iS Clinical Extreme Protect SPF 40

The active ingredients in this sunscreen — Zinc Oxide and Titanium Dioxide — are mineral filters that sit on the skin's surface rather than being absorbed into the bloodstream, making them generally considered safe during pregnancy and breastfeeding. The formula also contains no parabens, phthalates, or sulphates. However, as with any skincare product, we always recommend consulting your GP or midwife before making changes to your routine during pregnancy or whilst breastfeeding.

Yes. Beyond its broad-spectrum UV protection, the formula contains powerful antioxidants derived from Centella Asiatica that stimulate collagen synthesis and support skin healing. Vitamin E provides additional antioxidant defence against oxidative damage, whilst the Extremozyme® technology adds further environmental protection. Consistent daily use helps reduce the risk of photoageing, including fine lines, wrinkles, and uneven skin tone caused by sun exposure.

The Translucent shade provides invisible sun protection with no colour payoff, ideal for those who prefer a completely clear finish. The PerfecTint® Beige and PerfecTint® Bronze shades contain a subtle tint that helps enhance your natural skin tone, blur imperfections, and provide a smooth, even complexion. Choose the shade that best matches your skin tone and desired level of coverage.

Absolutely. The ultra-sheer, fast-absorbing formula creates a smooth, non-greasy base that sits beautifully under foundation and other makeup. If you choose the PerfecTint® Beige or Bronze shade, you may find you need less foundation as the tint helps blur imperfections and even out skin tone on its own.

Yes, the formula is water resistant for up to 40 minutes during swimming or sweating. After this time, or immediately after towel drying, you should reapply for continued protection. During prolonged sun exposure, reapply at least every 2 hours regardless of activity.

iS Clinical Extreme Protect SPF 40 is an excellent choice for sensitive skin. The 100% physical sunscreen actives are non-irritating and non-allergenic, and the formula is free from parabens, phthalates, and sulphates. It's also suitable for post-procedure skin, making it gentle enough for even the most reactive complexions whilst still delivering robust broad-spectrum protection.

Extremozyme® is iS Clinical's proprietary blend of protective enzymes that have been clinically proven to help shield skin from environmental aggressors. This technology goes beyond standard UV protection by providing a multilevel defence against a wider range of environmental stressors that can contribute to premature ageing and skin damage.

No. The formula uses transparent micronised mineral filters specifically designed to provide true transparency on the skin. It absorbs quickly and leaves a lightweight, non-greasy matte finish without the chalky white residue associated with traditional mineral sunscreens. For additional skin tone matching, choose from Translucent, PerfecTint® Beige, or PerfecTint® Bronze shades.

Extreme Protect SPF 40 is a 100% mineral (physical) sunscreen. It uses transparent micronised Zinc Oxide (15.3%) and Titanium Dioxide (1.3%) as its active sun-filtering ingredients, making it suitable for those who prefer to avoid chemical sunscreen filters entirely.
