Sunscreen: Lotion vs. Spray
What is Sunscreen?
Ultraviolet (UV) radiation from the sun can cause painful sunburn and lead to skin cancer. Using sunscreen as part of your daily routine, especially when spending extended time in the direct sun, can help prevent these harmful effects.
Sunscreen Spray vs. Lotion
The key to both sunscreen lotion and spray is applying enough product. With both formats, it is common to use too little, reducing their effectiveness. This is particularly true of sprays. You need to spray each body area for up to six seconds to achieve a similar level of sun protection factor (SPF) as sunscreen lotion.
What Makes an Effective Sunscreen?
Effective sunscreens protect against both UVA (ultraviolet A) and UVB (ultraviolet B) rays. The two types of sunscreens are:
- Chemical: absorbs UV rays before they can penetrate the skin
- Physical: reflects UV rays away from the skin
Sunscreen Spray vs. Lotion: Cons
- Lotion takes longer to apply than sprays
- Lotion is harder to apply to difficult-to-reach areas like the back without help
Can Sunscreen Irritate My Skin?
Certain sunscreens, particularly those that contain fragrance, can cause irritation, rash, and/or allergic contact dermatitis in some people.
Are Both Sunscreen Types Safe to Use?
The FDA regulates sunscreen products as over-the-counter (OTC) drugs, which requires them to be monitored and to have the ingredients determined to be "generally regarded as safe and effective" (GRASE).
Concerns About Flammability with Spray Sunscreen
Many spray sunscreen products contain flammable ingredients, such as alcohol. The FDA notes there have been cases of people applying and wearing spray sunscreen near open flames, catching fire, and suffering significant burns.
Conclusion
Lotion and spray sunscreen are safe and effective when used properly. Lotion is often recommended over sprays because it is easier to make sure enough product has been applied and that the application is even, with no missed spots.
