It's Almost Fall! Time to Shelf Your Sunscreen?

By Dawn Morris, MS, APN, FNP-C  ·  September 10, 2019

Autumn is just around the corner. Days grow shorter, the air is crisper, and there is pumpkin spice flavor in everything. Time to skip the sunscreen? No. Sunscreen is a year-round necessity. The American Academy of Dermatology recommends daily sunscreen use, and research consistently shows that patients treating signs of aging and hyperpigmentation achieve better results when their daily routine includes sunscreen. Use a broad-spectrum formula with at least SPF 30, applied 15 minutes before sun exposure, to prevent skin cancer, premature aging, wrinkles, and hyperpigmentation.

How Much Is Enough?

When considering skincare, sunscreen is the first and most important ingredient for healthy, youthful skin. An ounce of prevention is worth a pound of cure -- and in the case of sunscreen, an ounce (a full shot glass-sized amount) is literally the amount needed to cover the entire body effectively. While a change in season and wardrobe may mean less surface area to cover, the face, neck, and décolleté should never be skipped in cooler months. At least a teaspoon-sized amount should be applied daily, because the sun shines year-round and 80% of UV rays penetrate skin even on cloudy days.

Fall and winter are also the ideal times to complete chemical peels and microneedling treatments -- and sunscreen is essential to protect vulnerable skin after those procedures.

Chemical vs. Physical Sunscreen

There are two basic types of sunscreen. A chemical sunscreen absorbs UV rays while a physical sunscreen deflects them, shielding the skin. Physical sunscreens are often tinted to avoid a white residue; chemical sunscreens are typically easier to rub in. Which is better? The one you will actually use every day.

Addressing the Objections

"There's enough sunscreen in my foundation."

Foundation SPF is a helpful addition but not sufficient on its own. It is typically not applied to the neck and décolleté, and you rarely apply the full teaspoon-sized amount needed for full protection. Use a dedicated sunscreen underneath.

"Sunscreen makes me break out."

Some breakouts can occur when sunscreen is first introduced, but the skin often adjusts within a few weeks. Look for formulas that are non-comedogenic (won't clog pores) or designed specifically for the face. Keep trying until you find one that works for you.

"I don't go outside during the day."

UV rays come through windows. Indoor exposure still accumulates over time.

"Sunscreen causes cancer."

Claims that sunscreen ingredients are toxic have not been supported by medical research. If you are concerned about specific ingredients, choose a physical formula with zinc oxide and/or titanium dioxide. As long as your sunscreen is broad-spectrum, water-resistant, and SPF 30 or higher, it will protect your skin.

"I don't want to block my Vitamin D."

Vitamin D production from sun exposure is inconsistent even without sunscreen. Those with concerns should ensure adequate Vitamin D through diet or supplementation, and discuss any deficiency with their healthcare provider.
