The MelaQuest Cysteamine Serum from DermaQuest is a serum for stubborn pigmentation, such as deep-set dark spots. It works without hydroquinone and supports a visibly more even, brighter skin tone. Cysteamine and Vitamin C together visibly reduce pigment spots. Ginkgo Biloba Extract protects the skin from outside influences, while Phytic Acid and Glycerin provide gentle exfoliation and intensive hydration. As a result, skin feels calmer, smoother and more refined.
MelaQuest Cysteamine Serum suits normal, dry, combination, oily and sensitive skin, especially with stubborn pigment spots or an uneven skin tone. Using a Cysteamine serum for the first time? Build up the frequency gradually. You can also browse Olivida's wider pigmentation collection.
Cleanse your skin first with your own cleanser. Then apply a thin layer of MelaQuest Cysteamine Serum to your face, neck and décolleté. Follow with the MelaQuest Cream and always wear a daily SPF to help prevent new pigmentation. Use this product in the morning and/or evening, twice a day.
MelaQuest Cysteamine Serum is one of seven MelaQuest products Olivida carries from DermaQuest, including two serums and two day creams, each with a different formula. Alongside this serum, Olivida also sells the Advanced MelaQuest Serum, with Arbutin and Bakuchiol instead of Cysteamine. Prefer a cream? The MelaQuest Cream with Cysteamine contains a comparable 3% cysteamine complex, alongside Morus Alba extract and Bakuchiol.
