Dermafirm Bio Correction Ampoule Cera-Drop M4

What is this product?

Dermafirm's Bio Correction Ampoule Cera-Drop M4 is a hydration ampoule first and a ceramide product second, despite the name: it carries six different hyaluronic acid forms plus glyceryl glucoside and galactoarabinan, but only one ceramide, sitting in the back half of 45 ingredients with no amount given. It also carries the full centella set, asiaticoside, madecassoside, madecassic acid and asiatic acid, which is more complete than most soothing serums manage.

What makes it different?

Six hyaluronic acid forms across different molecular weights is a genuine spread rather than one ingredient listed twice. The centella panel is unusually complete: rather than a single 병풀추출물 entry, all four of the isolated actives are printed separately alongside the extract. No 향료 entry and no drying alcohol appear among the 45 ingredients. Two free fatty acids, oleic and caprylic, are in the list, which is worth knowing for anyone who tracks fungal acne or reacts to oleic acid.
