Spray-on sunscreens have become increasingly popular in recent years due to their convenience and ease of use. However, there are important considerations to keep in mind when choosing and using this form of sun protection. In this blog, Dr. Adam Mamelak, dermatologist and skin cancer expert, details the differences between spray sunscreens and other preparations, their popularity, application tips, and safety concerns.
How Spray Sunscreen is Different from Lotions and Creams
Formulation and Application:
- Spray Sunscreens: Delivered in a fine mist, they offer a quick and easy application, especially for hard-to-reach areas.
- Lotions and Creams: These require manual application, which can ensure a more thorough and even coverage but can be time-consuming.
Absorption:
- Sprays tend to dry quickly and are less likely to leave a greasy residue compared to creams and lotions.
Coverage:
- Sprays can sometimes be less reliable in terms of even coverage, as it can be difficult to see where the product has been applied.
Popularity of Spray Sunscreens
Convenience:
- The primary appeal of spray sunscreens is their convenience. They are easy to apply on the go, especially at the beach or during outdoor activities.
- They are particularly popular among parents, as applying sunscreen to children can be quicker and less of a hassle with sprays.
Preferred Groups:
- Active Individuals: Athletes and outdoor enthusiasts often prefer sprays for quick reapplication during activities.
- Parents: Parents appreciate the ease of spraying sunscreen on squirming children.
- People with Mobility Issues: Those who find it difficult to apply creams or lotions evenly over their bodies might find sprays easier to use.
- Unique areas: spray sunscreen can get hard to reach areas, like your back, and the top of your head where your hair parts.
Sun Protection Levels and Application Tips
Protection Levels:
- Studies have shown that spray sunscreens can provide adequate protection if applied correctly. However, there is a risk of under-application, which can lead to inadequate sun protection.
Application Tips to Ensure Proper Sun Protection:
- Shake Well: Always shake the bottle well before use to ensure the ingredients are properly mixed.
- Apply Generously: Spray until an even sheen appears on the skin. It’s important to use enough product to cover all exposed areas thoroughly. Dr. Mamelak recommends a double application with spray sunscreens to ensure adequate coverage. That is, spray the same area a second time, after the first application has been rubbed in and has dried.
- Rub It In: After spraying, use your hands to rub the sunscreen into your skin to ensure even coverage.
- Avoid Inhalation: Spray sunscreen should be applied in a well-ventilated area to avoid inhaling the mist. Spray it onto your hands first before applying to your face.
- Reapply Regularly: Like other sunscreens, reapply every two hours or immediately after swimming, sweating, or towel drying.
Safety Concerns with Spray Sunscreens
Inhalation Risks:
- There are concerns about the potential risks of inhaling spray sunscreen, which can be harmful, especially for children. Applying in a well-ventilated area and avoiding spraying directly on the face can mitigate this risk.
Flammability:
- Spray sunscreens are often alcohol-based, making them flammable. Avoid using them near open flames, grills, or while smoking.
Environmental Impact:
- Aerosol sprays can have an environmental impact due to the propellants used. Choosing products that minimize environmental harm or opting for pump sprays can be a better choice.
Conclusion
Spray-on sunscreens offer a convenient and effective way to protect your skin from harmful UV rays when used correctly. Their ease of use makes them popular among various groups, especially active individuals and parents. However, it’s crucial to apply them properly to ensure adequate coverage and sun protection. Be mindful of safety concerns, such as inhalation risks and flammability, and always follow best practices for application. With these considerations in mind, spray sunscreens can be a valuable addition to your sun protection routine.
