Back home
Your skin doesn't behave the same in July as it does in December. As humidity, temperature and UV shift, the same routine can feel too heavy in summer and too light in winter. Small seasonal tweaks make more difference than a whole new shelf of products.
Summer — light, protective, cooling
Heat and humidity push oil production up, sweat away sunscreen, and increase UV exposure. Aim for lighter textures, more frequent SPF reapplication and soft sebum control.
- Swap rich creams for gel-creams or watery emulsions.
- Use SPF 50 daily and reapply every 2 hours outdoors.
- Add niacinamide or a gentle BHA 2–3 times a week to keep pores clear.
- Keep hydrating toners and mists in the fridge for a cooling refresh.
- Cleanse morning and evening — sunscreen and sweat both need removing.
- Ease off heavy actives on very hot days if your skin feels sensitised.
Winter — rich, repairing, barrier-first
Cold air outside and dry indoor heating strip moisture from the skin. Barrier damage, tightness and flakiness peak here. Prioritise layered hydration and quiet repair.
- Switch to cream cleansers and low-pH formulas — no foaming sulphates.
- Layer humectants (hyaluronic acid, glycerin, panthenol, polyglutamic acid) on damp skin.
- Choose richer moisturisers with ceramides and squalane.
- Consider a sleeping mask or thin balm 'slug' 2–3 nights a week.
- Reduce active exfoliation — one AHA/BHA night a week is often enough.
- Keep wearing SPF — UVA passes through cloud, and snow reflects UV.
In-between: autumn and spring
The transition seasons are when skin often reacts — barriers get confused by changing humidity. Simplify. Focus on low-irritation cleansing, one hydrating serum, one moisturiser and daily SPF. Add or remove one active at a time as the weather settles.
