How does heat and humidity affect your regimen?

Heat and humidity can throw a wrench in your skincare routine. They can change how your skin behaves and how your products perform. Let's get into the nitty-gritty of why this happens and how your skin can stay balanced without having to go through any strange hats, backed by science and expert advice.

How Heat and Humidity Affect Your Skin

The Impact of Heat

Heat ramps up your body’s temperature, making you sweat more. Here’s what happens next:

  • Increased Oil Production: Your sebaceous glands kick into high gear, producing more oil. This excess oil can mix with sweat, leading to clogged pores and breakouts.
  • Dehydration: Water evaporates from your skin faster in the heat, leaving it parched. This can make your skin feel dry and highlight fine lines.
  • Inflammation: Heat can worsen inflammation, especially if you have conditions like rosacea or eczema. The blood vessels in your skin expand, causing more redness and irritation.

Dr. Joshua Zeichner, Director of Cosmetic and Clinical Research in Dermatology at Mount Sinai Hospital, often advises patients to use "lightweight, oil-free products that won’t add to the problem" in hot and humid weather.

The Impact of Humidity

Humidity is the amount of water vapor in the air, and it can be a double-edged sword:

  • Moisture Retention: High humidity helps your skin stay hydrated by reducing water loss. However, for individuals with oily skin, this can sometimes make their skin feel excessively sticky or greasy.
  • Bacterial Growth: The damp environment is a breeding ground for bacteria and fungi, increasing the risk of infections and acne.
  • Barrier Disruption: Prolonged exposure to sweat and friction in humid environments can weaken your skin’s barrier, making it more prone to irritation.

Dr. Audrey Kunin, a board-certified dermatologist, highlights the challenges humidity brings to skincare. She states, "Humidity envelops skin in a blanket of heat and moisture, which leads to pores expanding wide, an increase in oil production, and a smothering of the skin. This can lead to congestion or even an outbreak of blemishes".

How Skincare Products Interact with Skin in Heat and Humidity


Your skin’s needs change in hot and humid conditions.

  • Hydrating Ingredients: Humectants like hyaluronic acid and glycerin draw moisture from the air. While this is great for hydration, it can make your skin feel too sticky in high humidity.
  • Occlusives: Heavier moisturizers containing occlusives like petrolatum can trap sweat and oil, worsening acne and causing a greasy feel. Lightweight, non-comedogenic moisturizers are a better choice.


Sunscreen is a non-negotiable, but it needs to be chosen wisely.

  • Sweat Resistance: Heat and activity increase sweat, which can wash away sunscreen. Water-resistant formulas are essential for lasting protection.
  • Pore-Clogging: Heavy sunscreens can clog pores, especially in hot, humid weather. Look for non-comedogenic and mattifying sunscreens to keep shine at bay.


Cleansing is critical to remove excess oil, sweat, and dirt.

  • Gel-Based Cleansers: These are ideal for removing excess oil and sweat without stripping the skin of its natural moisture.
  • Avoid Over-Cleansing: Over-cleansing can disrupt your skin’s barrier, leading to more oil production and breakouts.

Stability of Products

Heat and humidity can mess with the stability and efficacy of your skincare products.

  • Active Ingredients: Ingredients like vitamin C and retinoids degrade faster in high temperatures, reducing their effectiveness. Store products in a cool, dry place to maintain their potency.
  • Preservatives: High humidity can promote microbial growth in products. Effective preservatives are essential to keep your products safe. Always ensure your products are sealed tightly and stored properly.

Understanding how heat and humidity impact your skin and skincare products is crucial for maintaining healthy, balanced skin. Adapting your routine to the weather and your skin type helps manage these environmental challenges. Lightweight, hydrating products are essential in summer to avoid clogged pores, while richer, barrier-repairing products are key in winter to combat dryness.

To streamline your skincare routine and address your skin's specific needs, consider incorporating a comprehensive set like GOA's Essential Set, designed to cleanse, nourish, and protect your skin from environmental stressors.
