanium dioxide, while avobenzone and octocrylene are common chemical filters.

Zinc oxide provides excellent broad-spectrum protection and is often recommended by dermatologists due to its ability to sit on the skin’s surface, acting as a physical barrier against UV rays.

Skin Type and Sensitivity

Different skin types have unique needs when it comes to sun protection. Dry, oily, and sensitive skin types require tailored formulations to ensure both protection and comfort.

Approximately 60% of people report having sensitive skin. This prevalence highlights the necessity for sunscreens with gentle ingredients to prevent irritation and allergic reactions.

Cosmetic Considerations

Sunscreens now come in various formulations to accommodate different preferences. Matte finishes, non-greasy textures, and suitability for use under makeup are factors to consider.

Expiration Date

Sunscreens have a limited shelf life due to the breakdown of their active ingredients over time. Checking the expiration date before application ensures that the sunscreen maintains its intended effectiveness.

After three years, sunscreens can lose up to 30% of their original effectiveness. This emphasizes the significance of using sunscreens within their recommended timeframe.

Ease of Application

Sunscreens that are easy to apply evenly on the skin offer consistent coverage. Proper application is crucial for achieving the stated level of protection.

In a study, spray-on sunscreens were found to be less effective if not properly rubbed into the skin. This underscores the importance of thorough and even application for reliable protection.

Allergies and Sensitivities

Reading the ingredient list helps you avoid potential allergens or irritants that could trigger adverse skin reactions, especially for individuals with sensitivities.

Dermatitis caused by sunscreen ingredients accounts for approximately 4% of reported cases of allergic contact dermatitis. Checking the ingredient list is crucial for preventing skin irritation.

Recommendations from Dermatologists

Seeking advice from dermatologists or skincare professionals ensures that you make an informed decision regarding the most suitable sunscreens for your skin’s needs.
