DERMAQUEST MelaQuest Cysteamine Serum

DERMAQUEST MelaQuest Cysteamine Serum

Powerful serum against melasma and stubborn pigment spots

When regular brightening products no longer deliver results, the skin requires a higher-level approach. Stubborn melasma, deep pigment spots, and post-inflammatory discolorations often respond only to clinically proven active ingredients that work on multiple levels simultaneously.

The DermaQuest MelaQuest Cysteamine Serum contains micro-encapsulated cysteamine, an ingredient clinically studied to be more than one and a half times as effective as the standard prescription of four percent hydroquinone. The serum is enhanced with pure vitamin C, ginkgo biloba, and peptides, enabling visible results within seven days even on the most stubborn discolorations.

Active ingredients

Cysteamine HCl (4%, micro-encapsulated): A natural cell component and metabolite of L-cysteine that inhibits melanin production on multiple levels. Cysteamine acts both as an antioxidant and a tyrosinase inhibitor, and is the only non-prescription ingredient clinically compared to hydroquinone. The micro-encapsulation ensures steady release and better skin tolerance.

Vitamin C (Ascorbic Acid): Pure L-ascorbic acid in a stabilized formula. Works synergistically with cysteamine to further inhibit melanin production, protects the skin from free radicals, and stimulates collagen production for firmer skin structure.

Acetyl Glycyl Beta-Alanine: A peptide that supports skin structure during pigment correction. Helps maintain skin quality and contributes to smoother, more youthful skin.

Ginkgo Biloba Leaf Extract: A powerful plant-based antioxidant that soothes inflammation and protects the skin from environmental damage. Reduces the chance of irritation during the use of active ingredients like cysteamine.

Cyclodextrin: A natural sugar derivative that micro-encapsulates cysteamine. This allows the active ingredient to be steadily released to the skin, enhancing both effectiveness and wearing comfort.

Phytic Acid: A mild antioxidant and exfoliant derived from grains and legumes. Helps loosen dead skin cells and supports the penetration of the other active ingredients.
