How to Choose the Right Sunscreen Lotion

Sunrays contain UV A and UV B rays. Both of these are harmful and you should always be conscious to protect your skin against the negative effects from these UV rays. Applying sun screen lotion is one way of protecting your skin against the harm. Thus, sunscreens find an important place in our daily skin care routine. Not only when we need to step out in the sun, but they are preferably used on daily basis for maximum effect.

The SPF (Sun Protection Factor) indicates a product’s effectiveness against sunburn-causing UVB rays. If a bare-skinned, fair person reddens in four minutes, an SPF 30 ups that time to 120 minutes (the simple math, 4 x 30 = 120). The ratings have been around for decades, but in recent years, there’s been a lot of action on the high end, with an SPF of 70 hitting the market in 2007 and an SPF of 100+ becoming available in 2009.

There is no total sunblock claim. If you see such a claim, now considered “false or misleading” by the FDA, it’s either an old product or an old packaging, or it could be on a product from a smaller company. They have been granted an extra year to make the label changes.

Look for an SPF of 30. That should be plenty for most people outdoors, although though some dermatologists advise that patients who have had skin cancer or other conditions go with a higher SPF. You will need to reapply every two hours.

Real aging protection. For protection against skin cancer and damage that leads to wrinkles and age spots, you need a sunscreen that also shields against UVA rays. These reach deeper layers of your skin, disrupting its immune system and causing genetic changes that can lead to cancer.

Labels that tell you if you’re getting adequate UVA protection. The key words are “broad spectrum.” Before this year, that claim meant only that the product contained an ingredient that provided some UVA protection. Now it tells you that the sunscreen has been tested to prove it works against UVA rays.

Look for “Broad spectrum” and an SPF of at least 15. A broad-spectrum SPF 30 product must have more UVA protection working in tandem with SPF, so a broad-spectrum SPF 30 product must have more UVA protection than a broad-spectrum 15 one. Below SPF 15, no product can claim to protect against cancer or early aging.

Also, check out the now-required drug facts box. Broad-spectrum sunscreens that are SPF 15 and higher get bragging rights — “If used as directed with other sun-protection measures, this product decreases the risk of skin cancer and early skin aging caused by the sun.” Those that don’t meet the standard’s labels must read, “Skin Cancer/Skin Aging Alert: Spending time in the sun increases your risk of skin cancer and early skin aging. This product has been shown only to help prevent sunburn, not skin cancer or early skin aging.”
