Weather determines not only our mood but also the condition of our skin. We constantly seek ideal conditions: not too hot, not too cold, rain that washes away dust but not the protective layer. But there is no ideal. Every weather is a compromise. What is really beneficial and what is harmful? Let's analyze it in detail.Sun: the main enemy and the best friendThe sun is life. Without it, there would be no vitamin D, no good mood, no tan. But for the skin, the sun is a two-faced Janus. On one hand, moderate UVB radiation stimulates the synthesis of vitamin D, which strengthens bones and immunity. On the other hand, an excess of UVA and UVB destroys collagen and elastin, causing photoaging, hyperpigmentation, and, in the worst case, skin cancer. The best for the skin is the sun in moderate doses. 15-20 minutes a day (before 11 am or after 4 pm) is beneficial. Anything more is already a risk. Therefore, the sun is not an enemy but a dangerous partner with whom you need to maintain distance. Use SPF creams, wear hats, and don't try to get a chocolate tan in one day. The skin will thank you.Heat: evaporation and inflammationHeat is a test of strength. At high temperatures, the skin loses moisture faster than you can drink water. Pores expand, more sebum is released, leading to clogged pores and acne. Heat provokes redness in people with rosacea. But there is also a plus: in heat, blood circulation increases, the skin receives more nutrition. The main problem is dehydration. If you don't drink 2-3 liters of water a day, the skin becomes dry, thin, prone to peeling. The best solution in heat is light moisturizing gels, thermal water in spray, and no foundation. And don't forget about the shade.Cold: constriction and protectionCold constricts blood vessels, reduces sweating, and slows down metabolism in the skin. In the short term, this may even improve tone — the skin becomes firm. But long-term exposure to the cold without protection leads to chapping, cracks, peeling. The ... Read more
