Can the mask be used after being exposed to the sun? Can the mask be used after being scalded with boiling water?

When applying a facial mask, please note that masks are generally stored at room temperature. If the mask is heated too high, it will affect the effectiveness of the mask. Do not apply the mask while taking a bath. It is okay to soak it in warm water before use in winter.

Masks that have been exposed to the sun cannot be used any more. Because many ingredients in the mask need to be stored at low temperature away from light, some of the ingredients in it will deteriorate after being exposed to direct sunlight, and the corresponding skin care effect of the mask will also be weakened, and even some ingredients that are harmful to the skin will be produced, so the mask cannot be used after being exposed to the sun. Because the mask contains many nutrients, it can achieve a good skin care effect. Most of the nutrients in the mask are extracted from plants or added chemical ingredients. Most of these ingredients need to be stored at low temperature away from light, so when we use the mask daily, we should store them in a cool and dry place to avoid direct sunlight. If the mask is placed in direct sunlight or in an environment with high temperature, many ingredients in the mask are likely to deteriorate, which will not only shorten its shelf life, but also weaken the skin care effect of the mask accordingly. Whitening masks that we use daily cannot be exposed to the sun, because many whitening ingredients are sensitive to light. After being exposed to the sun, their structures will change, and the whitening effect will not only be weakened, but may even have a counterproductive effect. Many people put the mask in the refrigerator to better preserve it, but in fact, this practice is not completely safe. If the temperature is too low, the activity of the nutrients in the mask will be reduced. Therefore, if we want to store the mask in the refrigerator, we should soak it in warm water for a while before use to allow the nutrients in the mask to fully exert themselves and avoid the damage to the skin caused by large temperature differences. Of course, we can also apply a hot towel to the face before applying the mask to open the pores of the skin and promote absorption.

If the mask is scalded with boiling water, it will affect the efficacy of the mask. The temperature of boiling water is very high, and some ingredients in the mask may be destroyed. If you want to heat the mask, you can use warm water to heat the mask in autumn and winter. When heating the mask, in order not to destroy the nutrients of the mask itself, you can choose to use warm water and directly put the mask in warm water. The water temperature is 37 degrees, which is about the same as the temperature of the human body. This temperature is also very stable and safe. It only takes about five minutes to soak. The mask heated with warm water must be used in time. Heating the mask may be a method that many people think of, but when using it, they are also unsure whether it will destroy the ingredients of the mask itself. In fact, it is most appropriate for general moisturizing masks to soak in water at a temperature of about 50℃ for 5 minutes. If the temperature is too high or the heating time is too long, the ingredients of the mask will be destroyed. About 50℃ is slightly higher than the normal body temperature of 36.8℃ of the human body, and it is a relatively safe temperature for unstable ingredients. After soaking for 5 minutes, the temperature of the mask will be integrated to a temperature similar to that of the human body, so the effect is the same. After taking a bath in winter, the pores are slightly opened by the heat of steam, and the whole person will feel very comfortable. Lying on the bed and applying a hydrating mask can make the mask work better. Heating the whitening mask will destroy its function. This is because the main ingredients in the whitening mask are unstable. Before applying the mask in winter, you can steam your face with hot air to tighten the pores on your face. Steaming your face is a way to open the pores, which can promote the absorption of nutrients in the mask by the facial skin. To help hydrate the face, moisturizing masks can be heated, but whitening masks cannot be heated. The temperature of hot water should be controlled at around 45°C and heated for a maximum of 5 minutes. If the temperature of the hot water added is too high or the heating time is too long, the nutrients in the mask may be destroyed.

You can apply a hydrating and calming mask.

After being exposed to the sun, the skin on the face will be extremely dehydrated and accompanied by inflammatory reactions, such as redness, swelling and burning pain. At this time, applying a hydrating and soothing mask can quickly replenish water and help repair the damaged stratum corneum. However, whitening and spot-lightening masks are generally acidic, and applying them will increase allergy factors and cause skin rashes. Deep cleansing mud masks often soften keratin and aggravate skin damage. Therefore, in addition to hydrating and soothing masks, it is best not to apply other types of masks.

What to use after cleansing mask

After using the cleansing mask, you should use astringent water to dilute the pores. Because the cleansing mask is mainly used to clean the rough pores on the face, the pores are open after cleaning, so using pore astringent water can better close the pores slightly, which is also the significance of using the cleansing mask. Because the cleansing mask is aimed at the garbage in the skin pores, its ingredients are mainly based on cleaning, but the main focus on cleaning may rely more on the addition of cleaning ingredients, so it may make sensitive skin and dry skin feel uncomfortable. Once the face has burning or itching, it is recommended to stop using this mask immediately and rinse it with water. Although the cleansing mask can clean the garbage in the pores and its cleaning effect is very good, it is not recommended to use it every day. The ingredients added in this mask are relatively fierce, and after cleaning the skin, the stratum corneum may be damaged. Therefore, some sensitive skin or dry skin are not recommended to use cleansing masks, and for mixed oily skin or oily skin, it can be used once a week. If this type of skin uses a cleansing mask too frequently, it will also cause the skin to be over-cleaned and become allergic. Therefore, if the face has excessive oil secretion, you should consider whether it is caused by dehydration. You can first use a hydrating and moisturizing mask for deep care. If it still cannot achieve the effect of oil control and hydration, then it is recommended to use a cleansing mask to clean the pores.
