For skin professionals · Clinical education
Evidence-based skincare, without the noise.
A practical clinical guide to choosing, sequencing and simplifying skincare.
Created by Dr Mica Engel, Medical Doctor and founder of D.E.N. Skincare.
What's inside
Six parts, one way of thinking
It won't tell you what to prescribe. It will help you decide.
Clinical reasoning
How to approach skincare as treatment rather than product selection.
Skin pathways
Barrier dysfunction, inflammation, pigment dysregulation, sebum imbalance and collagen decline.
Six common presentations
Acne, rosacea and sensitive skin, melasma, ageing, menopause and male skin.
Ingredient prescribing
What different actives are designed to do, where they fit and when caution is required.
Practical prescribing
How to build routines patients will actually use, when to escalate and when to stop.
Clinical tools
Reference guides, routine checklists, escalation guidance and patient communication principles.
Clinical tools
Made to sit beside your desk
This isn't only theory. The appendices are one-page tools you can print and use in clinic the same day.
Routine design checklist
Nine checks before any routine leaves the room, plus a one-page patient plan template.
Escalation and review guide
When to escalate, when to pause and when to step down, at a glance.
Patient communication
The principles, with wording for starting a routine, setting expectations and handling stinging.
