easydew Dark Spot Ampoule

Ingredient analysis and how the ad lines read

What is this product?

easydew's 기미잡티앰플 does the thing almost no brightening product does: it prints the amount on the panel, niacinamide at 5 percent, the top of the range Korea allows for a notified whitening ingredient, with alpha-arbutin, 3-O-ethyl ascorbic acid, tranexamic acid and glutathione stacked right beneath it at 15 through 18 of 86. The EGF in the brand name is disclosed at 1.5ppm and sits 14th, so it is the least of what this 12ml ampoule does. Avoid it if fragrance is a problem: five named essential oils (marjoram, bergamot, chamomile, Mexican juniper, grapefruit peel) start at 20, limonene and linalool are declared at the end, and ethanol plus t-butyl alcohol sit at 80 and 81.

What makes it different?

The disclosed 5 percent is the whole argument. Korean brands routinely name niacinamide and almost never print how much, so a number on the statutory panel converts a marketing word into a checkable fact, and 5 percent is where the published melanosome-transfer work actually sits. Depth beyond that is unverifiable, since everything from alpha-arbutin down carries no amount at all. The formula also runs against itself in one respect worth weighing: it treats pigment while carrying five citrus and herb essential oils and two alcohols, and inflammation is what drives the marks. easydew publishes no pH and no clinical result for it. The container is at least known: a syringe-form ampoule in a sterile wrap, opened by cap and pushed out by plunger, which is worth knowing for a formula built on five ascorbate derivatives even though no stability result for it is published.

Ingredients with no mark are ones we found nothing notable about, and when marks overlap on one ingredient we show the caution first.

We could not place these in the list above: Origanum Majorana Leaf Oil, Citrus Aurantium Bergamia (Bergamot) Fruit Oil, Chamomilla Recutita (Matricaria) Flower Oil, Juniperus Mexicana Oil, Citrus Grandis (Grapefruit) Peel Oil, Caprylic/Capric Triglyceride, Helianthus Annuus (Sunflower) Seed Oil
