This spray-on sunscreen has an SPF rating that’s overkill to the max. There isn't enough sunlight in a day anywhere in the world to merit even an SPF 50, let alone SPF 100. And even sunscreens with these extra-high SPF ratings must be reapplied throughout the day to maintain protection—don't use this thinking that since it's SPF 100, you can apply it once and forget about it for the rest of your day outside because, if you've been sweating or rubbing at your skin, you will need to reapply.
Although this sunscreen provides sufficient UVA protection with stabilized avobenzone, the fragranced formula's main ingredient is alcohol, and that's a problem. The alcohol allows this spray to feel light and dry quickly, but it also poses a risk of irritation with each use (see More Info). Because the amount and type of sunscreen actives used have their own sensitizing potential, adding alcohol to the mix only fuels a possible fire.
The film-forming agent this contains supports Coppertone’s water-resistant claims (technically, it should be labeled "very water-resistant" because they're claiming 80 minutes of protection in water; the "water-resistant" claim indicates 40 minutes of protection—we know, confusing, but that’s the regulation according to the FDA). The teeny amount of antioxidants this contains is wasted as the alcohol negates any of the benefits those provide.
- Provides broad-spectrum sun protection in a convenient spray format.
- Very water-resistant.
- Contains antioxidant vitamins.
- High amount of alcohol puts skin at risk of irritation.
- Alcohol combined with the amount of sunscreen actives increases their potential to be sensitizing.
Alcohol in skin-care products causes dryness and free-radical damage, and impairs the skin's ability to heal. The irritation it causes damages healthy collagen production and can stimulate oil production at the base of the pore, making oily skin worse (Sources: "Skin Care—From the Inside Out and Outside In," Tufts Daily, April 1, 2002; eMedicine Journal, May 8, 2002, volume 3, number 5, www.emedicine.com; Cutis, February 2001, pages 25–27; Contact Dermatitis, January 1996, pages 12–16; and http://pubs.niaaa.nih.gov/publications/arh27-4/277-284.htm).
