iS Clinical Extreme Protect SPF 40 | All-Physical Mineral Sunscreen with Extremozymes

Sun protection elevated to a treatment step. Extreme Protect SPF 40 is iS Clinical's most comprehensive daily mineral sunscreen, combining transparent micronised Zinc Oxide and Titanium Dioxide with the brand's proprietary Extremozyme technology to provide broad-spectrum UVA and UVB protection alongside antioxidant defence and skin health support in a single elegant application.

The Extremozymes are what make it genuinely different from a standard SPF 40. Clinically proven to protect and repair skin proteins and DNA from environmental stress, they provide a second layer of protection beyond the physical UV filters.

Who is Extreme Protect SPF 40 best for?

• Anyone wanting the most comprehensive daily mineral SPF in the iS Clinical range
• Post-procedure skin where a pure mineral, all-physical SPF is essential during recovery
• Sensitive, rosacea-prone and reactive skin that cannot tolerate chemical SPF filters
• Those wanting antioxidant and environmental protection alongside their sun protection
• A final morning step in any iS Clinical routine

Key ingredients and why they matter

• Transparent micronised Zinc Oxide and Titanium Dioxide: All-physical mineral UV filters that provide broad-spectrum UVA and UVB protection without chemical absorption, suitable for all skin types including the most sensitive and post-procedure skin
• Extremozymes (proprietary enzyme complex): Clinically proven to protect and repair DNA and proteins in the skin from environmental stress, adding a second layer of protection beyond the physical UV barrier
• Vitamin E: Antioxidant that supports skin health and works synergistically with the SPF and Extremozyme protection
• Centella Asiatica: Healing botanical that supports barrier integrity and calms inflammation throughout the day

How we use Extreme Protect SPF 40 at Face for Soul

As a pharmacist prescriber specialising in skin health, Extreme Protect SPF 40 is the iS Clinical SPF I recommend most consistently as a daily final morning step. The all-physical formula makes it the appropriate choice for post-procedure patients and anyone with sensitive or reactive skin. The Extremozyme content gives it a clinical depth that standard mineral SPFs at this price point do not have.

Complete your iS Clinical morning routine

Apply Extreme Protect SPF 40 as the final step in your morning routine, after your iS Clinical serum and moisturiser. It sits comfortably under makeup and provides all-day protection without the white cast of older mineral formulas.

Frequently Asked Questions

Does it leave a white cast?
No. The micronised, transparent mineral filters are specifically formulated to minimise white cast. Suitable for most skin tones worn alone or under foundation.

Is it suitable post-procedure?
Yes. The all-physical mineral formula is the preferred SPF type for post-procedure skin where chemical filters may cause sensitivity or irritation. Always follow your clinician's advice on when to restart SPF.

How does it differ from Extreme Protect SPF 30?
SPF 40 provides higher UV protection and includes all-physical transparent micronised filters alongside Extremozymes. SPF 30 uses microfine Zinc Oxide with microencapsulated organic actives. SPF 40 is the preferred choice for post-procedure and sensitive skin; SPF 30 suits daily general use. Both deliver broad-spectrum protection with Extremozyme technology.

Is iS Clinical cruelty-free?
Yes. iS Clinical does not test on animals.

Is it vegan?
iS Clinical formulates without animal-derived ingredients in the majority of its products.
