According to the International League of Dermatological Societies (ILDS), sunscreen is an essential product in the daily skin care routine because it protects the skin from the harmful effects of UV rays, the main cause of premature skin aging and the risk of skin cancer. Therefore, using sunscreen before makeup not only helps protect the skin but also enhances the skin's ability to retain moisture, especially sunscreens that contain moisturizing ingredients. This makes sunscreen a potential choice for foundation primer.
However, not all sunscreens are suitable as a base. Some sunscreens have a thick and sticky texture, which can make makeup look uneven or clog pores, causing acne. On the contrary, if you choose sunscreens with a light and easily absorbed texture, they can help create a thin layer of foundation, making the skin look natural and helping makeup last longer.
Today, many modern sunscreens also contain antioxidants, which help protect the skin from environmental factors and UV rays, while also helping to brighten the skin.
Another important point is that the effectiveness of sunscreen can be reduced if not enough product is used. When only a thin layer is used as a primer, the amount of sunscreen may not be enough to provide effective protection. Therefore, if you decide to use sunscreen as a primer, you need to make sure you use the recommended amount, and consider reapplying it every few hours, especially when exposed to a lot of sunlight.
