Look for SPF (sun protection factor) numbers on the labels of sunscreens. Select an SPF of 30 or higher to prevent sunburn and tanning, both of which are signs of skin damage. Choose a sunscreen that protects against both UVA and UVB rays (usually labeled as a "broad-spectrum" sunscreen).
Sunscreen sprays are convenient but should be used with caution. For starters, sprays are easy to breathe in, which can irritate the lungs. Some sprays also are flammable, so you need to avoid sparks or flames when applying them and wearing them. And, sprays make it hard to tell if you have applied enough sunscreen, which increases the risk of sunburn.
Other things to consider:
- Don't use sunscreens with PABA, which can cause skin allergies.
- For sensitive skin, look for products with the active ingredient titanium dioxide.
- If your teen or preteen wants to use a self-tanner sunscreen, be sure to get one that also has UV protection (many offer little or none).
Babies younger than 6 months should be kept out of the sun. When going outside, dress your baby in lightweight clothes that cover arms and legs — and don't forget a hat. If you can't avoid the sun, you can use a small amount of sunscreen on your baby's exposed skin, like the hands and face.
