The Skin Type Bible
THE SKIN TYPE BIBLE
The complete guide to understanding your skin.
Most people don't actually know their skin type. They know what their skin does — gets oily, feels tight, breaks out — but they don't know why. And without the why, every product choice is a guess.
This guide ends the guessing.
HOW TO ACTUALLY DETERMINE YOUR SKIN TYPE
Not from a quiz. From observation.
The bare-face test: Cleanse your face with a gentle cleanser. Pat dry. Apply nothing. Wait 60 minutes. Then observe.
If your skin feels tight, looks dull, and may have flaky patches: Dry skin.
If your skin looks shiny all over and feels slick: Oily skin.
If your T-zone (forehead, nose, chin) is shiny but your cheeks feel normal or dry: Combination skin.
If your skin looks balanced, feels comfortable, and has no significant shine or tightness: Normal skin.
If your skin looks red, feels reactive, stings, or itches: Sensitive skin (which can occur alongside any of the above types).
DRY SKIN
What's happening
Dry skin produces less sebum (natural oil) than other skin types. The skin barrier is often compromised, allowing moisture to escape and irritants to enter. This is a physiological characteristic — not a temporary condition.
What it needs
Hydration (water) and occlusion (sealing that water in). Humectants like hyaluronic acid draw moisture in. Emollients like ceramides and fatty acids smooth and soften. Occlusives like shea butter and squalane seal everything in.
What to avoid
Harsh cleansers that strip the skin. Alcohol-heavy products. Over-exfoliation. Hot water. Skipping moisturiser.
The dry skin routine
Gentle cream or oil cleanser → hydrating toner or essence → hyaluronic acid serum (on damp skin) → rich moisturiser with ceramides → SPF (morning). Evening: add a facial oil over moisturiser for extra occlusion.
OILY SKIN
What's happening
Oily skin produces excess sebum. This is largely genetic and hormonal. Sebum itself is not the enemy — it protects the skin. Excess sebum leads to shine, enlarged pores, and congestion.
What it needs
Gentle cleansing (not stripping — stripping triggers more oil production). Niacinamide to regulate sebum. Lightweight, non-comedogenic hydration. Regular, gentle exfoliation to prevent congestion.
What to avoid
Skipping moisturiser (dehydrated oily skin produces more oil to compensate). Heavy, occlusive creams. Over-cleansing. Harsh physical scrubs.
The oily skin routine
Gentle foaming or gel cleanser → niacinamide serum → lightweight gel moisturiser → SPF (morning). Evening: add a BHA (salicylic acid) 2–3x weekly for congestion.
COMBINATION SKIN
What's happening
Different zones of the face behave differently. The T-zone (forehead, nose, chin) has more sebaceous glands and produces more oil. The cheeks may be normal, dry, or even sensitive.
What it needs
Zone-specific treatment where possible. Lightweight products that don't overload the T-zone but don't under-hydrate the cheeks.
What to avoid
Treating the whole face as oily (dries out the cheeks). Treating the whole face as dry (congests the T-zone). One-size-fits-all heavy products.
The combination skin routine
Gentle cleanser → lightweight hydrating serum → gel-cream moisturiser → SPF (morning). Apply niacinamide to T-zone. Apply richer moisturiser to dry areas if needed.
SENSITIVE SKIN
What's happening
Sensitive skin has a compromised or reactive skin barrier. It responds to triggers — ingredients, temperature, stress, environment — with redness, stinging, itching, or flushing. Sensitivity is not a skin type in itself but a characteristic that can accompany any skin type.
What it needs
Barrier repair above all else. Minimal ingredients. Fragrance-free products. Gentle, consistent routine. Patch testing before introducing anything new.
What to avoid
Fragrance. Essential oils. High-concentration actives without building tolerance. Multiple new products at once. Anything that causes stinging or redness.
The sensitive skin routine
Fragrance-free gentle cleanser → barrier-repair moisturiser with ceramides → mineral SPF (morning). Introduce one active at a time, starting at the lowest concentration, 2x weekly.
AGEING SKIN
What's happening
Collagen production slows from the mid-20s. Cell turnover slows. The skin barrier becomes less efficient. Cumulative UV damage becomes visible. These are normal physiological processes — not failures.
What it needs
Retinoids (the gold standard). Vitamin C for antioxidant protection and brightening. Peptides for collagen support. SPF every single day — this is the most effective anti-ageing step available. Rich hydration.
What to avoid
Skipping SPF. Expecting overnight results from any product. Aggressive treatments that compromise the barrier.
The ageing skin routine
Gentle cleanser → vitamin C serum (morning) → peptide moisturiser → SPF. Evening: retinol 3x weekly (building to nightly) → rich moisturiser.
HYPERPIGMENTATION-PRONE SKIN
What's happening
Hyperpigmentation occurs when melanocytes produce excess melanin in response to inflammation, UV exposure, or hormonal changes. Post-inflammatory hyperpigmentation (PIH) follows breakouts or skin trauma. Melasma is hormonally driven. Sun spots are UV-driven.
What it needs
SPF every day without exception — UV exposure darkens existing pigmentation and creates new spots. Vitamin C to inhibit melanin production. AHAs to accelerate cell turnover and fade existing pigmentation. Niacinamide to reduce melanin transfer.
What to avoid
Sun exposure without SPF. Picking at breakouts (creates PIH). Expecting fast results — pigmentation takes months to fade.
