Skin Cancer Awareness Month: Let’s Talk Sunscreen
In honor of Skin Cancer Awareness Month, we’re spotlighting one of the most powerful tools in your skincare routine—sunscreen.
Why the emphasis? Because daily sunscreen use has been shown to reduce the risk of melanoma—a potentially deadly form of skin cancer—by up to 50%. But the benefits don’t stop there. Ultraviolet (UV) rays not only increase your risk of skin cancer but also speed up visible signs of aging, such as fine lines, sunspots, and sagging skin.
Here’s the bottom line: Sun protection should be part of your daily routine, rain or shine. UV rays can penetrate clouds and glass, meaning your skin is still exposed even on overcast days or while driving.
Physical vs. Chemical Sunscreens: What’s the Difference?
Not all sunscreens are created equal. The two main types—physical (mineral) and chemical—work differently and offer distinct benefits:
| Physical (Mineral) | Chemical |
|---|---|
| Contains zinc oxide and/or titanium dioxide | Contains ingredients like avobenzone, oxybenzone, or octinoxate |
| Sits on top of the skin and reflects UV rays | Absorbs into the skin and transforms UV rays into heat |
| Begins protecting immediately upon application | Requires 15–20 minutes to become effective |
| Less likely to irritate—ideal for sensitive or acne-prone skin | Can sometimes trigger irritation, especially in sensitive skin |
| May leave a white cast on the skin | Typically invisible after application |
If your skin is sensitive or prone to acne, mineral sunscreens are generally the better choice.
My Top Mineral (Physical) Sunscreen Picks
ZO Skin Health Broad-Spectrum SPF
A gentle yet effective option, this lightweight mineral sunscreen contains the ZOX12® complex to protect against UVA/UVB, IR-A, and HEV light—making it ideal for sensitive or post-procedure skin.
ZO Skin Health Sunscreen + Primer SPF
This multitasking product offers broad-spectrum protection with a smooth matte finish. It hydrates, acts as a primer, and helps blur imperfections—great under makeup.
Neostrata Daytime Protection Cream SPF 23
Combining PHAs and antioxidants, this anti-aging moisturizer helps reinforce the skin's moisture barrier and boost firmness while providing sun protection.
Why I Recommend Chemical Sunscreens (and When I Don’t)
Chemical sunscreens are favored for their lightweight feel and clear finish, which makes them a popular choice for everyday wear, especially under makeup. However, some chemical ingredients may cause sensitivity—particularly in young children or individuals with skin conditions like eczema or rosacea. In those cases, switching to a physical sunscreen is often the best move.
My Favorite Chemical Sunscreens
Revision Skincare Intellishade TruPhysical Clear SPF 50
A 4-in-1 anti-aging moisturizer with SPF that protects, hydrates, and brightens. Infused with peptides, antioxidants, hyaluronic acid, and vitamin C to support healthy, glowing skin.
Neostrata Skin Brightener Sunscreen SPF 35
This multitasking moisturizer brightens skin tone, fades age spots, and protects against UV damage—thanks to NeoGlucosamine and B-resorcinol.
Exuviance Daily Corrector SPF 35
Ideal for oily or uneven skin, this lightweight formula reduces discoloration and smooths skin texture while offering daily sun protection.
Choosing the Right Sunscreen for You
There’s no one-size-fits-all when it comes to sunscreen. The best product for you depends on your skin type, lifestyle, and personal preferences—whether you need something water-resistant, fragrance-free, or ultra-hydrating.
Regardless of which formula you choose, SPF matters. For most people, SPF 30 is the minimum recommended for daily use, especially if you're spending time outdoors. However, if you have very fair skin, blue eyes, and blonde or red hair—traits associated with Type I skin—you burn easily and don’t tan well. In this case, a higher level of protection, such as SPF 50, is strongly recommended to help shield your skin from sun damage.
And remember: sunscreen isn’t just for sunny days. Make it a daily habit, and your skin will thank you in the long run.
