Routine
Quick answer: the evidence-backed summer minimum is four steps — gentle cleanse, targeted serum, light moisturiser, broad-spectrum SPF — in the morning, and cleanse + treat + moisturise at night. Everything beyond that is optional; most 10-step routines just multiply the chances of irritation in the heat.
Why less works better in summer
Heat increases oil production and product breakdown; sweat moves layered products around; and stacking actives raises irritation risk exactly when UV exposure peaks. Clinical reviews of skincare routines consistently support consistency over complexity — a simple routine done daily beats an elaborate one done sporadically.
The morning routine (3–4 minutes)
- Cleanse — a gentle gel; overnight oil rinses off without a deep clean. See Cetaphil and Avène for reliably gentle options.
- Serum (optional but valuable) — an antioxidant like vitamin C under SPF is summer's best-supported pairing.
- Light moisturiser — gel-cream in heat; even oily skin should not skip this (dehydrated oily skin overproduces oil).
- SPF 30–50 — the non-negotiable step; browse the SPF collection.
The evening routine
- Cleanse properly — 60 seconds to remove the day's SPF and sweat (this is the step summer skin most often misses).
- Treat — your one targeted active: retinol for ageing (night-only), salicylic acid for blemishes, or a brightening serum for tone.
- Moisturise — seal it in.

Frequently asked questions
What is the correct order to apply skincare in summer?
Thinnest to thickest: cleanse, serum, moisturiser, then SPF as the final morning step. At night: cleanse, treatment, moisturiser.
Do I need a heavy moisturiser if my skin is oily?
No — but do not skip moisturiser entirely. A light gel-cream keeps oily skin hydrated; dehydrated oily skin typically produces even more oil.
Can I skip moisturiser and just use SPF?
If your SPF is hydrating and your skin is happy, a separate moisturiser is sometimes optional in summer — but most skin does better with a light hydrating layer underneath.
How many steps should my summer routine have?
Four in the morning (cleanse, optional serum, light moisturiser, SPF) and three at night. Consistency beats complexity.
Is double cleansing necessary in hot weather?
Only in the evening, and only if you wear SPF plus makeup or heavy sweat. One thorough 60-second cleanse is an acceptable alternative.
