DermaQuest MelaQuest Cysteamine Serum 29,6ml

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.

Benefits

• Reduces stubborn pigment spots, melasma, and post-inflammatory pigmentation
• Clinically studied as more effective than prescription hydroquinone
• Delivers visible results after just seven days of consistent use
• Protects the skin against oxidative stress and new pigment formation
• Suitable for those who previously had insufficient results with other brighteners

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.

How to use

2. Optionally apply a toner to the face, neck, and décolleté
3. Apply a thin layer of serum over the pigmented areas, avoiding the immediate eye contour
4. Use the serum twice daily, morning and evening, and follow with the MelaQuest Cream
5. Always protect the skin during the day with a broad-spectrum sunscreen with at least SPF 30 to maintain results and prevent new pigmentation formation

Suitable for

• Stubborn melasma that does not respond to milder brighteners

Frequently asked questions

When will I see the first results?

Initial improvements in radiance and skin texture are often noticeable after seven days. For visible reduction of pigmentation spots, consistent use for six weeks is usually required, and optimal results are achieved after eight to sixteen weeks of consistent use combined with daily sun protection.

Does the serum have a specific scent?

Cysteamine naturally has a characteristic odor that cannot be completely masked. The formula is developed so that the scent is largely softened by other ingredients and quickly dissipates after application to the skin.

Is this serum suitable for sensitive skin?

Due to the high concentration of cysteamine, this serum is generally not recommended for very sensitive skin. For a milder approach, the Advanced MelaQuest Serum without cysteamine is a more suitable alternative. When in doubt, always perform a patch test on the neck area first.

Can I use this serum during pregnancy or breastfeeding?

Cysteamine is not recommended during pregnancy and breastfeeding. Always consult your doctor or midwife before using this serum during this period.

Can I combine this serum with retinol?

Preferably do not combine cysteamine and retinol in the same routine to avoid irritation. For example, use retinol on separate evenings and give the skin enough time to tolerate both actives well.
