How to build a skincare routine — and how to keep it.

Most people come to skincare through one of two paths: a friend's recommendation, or an algorithm. Both tend to result in the same outcome — a shelf of products that don't quite work together, applied in a sequence that was never really decided.

Building a routine that actually serves your skin is simpler than it sounds. The principle is not complicated. The execution is where most routines fail.

The problem with most routines

A typical skincare routine accumulates, not by design, but by addition. A new serum here, a trending active there, an impulse purchase that seemed evidence-based at the time. The result is a routine built around individual products rather than around the skin's actual needs.

Complex routines also create complex problems. Multiple actives in a single routine can compete for the same receptor sites, cause pH conflicts, or simply overwhelm the barrier. They are harder to troubleshoot when something goes wrong. And they are harder to sustain — the most common reason a routine fails is that it takes too long.

Start with the three functions

A complete skincare routine does three things.

Cleanse. Remove the oxidised sebum, sunscreen, and environmental debris that accumulate through the day. This is the most important step. Nothing applied afterward works on skin that has not been properly prepared.

Treat. Apply a single evidence-based active to address the skin's specific needs. Not three or four — one. The evidence for most active ingredients at useful concentrations is strong. The evidence for stacking many actives simultaneously is thin.

Hydrate. Seal the treatment step and support the barrier. A well-formulated moisturiser — with squalane, ceramides, or shea butter — completes the routine. It reduces transepidermal water loss and provides the barrier with the lipids it needs to function.

These three steps address the foundational requirements of the skin. Everything else is supplementary.

The one-variable rule

When building a new routine — or introducing a new product to an existing one — add one thing at a time. Use it for six to eight weeks before evaluating it and before adding anything else.

Skin does not respond quickly to most ingredients. The timeline for meaningful change is weeks and months, not days. Adding multiple products simultaneously makes it impossible to determine which one is working, which one is causing a reaction, and which one is doing nothing at all.

The one-variable rule is not exciting. It is the only reliable method.

On order

Apply products thinnest to thickest. A lightweight serum second, a moisturiser last. Oil-based cleansers go on dry skin; everything else on damp or recently cleansed skin. Leave brief intervals between steps if layering actives — most actives do not require extended wait times, but they should not be applied simultaneously to the same area of the face.

Sunscreen is not a step

Sunscreen belongs before everything else in the morning, under makeup. It is not part of a skincare routine — it is a prerequisite. Daily broad-spectrum SPF 30 or higher prevents more visible skin ageing than any serum or moisturiser on the market. It is also non-negotiable.

When to add more

After six to eight weeks on a three-step baseline — if the skin is balanced, not reactive, and the barrier is intact — there may be a case for adding a specific active. Retinoids for cell turnover. Exfoliating acids for texture. A targeted treatment for specific concerns.

But the baseline comes first. A stable, well-functioning barrier is the prerequisite for any active to work. Adding retinol to compromised skin does not accelerate results; it causes inflammation.

The three-step routine as a default

The Lux & Glo ritual is designed as a sustainable default: an oil cleanser that does not disrupt the barrier, a niacinamide serum at a concentration with clinical evidence behind it, and a moisturiser that seals and supports. Three steps. Ten minutes. Done consistently.

It is not designed to replace a dermatologist's recommendation for specific clinical concerns. It is designed to be the routine you actually do, every day, for as long as you use it.

That is the point.
