How to choose a sunscreen
When do I need to wear sunscreen?
Just because it's cloudy outside doesn't mean you can skip applying sunscreen. Even on cloudy days, up to 80% of the sun's harmful UV rays can penetrate clouds, so you're still at risk of getting sunburned. Thin or light clouds may even enhance UV levels, because of the scattering of sun rays. So even if it's not sunny, being in the habit of applying sunscreen every day will help prevent premature aging and skin damage.
Also, the sun emits harmful UV rays year-round, so it’s necessary to apply regardless of the season.
I recommend applying sunscreen every day, 30 minutes prior to going outdoors and reapplying every two hours.
How do I incorporate sunscreen in my daily routine?
I follow Dr Shari Sperling’s advice that, "SPF is the last thing that goes on during your skincare routine." Dr. Sperling recommends applying topical medications or prescriptions, then moving on to your serums and moisturizers. Finally, apply your sunscreen, which should be SPF 30 or higher. By applying your sunscreen as the last step in your skin-care routine, it will act as a shield from the sun.
Keep in mind that even when you have makeup on, if you're going to be outside, you still need to reapply SPF.
How does the sun impact aging?
Sun exposure depletes collagen and collagen is what keeps the skin smooth and firm. It can also dilate blood vessels to give skin a red tone. And it causes the brown pigment in the skin to be more
People generally slather on sunscreen for special outdoor occasions, like heading to the beach or attending a picnic. While sunscreen protects against sunburns and skin cancer, there is another benefit: It helps reduce signs of skin aging.
Evidence shows that using sunscreen every day helps slow down the skin's aging process.
According to one groundbreaking study, people who use broad-spectrum sunscreen on a daily basis experience 24% less skin aging than those who use sunscreen only intermittently.
What type of sunscreen is most effective for protecting my face and preventing anti-aging?
When it comes to sunscreen, broad spectrum sunscreen works best because it protects you from UVB and UVA rays, which means you’re protected from both sunburns and skin cancer.
The American Academy of Dermatology recommends that everyone use sunscreen that offers the following:
Broad-spectrum protection (protects against UVA and UVB rays)
SPF 30 or higher
Water resistance
I use and carry TiZO sunscreen, which is a highly effective, mineral based, sunscreen that offers both UVA and UVB coverage. Next time you visit Faces Clinical Skincare, ask me for a sample!
What if sunscreen makes me break out?
According to board-certified dermatologist Joel Lamm, MD, says chemical filters are known to agitate the skin, but physical sunscreens, also known as mineral sunscreens, are a gentler SPF option for sensitive skin.
"Physical sunscreens work by reflecting the UV rays off skin," he says. These products utilize mineral filters like zinc oxide and titanium dioxide, which are usually gentler than chemical options.
Make sure to carefully read the ingredient list, as some sunscreens are hybrids, meaning they contain both physical and chemical UV filters.
"If you have sensitive skin, it's important to avoid mineral sunscreens that have parabens, phthalates, and added fragrances, as these can cause irritation, redness, and inflammation of the skin," Dr. Lamm adds.
