Why Your Skin Needs a Two-Way Strategy
When it comes to skin cancer prevention and anti-ageing, we often focus solely on what we apply to the surface. However, current dermatological evidence suggests that the most effective way to repair DNA damage and strengthen your skin is a combined approach: Internal Defence + External Barrier.
At Western Skin Institute, we recommend the 'Double B3' Protocol. This strategy utilises Vitamin B3 (Nicotinamide/Niacinamide) in two forms to create a synergistic effect that repairs damage from within while shielding you from the harsh Australian suns.

The Three Pillars of the Protocol
Internal Defence (Nicotinamide 500mg): Taking an oral supplement twice daily enhances your skin’s natural DNA repair mechanisms. This is particularly vital for high-risk patients with previous sun damage, as it helps reduce the formation of actinic keratoses and non-melanoma skin cancers.
Internal Defence (Nicotinamide 500mg): Taking an oral supplement twice daily enhances your skin’s natural DNA repair mechanisms. This is particularly vital for high-risk patients with previous sun damage, as it helps reduce the formation of actinic keratoses and non-melanoma skin cancers.
External Barrier (Niacinamide 10% Cream): Applied every morning, this topical cream reduces inflammation, regulates sebum, and strengthens your skin’s lipid barrier. It’s your first line of defence against UV-induced immunosuppression.
UV Protection: No routine is complete without a high-quality, Broad Spectrum Sunscreen. We recommend La Roche-Posay Anthelios for the face and a generous Broad Spectrum Pump Pack for the body to ensure essential UV defence.
