Antioxidants neutralise free radicals — unstable molecules that trigger a chain reaction of cellular damage in the skin.

When skin is exposed to pollution, its natural antioxidant defences — squalene and Vitamin E — become rapidly depleted, leading to oxidative stress. The result: dryness, excess sebum, uneven skin tone, and accelerated ageing.

Replenishing antioxidants is essential to interrupt this cycle, protect skin cells from damage, and defend against the long-term effects of pollution and environmental aggressors.

The Pollution Defense Serum is exceptionally rich in antioxidants — particularly Prickly Pear Seed Oil, which contains 2-3x more Vitamin E than other plant oils. This powerhouse ingredient nourishes skin cells, neutralises harmful free radicals, and forms a protective shield against pollution and environmental stress.

Pollution breaks down the skin's collagen and lipid layer, impairing the skin barrier — leading to excess sebum, uneven skin tone, loss of elasticity, and premature ageing.

Fatty acids are essential to rebuilding and maintaining this barrier. The Pollution Defense Serum is exceptionally rich in fatty acids (Omega-3, 5, 6, 7 & 9) — replenishing what pollution depletes, repairing the skin barrier, and stimulating collagen formation for firmer, more resilient skin.

Daily Use
After cleansing and toning (once the mist is about 80% absorbed), warm 1-3 drops in palms to activate the serum. Press evenly onto face, neck, and décolletage. Lightweight and fast-absorbing — no moisturiser needed.

Intensive Massage
Warm 5-8 drops in palms and massage into skin using upward, outward lifting strokes from the centre of the face. Include neck and décolletage for a full lifting effect.

Mask Booster
Mix 1-2 drops into your mask and apply as usual. Use 1-2 times per week for enhanced repair.

Makeup Primer
Mix 1 drop with your foundation for a more seamless, luminous finish.
