Building a Skincare Routine
Also known as skincare basics, routine building
Four products do 90% of the work. Everything beyond that is refinement, and most of it is marketing.
A complete effective routine: $40–80 total, lasting 2–3 months.
How it works
An effective routine does three things: cleanses without stripping the acid mantle, supports the barrier with humectants and lipids, protects against UV, and applies one or two evidence-backed actives. Adding more products increases irritation risk and makes it impossible to identify what is helping.
How it's used
Morning: gentle cleanser, moisturiser, broad-spectrum SPF 30+. Evening: gentle cleanser, an active (retinoid most nights), moisturiser. Introduce one new product at a time and give it six weeks before judging. If the skin is irritated, remove products rather than adding a soothing one.
Trade-offs
In favour
- Cheap — a complete effective routine costs under $60
- Simple enough to actually maintain
- Easy to diagnose problems when the routine is short
- Covers the great majority of achievable benefit
Against
- Requires patience and consistency
- Boring compared with elaborate multi-step routines
- Results are gradual
Risks and side effects
- Over-exfoliation and barrier damage from stacking too many actives
- Fragrance and essential oils are common irritants
- Skipping SPF while using a retinoid actively worsens pigmentation
How good is the evidence?
The individual components — cleansing, moisturising, photoprotection, retinoids — each have strong evidence. Elaborate multi-step routines do not.
