The Skin Diary

At Maison 4, we value skincare that feels purposeful, corrective and grounded in genuine dermatological science. The Skin Diary reflects that approach beautifully, offering advanced skincare designed to support visible skin change with clarity, precision and respect for the skin barrier. Developed by leading experts in skin ageing, the brand is built around a refined, results-led philosophy that prioritises repair, protection and long-term skin health. 

Distinctive in its simplicity, The Skin Diary is not built around an extensive multi-step range, but around an elegant two-step protocol: one essential product in the morning and one at night. With Age Defence created as a complete single-step morning formula, and Night Repair Therapy positioned as a modern alternative to traditional retinol, the collection brings clinical credibility to a routine that feels streamlined, sophisticated and easy to maintain.
