Does hand cream have sun protection function? How to judge the quality of hand cream?

Hand cream is a skin care product that we commonly use. Many people have used hand cream, which has a good moisturizing effect on our hand skin. So we need to know whether hand cream has a sun protection function? How to judge the quality of hand cream?

Does hand cream have sun protection function?

Ordinary hand creams cannot protect against the sun. Only hand creams with sunscreen function can protect against the sun. A small number of hand creams have sunscreen effects, but the SPF value is low. If you are exposed to the sun for a long time, you need to apply sunscreen. Sunscreen hand creams have a relatively low SPF value. If you are exposed to direct sunlight for a long time, you still need to use it with sunscreen. There is a wide range of SPF values ​​to choose from, and there are sunscreens with very high SPF values. The main functions of hand cream are exfoliation, moisturizing, anti-aging and anti-cracking. Sun protection is not the main function of hand cream. After all, sunscreen is the main force of sun protection. The focus of hand cream is "protection". After applying hand cream on your hands, wait for ten seconds until the skin has absorbed the hand cream, and then apply sunscreen. Sunscreen should be applied every three hours. After applying sunscreen, you need to remove makeup at night, otherwise it will easily clog your pores.

How to judge the quality of hand cream

1. Moisture. The main concerns when using hand cream are how the cream is absorbed after application and the effect after hydration. A hand cream of better quality will be better at nourishing the skin. This is because the essential oil molecules in a good hand cream are smaller, so the effect will be more obvious when applied to the hands. Inferior hand creams have coarser essential oil molecules, and their nourishing and absorption effects are significantly worse.

2. Look at the texture of the hand cream. The texture of hand cream determines its nourishing and absorption effects. Hand cream with better texture will feel easy to apply on your hands. After applying it on the hands, the skin of the hands will feel moisturized and thin, while hand creams with poor texture will be sticky and difficult to spread when applied on the hands, and will also feel stuffy and depressing after applying it on the hands.

3. Feel its stickiness. To put it in simpler terms, after applying hand cream, feel the viscosity of the skin on your hands. If your skin feels sticky and clingy, the hand cream will easily be contaminated by dust, bacteria, etc. in the air. If the hand cream feels refreshing and not sticky after applying it, it will not be easily contaminated by dust and bacteria in the air, and will make the skin more delicate and smooth.

Is mineral oil in hand cream harmful?

Mineral oil is carcinogenic, which is the primary reason why mineral oil is harmful to the skin. But this argument does not hold water. Mineral oil: Some petroleum derivatives do contain carcinogens (such as certain polycyclic aromatic hydrocarbons), but mineral oils used in the beauty and pharmaceutical industries are highly refined and purified. Their quality and purity have even reached the approval of the FDA (short for "U.S. Food and Drug Administration") and other international regulatory agencies, so they cannot be confused with those carcinogenic petroleum derivatives. Mineral oil and mineral oil refer to the same thing. Mineral oil is just an incomplete name for mineral oil. It is better at moisturizing and is often used to make hand creams and skin care products. Mineral oil is a hydrocarbon extracted from petroleum. Because it has been highly refined, the composition of mineral oil is relatively simple and it is relatively inert. It is not easy to react when it comes into contact with human skin, reducing the possibility of allergies.

Does hand cream expire?

meeting. The shelf life of hand cream is generally 3 years, that is, calculated from the date of production. It cannot be used after 3 years. After the hand cream is opened, the best shelf life is 1 year, which means it must be used up within 1 year after opening to avoid affecting the effectiveness of the hand cream. Also, you cannot use hand cream that has expired. Once the hand cream is opened, it has been exposed to microorganisms and bacteria in the ambient air and will also be oxidized by the air. Gradually, the effective ingredients in the hand cream will gradually lose their effectiveness and eventually rot.
