What is the real reason my skin becomes more sensitive in winter?

As temperatures drop and the air becomes drier, many people notice that their skin feels more sensitive and prone to irritation during the winter months. Why? Low humidity and cold air can strip the skin of its natural moisture and make the skin produce less sebum, while indoor heating just dehydrates skin even further. Plus, just those rapid temperature changes themselves - from the freezing weather outside to going inside somewhere warm - can trigger redness and discomfort. And that’s not all, with reduced sunlight exposure also affecting the skin barrier and its ability to repair itself, leaving it more vulnerable to dryness and sensitivity.

 

Solutions and swaps

Fortunately, there are effective ways to soothe and protect a damaged skin barrier. Using a humidifier indoors helps maintain optimal moisture levels in the air, while drinking plenty of water keeps skin hydrated from within. Switching to shorter, lukewarm showers instead of long, hot ones, and avoiding harsh soaps prevents further skin barrier damage.

As for your skincare routine? Focusing your regimen on barrier repair and deep hydration can make a big difference in how your skin feels and looks. Incorporate products rich in ceramides, hyaluronic acid, and gentle antioxidants, which strengthen the skin barrier and

lock in moisture, as well as soothing ingredients like fermented rice extract, panthenol, or allantoin, which helps calm sensitivity and prevent inflammation.

Keep reading for our winter skincare routine for your face and body, which will help your skin become more resilient to harsh winter conditions, and maintain hydration, comfort, and a smooth, even texture.

 

Your winter routine for your face and body

Black Rice Hyaluronic Toner (Free of Alcohol & Fragrance)

Your dry skincare routine starts with cleansing, and then applying the Black Rice Hyaluronic Toner (Free of Alcohol & Fragrance). It delivers the same intense hydration and brightening results as the original, now in an even gentler formula designed for sensitive skin. Rather than using the rice extract found in many K-beauty toners, this formula harnesses the power of fermented black rice extract, making it twice as effective with its moisturizing, antioxidant and nourishing properties.

With its ultra-light texture, this Korean rice toner absorbs instantly, leaving skin soft, radiant, and deeply hydrated without any sticky residue. Clinically tested for sensitive skin, the formula features a potent blend of hard-working ingredients, including fermented oryza sativa extract to brighten and moisturize, shoot bark extract to soothe irritation, hyaluronic acid to plump and even skin texture, and betaine to balance oil and hydration levels. Beta-glucan supports skin regeneration and prevents loss of moisture, while red ginseng extract adds immunity-boosting benefits.

After cleansing, pour the product directly into your palm and lightly pat it into the skin until fully absorbed. For an intensive moisture boost, layer it two to three times to lock in lasting hydration.
