The facial cleanser has become thinner after being exposed to the sun

Facial cleanser is solid when stored at room temperature, but it will become very thin after being exposed to high temperature. This is because the facial cleanser melts after being exposed to high temperature. It needs to be kept in the refrigerator and not exposed to direct sunlight. It should be placed in a dry and cool place to ensure product quality. If it is exposed to the sun for too long, the quality will be affected and the effect will not be achieved.

For skin care products such as toner, astringent, etc. that replenish water and balance the acidity and alkalinity of the skin, it is best to tighten the cap and put them in the refrigerator. Toner products can also be put back into the original packaging and stored in the refrigerator. However, it should not be stored for a long time and should not be taken in and out every day, especially new whitening products containing active ingredients such as vitamin C, which can easily be oxidized or deteriorate due to temperature.

However, not all skin care products are most reliably kept fresh in the refrigerator. If oil-based skin care products are kept in a low temperature state for a long time, oil and water separation will occur, the texture will become rough, the shape will diverge, and they may even lose their skin care effects and cause irritation to the skin. Therefore, do not expose products such as facial cleansers, cleansing creams, day creams, night creams, functional creams, etc. to direct sunlight. Just keep them in a cool, dark place to ensure product quality.

It mainly refers to a series of products used for makeup, such as eye shadow, rouge, etc. Strong ultraviolet rays have a certain penetrating power, which can easily cause oils and fragrances to oxidize and destroy pigments. Therefore, cosmetics should be stored away from light. It should be placed in a place where the temperature is below 35°C. In addition, during the rainy season, cosmetics must be protected from moisture. An overly humid environment will accelerate the reproduction of bacteria in cosmetics containing proteins and lipids, causing them to deteriorate. Some cosmetic packaging bottles or box lids are made of iron, which are easy to rust when exposed to moisture, corroding the cream in the bottle and causing it to deteriorate. Cosmetics should be stored in a ventilated and dry place.
