Trust Me About Sunscreen!
We get it—sunscreen isn’t the most glamorous step in your skincare routine. But trust us: it’s the most important one. At Med 44 Arcadia, we see the long-term effects of sun exposure every day—from premature aging to hyperpigmentation and even skin cancer. Here's what you really need to know about sunscreen.
Mineral vs. Chemical Sunscreens: What’s the Difference?
Sunscreens work by protecting your skin from harmful ultraviolet (UV) rays, but not all sunscreens do it the same way. They fall into two main categories:
Chemical Sunscreens:
These contain ingredients like avobenzone, oxybenzone, and octinoxate. They absorb UV rays and convert them into harmless heat, preventing damage to your skin. Chemical formulas tend to be lightweight and invisible once applied but may irritate sensitive skin or cause allergies in some people.
Mineral (Physical) Sunscreens
These use natural minerals like zinc oxide or titanium dioxide. Instead of absorbing UV rays, mineral sunscreens act as a physical shield by reflecting and scattering the rays away from your skin. They work immediately upon application and are often better tolerated by sensitive skin. Mineral sunscreens are typically considered safer for the environment and are labeled “reef-safe.”
UVA, UVB & Blue Light: What’s the Difference?
Sunlight isn’t just one kind of ray:
UVA rays penetrate deep into the skin, breaking down collagen and elastin—hello wrinkles and sagging.
UVB rays damage the skin's outer layers and are the primary cause of sunburn. Both UVA and UVB rays are linked to skin cancer.
Blue light (from the sun and screens) penetrates even deeper and can cause inflammation, hyperpigmentation, and oxidative stress.
Only a broad-spectrum sunscreen will protect you from all three.
SPF: What Do the Numbers Actually Mean?
SPF (Sun Protection Factor) measures protection against UVB rays:
SPF 30 blocks 97% of UVB rays.
SPF 50 blocks about 98%.
Anything above SPF 50 offers slightly more coverage—but not dramatically so.
The key? Consistent use and reapplication. No sunscreen works if you don’t apply it properly or reapply after two hours, especially when outdoors.
How to Choose the Right One
Here’s what to look for:
- Broad-spectrum (for UVA + UVB protection)
- SPF 30 or higher
- Non-comedogenic (won’t clog pores)
- Mineral-based if you have sensitive skin
Stick with trusted brands or ask your aesthetic provider—we carry medical-grade sunscreens that deliver both protection and skin benefits.
Face vs. Body Sunscreen
Facial skin is more delicate and often more prone to breakouts or irritation, so you want:
- Lightweight, oil-free, and non-comedogenic formulas for the face
- Hydrating or sport-friendly, higher-volume options for the body
Never use thick, greasy body sunscreen on your face—your pores will thank you.
