Protect Your Glow: Why SPF 50 Is Your Skin’s Best Friend This Summer

May is Skin Cancer Awareness Month…so let’s talk SPF!

At Refine Aesthetics Medical Spa in Lawrenceburg, TN, we believe that the first step to achieving healthy, radiant skin is protecting it—every single day. And with May being Skin Cancer Awareness Month, there’s no better time to talk about your skin’s best defense: sunscreen.

Meet Obagi Sun Shield™ Broad Spectrum Sunscreens
We proudly carry four Obagi Medical Broad Spectrum SPF 50 sunscreens, each designed to defend your skin from sun damage while meeting different skin needs. These high-performance formulas protect against UVA and UVB rays—and two of them go even further by also guarding against infrared (IR) and high-energy visible (HEV) light.

Let’s break it down:

What are UVA, UVB, IR, and HEV Rays—and Why Should You Care?

  • UVA Rays are the “aging” rays. They penetrate deep into the skin and are responsible for wrinkles, fine lines, and sunspots. They’re around all year—even on cloudy days.

  • UVB Rays are the “burning” rays. These affect the skin’s surface and are the primary cause of sunburn. They're strongest in the spring and summer months.

  • Infrared (IR) Rays penetrate even deeper than UVA, affecting the skin’s supportive structures and accelerating aging by breaking down collagen.

  • HEV (High-Energy Visible) Light, also known as blue light, is emitted by screens (phones, computers, tablets) and fluorescent lights. It contributes to hyperpigmentation, inflammation, and premature aging.

Yes, even scrolling your phone can affect your skin health. That’s why protection needs to be an all-day, every-day routine—not just a beach-day thing.

Our 4 Obagi SPF 50 Sunscreens at Refine Aesthetics

  1. Sun Shield Matte SPF 50
    Perfect for normal to oily skin, this one gives a smooth, shine-free finish that’s ideal under makeup. It blends easily and won’t leave a white cast.

  2. Sun Shield TINT SPF 50 – Warm or Cool Tint
    This multitasking sunscreen offers both broad spectrum UV protection and defense against IR and HEV rays. Plus, it provides a subtle tint to even out skin tone and give a natural glow—great for days you want to go makeup-free.

  3. Sun Shield Mineral SPF 50
    This is a physical (or mineral) sunscreen—meaning it sits on top of the skin and reflects UV rays instead of absorbing them like chemical sunscreens. It's made with clean ingredients, gentle on sensitive skin, and safe for expecting mamas. A go-to for anyone seeking a non-toxic, no-fuss SPF.

  4. Sun Shield Broad Spectrum SPF 50 Original
    Lightweight, fast-absorbing, and sheer—this classic option is perfect for all skin types and daily wear. It delivers dependable UV protection with a breathable feel.

Why Broad Spectrum Matters
All of Obagi’s sunscreens are “broad spectrum,” which means they protect against both UVA and UVB rays—crucial for preventing premature aging, pigmentation, and, most importantly, skin cancer.

At Refine Aesthetics Medical Spa, we want you to feel confident in your skin—and safe under the sun. Whether you’re shopping for a clean mineral sunscreen or one that multitasks with HEV protection, we’ll help you find the right match for your lifestyle.
