How Much Sunscreen You Should Actually Apply
As for how much you should apply, Michael Swann, MD, dermatologist in Springfield, Missouri, points out that most people don't apply nearly enough sunscreen to provide the SPF protection on the label, so more is always better. "Studies show people put about one-third of the sunscreen necessary to give them the protection listed on the label (SPF 45), which results in them getting much less protection than they expect they should get," he says.
In the summer, you usually need about a shot glass worth of sunscreen per side of your body, says Patel. "In the cooler months with more clothing on for more protection, it is important to apply a quarter size amount to your face, hands and any other sun-exposed areas," she says. Since so many people don't apply enough sunscreen, Sarkar usually recommends applying one layer and then a second layer.
And yes, you should still apply sunscreen even if you spend the majority of your time indoors. "With respect to windows, glass only filters shorter wavelength UVB rays," says Batra. "However, UVA rays, which have a longer wavelength and penetrate more deeply, can still pass through glass." That's why Batra says people who spend a lot of time in the car often have more signs of sun damage on the skin on their window side. Patel adds that sunscreen will also help protect your skin from damaging blue light radiation from computers and devices.

Why You Should Pay Special Attention When on a Winter Getaway
Are you a snow bunny come wintertime? You need to pay extra attention to sun care while skiing or snowboarding. "Winter sports like skiing and snowboarding combine the dry air of high altitudes with intense sun exposure," says Schlessinger. "Dry, compromised skin is even more susceptible to sun damage, which means it's even more important for these athletes to use an effective sunscreen." Look for a high-SPF, broad-spectrum, water-resistant sunscreen, suggests Schlessinger, and don't overlook your lips. "The lips are easily forgotten when it comes to sunscreen application, but with the dry winter air, you'll also want a lip balm that offers sun protection," says Schlessinger.

How to Find a Sunscreen You Love
Consistently applying sunscreen is a whole lot easier if you have a sunscreen you enjoy using. Everyone's skin is different, so it may take some trial and error for you to find your perfect SPF match. "Take some time to test different products to find a consistency and color you like and will feel comfortable wearing every day," says Batra. "No matter what a product says on the label, it has to agree with your individual skin or you'll never use it."
Of course, you already know that choosing one that's broad-spectrum with an SPF of no less than 30 is an absolute must. Schlessinger suggests selecting a sunscreen that's non-comedogenic, meaning it won't clog pores and cause breakouts. This is especially useful if you have oily or acne-prone skin.
For sensitive skin, Swann says the fewer ingredients in a sunscreen formula, the better. "Look for mineral ingredients like zinc oxide and titanium dioxide," he says. Also look for sunscreens that are free of fragrances if you have sensitive skin, since these can be irritating, says Batra. For those with darker skin tones, using a tinted sunscreen may help you avoid any white residue, adds Batra.
Your skin may have different needs when it's colder outside. "During the winter, it is important to moisturize and keep skin hydrated since the cold tends to dry out skin, even oily skin," says Paul Dean, MD, dermatologist in San Diego. "So looking for a sunscreen that has moisturizing properties such as hyaluronic acid is important."

Why You Shouldn't Multitask Your Sun Protection
What you don't want to do is rely on makeup with SPF as your only form of sun protection. "The problem with multitasking products is that people often don't apply a sufficient amount to achieve the SPF on the label," says Batra. That being said, if you do apply enough product, a multitasking foundation with SPF should be a viable option during the colder months of the year, says Batra. "However, in general, it is more effective to use a separate sunscreen after moisturizing and before applying makeup," she adds.
