How Humidity Affects Your Skin And What You Can Do About It

During spells of hot weather, humidity levels often rise too. While many people associate humidity with frizzy hair, it can also have a significant impact on your skin. 

Depending on your skin type, humid conditions can lead to excess oil, clogged pores, dehydration or even increased sensitivity.

By understanding how humidity affects your skin and making a few simple adjustments, you can help keep your complexion looking healthy, balanced and comfortable throughout the summer.

What is humidity?

Humidity refers to the amount of water vapour in the air. During the summer months, particularly after rainfall or during periods of hot weather, humidity levels can increase considerably.

High humidity affects how your body cools itself. Sweat evaporates more slowly, leaving your skin feeling damp for longer. Combined with sunscreen, makeup and environmental pollutants, this can create conditions that contribute to skin concerns.

Why does humidity change your skin?

Your skin is constantly responding to its environment. Changes in temperature and moisture levels influence how much oil your skin produces and how effectively it retains water.

In humid weather, you may notice:

• Shinier skin than usual
• Increased sweating
• Enlarged-looking pores
• More frequent breakouts
• A sticky feeling on the skin
• Makeup that doesn't last as long

However, not everyone experiences humidity in the same way. Your skin type plays an important role in how your complexion reacts.

Humidity and oily skin

If you naturally have oily skin, humidity can increase sebum production even further. Combined with sweat, excess oil can mix with dead skin cells and block pores.

This may lead to:

• Blackheads
• Whiteheads
• Spot breakouts
• A greasy appearance
  

Rather than trying to strip away every trace of oil, it's better to maintain balance. Over-cleansing or using harsh products can actually encourage your skin to produce even more oil.

Choose a gentle cleanser that removes impurities without disrupting your skin's natural protective barrier.

Humidity and dry skin

It may seem surprising, but people with dry skin can also experience problems in humid weather.

While humid air can temporarily reduce moisture loss from the skin, factors such as air conditioning, sun exposure and frequent washing can still leave skin feeling dehydrated.

Dry skin during summer may feel:

• Tight
• Rough
• Sensitive
• Less comfortable after spending time outdoors

Using lightweight moisturisers with natural hydrating ingredients can help maintain softness without feeling heavy.

Sensitive skin can become more reactive

Heat and humidity may trigger flare-ups in people with sensitive skin. Sweat trapped against the skin can sometimes contribute to irritation, particularly around areas where clothing rubs or where sunscreen and skincare products build up.

Look for natural sensitive skincare products, which contain ingredients known for their soothing properties, such as aloe vera, chamomile and oat extract. This can help calm skin that feels overheated or uncomfortable.

Should you moisturise less in humid weather?

One common misconception is that moisturiser is unnecessary during the summer. In reality, your skin still needs hydration. The difference is that heavier creams used during winter may no longer feel suitable.

Instead, switch to lighter formulations that absorb quickly while helping the skin retain moisture.

Ingredients that work well during humid weather include:

• Aloe vera
• Jojoba oil
• Grapeseed oil
• Plant-derived squalane
• Hyaluronic acid

These ingredients provide hydration without leaving the skin feeling greasy.

Cleanse gently, not more often

Sweating more doesn't necessarily mean you should wash your face constantly. Excessive cleansing removes your skin's natural oils, which can weaken the skin barrier and encourage additional oil production.

For most people, cleansing twice daily is sufficient:

• Once in the morning to refresh the skin
• Once in the evening to remove sunscreen, sweat, pollution and makeup

If you've exercised or spent a long time outdoors, rinsing with cool water before your evening cleanse can help you feel more comfortable.

Don't forget sun protection

Humidity doesn't reduce the effects of ultraviolet (UV) radiation. Even on warm, cloudy days, your skin is still exposed to UV rays that contribute to premature ageing and pigmentation.

Apply sunscreen every morning as the final step in your skincare routine, and reapply if you're spending extended periods outdoors. Choosing a lightweight sunscreen that suits your skin type can help reduce the feeling of heaviness in humid weather.

Enjoy healthy skin whatever the weather

Humidity affects every skin type differently, but understanding how your skin responds allows you to adapt your routine without overcomplicating it.

By cleansing gently, choosing lightweight natural sensitive skincare products, staying hydrated and protecting your skin from the sun, you can help maintain a balanced complexion throughout the warmer months.
