Short explainers on how skin works in general — not about your skin in particular. Each ends with a question to bring to your dermatologist.

Your skin, layer by layer

Skin is not one flat surface — it is layers, working together, all over the body. The epidermis is the thin outer layer you see and touch. It helps hold moisture in and keep everyday irritants out, and it is always renewing itself as new cells move up and old cells shed. The dermis is the thicker middle layer underneath — it holds the structures skin works with, including hair follicles and oil and sweat glands, and gives skin its strength and spring. The hypodermis is the deeper layer below the dermis, made largely of fat and connective tissue — it cushions, insulates, and anchors skin to what is underneath. What you see and feel — a breakout, dryness, a change in texture — is showing at the top layer, the epidermis.

Question to bring: “Which layer are we talking about for me?”

Learning the layers helps you describe what you notice. It does not let anyone — including this roadmap — work out what is happening in your layers. Only your dermatologist can assess your skin, in person.

The outer layer, simply

This layer sits mainly in the stratum corneum, the outermost layer of the epidermis. Think of it as bricks and mortar: the skin cells are the bricks, and the fats between them — ceramides, cholesterol and free fatty acids — are the mortar. Together they hold moisture in and keep everyday irritants out. When this layer is working well, skin holds its moisture; when it is not, water escapes more easily — that water loss is called transepidermal water loss, or TEWL. Gentle care helps this layer, and moisturising while skin is still damp after washing helps hold moisture in.

Question to bring: “How is my skin’s outer layer doing?”

Melanin, simply

Melanin is the pigment that gives skin its colour, and it is made in cells called melanocytes. There are two forms: eumelanin, which is dark brown or black, and pheomelanin, which is red or yellow. Melanin is packaged into tiny parcels called melanosomes, carried along the melanocyte’s arms, and passed to the neighbouring skin cells, where the melanosomes sit above the cell’s centre. How much of each form a person makes, and how it is packaged, is part of what makes every person’s skin different — variation is biology, not a ranking.

Question to bring: “What should I know about melanin and my skin?”

Safety line, printed with every suggestion: food is food — it is never presented here as a treatment, and eating a food is never promised to change your skin. Tell your dermatologist or doctor about allergies and about any big change to how you eat, and ask before using an herb regularly if you take medication, are pregnant or are nursing — some herbs and medicines do not mix.

Why minerals + vitamins are essential

The body cannot make most vitamins, and it cannot make minerals at all — they have to arrive, day after day, in food and drink. Minerals begin in soil and water, plants take them up as they grow, and fruits, vegetables and herbs are how they reach us.

Every line is general education about what a nutrient does in the body. No line says a food or nutrient will improve a reader’s skin, clear a breakout, or stand in for care, and no amounts, doses or supplement advice are given. If you wonder about your own levels, ask your doctor or dermatologist.

• Why prep matters: a short appointment counts when you arrive prepared.
• Why simple comes first: a routine you can keep beats a complicated one.
• Why tracking helps: your notes turn “how has it been?” into something your dermatologist can use.

A. Your history, on one page

• When you first noticed what you want to discuss, and how it has changed
• What you have already tried, and for how long each time
• Family skin history, if you know it — written as facts, not worries
• Allergies you already know about, listed plainly

B. Your photo log

• Same light, same angle, once a week — for your dermatologist, kept privately on your phone, not uploaded to us
• Cover every area you noted, face and body — use the body map to remember hard-to-see spots like your back
• Dates on each photo, so change over time is easy to show

C. Your product list

D. Your questions — pick your top 5

• Understanding: “Can you explain that in plain words?” / “What should I watch for?”
• Routine: “Does my current routine fit alongside this?” / “What order should things go in?”
• Next steps: “When should I come back?” / “What would make you want to see me sooner?”

Phase 1 — Start Simple (Weeks 1–2)

Gentle cleanse and moisturise, morning and evening, nothing new added. Raw African Soap for cleansing and Unrefined Shea Butter for moisturising are the Salus Moda starting pair named here — presented as the simple-care option, with no outcome promised. Goal of the phase: a routine you can actually keep.

Phase 2 — Find Your Rhythm (Weeks 3–4)

Same basics, steadier timing. Baby Shea is named here as the travel / on-the-go size of the same moisturising step. Review your tracker weekly and note what made days feel different — weather, sleep, new products, clothing + friction on body areas — as observations to discuss, not conclusions. Care stays whole-body aware: note responses anywhere, not only on the face.

Phase 3 — Make It Yours (Week 5 onward)

One change at a time, at least a week apart, logged in the tracker. Herbalist food suggestions from the map can join here too — as foods enjoyed at meals, logged in the tracker, never as a skin treatment.

Stop-and-ask rule, printed in every phase: if anything new does not feel right, stop using it and ask a professional. No roadmap phase ever tells you to push through discomfort. If your dermatologist’s plan says something different, their plan replaces the phase — always.

Your tracker

Two minutes a day. The tracker records what happened — it never judges it.

• Cleansed AM / PM · Moisturised AM / PM · Followed the visit plan today: yes / partly
• Anything new used today (product or first use)
• How skin felt today, in your own words — comfortable / tight / unsettled feeling
• Notes: weather, sleep, travel, stress — context, not causes
• Where breakouts appeared today — any area, face or whole body, marked on the front + back body map — noted, never scored
• How the surface (epidermis) felt there, in your own words — description for the dermatologist, not a diagnosis
• Suggested fruits, vegetables or herbs enjoyed today — one line, as food enjoyed, not as a dose taken

Weekly review (5 minutes, Sunday): Did I keep the routine most days? What one thing changed this week? What is my one question for next time? Those three answers become page 1 of the next visit’s prep.
