How long is the shelf life of plain face cream? What are the ingredients of plain face cream?

Su Yan cream is a cosmetic product that many girls use. As cosmetics, they all have a certain shelf life, and the same is true for Su Yan cream. So let's find out how long is the shelf life of Su Yan cream? What are the ingredients of Su Yan cream?

The shelf life of unopened makeup cream is generally three years, and six months after opening. However, the volume of unopened makeup cream is generally small, and it will be used up quickly if used frequently. The oxygen, moisture and bacteria in the air are the key factors that cause the cream to deteriorate. At the same time, you should pay attention to store it well, because improper storage during the shelf life will also cause deterioration. After being exposed to makeup cream, bacteria may multiply due to moisture and certain chemical components, resulting in mold that is invisible to the naked eye. Mold on makeup cream can also cause deterioration. Even within the shelf life, if the product is not stored according to the requirements in the instructions, it will deteriorate. Applying it on the face will cause bacteria to grow on the skin. Unopened makeup cream can not only whiten, but also cover pores, and the effect is the same as liquid foundation.

Ingredient 1: Titanium dioxide. In fact, titanium dioxide is a common sunscreen ingredient and is usually one of the essential ingredients of sunscreen. It can help the skin effectively resist ultraviolet rays. In addition, titanium dioxide also has a certain whitening effect. This makes the natural cream have both sunscreen and whitening effects.

Ingredient 2: Niacinamide. Basically, niacinamide is a type of vitamin, and its scientific name is vitamin B3. Like other vitamin ingredients, vitamin B3 also has good whitening effects and is a rare whitening ingredient in skin care products. The reason why niacinamide can have a whitening effect is that it can stimulate the decomposition of melanocytes, thereby reducing the production of melanin. So the whitening effect of the natural cream comes from this.

Ingredient three: white ginseng and white peony. As two traditional Chinese medicine ingredients in the BB cream, white ginseng and white peony not only have a nourishing effect, but also help the skin regulate water and oil balance, increase skin elasticity, calm and soothe the skin. In addition, they also have a miraculous effect on brightening the skin tone, delaying aging, and improving dull skin.

Ingredient 4: Plant extracts. For example, rose extracts, lavender extracts, etc. These plant extracts not only do not irritate the skin, but their greatest effect is moisturizing and rejuvenating the skin. Some plant extracts also have anti-inflammatory, antibacterial and soothing effects.

Ingredient 5: Hyaluronic acid. I believe most girls have heard of hyaluronic acid. Yes, this ingredient, which is famous for its hydrating and moisturizing properties, also exists in natural creams. It fully replenishes moisture, locks in moisture for a long time, and satisfies the skin's moisture needs throughout the day.

Su Yan cream has excellent brightening, moisturizing and whitening effects, but the concealing degree is not high. Su Yan cream can be used as a primer and used in the last step of basic care. Then use air cushion BB or BB cream to make up the face. Su Yan cream is just a cream containing whitening ingredients, which does not conflict with BB cream. In addition to the general moisturizing ingredients and moisturizing skin care ingredients in Su Yan cream, the most important whitening ingredient is titanium dioxide. Titanium dioxide can cause certain damage to the skin. Ordinary titanium dioxide has large particles, so it will reflect and scatter light when applied to the skin, so you will see your skin become white. Titanium dioxide does have a sunscreen effect, but it takes a layer of titanium dioxide as thick as flour to have a sunscreen effect. In this way, the makeup after applying makeup is as unnatural as a paste, and the complexion is pale.

Most of the ingredients in natural cream are "titanium dioxide", which can be used as a sunscreen, reflecting and scattering ultraviolet rays, so it has a strong ability to resist ultraviolet rays. In addition, it is also "white", but it does not harm the skin like silvering agents. Some natural creams contain silicon, which can fill pores and make them invisible. To put it bluntly, natural cream is a whitening cream that can brighten the skin and belongs to the category of skin care products. But I suggest that you still remove your makeup at night. Although titanium dioxide is harmless to the skin, it may cause pores to be blocked if it stays on the skin for a long time, not to mention that cleaning is very important. So it is recommended to remove makeup before going to bed. Of course, the only advantage of natural cream is that it can also be washed with facial cleanser.
