Product catalogue

The shape of a routine,
in one shelf.

Reference products by the role they play — not a store. Each card shows what the product is for, the active that does the work, how strong the evidence is, and a representative price band. Use it to recognise a routine; build your own at the desk.

Cleansers & exfoliants

What comes off, and how often.

Cleanser

Gentle gel cleanser

The morning and evening wash

A non-foaming gel that lifts oil and sunscreen without stripping the barrier. The default for almost every routine; a second cleanse at night removes SPF and makeup.

Active
Glycerin, mild surfactants

Cleanser

Fragrance-free cream cleanser

For dry or reactive skin

A creamy, low-foam cleanser for skin that feels tight after washing. Leaves more of the lipid layer intact than a gel; pair with a morning rinse-only on low-tolerance days.

Active
Ceramides, glycerin

Exfoliant

Salicylic acid cleanser

For congestion

A 2% BHA cleanser for blackheads and oil control that rinses off, so it is gentler than a leave-on. Use three nights a week; contact time matters less than consistency.

Exfoliant

Glycolic acid toner

The weekly resurfacer

A 5–7% glycolic toner for texture and dullness, one to three nights a week. Never on a retinoid night; stop if stinging or flushing appears. Not for reactive or pigmentation-prone skin.

Serums & actives

The leave-on steps that do the work.

RRetinoid

Adapalene 0.1% gel

The entry retinoid

The most studied over-the-counter retinoid for breakouts and texture. Start every third night, buffered under moisturiser; the cheapest, best-evidenced active in the cabinet.

Active
Adapalene 0.1%

Typical price

$12–22

●●●

RRetinoid

Retinal 0.05% serum

For tolerating skin

One step closer to prescription retinoic acid, for skin that has outgrown adapalene. Faster results, more irritation risk; build the barrier first and use every other night.

Active
Retinaldehyde 0.05–0.1%
Evidence
Supported

Typical price

$28–48

Mid-range

●●●

Antioxidant

Niacinamide 5–10% serum

For oil and tolerance

Reduces visible oiliness and supports the barrier at 4–5%. Stable, cheap, and plays well with every other active; the rare ingredient that earns a slot in almost any routine.

Antioxidant

Vitamin C 10–15% serum

The morning antioxidant

L-ascorbic acid around 15% for antioxidant and mild pigment support. Photodegrades fast; buy airless, keep dark, and pair with SPF. The evidence is real but modest.

Treatment

Hydrocolloid spot patch

For active spots

A flat patch that absorbs fluid from a headless spot overnight and stops you touching it. Cheap, low-risk, and genuinely effective for the spot you have today, not the routine you build.

Treatment

Panthenol / centella soothing serum

For reactive skin

A calming serum for skin that reacts to everything. Reduces the redness and stinging that retinoids and exfoliants cause; the buffer that makes stepping up possible.

Evidence

Typical price

$10–20

Treatment

Azelaic acid 10% serum/cream

For redness and marks

A 10–15% azelaic serum for post-acne marks, rosacea-like redness, and melasma. One of the few actives safe across skin tones for pigmentation; pair with daily SPF.

Moisturisers & protection

What holds the routine in place.

Moisturiser

Oil-free gel moisturizer

The morning hydrator

A gel-cream for normal-to-oily skin that hydrates without heaviness. Goes under SPF in the morning and under a retinoid at night; the routine's connective tissue.

Active
Glycerin, hyaluronic acid, niacinamide

Typical price

$10–18

●●●

Moisturiser

Rich night cream

For dry and mature skin

A heavier emollient cream for skin that needs oil, not just water. The final step that locks in a retinoid or active; reduce to a lighter one in humidity.

Active
Shea, squalane, ceramides
Evidence

Typical price

$28

Barrier repair

Ceramide barrier cream

The evening seal

A petrolatum- or ceramide-rich cream for the last step at night. Repairs a compromised barrier from retinoids, over-exfoliation, or cold; the cheapest effective thing you can do.

Sun protection

Fluid / hybrid SPF 40–50

Sun protection

Mineral SPF 30–50 face lotion
