In our daily skincare routine, primer is often regarded as an indispensable step. However, many people still have doubts about the true purpose of primer and its relationship to sunscreen. Today, we will delve into this topic.
What is primer? Essentially, its primary function is to create a barrier between the skin and the external environment, preventing harmful substances from penetrating the skin. Many are confused about how to use primer and often ask how to pair it with other skincare products. Generally, the proper application sequence is to first apply toner, then lotion, followed by primer, and finally sunscreen. However, for busy urban dwellers, this skincare routine may seem overly complicated.
Can primer be used as sunscreen? Although primer contains some sun-blocking ingredients, its sun protection efficacy is not sufficient to replace dedicated sunscreen products. A common misconception is that merely using primer can shield against UV rays. In reality, to achieve effective sun protection, one must still use specialized sunscreen and ensure an adequate amount is applied.
For those with oily or sensitive skin, a thick primer may clog pores and increase the risk of breakouts and acne. Therefore, for friends with more fragile skin conditions, it is crucial to choose primers carefully to avoid exacerbating skin issues.
There are also doubts regarding whether primer can effectively block harmful substances in the air. The ingredients in primer primarily consist of moisturizers and sunscreens, and whether they can truly block harmful substances like PM2.5 is still subject to further research.
In urban environments, when the air is cold and polluted, our skin often feels uncomfortable and may exhibit allergic reactions. This could be due to toxic substances in the air, such as polycyclic aromatic hydrocarbons that can damage the skin. Therefore, in addition to relying on primer, it is recommended to use products with anti-inflammatory and antioxidant ingredients, such as Vitamin C and Vitamin E, to enhance the skin’s overall resilience.
The question of whether primer can block cosmetics also prompts reflection. If cosmetics are genuinely harmful, why do we continue to use them? Ultimately, all products interact with one another.
In summary, skincare need not be complicated. A simple and effective skincare routine is key to ensuring healthy skin. For many busy individuals, finding a suitable skincare method and avoiding excessive product layering is the best way to achieve healthy skin.
