Glyco-Guard

Glyco-Guard

Defend your skin’s youthful integrity with Circadia’s Glyco-Guard. An advanced anti-glycation serum formulated to help minimize the visible effects of sugar-induced aging and preserve firmness, radiance, and resilience.

Progressive Benefits

With regular use, the skin appears smoother, more luminous, and visibly firmer. This intelligent treatment helps maintain the look of elasticity and clarity by reducing the visible impact of glycation. A process that contributes to dullness, loss of tone, and fine lines.

Science-Backed Formula

Powered by Circadia’s exclusive Anti-Glycation Peptide Complex featuring Carnosine, a dipeptide that helps counter visible protein cross-linking caused by excess sugar exposure. Blueberry extract and Green Tea polyphenols deliver antioxidant protection, while Acetyl Tetrapeptide-2 supports firmness and structural renewal. Hyaluronic acid and Squalane replenish moisture, balanced at a skin-friendly pH of 5.5-6.0 for maximum performance.

Texture & Ritual

This lightweight, silky serum glides onto the skin and absorbs instantly without residue. Apply morning and evening after cleansing and toning. Dispense 2-3 drops onto fingertips and smooth evenly over the face and neck. Follow with Circadia moisturizer or SPF as desired.
