The Ultimate Summer Shield: Why We Pair iS Clinical GeneXC & EltaMD
Summer in the city brings two major challenges for your skin: intense UV rays and increased air pollution (smog). While many people rely on sunscreen alone, the most effective way to “age gracefully” is a two-layer defense strategy.
Here is why combining iS Clinical GeneXC Serum with EltaMD Sunscreen is a non-negotiable for your morning routine.
1. The “Double Defense” Against UV and Pollution
Sunscreen is your first line of defense, but it isn’t a 100% fail-safe. Studies show that SPF can leave the skin vulnerable to a percentage of free radicals triggered by UV rays and environmental pollutants (like car exhaust and ozone).
- GeneXC Serum acts as your “safety net.” Its 20% L-ascorbic acid (Vitamin C) neutralizes those free radicals before they can cause cellular damage.
- The Pollution Factor: Urban pollution causes “oxidative stress,” which leads to dullness and breakouts. GeneXC contains Extremozymes®, proprietary enzymes that are clinically proven to protect and help repair DNA, specifically guarding your skin against environmental aggressors.
2. The Anti-Aging Powerhouse: Collagen & Brightening
Aging gracefully isn’t about stopping the clock; it’s about maintaining skin health.
- GeneXC Serum: Vitamin C is essential for collagen synthesis. By using GeneXC, you are actively supporting skin elasticity and firmness while brightening existing sunspots and evening out your skin tone.
- EltaMD: Most EltaMD formulas (like the fan-favorite UV Clear) include Niacinamide (Vitamin B3) and Hyaluronic Acid. Niacinamide reduces redness and the appearance of fine lines, while Hyaluronic Acid ensures your skin stays plump and hydrated.
3. Hydration: The Key to a Radiant Glow
Heat and air conditioning can zap moisture from your skin, making fine lines look deeper and skin look “crepey.”
- Protecting your skin barrier is vital. When your skin is properly hydrated, it functions better as a barrier against external toxins.
- EltaMD sunscreens are known for their lightweight, moisturizing finishes that don’t feel heavy or greasy, even in 90°F heat. They provide that “dewy” look while keeping moisture locked in.
Why They Work Better Together
When you apply GeneXC Serum under EltaMD, you aren’t just layering products; you are optimizing your protection. The Vitamin C makes your sunscreen more effective at preventing photo-damage, and the sunscreen prevents the light-sensitive Vitamin C from degrading.
How to Apply for Best Results:
- Cleanse: Start with a fresh face.
- Treat: Apply 3–4 drops of GeneXC Serum. Let it absorb for a minute.
- Protect: Apply a liberal amount of EltaMD Sunscreen (don’t forget your neck and ears!).
- Repeat: If you’re out in the LA sun, remember to reapply your SPF every two hours.
Pro-Tip: If you are dealing with hyperpigmentation or “break outs” from summer travel, the Zinc Oxide in EltaMD is incredibly soothing and helps calm inflammation while the GeneXC works on the brightening side.
