How to Build a Skincare Routine

Skincare can seem endlessly complicated — a thousand products, conflicting advice, a viral trend every week. But a good routine is actually quite simple. Here's step by step how to build one that really works, in the right order, without wasting money.

In short: A basic routine has four steps in the morning (cleanse, optional serum, moisturizer, sunscreen) and three-to-four at night (cleanse, optional active serum, moisturizer). Start simple, introduce one new product at a time, and build from there. Sunscreen is the most important step — full stop.

The golden rule: thin to thick

The order of products comes down to consistency: you go from thinnest (watery) to thickest (creamy). Thin products penetrate the skin; thicker ones sit on top and "lock in." Use them in the wrong order and a thick cream can block the serum underneath from getting in.

The core principle: start with the thinnest product and work toward the thickest. Sunscreen is always the last morning step.

Morning routine (protect)

In the morning, skincare is about protecting your skin through the day:

Cleanse AM

A gentle cleanser, or just rinse with water if your skin is dry. You don't need a strong cleanser in the morning.

Serum — e.g. vitamin C AM

Optional. An antioxidant like vitamin C protects against environmental damage and adds glow. Layer under sunscreen.

Moisturizer AM

Holds moisture and strengthens the barrier. Choose a light gel for oily skin, a richer cream for dry.

Sunscreen — the most important step AM

SPF 30–50, every day, all year. Sun causes most visible skin aging. Without this, the rest is almost wasted.

Evening routine (repair)

At night it's about repairing and renewing while you sleep:

Cleanse PM

Remove sunscreen, makeup and grime. If you wear a lot of sunscreen/makeup, double cleanse (oil first, then regular cleanser).

Active serum — e.g. retinol or acid PM

Optional, but this is where the "anti-aging" work happens. Retinol and acids are used at night. Not the same night — alternate.

Moisturizer PM

Locks in and helps skin repair overnight. Can be richer than your morning cream.

The most common mistake: doing too much, too fast. Starting five new active products at once is the surest path to irritated, damaged skin. Introduce one new product at a time, give it 2–4 weeks, and see how your skin reacts before adding more.

What do you actually need? (Minimum)

If you're only going to have three products, make them these:

A gentle cleanser — to start with clean skin
A moisturizer — for barrier and hydration
A sunscreen — for protection (the single product with the most documented anti-aging effect)

Everything else — serums, acids, retinol, essences — is an add-on you build once the foundation is solid. Don't let marketing convince you that you need ten steps. Most people with great skin have a simple, consistent routine.

How to tailor it to your skin

The "best" routine doesn't exist — it depends on your skin type, age, goals and what you tolerate. Oily skin wants light products and maybe BHA; dry skin wants richer creams and hyaluronic acid; mature skin benefits more from retinol. If you're unsure, that's exactly why we built Skinatlas:
