How to Stop Dry Skin in Summer: Sun, Heat & Air-Con

Dry skin isn't just a winter problem. Plenty of people find their skin gets tight, flaky and irritated in summer too — and then assume they're doing something wrong. You're not. Sun, air-conditioning, chlorine, salt water and even sweat can all strip moisture and damage the skin barrier. Here's how to keep your skin hydrated and comfortable right through summer.

Yes, summer dries skin out too

It seems counter-intuitive when the air feels humid, but several summer factors quietly dehydrate skin: UV exposure damages the barrier and accelerates water loss; air-conditioning removes moisture from indoor air just like winter heating; chlorine and salt water strip natural oils; and frequent showering after sweating or swimming, often in hot water, washes away protective lipids. The result is the familiar tight, flaky, sometimes itchy skin — just with a summer cause.

7 tips to stop dry skin in summer

  1. Wear sunscreen every day. Broad-spectrum SPF 30+ is the single best thing you can do — it prevents the UV damage that weakens your barrier. Choose a moisturising, hydrating formula rather than a drying matte one.
  2. Don't over-wash. Rinsing off sweat, chlorine and sand is good, but keep showers short and lukewarm, and use a gentle, fragrance-free wash instead of stripping soap.
  3. Moisturise after every shower — still within 60 seconds, on damp skin. You may switch to a lighter lotion than your winter cream, but don't skip it.
  4. Counter the air-con. If you're in cooled offices or cars all day, keep a hydrating mist and a hand cream nearby, and consider a small humidifier at home.
  5. Add a hydrating serum. Lightweight hyaluronic acid or glycerin under your moisturiser tops up water without feeling heavy in the heat.
  6. Rinse off chlorine and salt straight after swimming, then moisturise — both are very drying if left on the skin.
  7. Stay hydrated and protect with clothing — water, a hat and sunglasses all help, especially the delicate skin on your face and around your eyes.
Lighter, not less: Summer is about adjusting texture, not skipping steps. Swap heavy balms for lighter lotions and gel-creams, but keep cleansing gentle and moisturising daily.

How to adjust your routine for summer

You don't need a whole new shelf of products — just dial the textures down. Use a gentle cream or gel cleanser, a hydrating serum, and a lighter moisturiser with SPF in the day. Save richer creams for night if your skin still feels tight. Ease back on strong exfoliating acids and retinoids if your skin is sun-exposed and sensitive, and always layer SPF over everything in the morning. Our full dry-skin routine still applies — you're just choosing lighter formulas.

After sun, pool and sea care

If your skin is dry after a day out, treat it gently: a cool (not cold) shower to rinse off salt, chlorine and sweat, a fragrance-free body wash, then a generous layer of moisturiser on damp skin. For sun-exposed skin, soothing ingredients like aloe vera help — see our natural remedies guide. If skin is genuinely sunburnt (red, sore, blistering), that's skin damage: keep it cool and moisturised, and seek advice for anything severe. And for the tight, dry feeling that lingers, our best moisturisers guide can help you pick a summer-friendly option.

Frequently asked questions

Why is my skin dry in summer?

Summer dries skin through UV damage, air-conditioning, chlorine, salt water and frequent hot showers — all of which strip moisture and weaken the skin barrier. Daily SPF, gentle washing and moisturising on damp skin usually fix it.

Should I still moisturise in summer?

Yes. You may switch to a lighter lotion or gel-cream, but daily moisturising — ideally within a minute of showering — is still important, especially if you use air-conditioning or swim regularly.

Does air conditioning cause dry skin?

Yes. Air-conditioning removes humidity from indoor air much like winter central heating, which increases water loss from your skin. A hydrating mist, regular moisturising and a small humidifier help offset it.

What sunscreen is best for dry skin in summer?

Choose a broad-spectrum SPF 30 or higher in a moisturising or hydrating formula rather than a drying matte one. Creamy or 'hydrating' sunscreens suit dry skin best and double as part of your moisturising step.
