Can facial cleanser still be used after being heated to high temperature?

Facial cleanser is a commonly used cleaning product. It can clean the skin very well. However, many people only know that facial cleanser can remove dirt from the face when using it, but they don’t know about some precautions. For example, many people wonder whether high temperature will affect the effect of facial cleanser. In fact, the effect of temperature on facial cleanser is relatively small, but long-term exposure to high temperature still has side effects. It is easy to deteriorate and cause water and emulsion separation. Therefore, it is best to put it in a ventilated and dry place to ensure better use effect.

The highest temperature that general facial cleansers can withstand is 48 degrees. If it exceeds this temperature, the water and lotion will separate. For example, the sunscreen I used before was accidentally placed in a high temperature place, and the color turned yellow, and the water and lotion separated. I no longer use it. But my classmate also had a similar experience~~Her facial cleanser was also affected by the heat, but later she put the facial cleanser in the refrigerator~~The magical thing is that the facial cleanser returned to normal. I think if you are exposed to heat for a short time, just ice it back, but if it lasts for a long time, it is best not to use it~~

In fact, they will not go bad in a short period of time. After all, they can be kept at room temperature and do not need to be refrigerated, so don't worry. You can also carefully observe whether the texture of the facial cleanser has any abnormal changes, whether there are any lumps, changes in taste, or changes in color. If there are none of these, it's okay.

If the properties have not changed, it can be used. If the color has changed or there is an odor, it means it has deteriorated and cannot be used. In addition, facial cleanser should be stored at room temperature away from light.

Directions:

Take a proper amount of water and splash it on your face to moisten it. Take a proper amount of facial cleanser (usually 3 to 5 cm) on the palm of your hand, add water and rub until it forms foam. Apply it on your face and massage for one minute, then rinse it off with clean water.

When using, wet your face first, then squeeze an appropriate amount of facial cleanser on your forehead, nose tip, cheeks, and then on your hands, gently rub it, and then massage your face in circles from bottom to top and from inside to outside for a few minutes. Pay attention to cleaning the T-zone and U-zone where dirt is easily hidden, then rub it with clean water, gently massage for half a minute, and then wash it off.

Notice:

Facial cleanser is one type of cleansing product. Others include facial soap, facial powder, facial mousse, cleansing water, etc., depending on the dosage form.

Because facial cleansers do not stay on the face for a long time, even though moisturizing, nourishing, whitening and other ingredients can be added, they cannot stay on the skin for a long time and it is difficult to fully exert their claimed functions. For example, if you have a strong moisturizing demand, you need to use moisturizing cream or essence in the subsequent steps to better exert the moisturizing effect.

Moisturizing facial cleansers often add ingredients such as glycerin, butylene glycol, potassium glycyrrhizinate, lactic acid, sodium hyaluronate, etc. to achieve the purpose of being gentle and non-irritating during cleansing, and moisturizing without drying out the skin after cleansing.
