REJURAN Derma Healer Moisture Treatment Ampoule

What is this product?

Rejuran's Derma Healer Moisture Treatment Ampoule, 30ml, is a sensible pick for reactive skin that wants soothing botanicals plus a real barrier lipid tail, and a poor one for anyone who reacts to citrus, because grapefruit peel oil is printed fifteenth of its 28 ingredients. Calendula, aloe vera juice, cucumber and oat kernel extracts run through the top twelve, and ceramide NP, cholesterol, palmitic acid and oleic acid close the list as a complete barrier lipid set. Rejuran publishes no amount for any of it, no pH, and no test behind the strong calming line on the box.

What makes it different?

What separates it from an ordinary calming ampoule is the tail rather than the top. Most soothing serums stop at extracts; this one closes with ceramide NP, cholesterol, palmitic acid and oleic acid, which is the ceramide plus cholesterol plus fatty acid combination the barrier repair literature is actually built on, not a lone ceramide token. The cost is a real one to name: grapefruit peel oil sits fifteenth of 28, and expressed citrus peel oils carry photosensitising furocoumarins unless the supplier has removed them, which Rejuran does not state either way. There is no declared fragrance and no denatured alcohol anywhere in the 28. The other limit is quantitative: nothing on the label or the pages read carries a percentage, so the barrier set can be named but not sized.
