Dermaquest MelaQuest Cysteamine Serum 26ml

Dermaquest’s MelaQuest Cysteamine Serum is an advanced brightening serum designed to help even out the look of stubborn discolouration, dark spots and uneven skin tone. It’s part of the MelaQuest range, created for more persistent pigmentation concerns, including melasma. The brand’s own description highlights micro-encapsulated cysteamine as the hero ingredient, paired with vitamin C and peptides to support a more unified, radiant-looking complexion.

According to Dermaquest, visible results can be seen in as little as 7 days, and the serum can be incorporated into hyperpigmentation routines alongside other homecare or in-clinic treatments. As part of the same product information, the routine suggestion is to apply a thin layer to cleansed and toned skin (face, neck and décolleté) twice daily, then follow with MelaQuest Cream. Dermaquest also notes that the formula may cause photosensitivity, so daily sun protection is recommended.

Notable ingredients include cysteamine HCl (listed in the formula), ascorbic acid (vitamin C), phytic acid and ginkgo biloba leaf extract, alongside supportive ingredients including cyclodextrin and algin.
