The article from Iltalehti highlights the growing popularity of vitamin C as a skin care ingredient, lauded for its ability to brighten and enhance the skin due to its antioxidant properties. While vitamin C is known to provide numerous benefits, including protection against environmental stressors such as pollution and UV radiation, it may not be suitable for everyone, particularly during winter when skin sensitivity can increase. Cosmetologist Anu Levy emphasizes the importance of using vitamin C properly to avoid adverse skin reactions.

In colder weather, skin is more vulnerable due to harsh external conditions and low humidity indoors, which can lead to moisture loss and dullness. The article advises that Finnish people should be cautious with their vitamin C usage during these months. Proper application can help maintain skin health and ensure that users obtain the maximum benefits without triggering any negative side effects.

Overall, the piece serves as a reminder to treat vitamin C as a beneficial but potentially reactive component of skin care, encouraging readers to seek professional advice and consider personal skin types before incorporating it into their routine, especially in winter.
