Why it works
Formulated for: under-eye bags, dark circles, puffiness.
iActive Caffeine WS at 5%, encapsulated to stay fully dissolved and deliver active caffeine to the micro-capillaries behind dark circles and puffiness.
The key active in Eyeliss, a clinically studied under-eye peptide complex that enhances lymphatic circulation to reduce fluid retention and under-eye bags. Clinical data: improvement in under-eye bags for 70% of participants after 56 days.
Gleditsia Sinensis Fruit Extract, a honey locust seed-derived active used by premium brands. At 3% it gives a visible tightening effect within minutes of application.
Palmitoyl Pentapeptide-4 signals collagen production and improves periorbital firmness, paired with low and high molecular weight Sodium Hyaluronate for immediate surface plumping and deeper hydration.
Where the DCX Eye Cream provides daily moisturising treatment, the serum delivers concentrated multi-active treatment. Apply serum first, cream second. 30ml · 30-day supply · all skin types.
The DCX Eye Serum delivers concentrated multi-active treatment: iCaffeine at 5%, Dipeptide-2 at 4%, Palmitoyl Peptide Complex at 5%, and Inst'tight for near-instant results. A more targeted serum for those who want a higher-potency treatment approach.
Dipeptide-2 at 4% is the primary functional active for reducing under-eye bags and puffiness. It enhances lymphatic drainage — the mechanism by which morning puffiness accumulates and dissipates. It is the key active in the Eyeliss complex, with clinical studies showing under-eye bag improvement for 70% of participants after 56 days.
Apply the serum, wait five minutes: the eye area visibly firms. This provides an immediate cosmetic lift that sets expectations correctly from the very first use, while the deeper biochemical actives build over days and weeks.
Application
Apply a small amount to clean, dry skin.
Tap gently around the orbital bone and under-eye area with the ring finger — never rub.
Use morning and evening. For best results, apply before heavier creams or moisturisers.
Timeline: Inst'tight tightening visible within 5 minutes. iCaffeine dark circle improvement builds over 14–28 days. Dipeptide-2 puffiness reduction builds over 7–56 days.
*Clinical data relates to the Dipeptide-2 (Eyeliss) active, not the finished formula.
