How to build a basic skincare routine
Four steps cover most skin: cleanse, treat, moisturise, protect. Here is what each one is actually for, and where to spend if you're starting from nothing.
Start with fewer products, not more
A basic routine is a cleanser, a moisturiser and a sunscreen used daily, with a serum added once those three are established. Adding several active ingredients at once makes it impossible to tell what is working or what is causing irritation. On Amazon UK, cleansers in this dataset range from around £6 to £35, and there is no reliable link between price and how well a gentle cleanser performs its basic job of removing dirt and makeup without stripping the skin.
Cleanser: the step people overdo
A cleanser's job is to remove what sits on top of skin — oil, sunscreen, makeup, pollution — without disrupting what is underneath. Foaming cleansers can be effective but are also the easiest to overuse into dryness; cream and gel formulas are usually gentler for daily use. Twice a day is standard; more than that is rarely necessary for most skin types and can cause the very dryness or breakouts people are trying to fix.
Moisturiser: matching texture to skin type, not marketing
Moisturisers in this category span roughly £6 to £22, and the difference between a £6 and a £20 option is far more often texture and finish than a meaningful gap in effectiveness. Gel and lotion textures suit oily and combination skin; richer creams suit dry skin, particularly in winter. The main job of a moisturiser is to reduce water loss through the skin's outer layer — an unglamorous mechanism, but the one that actually matters.
Serum: optional, and only once the basics are settled
A serum concentrates one or two active ingredients — commonly vitamin C, niacinamide or hyaluronic acid — into a lightweight formula applied before moisturiser. Serums on Amazon UK in this dataset range from around £5.50 to £26. They are worth adding once cleansing and moisturising are consistent, not before, because a new active is harder to evaluate against a routine that is also still changing.
Sunscreen: the step with the clearest evidence behind it
Daily sunscreen is the single step with the most consistent evidence for protecting skin's long-term appearance and health, yet it's frequently the one people skip. Formulas in this dataset range from around £6 to £32, and SPF30 or SPF50 applied every morning matters more than brand. Mineral formulas (zinc oxide, titanium dioxide) suit sensitive or reactive skin; chemical filters tend to sit more invisibly under makeup.
A realistic order of operations
Morning: cleanser, serum (if used), moisturiser, sunscreen. Evening: cleanser, serum (if used), moisturiser. Introduce one new product at a time and give it two to four weeks before judging it — skin takes time to show whether something is helping, doing nothing, or causing a reaction, and judging too early is the most common reason people abandon products that would have worked.

Frequently asked questions
- Do I need all four steps every day?
- Cleanser, moisturiser and sunscreen daily cover most people's needs. A serum is a genuine optional extra rather than a required step — plenty of good routines skip it entirely.
- Is a more expensive moisturiser always better?
- Not reliably. In this category, price differences of £15 or more are often about texture, packaging and brand rather than a proven gap in how well the product moisturises.
- How long before I know if a product is working?
- Two to four weeks for most skincare, and longer for anything addressing texture or tone over time. Judging a product after a few days rarely tells you anything reliable.
- Can I use a serum without a moisturiser?
- You can, but most serums are formulated to work alongside a moisturiser that seals in the actives and prevents water loss, so skipping it usually means losing some of the benefit.
