3% Niacinamide
Vitamin B3 with multiple skin-supporting functions. At 3%, niacinamide helps support barrier function, improve uneven-looking tone, calm visible signs of irritation and regulate surface oil without acting as a harsh drying treatment.
L-Carnosine
A naturally occurring dipeptide composed of beta-alanine and histidine. Carnosine provides antioxidant support and is particularly interesting in ageing skincare because of its anti-glycation activity. Glycation can affect structural proteins such as collagen and elastin over time, contributing to visible loss of elasticity and skin quality.
Glucosyl Hesperidin
A water-soluble derivative of hesperidin, a citrus bioflavonoid. It is used in skincare to support microcirculation and antioxidant activity, helping promote a healthier-looking, more radiant and even complexion.
Yeast Extract
Included as part of the formula's skin-conditioning and environmental stress-support system. Optiphi describes the product's broader technology in relation to the skin's natural stress response; however, the current INCI lists Yeast Extract rather than a separate ingredient named “Heat Shock Proteins.”
L-Histidine & Beta-Alanine
Amino acids included within the supporting ingredient system. They are also the two amino-acid components from which the dipeptide carnosine is formed.
