Every brightener makes the spot lighter. This one closes the gap.An age spot is not dark — it is darker than the skin beside it, and that gap is the only reason you can see it. Blanket brighteners lighten both, so the gap survives.Age spots hold two pigments: melanin, which most actives address, and lipofuscin, the yellow-brown pigment of accumulated cellular wear, which most ignore entirely. Delentigo™ was built around both, and built to be selective — garden-cress sulforaphane and soy genistein sit in separate vector liposomes, drawn to the elevated oxidative signalling inside the spot rather than acting on every cell they touch.In an eight-week placebo-controlled study on 12 women aged 40 to 77, applied twice daily to hand age spots — the most UV-damaged, stubborn pigmentation on the body — the pigment reading in treated spots fell 26%, while the normally pigmented skin around them moved 16.5%. The visible contrast between the two closed by roughly half. At four weeks in the same programme, the melanin index of treated spots was down 6.2% against placebo while normally pigmented skin was unchanged.It is here at 4%, the exact concentration those studies used, alongside MossCellTec™ No. 1 at 2%. Azeloglicina® sits in the base at 2% — below the level its own studies used, so we make no claim for it. Vitamin C ester, kojic acid and arbutin are base conditioners: named on the label, claimed nowhere.Why it cannot be dosed any higher. Delentigo™ carries soy isoflavones — the genistein that does part of the work. At 4%, that puts genistein at 0.0056% in the finished serum. The EU cosmetic safety ceiling for isoflavones is 0.007%. We are at eighty per cent of the legal limit, which is the real reason this serum is at 4% and not 6%.Applied in the morning, under sunscreen. The research is Mibelle Biochemistry's own, into these ingredients rather than into this finished serum.Contains soy isoflavones. Contains 0.34% alcohol. Patch test 48 hours before first use. Use sunscreen when exposed to sunlight. Results refer to the appearance of skin and vary between individuals.
