1. Skin changes that occur during the sweaty season

As we enter May, the temperature and humidity gradually rise, which can easily disrupt the balance of moisture and oil in the skin. This is especially true during the day, when we sweat more and our sebum secretion becomes more active. Many people may find that their face is more prone to becoming shiny, their pores more visible, and their skin is more rough.

This "sweaty season" is a surprisingly delicate time for the skin. Not only do changes occur on the surface of the skin, but the moisture content of the stratum corneum and the activity of the sebaceous glands also change with the seasons, so many people find that their current skincare routine suddenly no longer suits them.

If you notice signs like "my skin seems a bit unstable" or "my skin is getting more oily even though I'm using the same skincare routine as usual," one thing you can do is reassess your approach to washing your face.


2. What is the relationship between sebum and skin balance?

Sebum plays an important role in protecting the surface of the skin and preventing moisture from evaporating. However, excessive secretion can also cause clogged pores, oily skin, and rough skin.

This balance can easily be disrupted by changes in the outside air or skincare habits. For example, if you remove too much sebum by using a strong cleanser or washing your face too frequently, your skin will try to compensate by producing more sebum instead. This creates a vicious cycle of sebum imbalance.

Furthermore, it is said that the properties of sebum change with the seasons. In summer, sebum becomes more susceptible to oxidation, which can cause dull skin and acne. Therefore, rather than simply "removing" it, it is important to think about how to "adjust" it.


3. The vicious cycle of over-washing

"I'm concerned about sebum, so I want to wash it thoroughly" -- that feeling is understandable. However, if you use a strong cleanser to completely remove sebum, your skin will temporarily dry out, and you'll likely fall into a vicious cycle of producing more sebum to compensate for that dryness.

If this condition continues, the balance of sebum and moisture will be disrupted, and not only will your skin become more prone to greasiness, but it will also be prone to a variety of other problems such as dryness, roughness, and clogged pores. Especially during this season, when the effects of ultraviolet rays are compounded and your skin is more likely to become sensitive, you should avoid washing more than necessary.


4. Why cold process soap is gentle on the skin

THE COLD PROCESS soaps are made using the "cold process" method, which involves slowly aging the soap at low temperatures without adding heat. The greatest feature of this method is that natural moisturizing ingredients (especially glycerin) remain in their natural form in the soap.

Glycerin helps keep skin moisturized, preventing tightness after washing and leaving skin feeling moisturized. Another great feature is that it does not contain synthetic surfactants, preservatives, or synthetic fragrances, and can keep skin clean using only the power of the ingredients.

Cold process soap is a face wash that is gentle yet functional, without removing too much sebum.


5. A face-washing routine to incorporate during the hot season

Washing your face twice a day, morning and night, is the basic rule, but during this time of year, try to keep the following points in mind:

  • Morning face wash: A "reset face wash" gently removes sweat and sebum that accumulates while sleeping. The trick is to wash with a gently lathered lather while minimizing friction.

  • Nighttime face wash: Thoroughly remove sunscreen, dirt from the outside air, and sebum. If you wear makeup, double cleanse with cold process soap after cleansing.

  • After washing your face: Gently remove moisture without rubbing with a towel and immediately moisturize.

Also, if you find yourself washing your face multiple times a day when you sweat, we recommend that you reconsider how many times you use face wash and create a time of day when you only need to reset with lukewarm water.


6. Common mistakes and recovery methods

Case 1: Skin becomes tight and peels after washing too much

This is a common case of overly eagerness to cleanse. It's a sign that you've removed too much sebum, causing the stratum corneum to peel easily. By gently washing with cold process soap and thoroughly moisturizing, you may see signs of recovery within a few days to a week.

Case 2: Pores become clogged due to insufficient face washing, leading to acne

Even if you choose not to use a facial cleanser to be kind to your skin, if you continue to do so in the wrong way, dirt can easily remain, causing clogged pores and inflammation. At night, lather up thoroughly and use a gentle soap with cleansing power to remove dirt.

Case 3: Skin becomes red due to a facial cleanser that is not suitable for your skin type

Cleansers containing alcohol, synthetic fragrances, and scrubs can be harsh on sensitive skin. If you experience sensitivity, try switching to cold-process soap with simple ingredients for a gentler skincare routine.

8. Summary

The sweaty season is a time when skin is prone to breakdown. Washing too much because oil production increases can actually disrupt the skin's balance. The appeal of cold process soap is that it is gentle yet thoroughly removes necessary dirt, achieving that balance.

By reviewing your face washing routine, your skin will definitely change. Don't forget to have a "dialogue" with your skin as part of your daily routine. Why not try the gentle, toned face wash of May?
