In this article, we want to start from one of the most frequent questions in the skincare world: is it possible to mix two or more cosmetic products to create your "personalized" texture? We asked SKINIUS dermatologists.
Is it true that skin gets used to dermocosmetics?
We asked our dermatologists if skin can actually become addicted or accustomed to a dermocosmetic product, so much so that its functions are nullified. In reality, our experts clarify that there is no direct mechanism for the skin to become resistant to a dermocosmetic product over time. However, skin changes and dermatological needs can be influenced by external factors such as climate, medication intake, lifestyle, hormonal imbalances, and other possible skin problems. It is therefore normal for the perception of a cream or serum on the skin to change over time depending on the season, certainly not because the skin has gotten used to it. In some cases, this phenomenon may not even occur, and the skin might find its ideal comfort with a dermocosmetic product all year round for many years.
Can we mix products?
The European Commission recently adopted a proposal to revise the GPSD (General Product Safety Directive, which covers all products not regulated by specific directives and/or regulations), which, among other things, emphasizes the need for a safety profile also for products marketed online.
However, the problem of "homemade mixes" of several cosmetics resurfaces, for which, in the spirit of Regulation 1223/2009 (Cosmetics Regulation), this practice is strongly discouraged. Why? A "new" cosmetic product (resulting from the mix) would be created, for which the safety has not been tested in any way. In fact, the safety profile of the resulting mixture would not be known, creating a potential risk for the consumer.
The PIF and product safety
According to Regulation 1223/2009, every company that places a product on the market must legally provide each product with a PIF (Product Information File), a technical dossier that also includes the Cosmetic Product Safety Assessment as marketed by the manufacturer. It is clear that by mixing several products, it is no longer possible to guarantee the safety profile of the resulting mixture. This is why the practice of "mixing" is strongly discouraged, and its regulation is also a subject of discussion within the European Commission.
The Commission has emphasized that the increase in online sales has led to the need for a new set of safety rules to protect consumers and reduce the risks associated with incorrect at-home use of products, including the "mixing" of products, which is often superficially promoted through social networks. Obviously, the updated Regulation will affect both products distributed online and through traditional channels.
No to Mixing, Yes to Layering
To get the most out of your beauty routine, you don't need to mix products; rather, you should proceed step by step, or layer applications. This technique is called layering. Layering is considered safe and recommended because by waiting between applications, it is possible to better manage any potential problems.
