Fab Tips for Reapplying Sunscreen with a Face Full of Makeup ...

1. Correctly Prep Your Skin with Sunscreen before Applying Makeup

Heidi Waldorf director of laser and cosmetic dermatology at the Mount Sinai Hospital in New York City states that "One of the reasons that the top of the forehead, near the hairline and the sides of the cheeks, jawline, and neck get more sun is because everyone starts their sunscreen (application) in the middle of the face and neck." She recommends to apply and reapply sunscreen to those areas as they can be easily missed.

2. Try a Moisturizer with Built-in SPF

If your skin is on the sensitive side, streamline your product lineup with a multitasking moisturizer, but only sometimes. "In the cooler months, it's acceptable to "cheat" (your sunscreen game) by using a moisturizer with a sunscreen in it instead of two separate products," says Elizabeth Tanzi, founder and director of Capital Laser & Skin Care and associate clinical professor, Department of Dermatology at the George Washington University Medical Center. "When products are asked to multi-task, make sure you are using enough of the product in order to get the SPF on the label."

3. Even Better, Make It a Tinted Moisturizer with SPF

Swap out your heavy foundation for a lighter formula, like a BB cream but with a hint of tint and added SPF. "If you invest the time to find the perfect match for your skin, you are much more likely to use the two products every day, which is a major investment in the long-term health and beauty of the skin," says Tanzi.

4. Finish Your Look with a Setting Spray Packed with Sunscreen

Celebrity makeup artist Mai Quynh sets her clients' red-carpet looks with setting sprays that offer built-in sun protection. "They're clear, so there's no white film, and they go on lightly as a fine mist," she says. Her favorite? The just-launched Kate Somerville UncompliKated SPF 50, which can be spritzed on before, during, and after makeup application. It's also made with hyaluronic acid to hydrate as it shields skin from the sun.

5. Brush It on with Powdered Sunscreen

If you don't want to mess, smudge, or smear your makeup during a mid-day SPF touchup, apply a powder sunscreen to the face. It can be a loose powder or pressed powder formula.

Tanzi recommends the Colorescience Sunforgettable Very Water Resistant Powder Sun Protection SPF 30 it is the "absolute purest form of powder sunscreen with colors that blend with all skin tones. The (sunscreen powder) is an excellent, water-resistant formula that looks like photo-perfect makeup, but is actually a great sunscreen. The powder locks my makeup in place, cuts down on facial oil on a humid day, and provides excellent sun protection."

6. Touch It up with a Compact

If you're not big on powders, whether it's a texture thing or you worry about handbag spillage there is an alternative. The Eau Thermale Avène Mineral High Protection Tinted Compact SPF 50, which comes in two different shades. "It allows you to touch up your makeup and (apply sunscreen) at the same time," says Waldorf. "It's great to keep in your purse, desk, or even car for touchups."
