What Causes Dry Skin In Winter?

The main factors that determine a person's natural skin color are genetics and the amount of melanin present in their skin. Cold air itself does not directly make your skin lighter in terms of pigmentation.  

However, exposure to cold air and reduced sunlight can indirectly contribute to a temporary lightening of the skin's appearance due to various factors:

• With less sun exposure, there might be a temporary reduction in melanin production, resulting in a lighter appearance.
• Less outdoor time will also reduce sun-induced tanning.
• The dry skin accumulation is more in the cold season and therefore exfoliating them gives the skin a lighter appearance.
• In a study, they investigated the effects of temperature change on melanogenesis in a mouse melanocyte cell line (Mel-Ab) and primary cultured human melanocytes and found that Mel-Ab cells cultured at low temperatures (31 and 34 degrees C) produce less melanin than cells at 37 degrees C. 

A moisturiser is essential in the beauty regime. But sometimes it causes a stinging sensation.

• A stinging sensation after applying moisturiser is most likely the result of a compromised skin barrier.  
• Best moisturisers for dry skin may also contain ingredients like fragrances, preservatives, certain acids etc., that cause sting on application.
• Also, if the product being applied has a particularly low pH,  it is very acidic, like certain AHAs (glycolic acid) or vitamin C, it causes a stinging or burning sensation.
• Skin inflammation also contributes to the stinging sensation. 

How to take care of skin in winter naturally is a main worry among beauty buffs. These natural remedies can be applied as a mask or directly used and are gentle on the skin and help to hydrate and nourish it.  

• Coconut oil is a natural emollient that can help lock in moisture. Apply a small amount to damp skin after bathing.
• Honey is a natural humectant that can attract and retain moisture.
• Olive oil is rich in antioxidants and healthy fatty acids.
• Aloe vera has soothing and hydrating properties.
• Shea butter is a natural fat extracted from the nuts of the shea tree. It's rich in vitamins and fatty acids that can deeply moisturize the skin.
• Rosewater is a natural toner that can help balance the skin's pH and provide a light, refreshing layer of hydration.
• Avocado is packed with healthy fats and antioxidants that nourish and hydrate the skin. 

Coconut oil is a natural emollient that can help lock in moisture. It is considered the best winter moisturiser for dry skin as it can help decrease transepidermal water loss (TWL). Coconut oil is a safe and effective moisturizer for conditions like xerosis or rough and dry skin.  

Virgin coconut oil contains higher amounts of nutrients such as vitamin E and bioactive compounds such as polyphenols (plant materials that have antioxidant properties). 

Winter skincare for dry skin requires a combination of external skincare practices and internal habits that promote skin health. A few options that help are:

• Opt for a moisturizer that contains humectants (like glycerin and hyaluronic acid) to attract and retain moisture, as well as occlusive ingredients (like shea butter and natural oils) to prevent water loss.
• Look for products with ingredients like ceramides, fatty acids, and squalene.
• If your skin is extremely dry, consider using a hydrating serum or essence before applying your moisturizer to provide an extra layer of hydration.
• Incorporate hydrating sheet masks or overnight masks into your routine once or twice a week to provide an intense boost of moisture.
• Herbal teas and water-rich foods (like fruits and vegetables) can also contribute to hydration.
• Products containing hyaluronic acid can help attract and retain moisture in the skin.
