Benefits

Selected by dermatologist Dr. Alice Rudd, Airy Day Clear as Day SPF50 provides reliable, ultra-lightweight sun protection ideal for daily use. Its dermatologist-approved formula offers superior broad-spectrum UV defence using 100% mineral zinc oxide, combined with calming niacinamide and antioxidant-rich Kakadu Plum to brighten, soothe, and protect the skin from environmental stressors. Non-greasy and fast-absorbing, it seamlessly integrates into any skincare routine, offering daily sun protection without irritation or residue.

Active Ingredients


Zinc Oxide (Mineral SPF50): Provides broad-spectrum UVA/UVB protection; effectively shields skin from sun damage and premature aging.

Niacinamide (Vitamin B3): Calms redness and inflammation; strengthens the skin barrier to enhance overall skin health.

Kakadu Plum Extract: Exceptionally rich in Vitamin C; delivers powerful antioxidant protection and helps to brighten skin tone.

Hyaluronic Acid: Deeply hydrates by locking moisture into the skin; ensures comfort without leaving a heavy or greasy feel.

All Ingredients:
Water (Aqua), Zinc Oxide, Coco-Caprylate/Caprate, Niacinamide, Kakadu Plum Extract, Sodium Hyaluronate (Hyaluronic Acid), Glycerin, Cetearyl Alcohol, Glyceryl Stearate, PEG-100 Stearate, Caprylic/Capric Triglyceride, Polyhydroxystearic Acid, Xanthan Gum, Aloe Barbadensis Leaf Juice, Tocopherol (Vitamin E), Phenoxyethanol, Ethylhexylglycerin, Citric Acid.

How to Use

Each morning, apply generously as the final step in your skincare routine. Smooth evenly onto your face, neck, and décolletage at least 20 minutes before sun exposure. Reapply every two hours or after swimming, sweating, or towel drying.

Pro-Tip from Dr. Rudd:
Ensure thorough protection by applying two finger-lengths of sunscreen—this amount ensures your skin is adequately shielded from harmful UV rays daily.
