iS Clinical Extreme Protect SPF 30™

Extreme Protect SPF 30 is widely regarded as one of the most effective treatment sunscreens available. Unlike standard SPFs that only block UV rays, this formula actively delivers antioxidant protection through its proprietary Extremozyme® technology, Centella Asiatica, and Olive Leaf Extract. These ingredients work together to defend against environmental stressors whilst hydrating the skin and helping to reduce the appearance of fine lines and wrinkles with continued use.

No. Despite containing Zinc Oxide (a mineral sunscreen active), the microfine formulation absorbs smoothly without leaving a white cast or chalky residue. Many users describe the finish as a natural, healthy-looking glow rather than a heavy or greasy feel, making it an excellent base for makeup or to wear on its own.

Yes. Extreme Protect SPF 30 is formulated with Vitamin E and Aloe to deliver lightweight yet effective hydration alongside its sun protection. Many users find it provides enough moisture to replace their morning moisturiser entirely, particularly during warmer months. Simply apply over your treatment serum as the final step in your morning routine. If you have very dry skin, you may wish to layer it over a hydrating moisturiser.

Extremozyme® is iS Clinical's proprietary blend of enzymes that are clinically proven to help defend the skin against the visible effects of environmental stressors. This includes protection from temperature extremes, arid climates, pollution, and other environmental aggressors that go beyond UV damage. It works alongside the sunscreen actives to provide a comprehensive multi-level defence system for your skin.

Yes. Extreme Protect SPF 30 is well-suited for sensitive skin. The formula contains soothing ingredients such as Aloe Vera, Olive Leaf Extract, and Centella Asiatica, which help calm irritation and reduce redness. It is also paraben free, phthalate free, and hypoallergenic. Many users with sensitive skin and rosacea report that it soothes their skin whilst providing reliable protection without causing breakouts or irritation.

You should reapply at least every 2 hours for continuous protection, and more frequently if you are swimming, sweating, or towel drying. Apply the initial layer liberally at least 15 minutes before sun exposure to allow the formula to fully absorb and activate. Remember that most people under-apply sunscreen, so be generous with the amount you use.

Absolutely. Extreme Protect SPF 30 is an excellent choice for mature skin. It combines broad spectrum sun protection with anti-ageing benefits including antioxidant support from Centella Asiatica and Vitamin E, which help maintain a more youthful-looking complexion. With continued daily use, it helps improve the appearance of fine lines and wrinkles whilst keeping skin hydrated and protected from further photodamage.

Yes. Extreme Protect SPF 30 is widely recommended by skincare professionals for post-procedure use. Its gentle, hydrating formula with soothing botanicals helps comfort and protect compromised skin whilst providing essential UV defence during the healing period when skin is at its most vulnerable. Always follow your practitioner's specific aftercare advice.

iS Clinical considers Extreme Protect SPF 30 to be pregnancy and nursing safe. However, this formula does contain Octinoxate (5.50%), a chemical UV filter that some healthcare providers advise avoiding during pregnancy as a precaution due to potential hormonal activity. The Zinc Oxide component is widely regarded as safe during pregnancy. If you have any concerns, consult your midwife or GP before use. For a purely mineral sunscreen alternative, speak to your skincare professional about options containing only Zinc Oxide or Titanium Dioxide.
