Dermaquest
Advanced cysteamine pigmentation serum for stubborn dark spots, melasma and persistent uneven skin tone.
DermaQuest MelaQuest Cysteamine Serum is a high-performance brightening treatment developed for pigmentation that has proven difficult to manage with conventional brightening products alone.
The lightweight leave-on formula combines DermaQuest’s 4% Cysteamine Complex (NV Cysteamine 15) with 8% Ascorbic Acid, Phytic Acid, Acetyl Glycyl Beta-Alanine and Ginkgo Biloba Extract.
Its multi-pathway approach targets excess melanin production while providing antioxidant and tone-supporting activity, making it particularly relevant for stubborn pigmentation, including melasma and recurrent dark marks.
Unlike traditional short-contact cysteamine creams, DermaQuest currently formulates this product as a leave-on serum for twice-daily use.
Benefits:
4% Cysteamine Complex (NV Cysteamine 15)
The hero pigmentation technology in MelaQuest Cysteamine Serum.
Cysteamine is a naturally occurring aminothiol with strong antioxidant properties and established use in topical pigmentation management.
It helps interfere with pathways involved in excess melanin production, making it particularly relevant for stubborn hyperpigmentation and melasma.
DermaQuest describes the product as containing 4% Cysteamine Complex (NV Cysteamine 15).
The 4% refers to the brand's cysteamine complex as formulated and should not automatically be interpreted as 4% pure Cysteamine HCl.
Micro-Encapsulated Cysteamine Delivery System
The current INCI contains Cysteamine HCl, Cyclodextrin, Algin and Calcium Citrate.
These ingredients form part of DermaQuest's cysteamine delivery system, designed to stabilise and deliver cysteamine within the leave-on formula.
This differentiates it from traditional cysteamine products that may require short-contact application and rinsing.
8% Ascorbic Acid
Pure Vitamin C provides complementary antioxidant and pigmentation-supporting activity.
It helps neutralise free radicals associated with environmental and UV exposure while supporting a brighter, more even-looking complexion.
Vitamin C also provides complementary collagen-related age-support benefits.
Phytic Acid
A multifunctional antioxidant and pigmentation-supporting ingredient.
Phytic Acid helps reduce oxidative stress while supporting regulation of processes involved in melanin production.
It strengthens the pigmentation strategy without making the serum primarily an exfoliating treatment.
Acetyl Glycyl Beta-Alanine
A peptide-related brightening ingredient included within the current formula.
It provides complementary tone-evening support and forms part of DermaQuest's multi-pathway pigmentation approach.
Ginkgo Biloba Leaf Extract
A botanical antioxidant that helps protect skin against environmental oxidative stress.
It complements the Vitamin C and Phytic Acid components within the serum.
Glycerin
Provides humectant hydration and helps maintain skin comfort while using an intensive pigmentation treatment.
Full Ingredient List:
Water (Aqua), Propylene Glycol, Isopentyldiol, Ascorbic Acid, Ethoxydiglycol, Acetyl Glycyl Beta-Alanine, Aminomethyl Propanol, Polysorbate 20, PEG-8 Dimethicone, Ginkgo Biloba Leaf Extract, Glycerin, Sodium Metabisulfite, Sodium Citrate, Cysteamine HCl, Cyclodextrin, Algin, Calcium Citrate, Disodium EDTA, Phytic Acid, Caprylyl Glycol, Ethylhexylglycerin, Hexylene Glycol, Phenoxyethanol, Sodium Benzoate, Potassium Sorbate.
