What's Included:

1. Age Defence - The Everything Day Cream (50ml)

Your ultimate daytime protection against cellular ageing. Deeply nourishing all-day hydration with DNA repair enzymes, antioxidants and encapsulated broad-spectrum SPF50 PA++++.

Lightweight, non-greasy finish - worn alone or under makeup.

2. Night Repair Therapy (Night Cream)

The Science Behind the Duo:

By Day - Age Defence: Encapsulated SPF50 PA++++ shields against future UV damage, while Photolyase and Endonuclease DNA repair enzymes address past UV damage. A polyphenol-rich antioxidant complex of bilberry extract and raspberry seed oil scavenges free radicals. Clinically proven to prevent UV-induced cellular senescence (P21), inflammation (PTGES), and collagen and fibrillin breakdown (MMP1).

By Night - Night Repair Therapy: Bilberry inhibits hyaluronidase, collagenase and elastase to protect healthy cells. Cell-communicating peptides (Palmitoyl Tripeptide-1 & Tetrapeptide-7) increase collagen synthesis. Retinyl palmitate promotes cell turnover. Botanical oils and hyaluronic acid restore the moisture barrier. Published clinical data shows significant increase in collagen and elastin.

How to Use:
