Our Consultant Dermatologist, Dr Andrew Markey, recommends daily use of 3 ‘master molecules’: A (Retinol), B (Niacinamide) and C (Vitamin C), plus SPF (in addition to your cleanser, your moisturizer, your serums). This starter kit contains a 30-day supply of each: Niacinamide SuperDrops (to calm), Pure Vitamin C Capsules (to boost radiance), Featherlight UVA/UVB SPF 50 Sunscreen (for the morning), plus our gentle Super Retinol Night Renewal Moisturizer (to renew skin at night).
