Light Day Sunscreen Broad Spectrum SPF-37
If there’s one skincare step that changes everything, it’s sunscreen — but finding one that feels good and works? That’s another story. Most sunscreens are heavy, chalky, or make you feel like you’re wearing a mask.
That’s why we love Circadia’s Light Day Sunscreen Broad Spectrum SPF 37. It’s the daily SPF that actually feels good — hydrating, breathable, and makeup-friendly. Whether you’re running errands in Springfield, enjoying time outdoors, or just sitting near a sunny window, this sunscreen protects your skin without clogging pores or leaving a white cast.
What Circadia Says About It
Circadia Light Day Sunscreen Broad Spectrum SPF 37 provides broad-spectrum protection from both UVA (aging) and UVB (burning) rays using a combination of physical and chemical filters. It’s specifically formulated to protect the skin from environmental damage while keeping it hydrated and comfortable.
The lightweight formula absorbs quickly, making it ideal for daily use — even under makeup. Circadia designed it to defend against premature aging, hyperpigmentation, and loss of elasticity while maintaining the skin’s moisture balance.

Key Ingredients and How They Work
Circadia’s sunscreen isn’t just a shield — it’s skincare. Each ingredient plays a role in keeping your skin protected, hydrated, and radiant. It blends modern sunscreen technology with skin-loving ingredients that support your barrier instead of stressing it.
| Ingredient | What It Does | How It Helps Your Skin |
|---|---|---|
| Zinc Oxide & Octinoxate | Reflect and absorb UV rays | Provide full UVA/UVB protection without heaviness |
| Squalane | Lightweight moisturizer | Keeps skin soft and hydrated all day |
| Aloe Vera Extract | Calms and soothes | Reduces redness and irritation from sun exposure |
| Vitamin E (Tocopherol) | Antioxidant defense | Helps prevent environmental and sun damage |
| Panthenol (Provitamin B5) | Repairs and hydrates | Keeps skin balanced and comfortable |
In short: Circadia’s Light Day Sunscreen SPF 37 gives your skin hydration, antioxidant protection, and broad-spectrum coverage — all in one weightless formula.
Why Our Clients Love it
Our clients rave about how this sunscreen feels on their skin — lightweight, non-greasy, and zero residue. It blends beautifully under makeup or can be worn solo for a fresh, natural finish.
It’s especially loved by those who’ve struggled with sunscreens that cause breakouts or irritation. With this one, skin stays calm, balanced, and protected — even for acne-prone or sensitive skin types.
And because it’s not thick or heavy, it’s perfect for year-round use — from summer sunshine to those winter drives where sunlight still hits through the windshield.
How to Use It Safely & Effectively
- Apply as the final step in your morning skincare routine, after moisturizer or before makeup.
- Use a nickel-sized amount for the face and neck — don’t skimp!
- Reapply every two hours if you’re outdoors, sweating, or swimming.
- Use daily, rain or shine — UV rays are sneaky and can penetrate clouds and windows.
Pro Tip: Don’t forget your ears, neck, and the backs of your hands — they show sun damage first and often get overlooked!
Perfect Pairings for Your Best Results
To enhance protection and overall skin health, we recommend pairing this SPF with:
- Vitamin C Reversal Serum – Boosts antioxidant protection and firmness.
- Aqua-Biotic Balancing Moisturizer – Strengthens your barrier for smoother makeup application.
- Licorice & Bearberry Brightening Mist – Adds hydration and radiance throughout the day.
Used together, these create a daily routine that defends, hydrates, and nourishes your skin — so you stay radiant, protected, and confident.
