JAYJUN Intensive Brightening Sleeping Pack
Ingredient analysis and how the ad lines read
Read on 2026-09-13
What is this product?
An overnight leave-on sleeping pack in single-use 4ml pouches, built as a vitamin and flower-extract formula in a water and glycol base with visible beads suspended in it. Four vitamin C derivatives sit among the 46 declared entries alongside two tocopherol forms and a run of ten flower-bearing entries, with adenosine at 35 as the one notified functional active. The most important thing to know is the mismatch between name and registration: the product is called Intensive Brightening, but the statutory panel registers anti-wrinkle only, and the brand makes no brightening claim anywhere on its own page. The antioxidant claim rests on a test-tube assay, which the brand's own footnote states plainly as in-vitro, reporting about 13 percent radical scavenging; a separate 22 subject application test returned 148.5 percent on moisture but only about 2 percent on the translucency endpoint closest to the product's name. Two things to weigh: fragrance and two tar colourants are declared in a product worn overnight, and there is no lipid of any kind in the list, so dry skin will need a moisturiser over it. The brand discloses that the amount of beads varies between units.
What makes it different?
A vitamin and flower-extract overnight pack with visible beads whose quantity the brand admits varies by unit, carrying a brightening name against an anti-wrinkle registration and an antioxidant figure the brand itself labels as measured outside the body.
