Is Using Nan Chiao Soap for Facial Cleansing Safe?

Inquiry about using Nan Chiao soap for washing the face?

A friend mentioned that the South China soap we used for laundry is said to make the face and skin feel very smooth.
Although a close friend emphasized that the results are good, I would like to consult Dr.
Zheng first before trying it.
While it may not be a matter of physical discomfort, I believe it's better to take precautions than to address skin issues after they occur.
I trust your expertise and hope you can provide me with an answer.
Thank you very much.

Nanqiao soap has become a popular and affordable cleansing product due to its simple ingredients, effective cleansing power, and gentle nature on the skin.
Nevertheless, it is important to adhere to the principle of not overusing it, and the water temperature should not be too hot, in order to protect your skin.

More Info

Using Nan Chiao Soap for facial cleansing can be a topic of debate among dermatologists and skincare enthusiasts. While some people may find it effective due to its simple ingredients and cleansing properties, it is essential to consider several factors before incorporating it into your skincare routine.

Firstly, Nan Chiao Soap is primarily marketed as a laundry soap, and its formulation is designed for cleaning fabrics rather than human skin. Although it may contain fewer harsh chemicals compared to some commercial soaps, the pH level and specific ingredients may not be suitable for facial skin, which is more sensitive than the skin on the body. The skin on your face has a natural barrier, known as the acid mantle, which helps protect against environmental aggressors and maintains moisture. Using a soap that is not specifically formulated for facial use could disrupt this barrier, leading to dryness, irritation, or even allergic reactions.

Moreover, the texture and composition of laundry soaps can vary significantly from facial cleansers. While some users report that Nan Chiao Soap leaves their skin feeling smooth, this sensation may not be indicative of a healthy cleansing process. A good facial cleanser should effectively remove dirt, oil, and makeup without stripping the skin of its natural oils. If a soap is too harsh, it can lead to over-drying, prompting the skin to produce more oil in response, which can exacerbate issues like acne.

When considering any new product for facial cleansing, it is crucial to perform a patch test first. Apply a small amount of the soap to a discreet area of your skin, such as behind your ear or on your wrist, and monitor for any adverse reactions over 24 hours. If you experience redness, itching, or irritation, it is best to avoid using the product on your face.

Additionally, dermatologists often recommend using products that are specifically designed for facial cleansing. These products typically have a balanced pH, are free from harsh detergents, and include moisturizing ingredients that can help maintain the skin's hydration levels. Look for cleansers that are labeled as "gentle," "non-comedogenic," or "suitable for sensitive skin," as these are more likely to be safe for facial use.

In summary, while some individuals may have had positive experiences using Nan Chiao Soap for facial cleansing, it is generally advisable to use products specifically formulated for the face. The risk of irritation, disruption of the skin barrier, and potential allergic reactions outweigh the benefits of using a product not designed for facial care. Always prioritize your skin's health by choosing appropriate products and consulting with a dermatologist if you have any concerns or specific skin conditions.
