Skinceuticals Daily Sun Defense SPF 20 Mode of Action

Ultra-fine zinc oxide reflects and encapsulated octinoxate absorbs the broadest gamut of carcinogenic and aging UVB and UVA radiation, responsible for photoaging.

If used as directed, provides up to 40% protection against photoaging.

Skinceuticals Daily Sun Defense SPF 20 Instructions for Use

Apply as the last step of any skincare routine (before any make-up).

For increased photoprotection, apply after photoprotective antioxidants, such as those available in Skinceuticals Serums and Corrective Moisturizers.

Diverse topical antioxidant use is preferred over single antioxidant use.

Application after Skinceuticals C E Ferulic provides approximately 90% complete protection against photoaging.

To be effective, the product must be applied generously — you should aim to use 90 mL every 45 days or so.

Skinceuticals Daily Sun Defense SPF 20 Advanced Usage

Enhance the tone and wear of the sunscreen by resurfacing the skin with a product such as Skinceuticals Intense Line Defense or Jan Marini Bioglycolics, and by moisturizing underneath with sodium hyaluronate.

For enhanced photoprotection, reapply once daily (around midday), or brush the skin with a powdered sunscreen brush such as IS Clinical SPF 20 Powder Micronised Physical Sunscreen Brush.

Skinceuticals Daily Sun Defense SPF 20 Notes on Extended Use

Apply in the same manner to the hands, ears and all sides of the neck for the same photoprotective effect.

The water-resistant sunscreen Skinceuticals Sports UV Defense SPF 45 is usually preferable for use on hands.

Skinceuticals Daily Sun Defense SPF 20 Contraindications to Use

None — chemical encapsulation generally prevents sunscreen allergy in prone individuals and protects healthy individuals from developing sensitivities.
