Habits that Break Down the Skin Barrier During Seasonal Changes: Caution Against Exfoliation and Excessive Oil Supply

During periods of seasonal change when rapid temperature fluctuations weaken the skin barrier, common incorrect management habits can worsen skin conditions. In the video 'Yak-jeul-si Season 7 EP4' from the Ministry of Food and Drug Safety's official channel, pharmacist Kim Jeong-eun and director Shin Seung-yong appeared to explain habits that harm skin health during seasonal changes and proper management methods.

The Impact of Exfoliation and Excessive Oil Supply on the Skin

The phenomenon of skin turning white and flaky during seasonal changes is a signal that the skin's protective layer is damaged and lacking moisture. The video advises avoiding physical irritation, such as using harsh scrubs or bath towels, to manage the skin during this period. If skin surface dead skin cells are a concern, it is recommended to use AHA, a water-soluble ingredient, to gently dissolve them. On the other hand, if there are sebum issues inside the pores, BHA, an oil-soluble ingredient, may be helpful.

To resolve the 'oily yet dehydrated' (oily skin with insufficient moisture) state, where the skin surface is shiny but feels tight inside, caution is also needed regarding the habit of applying excessive oil creams or oils. According to the video, not all creams and oils clog pores; it depends on the ingredients, texture, and amount used. It is important to use them appropriately only on the necessary areas according to skin type.

'Skip Care' and Ingredient Selection When the Skin Barrier is Damaged

If symptoms such as redness or stinging appear, there is a possibility that the skin barrier has weakened or allergic dermatitis has occurred. In this case, even functional products that were previously used safely, such as high-concentration Vitamin C ampoules, can irritate the skin. The video recommended 'skip care'—focusing on mild cleansers and moisturizers—instead of forcing the use of all products when the skin is in a sensitive state.

Ingredients that help soothe the skin, such as panthenol or adenosine, were mentioned. However, since plant extracts can cause allergic reactions depending on the individual, it is good to test them behind the ear before applying them to the entire face. If there is redness, swelling, or severe itching on the skin, it is necessary to stop using cosmetics and receive a diagnosis from a dermatologist.

Precautions for Washing with Hot Water and Using Mists

Habits such as washing with hot water due to cold weather or frequently using mists can also cause skin dryness. This is because washing with hot water for too long can strip away the skin barrier. When using a mist, it is more effective to choose products containing ingredients that hold moisture, such as glycerin or hyaluronic acid, rather than simple hydration.

It is important to apply moisturizer immediately after washing or using a mist to block moisture from evaporating. Through this video, the Ministry of Food and Drug Safety concluded the Season 7 series by emphasizing the protection of the skin barrier as the most basic management method for maintaining skin health during seasonal changes.
