Ingredient analysis and how the ad lines read

What is this product?

Rejuran's Healer Turnover Ampoule Dual Effect is a light brightening ampoule for uneven tone, worth skipping during pregnancy because arbutin is printed thirtieth of its 40 ingredients and arbutin releases hydroquinone on the skin. Its pigment-directed group is arbutin, bisabolol, licorice root and black mulberry fruit, with niacinamide eighth, and a hydrolyzed DNA entry sits high at position ten under a trade name. It is registered as a dual functional cosmetic for whitening and wrinkle care, with adenosine and niacinamide named as the notified actives. Rejuran publishes no amount for any of it, no molecular weight for the DNA material and no pH, and it sells in two listings, a 10ml double pack and a 30mL single.

What makes it different?

What sets it apart is a pigment-directed group assembled from four different mechanisms rather than one showcase active: arbutin as a tyrosinase substrate analogue, bisabolol and licorice root glabridin working on the same enzyme from other directions, black mulberry fruit as the botanical entry, and niacinamide at position eight interrupting melanosome transfer downstream. That is a coherent design, and it is also the reason to be careful with it, because arbutin hydrolyses to hydroquinone at the skin surface and is one of the entries pregnancy guidance singles out. The nucleic acid material is placed unusually high, at position ten under a trade name and again at eighteen on its own, though no amount or molecular weight is published for either. There is no declared fragrance, no essential oil and no denatured alcohol among the 40.
