Hot + Humid

Tropical Climate

WHAT EXACTLY CHANGES IN THE SKIN: First, the skin’s temperature control initiates heat release by expanding its blood vessel closer to the surface. This is why you look rosy and flushed when it’s hot. Second, it initiates the sweat glands to transfer water to the surface in the form of perspiration. The excessive humidity stops the sweat from quickly evaporating, limiting the desired cooling effect, and trapping the wetness on your skin. This is why 80⁰F in a humid climate feels more like 90⁰F.

The lipids, found naturally in the skin, then turn from waxy to oily when skin releases heat. Mixed with the trapped sweat, pores get clogged and break outs accelerate. Your skin starts to reduce its Natural Moisturizing Factor (NMF) production as it gets too much hydration. Additionally, strong UV light and heightened pollution by hot and humid air, create free radicals in the skin, which leads to inflammation, barrier dysfunction and the appearance of aged skin.




Desert Climate

WHAT EXACTLY CHANGES IN THE SKIN: The drier the air, the more moisture it sucks from your skin. This naturally occurring process is called Transepidermal Water Loss (TEWL). In a humid climate, the loss of water is replaced by water from the humid air but in a dry climate, your skin can’t completely replace the water loss. Combined with the hot temperatures, which the skin controls by releasing heat and activating perspiration, skin turns dry soon. In low humidity, sweat quickly evaporates, thus cooling down skin. This is why 80⁰F in a dry climate feels more like 70⁰F.

To counteract dehydration, your skin increases it’s Natural Moisturizing Factor (NMF) to safely pull water from inside the body. Skin only receives 30% of water from the dermis, as it would normally get enough from humid air.  Lipids provide oil to the skin but the lack of hydration from the atmosphere often causes skin to lose its moisture balance.  Strong UV light and pollution, heightened in this extreme climate, create free radicals in the skin, leading to inflammation, barrier dysfunction and the appearance of aged skin.




Polar Climate

WHAT EXACTLY CHANGES IN THE SKIN: Your skin struggles in cold weather. Chilly temperatures force the skin’s blood vessels to constantly change their behavior. They expand and constrict to manage the trade-off between driving warm blood to the organs and keeping the skin supplied. Your body eventually reduces blood flow to your skin when temperatures drop below 45⁰F.  Once this happens, skin’s vessels dilate and stretch wider, so they can be more efficient. This is why your face often looks red in polar conditions.

Some blood vessels stretch out beyond their usual capability.  This is known as broken capillaries and can also happen to your skin when suddenly going from the cold to overheated rooms and vice versa. In addition to the cold, the lack of humidity in the air accelerates Transepidermal Water Loss (TEWL) forcing the Natural Moisturizing Factor (NMF) to increase production while skin receives less natural oils as the lipids stay waxy. Even when the sun is not visible, UV light is still present and so is pollution, creating free radicals in your skin, accelerating external aging and barrier dysfunction.




Temperate Climate

WHAT EXACTLY CHANGES IN THE SKIN: Temperate climate is the base line. In this mild climate condition when humidity and temperatures are about average, your skin is relaxed and clinical studies have confirmed, it functions at ease.

In temperate conditions, your skin actually benefits from the climate in terms of hydration. The powerful humectants which are part of the Natural Moisturizing Factor (NMF) draw in the optimal amount of atmospheric water for your skin to stay naturally moist and balanced. The skin barrier is less challenged by pollution and UV light than in extreme climates, as this mild climate won’t accelerate their negative effects. Yet, they still exist and contribute to the creation of free radical damage which can compromise healthy barrier function.

THE SOLUTION: Temperate Day Cream

Skin Science Spotlight #3:

NMF is Skin’s Natural Climate IQ

Climate-Smart® skincare learned from the best: the skin

1. Skin’s Natural Moisturizing Factor (NMF) is built to adjust and change to the climate you’re in. In the same respect, Climate-Smart® skincare formulations are developed to address the needs of your skin in each climate situation. No matter where you live, your skin has adjusted to your particular environment by either increasing or reducing its production of NMF. Climate-Smart® skincare works because each cream has key ingredients to protect and hydrate skin per climate. Each Day Cream contains a certain amount of NMF-identical ingredients which help to advance skin’s hydration levels, making it the optimal way for your skin to find its delicate moisture balance in every climate consistently.

2. Pour Moi’s innovative HyalurTruf+ complex is a new Climate-Smart® ingredient system which mimics the Natural Moisturizing Factor. The NMF is a group of humectants and amino acids, produced by the outer skin, to increase hydration in the outer layers. They naturally attract water like a magnet from the sky and/or from the dermis depending on the humidity available in the air. HyalurTruf+™ works likewise.  Made from a blend of advanced Hyaluronic acids, varying in molecule weight, and luxurious amino acid-packed White Truffle extract, HyalurTruf+™ is the key to Climate-Smart® beauty technology. Depending on the two core climate factors, temperature and humidity, the HyalurTruf+™complex in each Pour Moi product is expertly paired with unique hydrators (humectants, botanicals and emollients) to provide the ideal biomimetic textures for optimal hydration per climate.

3. Pour Moi is biomimetic – which means it imitates a biological function of the skin. In the case of our Day Creams, they’re able to effectively stimulate hydration like NMF so skin looks naturally glowing and healthy.

4. Pour Moi Day Creams include non-comedogenic occlusive ingredients for moisture protection per climate; and active ingredients for barrier restoration like retinol (vitamin A), vitamin C and vitamin E.
