Circadia Light Day Sunscreen SPF 37 is a lightweight, non-comedogenic daily sunscreen designed for acne-prone and sensitive skin. Unlike traditional SPF formulas that leave a white cast or feel heavy, this advanced chemical sunscreen absorbs completely clear while delivering triple antioxidant defense, DNA protection, and blue light support. More than just UV coverage, it functions as an anti-aging daytime treatment — synchronizing with your skin’s circadian rhythm to defend against environmental stress, pollution, and premature aging.

• Circadia Light Day Sunscreen SPF 37 is suitable for all skin types, including sensitive and acne-prone complexions. Its non-comedogenic formula is specifically designed to reduce inflammation that can often trigger blemish flares.
• This product is the perfect choice for individuals looking for "lifestyle" protection, meaning it is designed for daily office, home, and outdoor errand use rather than heavy sports. It is especially beneficial for those concerned with anti-aging, as it proactively protects the skin's structural integrity.
• Because of its fast-absorbing, lotion-like texture, it is a favorite for those who dislike the "heavy" or "greasy" feel of traditional sunscreens. It doubles as an excellent primer for makeup, providing a smooth, hydrated canvas.

We recommend applying this as the final step in your morning routine.

• For dry or dehydrated skin: Layer over AquaPorin Hydrating Cream to seal in moisture while adding a protective shield.
  
• For oily or acne-prone skin: This lightweight lotion provides enough hydration to function as your primary daytime moisturizer, simplifying your routine without clogging pores.
  
• For maximum defence: Apply 15 minutes after your Vitamin C Reversal Serum to create a complete antioxidant and UV barrier.

Follow these steps to ensure your skin is fully protected and synchronized with its daytime defense phase.

• Final Step: Apply in the morning as the last step of your skincare regimen.
  
• Amount: Use a nickel-sized amount for the face and neck.
  
• Application: Spread evenly over the face, neck, and chest. Allow it to absorb fully before applying makeup.
  
• Consistency: Use every single day, even when it is cloudy or you are staying indoors, to protect against incidental UV and blue light exposure.
