Oh, for the blissfully ignorant days of tanning with slippery baby oil. Now that we know better, leaving the house without sunscreen — or without “enough” — is cause for a scolding. And that demand for more SPF is being met with sophisticated products that block specific types of rays — and serve at least one additional purpose.

The key to new sun protection products is “broad-spectrum coverage,” or protection against the sun’s burning rays, known as UVB, as well as the so-called aging rays, known as UVA. While UVB rays have an immediately damaging effect, dermatologists say UVA rays penetrate deep into the skin, breaking down collagen, harming the elastic tissue of the skin, and in some cases, causing skin cancer.

“We are at that tipping point with exposure to UVA rays: We know it causes skin cancer,” a dermatologist and professor at Northwestern University Medical School, June Robinson, said.

While consumers traditionally gravitate to products with the highest amount of sunscreen, the availability of products that address specific rays are changing the market, as are dual-use products. These wonder products allow you to moisture, burn fat, and fight wrinkles while soaking up the summer sun. What could be better?

MOISTURIZER PLUS SUNSCREEN

Among the technological advances in sun protection, a milestone is the approval of Mexoryl, a UVA and UVBblocking ingredient recently approved by the FoodandDrug Administration. One product that contains Mexoryl is La Roche-Posay’s Anthelios SX, a combination moisturizer and broad-spectrum sunscreen. (La Roche-Posay, a subsidiary of L’Oreal, recently became available in drug stores after being sold exclusively in dermatologists’ offices.)

“For us, its about superior UVA protection,” La Roche-Posay’s director of medical and media relations, Gene Colón, said.

He described Anthelios as a daily-use facial moisturizer that is “elegant” to the touch. “In terms of the sunscreen, you want something lighter feeling for the face than for the body,” Mr. Colón said. “Your body can take something that’s heavier and may require something thicker. The skin on your face is thinner, it’s probably more sensitive.”

EYE CREAM PLUS SUNSCREEN

Clarins’s Sun Wrinkle Control Eye Contour Care SPF 30 was designed for use around the eyes and promises to block sun and battle wrinkles. “Sunscreen can be very irritating and yet the eye area is one of the most fragile areas and in need of protection,” Clarins’s senior vice president of marketing, Caroline Pieper-Vogt, said. “It’s very high technology sun care,” she said.

ANTI-CELLULITE CREAM PLUS SUNSCREEN

Perhaps one of the most novel sunscreen products to hit shelves is Bliss Spa’s Ray of Hope, an SPF 20 formula that contains sun-activated ingredients designed to fight cellulite. After the cream is applied to the body, the sun activates molecules in the formula containing caffeine, carnitine, and the herb, centella asiatica — all of which fight cellulite.

Though this might encourage ladies to seek out more sun than usual, the product is not designed to encourage extra tanning, according to the director of product and packaging development at Bliss, Damiana Zullo.

“We’re not promoting going out into the sun,” she said. “But if they are going to go out, at least they have this ingredient that will help them be more confident out there.”

FACE SUNSCREEN PLUS BODY SUNSCREEN

Toting around one tube for your face and another for your body can become bulky and confusing. To simplify the matter, L’Oreal Vichy Laboratoires introduced Capital Soleil SPF 15 Sunscreen Cream for Face and Body with Mexoryl. Marketed as a formula that is equally suitable for face and body, the sunscreen blocks both UVB rays and UVA rays.

L’Oreal USA’s director of skin care and sun care, Angelike Galdi, articulated a fear most women know well — that using a standard sunscreen on their faces will cause greasiness and acne. “We’ve taken that into account in the testing of this product,” she said. “It’s basically one-stop shopping. You don’t have to be concerned about having a million products.”

While the skin on the face is thinner than skin on the rest of the body, it is not inherently more sensitive to sun damage. “As far as I’m concerned, it should all be treated the same,” the director of dermatologic surgery at New York-Presbyterian Hospital, Desiree Ratner, said. “It should all have a high SPF with high UVA and UVB protection. I tell everyone to use an SPF 30 or higher.”

But even with the availability of the best sun protection, the best may be no sun at all. “Nobody ever uses the right amount of sunscreen,” Clarins’s Ms. Pieper-Vogt said. “They forget to reapply. They don’t understand that you can’t reapply ad nauseum. You need to get out of the sun sometime.”
