Can a moisturizing cream still be used after one year? What are the main ingredients of a moisturizing cream?

In autumn and winter, the weather is getting drier and drier, so female friends should do a good job of moisturizing. Moisturizing cream is a good choice to keep the skin moisturized and not flaky. Many friends have opened moisturizing cream but have not used it much. In this case, can it still be used after a year?

No. Moisturizing cream cannot be used after one year of use. The ingredients in the cream will change when exposed to air, and it will be harmful to the skin if used again. It is recommended to use up the opened cream within three months. If you continue to use it, it will not only harm the skin, but also lose its original efficacy.

What are the main ingredients of moisturizing cream?

Polydimethylsiloxane and petrolatum, hyaluronic acid and glycerin. Polydimethylsiloxane can form a protective layer on the skin surface, moisturize the skin and retain moisture, reducing keratin exfoliation. Vaseline can soften the skin and prevent roughness and flaking. Hyaluronic acid and glycerin play a super hydrating role.

What are the types of facial creams?

1. Moisturizing cream

The most important thing to pay attention to when using a moisturizing cream is the water content and water retention. High water content allows the cream to penetrate the skin evenly and easily and be absorbed easily. Water retention allows the ingredients that moisturize the skin to be easily retained and not easily evaporated, thus maintaining a certain water content in the skin. Of course, you must be careful not to use too much synthetic fragrance, as too much can easily cause allergies.

2. Anti-aging cream

These types of creams must have a rich texture, be easy to spread and absorb, and have a glossy feel when applied, because those who need such products are generally within a fixed age range, and must contain antioxidant and anti-aging ingredients, such as green tea, such as peptides and other ingredients. Effective active ingredients can help the cream achieve good results. Anti-aging creams must contain elastic fibers and collagen, so that they can play a role in repairing and anti-aging.

3. Whitening cream

It is said that whitening is necessary all year round, but it is recommended that whitening products should be used at night, because whitening products are less effective in moisturizing and may not be enough during the day. It is better to choose according to different skin types. As for sensitive skin, it is better to choose milder products.

How to choose facial cream

Dry skin is suitable for using creams and more moisturizing lotions, while oily and combination skin is suitable for refreshing lotions and oil-free creams. In dry seasons, such as autumn and winter, it is suitable to use thicker creams.
