Is it good to use the same skin care product for a long time?

Many makeup novices think that makeup is very important, and thus invest a lot of money in purchasing makeup. In fact, for makeup and beauty, skin care is a more critical step. As long as you take good care of your skin, many cosmetics will have better effects. But how to choose skin care products is a problem that many women are very distressed about. Many women have questions: Is it good for the skin to use a skin care product for a long time?

I often hear that you shouldn’t use the same skin care product continuously for a long time, as the harmful substances in the product will be deposited in the skin. This is bad for the skin and will cause dependence. You should regularly switch to different brands of products. Does this make sense?

Harmful substances in skin care products

The harmful substances in cosmetics mentioned here are not ingredients deliberately added by merchants, but some harmful substances residues will be mixed in during the raw material production process due to the limitations of production technology, such as heavy metals such as mercury, lead, arsenic, and the "dioxin" that everyone is afraid of. Don't worry about these residual ingredients. The country has strict regulations on the residue content in raw materials. The content is very low and will not cause harm to the skin.

These residual substances are negligible compared to the amount we are exposed to in our daily diet and air, and will not cause harm to the skin even if used for a long time. Moreover, the residues in the raw materials are similar for every brand, and changing brands cannot avoid these residues. These residues are not a reason to replace products regularly.

So, is it possible to use a product continuously for a long time? Not really. Some products can be used for a long time, while some products need to be discontinued after a period of time. Below, Zhen Yao will explain several situations.

Cleaning Products

The main function of cleaning products is to clean facial dirt and keep facial skin clean. For most skin types, choosing a mild amino acid facial cleanser or alkyl glycoside facial cleanser can meet the cleansing needs. It can be used for a long time and basically does not need to be replaced.

However, for some people with very oily skin, it is necessary to adjust the cleansing products in time according to the changes in seasons and climate. For example, in the hot summer, oil secretion is too strong and amino acid facial cleanser cannot clean thoroughly. At this time, you can use soap-based and SLES surfactant cleaning products at night, and amino acid facial cleanser in the morning. In cold seasons, oil secretion will decrease, and a bottle of amino acid facial cleanser can meet the needs. If oily skin uses soap for a long time, it can easily cause the skin and cheeks to become dry, sensitive, and even have red blood streaks.

For some extremely dry sensitive skin or skin with red blood streaks, even using amino acid facial cleansers may feel dryness in cold seasons. At this time, you need to use a foam-free facial cleanser, or even just wash your face with clean water in the morning. When the weather is hot, foam-free facial cleansers may not be strong enough to cleanse, so it is best to choose an amino acid facial cleanser for evening cleansing.

Moisturizing products

The basic principles of moisturizing products are to work from two aspects. 1. Supplement some water-soluble small molecule water-locking ingredients. These ingredients are components of the intercellular matrix and can enter the skin to exert their ability to lock in water. 2. Form a protective film on the surface of the skin to prevent moisture evaporation. No matter which moisturizing ingredient, long-term use will not cause harm to the skin. Therefore, moisturizing products do not need to be replaced. As long as you find a reliable product that suits your skin, you can keep using it.

Of course, due to climate and seasonal changes, appropriate adjustments should also be made, such as using lotion in hot summer and cream in cold winter. It mainly depends on the characteristics of your skin. You can choose lotion or cream from the same brand, or you can choose products from different brands.
